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 <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.

Poor visual outcome and associated factors among patients underwent cataract surgery at Debre Markos and Felege Hiwot comprehensive specialized hospitals, Northwest Ethiopia, 2023

ObjectiveThis study aimed to determine the proportion of poor visual outcome and associated factors among adult patients who underwent cataract surgery at Debre Markos and Felege Hiwot Comprehensive Specialized Hospitals in northwestern Ethiopia in 2023.MethodsA hospital based cross-sectional study was conducted on 418 adult patients who had undergone cataract surgery from June 07 to August 07, 2023. Patients were recruited using systematic random sampling with an interval of 2. A pre-tested semi-structured questionnaire, medical record review, and ophthalmologic examination were used to collect data. The collected data was entered into Epi-info version 7 and exported to SPSS version 25 software for analysis. Binary logistic regression was used to determine the factors associated with poor visual outcomes of cataract surgery. Variables with a p-value of less than 0.05 in the multivariable binary logistic regression were considered statistically significant.ResultsA total of 408 study participants with a median age of 65 years and a response rate of 97.6% took part. The proportion of poor visual outcomes of cataract surgery from 4 weeks to one year was 25.7% (95%CI: 21.6%, 30.3%). Factors responsible for poor visual outcomes of cataract surgery were intraocular lens implantation without a posterior chamber (AOR = 2.91, 95%CI:1.46,5.80), per-existing central corneal opacity (AOR = 3.83, 95%CI:1.52,9.69), pseudoexfoliation (AOR = 3.91,95%CI:1.39,11.88), age-related macular degeneration(AOR = 3.75, 95%CI:1.22, 11.88), glaucoma (AOR = 3.11, 95%CI:1.06,9.17) and striate keratopathy(AOR = 3.4, 95%CI: 1.11, 10.88).ConclusionIn this study, the proportion of poor visual outcomes of cataract surgery is higher than the World Health Organization recommendation. The study found that implantation of an intraocular lens without a posterior chamber, pre-existing central corneal opacity, pre-existing age-related macular degeneration, pre-existing glaucoma, pseudoexfoliation, and striate keratopathy were significantly associated with poor visual outcomes of cataract surgery. We recommend that ophthalmologists and cataract surgeons prioritize the reduction of surgical complications and pre-existing ocular co-morbidities to enhance post-operative visual acuity. Improving pre-operative assessment and refining surgical techniques like phacoemulsification will aid in achieving this goal.

Outcome of Cataract Surgery among Eye Camp Patients of Eastern Nepal

Background: Outreach camp is helpful for reducing the prevalence of blindness due to cataracts and refractive error. The objective was to evaluate the visual outcome of cataract surgery among camp patients operated at a high volume center of Eastern Nepal. Materials and Methods: Descriptive cross sectional study design was used. The comprehensive eye screening program was conducted and those having cataracts were referred to base hospital for cataract surgery, patients were reexamined at the base hospital again and a small incision cataract surgery with posterior chamber intraocular lens was implanted at Biratnagar Eye Hospital, Biratnagar and Sagarmatha Choudhary Eye Hospital, Lahan. The pre-operative vision was taken during screening and post-operative vision was taken after one-month by performing refraction by trained personnel. Data were extracted from the hospital record; analysis was done using SPSS version 17.0. Descriptive analysis by using frequency, parent age and association was done by using Chi square test with a P-value <0.05 considered as significant. Results: A total of 1426 camp patients were operated. Among them 1113 (78%) were visited after one month post operative follow up at the campsite. There were 744 (52%) female and bilateral affected eyes were 735(52%). Pre-operative presenting visual acuity was <3/60 (37%), which was reduced to (0.2%) after one month follows up of cataract surgery. There was a significant association in pre-operative VA with aided one month to follow up VA. Conclusion: The outcome of the cataract surgery of camp patients operated at base hospitals was good in high-volume hospitals. Follow up after one month was good practice to provide services and measure the outcome of cataract surgery.

Visual Outcomes of Cataract Surgery in Patients with Previous History of Implantable Collamer Lens.

