Posterior Capsular Rent Research Articles

Finger-Controlled Nonultrasonic Lens Extractor.

To report initial surgical experience and learning curve with a novel finger-controlled, ultrasoundless lens extractor device and provide insights for future surgical endeavors. Bascom Palmer Eye Institute (Miami, FL). Single-center, non-comparative, retrospective, consecutive case series. 61 eyes of 51 individuals with cataract. All surgeries were performed with the miCOR® 700 lens extractor (Carl Zeiss Meditec Inc, Dublin, CA) by a single experienced physician. Nuclear density was graded preoperatively. Corrected distance visual acuity (CDVA), intraocular pressure (IOP) and pachymetry were evaluated pre- and postoperatively. Surgical videos were reviewed to collect data on time for each surgical step and complications. Regression analyses assessed the learning curve, performance improvement and effects of nuclear density on surgical time and postoperative pachymetric variation. Subjects had a mean age of 72.2 ± 7.6 years. Increased surgical experience significantly reduced procedure time (P < 0.001), nuclear removal time (P = 0.018) and cortex removal time (P = 0.002). Higher nuclear density resulted in longer procedure (P < 0.001) and nuclear removal time (P < 0.001). One posterior capsular rent occurred, not attributed to the lens extractor. No thermal damage to the corneal wound was observed. Postoperative CDVA improved significantly (P < 0.001 for eyes without ocular comorbidities, P = 0.016 for eyes with ocular comorbidities). All cases of corneal edema and IOP spikes resolved within a month. The miCOR® 700 lens extractor offers an innovative, cost-effective approach to cataract surgery. Further research is needed to compare it with conventional phacoemulsification techniques.

Manual-delineation and dissection technique for posterior polar cataract

In posterior polar cataract (PPC), the posterior capsule is weak or dehiscent. This can lead to posterior capsular rent at any time during cataract surgery, leading to complications. Various techniques have been used to manage such cataracts, and modifications are advised at each and every step of cataract surgery. We describe a new technique in which a blunt chopper is used to manually delineate the epinucleus from the nucleus at 360 degrees, and the nucleus is chopped and removed by phacoemulsification. Then, the chopper is inserted in the plane between the capsule and the epinucleus, and manual dissection is performed, followed by rotation and pushing it centrally. This epinucleus that is separated is aspirated simultaneously. Thus, with no pressure fluctuations and undue stress on the posterior capsule from the fluid jets, we manage to do surgery in tricky cases of PPCs successfully using manual delineation and dissection.

Optic capture of the intraocular lens in posterior capsular rupture

A 67-year-old female had a left eye posterior polar cataract (PPC) with a thin intact posterior capsule (PC) with nuclear sclerosis grade V (as per the lens opacities classification system III) and an intraocular lens (IOL) in the sulcus with an absent PC in the right eye. On examination, her best-corrected visual acuity (BCVA) was 6/6 (+1.00/+1.50 × 10) and 6/60 (plano) for right eye (OD) and left eye (OS), respectively. She underwent left eye phacoemulsification cataract surgery, and intraoperatively, capsular rupture occurred which was noticed before completion of the last quadrant. No vitreous leakage occurred, and a three-piece IOL was implanted in the sulcus and an optic capture was done. At one-month follow-up, her left BCVA was 6/6 (0.50 DS/+1.25 × 10) with normal IOP, and the IOL was well centered with an oval-shaped anterior capsule covering the optic anteriorly, and a ruptured PC was seen as two parallel lines. We have discussed various important steps in the management of PPC and posterior capsular rent in this paper with the illustrative image of an optic capture of the three-piece IOL in posterior capsular rupture.

Visual outcome of cataract surgery by phacoemulsification in diabetic versus non-diabetic patients: A comparative study

This study aims to evaluate and compare the results of phacoemulsification cataract surgery performed on diabetic patients with those of non-diabetic patients. The primary objective was to compare the visual outcome of phacoemulsification cataract surgery in diabetic patients and non-diabetic patients, and the secondary objective was todetermine the final visual outcome following phacoemulsification cataract surgery in diabetics and non-diabetics.A comparative study of the overall 300 eyes of the patients, in which 150 eyes were diabetic and 150 eyes were non-diabetic, underwent phacoemulsification cataract surgery with posterior chamber intra ocular lens implantation. Age, sex, follow-up, preoperative and postoperative best corrected visual acuity and post-operative complications were evaluated. Out of the 300 eyes of the patients, 150 eyes were diabetic and 150 eyes were non-diabetics. Phacoemulsification with posterior chamber intra ocular lens implantation was done in all patients. Follow up duration was 6 weeks. Postoperatively, 6 weeks after surgery, 31.7% of patients had BCVA of 6/9 or better in diabetic group while 36.3% of patients had BCVA of 6/9 or better in non-diabetic group. The difference in BCVA between two groups at postoperative 6 weeks was found to be statistically significant p value of &amp;#60;0.001. Post-operative complications included wound leak, striate keratopathy, folds in descemets membrane, corneal haze or edema, iritis, posterior capsular rent, cystoid macular edema, iridodialysis. The incidence was higher in the diabetic group as compared to non-diabetics. Overall, the final visual outcome was better in non-diabetic group as compared to diabetic group. Diabetics are more likely to develop intra operative and postoperative complications. Thus, special care should be used both throughout the surgical procedure and the post-operative period.

Systemic Vascular Parameters in Ocular Pseudoexfoliation.

Background Pseudoexfoliation syndrome (PEX) is characterized by a dandruff-like substance in the anterior chamber, composed of various glycoproteins that have an unclear origin. Its deposition is observed on the pupillary margin, lens zonules, and trabecular meshwork. Proteomic studies have identified numerous proteins in the affected individuals, suggesting associations with systemic conditions like heart disease, stroke, and Alzheimer's disease. However, the systemic associations of PEX remain inconclusive, particularly in regions like southern India. Materials and methods A cross-sectional study was conducted on 114 participants. Pseudoexfoliation was graded as mild, moderate, and severe as per standard photographic grading. Systemic examinations included blood pressure measurements, electrocardiography (ECG), and blood investigations for serum lipid profile, fasting and postprandial blood sugar levels, and serum C-reactive protein levels. Small incision cataract surgery was performed for all the patients. Intraoperative complications and postoperative status were recorded. Results Thirty-eight patients (33.3%) had mild PEX, 44 (38.6%) had moderate PEX, and 32 (28.1%) had severe PEX. Hypertension was present in 54 participants (47.4%), diabetes in 21 (18.4%), coronary artery disease in nine (7.9%), and cerebrovascular accidents in three (2.6%). The mean systolic blood pressure was 140.39 mmHg and the mean diastolic blood pressure was 90.37 mmHg. Systolic blood pressure exceeded 140 mmHg in 29 participants (90.6%) with severe PEX, while diastolic blood pressure surpassed 90 mmHg in 26 participants with severe PEX, both with a p-value of 0.001. Mean fasting and postprandial blood sugar levels were 103.80 ± 31.81 mg/dl and 131.72 ± 48.24 mg/dl, respectively. Serum lipid profiles showed mean low-density lipoprotein (LDL), very low-density lipoprotein (VLDL), cholesterol, and triglyceride levels of 103.00 ± 34.49 mg/dl, 29.04 ± 15.51 mg/dl, 172.73 ± 43.34 mg/dl, and 129.33 ± 64.65 mg/dl respectively. Electrocardiographic results indicated that 54 participants (47.37%) had abnormal ECG including rate abnormality in 13.2%, conduction defects in 12.3%, ischemic changes in 10.5%, and structural defects in 11.4%. Eighty-seven percent of patients had non-dilating pupils and iris atrophy, 13.2% had zonular dialysis and intraoperatively, 78% had capsulorhexis extension, 49.12% had difficult nucleus prolapse, and 28.95% had posterior capsular rent. Conclusion This study highlights the significantly elevated parameters of systemic vascular diseases in PEX patients, like elevated blood pressure and more frequent cardiac anomalies, emphasizing the need for comprehensive systemic evaluation and careful preoperative assessment for ocular comorbidities.