Background/Objectives: This retrospective case series analyzed visual outcomes in patients with a prior history of implantable collamer lens (ICL) implantation who underwent cataract extraction (CE). A secondary aim was to investigate the relationship between vault height and the rate of cataract development. Methods: Visual acuity and refraction measurements were collected after CE at one week, one month and six months. Vault height measurements were correlated to the time until symptomatic cataracts were removed. Results: A total of 44 eyes were analyzed at six months after CE with efficacy and safety indexes of 1.20 ± 1.11 and 1.50 ± 1.06, respectively. In addition, 70% of eyes had a post-operative uncorrected distance visual acuity (UDVA) within one line of pre-operative corrected distance visual acuity (CDVA). Refractive predictability at six months demonstrated that 43% and 69% of eyes were within ±0.25 D and ±0.50 D of SEQ target, respectively. Astigmatism measured by refractive cylinder was ≤0.25 D in 17% and ≤0.50 D in 34% of eyes pre-operatively compared to 40% and 60% of eyes, respectively, at six months post-operatively. Vault heights one week after ICL (p < 0.0081) and one week before CE (p < 0.0154) demonstrated a positive linear regression with the time until CE. Conclusions: This sample population achieved favorable visual outcomes six months after CE, similar to six months after ICL implantation. Patients with a history of ICL implantation will similarly have a good visual prognosis after CE.

Visual outcomes after cataract surgery in monocular compared to binocular patients: a case-control study.

We aimed to identify ocular comorbidities and reasons of blindness in monocular patients and to compare visual outcomes of cataract surgery between monocular and binocular patients. A single-center case-control study was conducted between November 2011 and May 2019 to compare consecutive series of patients needing cataract surgery in Strasbourg University Hospitals, France. Cases were patients with permanent monocular vision loss. Controls were binocularly sighted patients. All patients underwent cataract surgery using phacoemulsification technique. Chart analysis included demographic data, medical history, and surgical determinants data. Student's t tests and Fisher's exact tests were the main methods used for statistical analysis. Each group included 80 patients. The mean age at the time of surgery was significantly higher in monocular than binocular patients (77 vs. 71years, p < 0.001). Thirty-two monocular patients (40%) had ocular comorbidities, compared to only 19 (23%) in the control group (p < 0.05). The leading cause of monocular status was amblyopia caused by strabismus (22 patients, 27.5%). Age-related macular degeneration, open-angle glaucoma, and diabetic retinopathy were the three main ocular comorbidities that were observed in the monocular group. Monocular patients had significantly lower visual acuity than the control group (p < 0.01) before and after cataract surgery. Conversely, improvement in visual acuity after surgery was not statistically different between groups (p = 0.054). There was no statistically significant difference in the rate of surgical complications between groups (p = 0.622). This study illustrates that cataract surgery in monocular patients is not more complicated than in binocular patients, but that it is significantly delayed.

Complication rates in phacoemulsification surgeries performed by trainee residents

Objectives: Phacoemulsification with a foldable intraocular lens is the gold standard of cataract treatment. Studies have shown that various risk factors affect the visual outcome of cataract surgery. One of these is the availability of well-trained surgeons. Here, we are trying to understand how to achieve good surgical outcomes even if the surgeon has low surgical experience. Materials and Methods: A hospital-based prospective study was done from August 2019 to March 2021. After a detailed examination, each patient was scored based on the risk factors associated and classified into various risk groups. A total of 286 patients were studied, out of which consultants operated on 143 patients and 143 patients were operated on by trainee residents. The intraoperative and postoperative complication rates are compared based on the complexity of cases between trainee residents and consultants. Results: About 82.5% of the patients operated by trainee residents and 78.32% of patients operated by consultants belonged to the no-risk group with complication rates of 2.50% and 1.80%, respectively, which was statistically not significant. In the case of patients with associated preoperative risk factors, 36% of patients operated on by trainee residents had complications, and 9.6% of patients operated on by consultants had statistically significant complications. Conclusion: Preoperative stratification and allocation of cases according to associated risk factors help reduce complications, help trainee residents gain essential surgical skills, and give better surgical outcomes for patients.

Evaluation of the impact of binocular versus monocular cataract surgery using Catquest-9SF: a randomized controlled trial.