Anterior vitrectomy: Simplified.

Anterior vitrectomy is a skill all cataract surgeons should develop and master. Every surgeon will have complications at some point in his/her career. Complication management should be part of the surgical training for all cataract surgeons. Posterior capsular rent does not translate to poor visual outcomes. If managed properly, excellent visual outcomes can be achieved and complications minimized. We aim to simplify the anterior vitrectomy procedure by this video. This video will serve as a step-by-step practical guide to the intraoperative management of posterior capsular rent by simplifying the anterior vitrectomy procedure. This video will demonstrate how to tackle the dreaded complication of a posterior capsular rent with vitreous disturbance, and achieve optimal postoperative outcomes. We demonstrate how a PCR appears, and once identified, how to proceed. In addition, nuances regarding foot positions and different vitrectomy modes are included. Biaxial vitrectomy is explained. Lens placement post-PCR is demonstrated. Furthermore, a brief about postoperative management is included. https://youtu.be/dTo7sMpe8h8.

Profile of Cataract Surgical Patients at the National Eye Centre, Kaduna, Nigeria.

Cataract surgery has evolved over the years. This study aims to highlight the profile of the patients that underwent cataract surgery at a tertiary hospital with emphasis on patient demographics, surgical techniques performed, intraocular lens powers implanted, and the complications managed. A retrospective cross-sectional descriptive study of all patients who had undergone cataract surgery within two years at the National Eye Centre, Kaduna, Nigeria. Data extracted from the electronic version of the manual cataract surgical records included the patient's age, sex, comorbidities, technique of cataract surgery performed, the intraocular lens powers implanted, and complications encountered. Intraoperative and postoperative complications up to the twelfth week were considered. All patients had biometry-guided intraocular lens implantation. One thousand four hundred and seventy- two (1,472) patient records of all ages met the inclusion criteria with a male-female ratio of 1.4:1. The mean age was 51.4 ± 22.6 years. The difference in the mean age of the sexes was statistically significant (p=0.01) and 95% CI was 7.37- 10.40 years. Glaucoma was the commonest ocular comorbidity 142(9.65%) and only 5% (74) had systemic comorbidities. The mean intraocular lens (IOL) power was 19.25 ± 1.8Diopters (Range 10.5D to 26D). The commonest surgery performed was small incision cataract extraction with posterior chamber intraocular lens implant (SICS + PCIOL) 91.2% followed by Trabeculectomy with SICS + PCIOL (3.87%). Phacoemulsification accounted for 2.72% of surgeries. Intra-operative complications were posterior capsular rent in 7.1% (104) and vitreous loss in 4% (58). The commonest post-operative complications were corneal edema6.9% (103) and striae keratopathy 4.6% (68). Most cataract patients were male, above 50years of age and likely to be older than the females at surgery. The most performed surgical technique was small incision cataract surgery with posterior chamber intraocular lens implantation (SICS + PCIOL) while the mean intra-ocular lens power was 19.25 ± 1.8Dioptres. Globally accepted cataract surgical techniques utilizing recent technological advancements were employed with biometry-guided intraocular lens power calculation and implantation. Complications fell within the accepted global rates.

AYURVEDIC MANAGEMENT OF POSTERIOR POLAR CATARACT: A CASE STUDY

Posterior Polar Cataract is the rare subset of congenital cataracts resulting in defective vision. It follows an autosomal dominant inheritance pattern and is occasionally sporadic due to the high incidence of intraoperative complications, which include posterior capsular rent, nucleus drop, etc. Posterior Polar Cataract is a surgical challenge for ophthalmologists. Ayurveda cataracts can be described in the context of Timira, Kacha and Linganasha. Timira is a disease of the Drishti Mandala, which presents with blurred vision initially, and if left untreated, it will progress to Kacha, which, if neglected, will lead to Linganasha. Linganasha is the last stage, where there is complete vision loss. A 37-year-old female patient complaining of blurred vision for distance and glare at night for two years is presented here. She was diagnosed with Posterior polar cataract one year back. The patient underwent Ayurveda treatment of shodhana and shamana chikitsa after properly assessing Rogi and Roga bala, which includes- Kayavirchana, Shirovirechana, Kriyakalpas (Akshitarpana, Anjana) and Rasayana prayogas. Assessment after the above treatment has shown improvement in the patient's visual acuity. From this study, it can be concluded that Ayurvedic treatment can preserve and give a better quality of vision to the patient of Posterior Polar Cataract, as surgery includes a high risk of capsular rupture and vitreous loss that can lead to worse visual outcomes.

Prevalence of Posterior Capsular Rent in Mature Cataract During Manual Small Incision Cataract Surgery

Introduction: Manual small incision Cataract surgery (MSICS) is the most common intraocular surgery performed worldwide and has advanced technically in recent years. However, as in all surgeries, complications continue depending on the surgeon, surgical technique, and patient. In order to reduce the complications in cataract surgery, many studies have been carried out to detect ocular and systemic risk factors and to take precautions against them. Materials and Methods: Mature cataract patients who can perceive light or hand motion with preoperative vision make up the study population. Preoperative assessments, including comprehensive ophthalmic evaluations and demographic data collection, are performed for every patient who is enrolled. Results: Among the 60 cases that underwent manual small incision cataract surgery, there were 13 instances of posterior capsular rent (PCR). In general, the people who had PCR were 63.86 years old. PCR happened for various reasons. Conclusion: The study found a notable occurrence of posterior capsular rent (PCR) in patients who underwent manual small-incision cataract surgery, with 13 cases out of 60 surgeries. Potential risk factors for PCR included phacodonesis, zonular dialysis, small pupils, a history of trauma, and high myopia. These findings demonstrate the significance of understanding and managing the risk factors for posterior capsular rent (PCR) in manual small incision cataract surgery to enhance patient safety and surgical outcomes.

Short-term Visual Outcome Following Anterior Chamber Intraocular Lens Implantation—The Experience of a Rural Teaching Hospital

Purpose: To report the indications, frequency and short-term visual outcome of anterior chamber intraocular lens implantation (ACIOL) in a rural tertiary hospital; as well as to describe the reasons for poor visual outcome following ACIOL implantation. Methods: This was a retrospective descriptive study of all patients aged at least 18 years who underwent cataract extraction and implantation of ACIOL between January 2004 and May 2023. Information retrieved from the case records included preoperative visual acuity, indication for ACIOL implantation, first-day postoperative visual acuity, and 6 weeks postoperative visual acuity. Results: A total of 133 eyes of 126 patients were reviewed in this study. The mean age was 60.9 years, with a male-to-female ratio of 1.7:1. The most common indication for ACIOL use was a posterior capsular rent (70.7%). The first-day postoperative visual acuity was 6/18 or better in 7 (5.3%) patients, and by the sixth postoperative week, this proportion had increased to 28.6% (38 patients). The most common complication on the first day post-op was striate keratopathy (72.9%), while the most common at 6 weeks was pseudophakic bullous keratopathy (21.1%). Conclusion: Although complications were noted with the use of ACIOLs, improvement in visual acuity was observed at 6 weeks. ACIOLs may still be relevant in settings where automated vitrectomy equipment is not readily available, but the availability of expertize is required for its implantation and the complication profile of ACIOLs must always be taken into consideration.

Study of Surgical and Visual Results and Complications of Manual SICS in a Tertiary Care Medical College in India