This prospective, randomized, unmasked, clinical trial aimed to report the visual outcomes of cataract surgery on both eyes versus cataract surgery on one eye in Brazilian patients. This study included patients with bilateral cataracts and binocular visual acuity worse than or equal to 0.3 logarithm of the minimum angle of resolution. The patients were randomly assigned to undergo surgery on one (Control Group) or both eyes (one eye at a time; Intervention Group). Postoperatively, self-reported visual function using Catquest-9SF (primary outcome measure), binocular visual acuity, stereopsis, and ocular dominance (secondary outcome measures) were compared. A total of 151 patients (77 and 148 eyes in the Control and Intervention Groups, respectively) completed the follow-up. Patients who underwent surgery on both eyes exhibited significantly better self-reported visual function (p=0.036) and stereopsis (p=0.026) than those who underwent surgery on one eye. Binocular visual acuity and ocular dominance did not affect the group comparisons. Surgery on both eyes resulted in significantly better self-reported visual function and stereopsis than surgery on one eye.

Quality of life assessment for nuclear, cortical, posterior subcapsular patients before and after cataract surgery

PurposeThe impact of visual outcomes of cataract surgery can be measured using a questionnaire. The aim of our study was to evaluate how patient quality of life changes after cataract surgery and if there are differences between the responses of patients with nuclear, cortical, and posterior subcapsular cataracts, which has not been studied before. MethodWe studied 210 cataract patients who were divided into 3 cataract groups based on their cataract type: nuclear (n = 80), cortical (n = 70), and posterior subcapsular (PSC) (n = 60). The patients completed the Visual Function Index (VF-14) questionnaire before, 2 weeks and 1 month after bilateral cataract surgery. The results were analysed using one-way ANOVA (significance level 5 %) and were compared over time and between the cataract groups. ResultsBefore the cataract surgery, cortical cataract patients had the lowest questionnaire score compared to nuclear and posterior subcapsular cataract groups (p = 0.08). After cataract surgery, cortical cataract patients experienced the greatest improvement in near distance daily activities, while PSC cataract patients experienced the greatest improvement in far distance daily activities (p = 0.38). Before surgery, nuclear cataract patients had the highest questionnaire scores compared to the other cataract groups (p = 0.08). ConclusionAt the 1 month follow-up, there were no statistically significant differences in questionnaire scores between the cataract groups for any of the questions. Overall, cortical cataract patients showed a trend to experience the greatest subjective improvement in quality of life after cataract removal, followed by nuclear and posterior subcapsular patients.

Objective: To determine the visual outcomes of cataract surgery with foldable lens at tertiary care eye hospital SindhPakistan. Study design and setting: An observational cross-sectional study carried out at Ghulam Muhammad Maher Medical College (GMMMC) Sukkur from February 2020 to January 2022. Methodology: A Non-probability purposive sampling was used. Inclusion were all individuals attending eye OPD with complaint of cloudy vision and diagnosed with cataract. Patients suffering from corneal diseases, chronic anterior uveitis intraocular pressure &gt;22 mmHg, high ametropia and Diabetes Mellitus were excluded from the study. SPSS was used to analyze data. Results: Total of 153 patients were selected for this study. Age of the patients was from 40 to 72 years. 60% of patients were between 40-60 years age whereas 40% were above 60 years. Gender differences observed 73 (48%) female and 80(52%) male. On 1st postoperative day Best Corrected Visual acuity (BCVA) was 6/9 in 90 patients, 6/12 in 40 patients and 6/6 in 23 patients. After 1 week follow-up, BCVA was 6/6 in 100 patients, 6/9 in 33 patients and 6/12 in 20 patients. After 1 month, BCVA was recorded as 6/6 in 130 patients, 6/9 in 20 and 6/12 in 3 patients. Conclusion: Visual acuity outcome with foldable lens after Phacoemulsification was found excellent within one month. Implantation of foldable lens with phacoemulsification gives better results in terms of visual acuity.