BACKGROUND&#x0D; Small-incision cataract surgery (SICS) is a widely practiced surgery in developing nations. Its cost-effective nature and compatibility with high-volume facilities make it a valuable option, offering favorable visual outcomes for most patients. This study was done to evaluate the visual results of SICS procedures performed at a tertiary care center in Urun, Islampur and investigate the factors contributing to suboptimal visual outcomes.&#x0D; METHODS&#x0D; A total of 200 cataract patients were enrolled in this study. The research encompassed a comprehensive analysis of intraoperative and postoperative complications. There was a comparison made between postoperative visual acuity (VA) and preoperative VA, with a dedicated examination of the determinants of diminished visual outcomes. Follow-up evaluations were carried out on days 1, 3, 7, 14, and 30.&#x0D; RESULTS&#x0D; The average age of the patient cohort was 63 years, with a slightly higher representation of females (52%) compared to males. The most frequently encountered surgical complication with 5.5% incidence was striate keratopathy, which was then followed by iris damage which had an incidence of 4.5%. The other common complications included posterior capsular rent (PCR) with vitreous loss (3.5%), hypotony (0.10%), intraocular lens decentration (0.50%), surgically induced astigmatism (0.20%) and endophthalmitis (0.50%). Notably, 98% of the patients achieved visual acuity exceeding 6/18. Complications associated with suboptimal visual outcomes (&lt;6/18) were primarily attributed to posterior capsular rent, surgically induced astigmatism, and endophthalmitis.&#x0D; CONCLUSIONS&#x0D; While SICS may carry a certain risk of complications, the majority of patients can attain favourable visual outcomes.

Clinical Profile of Cystoid Macular Edema Following Small Incision Cataract Surgery

BACKGROUND&#x0D; This study was conducted to determine the incidence of cystoid macular edema after small incision cataract surgery by means of OCT, study the clinical profile and compare the incidence in non-diabetic and diabetic patients with and without retinopathy.&#x0D; METHODS&#x0D; This was a hospital based prospective study, conducted among 325 patients in the age group of 40 to 85 years who underwent Small Incision Cataract Surgery [SICS] conducted in Sree Mookambika Institute of Medical Sciences, Kulasekharam, Kanyakumary District, Tamil Nadu, over a period of one year from January 2022 to December 2023, after obtaining clearance from the institutional ethics committee and written informed consent from the study participants.&#x0D; RESULTS&#x0D; The incidence of CME was higher among diabetic patients when compared with non-diabetic patients and was statistically significant. Patients with a history of uveitis had a statistically significant increase (p&lt;0.05) in the incidence of CME in the 6th postoperative week. Patients with complicated surgery with iris prolapse, vitreous prolapse, difficult nucleus delivery and posterior capsular rent had an increased incidence of CME. This was statistically significant (p&lt;0.05) during all three postoperative evaluations.&#x0D; CONCLUSIONS&#x0D; Following cataract surgery, 18.8% of patients developed cystoid macular edema six weeks after the procedure. Three months following surgery, 13.2% had CME, which further declined to 5.2% at six months after surgery. The incidence of clinically significant cystoid macular edema was 4% at six weeks after surgery. It further declined to 1.2% at 3 months after surgery and was present in only 0.6% at 6 months after surgery. The incidence of CME was higher among the diabetic patients throughout the study when compared with non-diabetic patients and was statistically significant (p&lt;0.01). The association between the severity of diabetic retinopathy and the incidence of cystoid macular edema was not statistically significant. Patients with a history of uveitis had a statistically significant increase (p&lt;0.05) in the incidence of CME in the 6th postoperative week. Patients with complicated surgery with iris prolapse, vitreous prolapse, difficult nucleus delivery and posterior capsular rent had an increased incidence of CME. Patients not using topical NSAIDS were found to have an increased incidence of CME.

Assessing the validity of flap motility sign in predicting the extent of anterior capsular tears in phacoemulsification.

Capsulorhexis is an integral step of cataract surgery, and continuous curvilinear capsulorhexis is crucial during phacoemulsification to prevent intraoperative complications. However, sometimes during phacoemulsification in complicated and hard cataract cases, rhexis extension may occur, resulting in posterior capsular rent, nucleus drop, cortex drop, and aphakia. It may not always be possible to continue with phacoemulsification in all cases. In this perspective, the authors describe a novel flap motility sign (FMS) to predict the extent of anterior capsular tear during phacoemulsification. A total of 21,678 patients underwent phacoemulsification for three years, from July 2016 to June 2019. One hundred and twenty-one patients had an anterior capsular tear. There were 102 cases (84.3%) with pre-equatorial tears and 19 cases (15.70%) with postequatorial tears. All pre-equatorial flaps were everted and fluttering, and all postequatorial flaps were inverted and nonfluttering. Posterior capsule rupture (PCR) was observed in all 19 cases of postequatorial flaps (100%). No PCR was observed in patients with fluttering and everted flaps (0%). In-the-bag and scleral-fixated intraocular lens implantations succeeded in pre-equatorial and postequatorial tears, respectively. There was no case of a nucleus drop. This study validates FMS as a predictor for identifying the extent of anterior capsular tears, thereby determining the endpoint of safe phacoemulsification and the site for intraocular lens implantation. Pre-equatorial tears allow for the continuation of safe phacoemulsification and in-the-bag intraocular implantation. Postequatorial tears necessitate timely conversion to small-incision cataract surgery or extracapsular cataract extraction.

Arthroscopic Posterior Labral Repair for Posterior Shoulder Instability

Background: Posterior shoulder instability occurs in 2% to 10% of shoulder instability cases and is more commonly due to repetitive microtrauma as opposed to the more traumatic onset seen in anterior shoulder instability. In posterior instability, the posterior capsulolabral complex becomes attenuated or torn. Thus, surgical treatment aims to restore the posterior soft-tissue stabilizers typically with an arthroscopic, suture-anchor-based labral repair. Indications: Surgical indications include posterior instability with traumatic cause and associated soft-tissue and/or osseous pathology and for those patients with repetitive microtrauma who have failed nonsurgical management. Technique Description: Following diagnostic arthroscopy, the glenoid is prepared using an arthroscopic elevator, rasp, and chisel first viewing from the posterior portal, then from the anterior portal using a 70° arthroscope. An all-suture anchor is placed at the 7 o’clock position using a curved guide which obviates the need for an accessory 7 o’clock portal. The repair suture is then shuttled through the labrum using a suture lasso and monofilament. This repair suture is then shuttled through the suture anchor using the inbuilt shuttling fiberlink. The repair suture is then tightened to secure the labrum. The remainder of the repair uses knotless 2.9-mm biocomposite suture anchors and free suture tape as the all-suture anchor and associated curved guide are typically only necessary for the angle of the most inferior portal. Following a 3 to 5 anchor repair, the posterior portal capsular rent is closed to avoid leaving a stress riser. Posterior capsular closure is achieved using monofilament suture passed with a birdbeak and tied blindly in the subacromial space. Results: In a study of 200 shoulders at 36 months, patients undergoing posterior stabilization had improvements in their American Shoulder and Elbow Surgeons (ASES) scores and improvements in stability, pain and function. Ninety percent of patients were able to return to sport and 64% of patients returned to the same level. Failure rate was low at 6%. Discussion/Conclusion: Posterior labral repair is a technically nuanced but reliable procedure for the management of posterior instability.

Outcomes of "Complex" Cataract Surgeries Performed by Long-Term Glaucoma Fellows in a Tertiary Eye Centre from Eastern India.

To evaluate the outcomes of operating on "complex cataracts" by the glaucoma fellows. This was a retrospective study done at a tertiary referral eye care centre in eastern India. After obtaining IRB approval, a retrospective chart review of all patients who underwent "complex" cataract surgery by one of four long-term (2 years) glaucoma fellows between January 2016 and November 2020 was conducted. 'Complex' was defined as cataracts complicated with pseudoexfoliation syndrome, phacodonesis with or without blunt ocular trauma, posterior polar cataract, small pupil, co-existent corneal opacity or uveal coloboma, post-glaucoma filtering surgery, post-vitreoretinal surgery, co-existent glaucoma or post-laser iridotomy and monocular patients. Out of a total of 677 eyes done by the glaucoma fellows during the study period, 83 eyes had complex cataract surgery and completed the six-week post-operative follow-up. Intraoperative surgical complications like posterior capsular rent or vitreous loss were noted in 36 of the cases. Thirty of the eyes were left aphakic. Despite a high rate of complications, the LogMAR best-corrected visual acuity (mean ± standard deviation) improved from the preoperative level of 1.7 (±0.5) to 1.0 (± 0.8) at post-operative six weeks, significant at p < 0.001. As far as the surgeon's experience was concerned-less than or more than a year since joining the fellowship-there was statistically no difference in the final visual acuity. The group with greater experience had shorter surgical time and lesser complications though this difference was not statistically significant. This is the first study in the literature reporting the outcomes of "complex" cataract surgery performed by glaucoma fellows. Though high rates of postoperative complications were noted in this study, the mean best-corrected visual acuity improved significantly in all eyes after the surgery.