Visual Outcomes of Cataract Surgery in Patients With Keratoconus Using Toric and Non-toric Lenses

To compare the accuracy and outcomes of different intraocular lens (IOL) power calculation formulas in eyes with keratoconus undergoing cataract surgery with toric and non-toric IOLs. This was a consecutive retrospective case series study including patients from the Cornea Service at the Department of Ophthalmology and Visual Sciences at the University of British Columbia, Vancouver, Canada, from 2000 to 2020. Keratoconus was diagnosed based on corneal topography and clinician opinion. Patients who underwent topography-guided photorefractive keratectomy, intracorneal ring segments implantation, or corneal transplant were excluded. The manifest spherical equivalent, prediction errors, and median absolute errors were calculated. Descriptive statistics were expressed as mean ± standard deviation. There were 160 eyes from 101 patients; 136 eyes received non-toric lenses and 24 eyes received toric lenses. Most patients had mild disease (< 48.00 diopters [D]) when stratified by steep keratometry values. Patients with severe disease (> 53.00 D) were significantly more hyperopic following surgery (P < .05). The Barrett Universal II (0.26 D, inter-quartile range [IQR] = 0.4), Holladay 2 (0.31, IQR = 1.2), and SRK/T (0.42, IQR = 0.86) formulas had the lowest median absolute error. The postoperative prediction error following toric lens insertion was not significantly different than following non-toric lens insertion, and the mean absolute astigmatism was significantly reduced with toric lenses. The Barrett Universal II, Holladay 2, and SRK/T were the most accurate IOL power calculation formulas in patients with keratoconus undergoing cataract surgery. Hyperopic surprise was increased in severe keratoconus. Toric IOLs may be considered in patients with mild keratoconus. [J Refract Surg. 2023;39(5):319-325.].

Complications and visual outcome of cataract surgery in pseudoexfoliation patients

Pseudoexfoliation syndrome is a multifactorial diffuse disease and is diagnosed clinically on slit lamp examination of the eye by the deposition of white, dandruff like material on different structures in anterior segment i:e corneal endothelium, iris, pupillary margin, anterior lens capsule, zonules and trabecular meshwork. The aim of study was to study demographic features, intraoperative and postoperative complications and the visual outcome of cataract surgery in pseudoexfoliation patients. 93 eyes of 93 patients with pseudoexfoliation posted for cataract surgery were included in the study. 79.56% patients were of more than 60 years of age group.43 patients were male and 50 patients were female. 44 patients had pseudoexfoliation syndrome in both eyes and 49 patients had either right eye or left eye involvement. Intraoperative problems encountered were poor pupillary dilatation, capsular bag prolapse, zonular dehiscence, posterior capsular rent, residual cortical matter and positive vitreous pressure. Postoperative complications reported were corneal edema, raised intraocular pressure, significant anterior chamber cell reaction, left cortical matter and exudative membrane. Best corrected visual acuity was more than 6/18 in 67 eyes, between 6/60-6/24 in 16 eyes, and less than 6/60 in 10 eyes. At 1 month, best corrected visual acuity was more than 6/18 in 92 eyes. Cataract surgery in pseudoexfoliation patients is associated with high risk of complications. Use of iris hooks and capsule tension rings where required during the surgery can decrease the intraoperative complications and thus will give better visual outcome.

A Study of Visual and Anatomical Outcomes of Cataract Surgery with Intraoperative Complications in a Teaching Institute

Introduction: To study the incidence, visual outcomes, andanterior segment anatomical outcomes of intraoperativecomplications of cataract surgery.Materials and Methods: This is a prospective observationalhospital-based study conducted in the department ofOphthalmology SRMS IMS, Bareilly, Uttar Pradesh. Inthis study, 70 patients were studied for 1.5 yrs from 1st ofNovember 2019 to 13th of April 2021. All these patients withintraoperative complications were evaluated preoperatively andpost-operatively for vision and anterior segment anatomicaloutcomes.Results: In this study, the commonest intraoperativecomplication was Injury to Iris/ Iridodialysis (52.9%). Basedon pre-operative vision, the patients had 5/60 and 6/36 visionwith 30.0%, each followed by 6/24 (14.3%) and 3/60 (12.9%).Corneal hazy/edema was reduced to 10.0% at one-monthfollow-up from 52.9% on post-operative day one. Also, DMfolds were reduced to 11.4% from 75.7% at day one.Conclusions: In this study, visual outcome of the cataractsurgery was much better, and there is a significant progressionin the visual acuity. Routine monitoring of the visual outcomeof the cataract surgery at each hospital would go in long-wayto enhance both the quantity and quality of the surgery andthus decrease the substantial amount of burden of blindnesson our country.

Outcome of Cataract Surgery in Patients With Retinitis Pigmentosa

To assess the visual outcome of cataract surgery in patients with retinitis pigmentosa (RP). Retrospective, noncomparative clinical study. Preoperative, intraoperative, and postoperative data of patients with RP who were undergoing cataract surgery were collected from several expertise centers across Europe. In total, 295 eyes of 225 patients were included in the study. The mean age at surgery of the first eye was 56.1 ± 17.9 years. Following surgery, best-corrected visual acuity (BCVA) improved significantly from 1.03 to 0.81 logMAR (ie, 20/214 to 20/129 Snellen) in the first treated eye (-0.22 logMAR; 95% CI=-0.31 to -0.13; P < .001) and from 0.80 to 0.56 logMAR (ie, 20/126 to 20/73 Snellen) in the second treated eye (-0.24 logMAR; 95% CI=-0.32 to -0.15; P < .001). Marked BCVA improvements (postoperative change in BCVA of ≥0.3 logMAR) were observed in 87 of 226 patients (39%). Greater odds for marked visual improvements were observed in patients with moderate visual impairment or worse. The most common complications were zonular dialysis (n=15; 5%) and (exacerbation of) cystoid macular edema (n=14; 5%), respectively. Postoperative posterior capsular opacifications were present in 111 of 295 eyes (38%). Significant improvements in BCVA are observed in most patients with RP following cataract surgery. Baseline BCVA is a predictor of visual outcome. Preoperative evaluation should include the assessment of potential zonular insufficiency and the presence of CME, as they are relatively common and may increase the risk of complications.

Visual Outcome after Cataract Surgery in Phacolytic Glaucoma

A prospective study was conducted between March 2021 and February 2022 in the National Institute of Ophthalmology &amp; Hospital, Dhaka, Bangladesh involving 30 patients who underwent cataract surgery for phacolytic glaucoma. The aim of this study was to see the postoperative visual outcome of cataract surgery in patients with phacolytic glaucoma. Visual acuity and development of any postoperative complications were recorded. The mean age of the patients was 60.7 years. Female to male ratio was 1.3:1. Most of the patients (67%) presented after 1 week of symptoms. On the first visit, mean preoperative intraocular pressure (IOP) was 37.5 mm of Hg. Following surgery, 93.33% had an intraocular pressure less than 21 mm Hg at discharge. Visual acuity (VA) as perception of light (PL) was found doubtful in 2 (6.67%), while PL was positive in 17 (56.66%) and HM &lt;3/60 was in 11 (36.66%) preoperatively. At discharge, 73.33% achieved VA 6/24 or better, 5 (16.67%) had less than 6/24 and 3 (10%) less than 3/60. Cataract surgery is effective to restore visual acuity and lowering the intraocular pressure (IOP) in patients with phacolytic glaucoma.&#x0D; CBMJ 2022 July: vol. 11 no. 02 P: 120-124

Intraoperative complications and visual outcomes of cataract surgery in patients with retinal vein occlusion: multicenter database study.

To compare the visual outcomes and the rate of intraoperative complications in eyes with and without retinal vein occlusion (RVO) after phacoemulsification over a period of 15 years in a real-world clinical setting. 8 independent U.K. National Health Service ophthalmology departments. Retrospective, multicenter cohort study. Eyes were classified based on the presence or absence of RVO. For analyzing visual acuity (VA) and the incidence of postoperative cystoid macular edema, eyes with any copathology, combined ocular surgical procedures, and intraoperative complications, or of diabetic patients were excluded. Of 178 856 eyes, 1796 eyes with RVO preoperatively and 177 060 eyes without RVO were allocated to the RVO group and the reference group, respectively. Cataract surgery in eyes with RVO was associated with an improvement in the mean VA of 0.35 logMAR (3 to 4 Snellen lines), and a substantial gain (≥0.30 logMAR units [3 Snellen lines]) was achieved in 55.10% of eyes at 4 to 12 weeks postoperatively. The mean postoperative VA was worse in eyes with RVO compared with that in eyes without RVO at 4 to 12 weeks (logMAR 0.40 vs 0.12 [20/50 vs 20/25]; P < .0001). The proportion of eyes achieving a visual gain of ≥ 0.3 logMAR (3 Snellen lines) was also lower in eyes with RVO (55.10% vs 64.55%; P = .0076). There was no statistically significant difference in posterior capsule rupture rates between the 2 groups (1.73% vs 1.72%; P = .9741). Although postoperative vision improved significantly in eyes with RVO after cataract surgery, this improvement was worse than that achieved by eyes without RVO.