Outcomes of manual small incision cataract surgery (MSICS) in eyes with corneal opacity.

To report the outcomes of manual small incision cataract surgery (MSICS) in eyes with corneal opacity. Tertiary care ophthalmic hospital. Retrospective study. This retrospective study included 286 eyes of 286 patients having cataract with a pre-existing corneal opacity who underwent manual small incision cataract surgery (MSICS) at a tertiary eye institute between January 2020 and January 2022. Data were retrieved from electronic medical records, and we documented demographics, history, detailed anterior and posterior segment examination, cataract grading, pre- and post-operative vision, intra-operative complications and its management, and post-operative course. All these parameters were recorded at the baseline visit, day 1 and at 1month post-operatively. Two hundred eighty-six eyes having cataract with a pre-existing corneal opacity which underwent MSICS were evaluated. Corneal opacity was graded as nebular, nebulo-macular, macular and leucomatous types; nebular opacity being the most common. Trauma was the most common cause of opacity followed by infective keratitis. Intra-operative complication rate was 4.89%; which included-7 posterior capsular rent with vitreous disturbance, 2 zonular dialysis, 2 iridodialysis, 2 eyes with aphakia and 1 with Descemet membrane detachment. On follow-up, 6 patients had decentered intraocular lens and 10 had residual cortex. Median logMAR vision improved significantly (p < 0.001) from 1.08 (5/60) pre-operatively to 0.3 (6/12) post-operatively. MSCIS is efficient in providing favorable visual outcomes in patients where corneal opacity makes it difficult for the surgeon to perform a phacoemulsification surgery.

POST OPERATIVE ASTIGMATISM AFTER MANUAL SMALL INCISION CATARACT SURGERY REQUIRING SCLERAL TUNNEL SUTURING

Purpose: To study postoperative astigmatism after manual small incision cataract surgery (MSICS) which required scleral tunnel suturing. Materials And Methods: This is a prospective study of 120 cataract patients attending ophthalmology out patient department from December 2021 to May 2022 who underwent MSICS which required scleral tunnel suturing. Preoperative evaluation was done. MSICS was performed in all cases and scleral tunnel suturing was performed in these cases as there were complications like shallow anterior chamber, button hole, premature entry, iris prolapse and posterior capsular rent. Suturing was done to stabilise sclerocorneal wound. In cases with posterior capsular rent inspite of stable wound, suturing was done to avoid post op infections like endophthalmitis. Patients were followed up at 1week, 4 weeks, 6 weeks and 8 weeks postoperatively. Results: Out of 120 patients 72 patients (60%) had WTR astigmatism and 48 patients(40%) had ATR astigmatism preoperatively. After 8 weeks post suture manipulation among WTR astigmatism patients 70.61% had &lt;1 D astigmatism and among ATR patients 72.91% had &lt;1 D astigmatism. 70% patients had BCVA6/9 or better, 25.83% had BCVAbetween 6/12 -6/24 and 4.1% had visual acuity &lt;/= 6/36. Conclusion: Scleral tunnel suturing in MSICS results in surgically induced astigmatism. It affects the visual outcome signicantly. With optical correction and suture manipulation, correction of astigmatism is possible. Hence scleral tunnel has to be attempted in unavoidable cases

Visual Outcome and Complications in White Mature Cataracts after Phacoemulsification.

To identify risk factors and perioperative complications and assess postoperative visual outcome in patients of white mature cataracts undergoing phacoemulsification surgery. This cross-sectional study was conducted on 46 patients of white mature cataract undergoing phacoemulsification. Preoperatively, a detailed ocular examination was done, and anterior chamber depth (ACD) and lens thickness (LT) were measured on ultrasound biomicroscopy. Intraoperative and postoperative complications (on days 1, 7, and 30) and best-corrected visual acuity on postoperative day 30 were noted. The mean age of patients was 60.78 ± 9.001 years. The study group consisted of 41.3% of males and 58.7% of females. 8 (19.56%) cases encountered complications during phacoemulsification surgery. The intraoperative complications were capsulorhexis-related in 5 (10.86%) patients, posterior capsular rent in 2 (4.3%) patients, and 1 (2.17%) case had zonular dialysis. There was no difference in mean ACD and LT in cases who developed complications and those who underwent uneventful surgery (P > 0.05). The commonly observed postoperative complications on day 1 were corneal edema (41.3%), anterior chamber flare (45.65%), and cells (39.13%) which resolved with routine topical medications. All patients showed a significant reduction in postoperative intraocular pressure (P < 0.001). A total of 37 (80.43%) eyes regained vision between 6/6 and 6/9 postoperatively (P < 0.001). Phacoemulsification surgery is safe in white mature cataract that results in significant visual improvement. Common intraoperative complications are capsule related, while frequently encountered postoperative complications are corneal edema and anterior chamber reaction. Preoperative ACD and LT have no role in predicting intraoperative complications.

Visual outcome and complications of small-incision cataract surgery.

Small-incision cataract surgery (SICS) is a commonly performed procedure in developing countries. It does not require expensive machines and can be safely done in high-volume centers also yielding good visual outcomes in the majority of patients. The objective of our study was to assess visual outcomes after SICS conducted at a tertiary care center in South Gujarat and also assessment of various complications responsible for poor visual outcomes. Three hundred and fifteen cataract patients were included in the study. An assessment of intraoperative and postoperative complications was done. Postoperative visual acuity assessment was done and compared with preoperative visual acuity of the patient and factors responsible for poor visual outcomes were assessed. A follow-up examination was done on days 1, 3, 7, 14, and 30. The mean age group of patients was 59.3 years. Females were slightly more (53.3%) in number as compared to males. The most common surgical complication encountered were striate keratopathy (6.35%), followed by iris damage (5.71%), posterior capsular rent (PCR) with vitreous loss (3.14%), hypotony (0.63%), intraocular lens decentration (0.63%), surgery-induced astigmatism (0.63%), choroidal detachment (0.32%), endophthalmitis (0.32%), and hyphema (0.32%). About 95.87% of patients had vision better than 6/18. Complications associated with poor visual outcome (<6/18) were PCR, endophthalmitis, choroidal detachment, and surgical-induced astigmatism. Although SICS can have a significant chance of complications, good visual outcomes can be attained in the majority of patients.

VISUAL OUTCOMES IN DIABETIC PATIENTS FOLLOWING CATARACT SURGERY

Introduction:- To determine visual outcome and intraoperative and postoperative complications following cataract surgery in diabetic patients with visually signicant cataract. This is a prospective interventional Materials And Method :- study of 100 diabetic cataract patients attending outpatient department of ophthalmology in a tertiary eye care government hospital who underwent manual SICS from October 2021 to January 2022 . Intra-operative and post-operative complications were noted on follow up. Out of 100 pati Results:- ents,68% of patients had post operative visual acuity 6/12 or better. Most common complication noted intraoperatively was posterior capsular rent and post operatively was striate keratopathy (38%) which was mild in 22% cases. Other complications noted include vitreous loss, corneal edema , serous uveitis, brinous uveitis with posterior synechiae, posterior capsular opacity, pseudophakic bullous keratopathy and clinically signicant macular edema. Conclusion:- Visual improvement was seen in diabetic patient with cataract following surgery. Poor visual outcome in diabetics was mainly due to retinopathy, maculopathy or surgical complications. Monitoring for progression of diabetic retinopathy in postoperative period and timely treatment may enhance visual outcome