Visual outcome of cataract surgery from a free outreach camp among rural areas of Southern-Kaduna, Nigeria

Objectives: The objectives of the study were to assess the visual outcome of those who underwent free cataract surgery in southern senatorial zone of Kaduna State between September and November 2018, and to identify the causes of poor visual outcome (Visual acuity [VA] &lt;6/60 Post op), suggest ways of improving it and comparing findings of this study with other studies. Materials and Methods: An observational study of consecutive patients with dense cataracts and VA &gt;6/60 who underwent manual small incision cataract surgery (MSICS) with intraocular lens implant (IOL). All patients had posterior chamber intraocular lens (PCIOL) implant after cataract extraction except 6 who had anterior chamber intraocular lens. A total of 116 eyes of 116 patients who met the inclusion criteria were recruited for the study but only 109 were followed up for 8 weeks postoperatively. Their VA pre-operative was noted. Postoperatively, 1st day, 1,and 8 weeks presenting VA were noted while best corrected VA (BCVA) at 1 week and 8 weeks were also noted. Information collected was analyzed with Statistical Package for the Social Sciences version 19. A 95% significant confidence interval was used, that is, P &lt; 0.05. Results: Age range of patients in this study was 40–80 years with a male to female ratio of 1.02:1. All patients presented pre-operatively with poor vision (VA &gt;6/60) but after surgery 27.3%, 42.2%, and 56.6% of patients had good vision (VA 6/6–6/18) on 1st day, 1 week, and 8 weeks post-operatively, respectively, with a BCVA in 75.6% of study population. Complications such as corneal edema, posterior capsule rent, iris tear, cortical remnants, and uncorrected residual refractive errors contributed to poor visual outcome (VA &lt;6/60) 8 weeks after surgery. Conclusion: MSICS was effective in restoring visual loss from cataract. Even though the WHO standard was not achieved in this study, provision of required technology for pre-operative preparation and post-operative follow-up along with improvement in surgical techniques will improve visual outcome after cataract surgery.

Outcome of Cataract Surgery at Secondary Eye Care Facility in Karachi

Purpose: To find out visual outcome of cataract surgery at secondary eye care hospital in Karachi, Pakistan. Study Design: Surgical audit. Place and Duration of study: Al-Baseer Eye Hospital, Karachi from January 2019 to January 2021. Methods: A total of 1540 cataract surgeries were performed. Patients referred from distant eye camps (outside of city limits) were not included. Data collection was done using hospital medical records on patient’s age, sex, pre-operative best-corrected visual acuity (BCVA), surgical complications, visual acuity(VA) at 1st post-operative day, 1, 3 and 4 – 16 post-operative weeks, BCVA at 4 – 16 post-operative weeks and causes of poor visual outcome (BCVA worse than 6/60) at 4 – 16 post–operative weeks. For data analysis, IBM SPSS Statistics 23 was used. Results: Out of 1540 cataract surgeries, 81% (1248) cases underwent phacoemulsification with intraocular lens implantation. Mean age at the time of surgery was 56.24 ± 11.45 years. Males were 54.9% (845) while 45.1% (695) were females. Rate of intraoperative complications was 0.9% (14 cases). Posterior capsule rupture occurred in 0.8% (13 cases), and zonular disinsertion in 0.1% (1 case). At 4 – 16 weeks post-operatively, follow–up rate was 53.8% (828 patients); and the percentages of patients with good, borderline and poor BCVA were 94.7% (784 cases), 2.3% (19 cases), and 3.0% (25 cases) respectively. Conclusion: Good visual outcome can be obtained after cataract surgery at a secondary eye hospital, provided the surgeons and operating room team are trained, well equipped and follow aseptic measures. Key Words: Phacoemulsification, Cataract, Posterior capsule, Blindness.

A Prospective Study on Visual Outcomes of Cataract Surgery after Phacoemulsification with Foldable vs Non Foldable Intraocular Lenses

A Prospective Study on Visual Outcomes of Cataract Surgery after Phacoemulsification with Foldable vs Non Foldable Intraocular Lenses
