Monocular Electrical Cataract: A Case Report

Introduction : An electric shock is experienced when an electric current passes through a part of the body from an entry point to an exit point. Cataract is frequently described as a complication of electrical injury and it is usually bilateral. We report a rare case of high voltage electric injury in young male patient resulting in monocular cataract.
 Case Illustration : A 23 years old man was presented with a diminution of vision one year after sustaining an overhead high voltage power transmission wire that stung his head. The visual acuity of the right eye was hand movement dan 1.0 in the left eye. On slit-lamp examination, opacities were presented in the lens of the right eye and a clear lens in the left eye. Being diagnosed as having monocular cataract, the patient was then performed phacoemulsification on his right eye (April 12th 2023). The pupil shrank until 5 mm during the surgery but foldable IOL was successfully inserted in the capsule. The right eye vision was improved to 0.5 one day after surgery.
 Discussion : The consequences of high-voltage electric burns are complex. Electrical shock can cause protein coagulation and cataract formation. Lens manifestations are more likely when the transmission of current involves the patient’s head. Proper management of electrical cataracts will result in good visual rehabilitation if the eye does not suffer additional damage as in this case.
 Conclusion : Secondary cataract formation due to electric injury may occur, therefore routine examinations with the ophthalmologist are needed after the electrical trauma. The incidence of monocular cataracts after the electric injury is rare.

Restoring vision after cat bite: a case report on successful diagnostic and therapeutic regimen for Capnocytophaga endophthalmitis

BackgroundCapnocytophaga is a bacterium frequently found in the oral flora of dogs and cats (e.g. Capnocytophaga canimorsus) and humans (e.g. Capnocytophaga gingivalis). Among Capnocytophaga related ocular infections, fulminant endophthalmitis is a rare but sight-threatening clinical manifestation.Case presentationA 35-year-old previously healthy patient presented after a cat bite into the left upper and lower eyelid and nasal part of the conjunctiva of the left eye. At initial consultation, the corrected visual acuity was 0.8 in decimal scale and a detailed clinical examination revealed no evidence of ocular penetration. However, daily follow-up examinations under local therapy revealed a progressive intraocular inflammation, therefore the decision was made to perform a diagnostic vitrectomy with intravitreal and systemic antibiotic treatment. Capnocytophaga felis was detected as the cause of endophthalmitis and the initiated treatment resulted in quick morphological and functional recovery of the left eye. After surgery of secondary cataract, visual acuity improved from hand motion preoperatively to 1.0 postoperatively.ConclusionsEarly recognition as well as prompt and effective treatment of animal bite associated endophthalmitis is essential for good visual recovery and functional outcome. Furthermore, this case highlights the importance of daily follow-up examinations, even in the absence of signs of ocular penetration and intraocular inflammation, to enable prompt and effective treatment initiation. Given the negative results in bacterial culture, we additionally emphasize the value of sequencing-based microbiological diagnostics in unclear cases.

Secondary cataract in patients after traditional phacoemulsification in comparison with femtolaser extraction

BACKGROUND: Secondary cataract is a frequent complication of the postoperative period of cataract surgery.
 AIM: To evaluate the timing of secondary cataract formation in pseudophakic eyes after cataract extraction phacoemulsification, carried out as traditional phacoemulsification in comparison with femtolaser cataract surgery.
 MATERIALS AND METHODS: We conducted a retrospective study of patients who underwent YAG laser posterior capsulotomy (98 people, 108 eyes). All patients were divided into two groups. First group (54 people, 58 eyes) consisted of patients in whom secondary cataract occurred after traditional phacoemulsification. In the second group (44 people, 50 eyes) secondary cataract occurred after femtolaser-assisted cataract surgery. All patients were implanted with a monofocal intraocular lens MIOL-2.
 RESULTS: The data analysis revealed that the period of secondary cataract formation in the first group was 2.83 ± 1.25 years, in the second group 3.75 ± 1.0 years.
 CONCLUSIONS: The analysis showed that the secondary cataract after traditional phacoemulsification occurs earlier by an average of 1 year than after femtolaser-assisted cataract surgery.

Comparative assessment of the state of the cornea after YAG-laser interventions on anterior segment structures

This study evaluates the condition of the cornea after laser discission (LD) of secondary cataracts (SC) and laser iridectomy (LI) using corneal confocal microscopy (CCM). Group 1 included patients with the diagnosis "Pseudophakia, secondary cataract", they underwent LD of SC. Patients of group 1 were divided into 2 subgroups depending on the initial state of the cornea: group 1A included patients with unaltered corneas; group 1B - with changes in the corneas. Group 2 included patients diagnosed with angle-closure glaucoma (ACG) or suspected ACG, they underwent LI. CCM was performed on the Heidelberg HRT-III system. Laser treatment was performed using the Nd:YAG-laser LPULSA SYL-9000, λ=1.064 µm. Immediately after treatment, subgroup 1A exhibited singular hyperreflective deposits and negligible endothelial cell loss (ECL). After 1 month, CMM findings revealed no changes in this subgroup. In subgroup 1B, a post-LD reduction in endothelial cell density led to increased polymegathism, decreased pleomorphism, heightened endothelial cell nucleus reflectivity, and moderate hyperreflective deposits after 1 month. In the second group, significant hyperreflective deposits of various sizes, increased nucleus reflectivity, and notable endothelial cell density reduction were observed immediately and 1 month after LI. The results of this study show that the possibility of developing corneal complications after photo destructive laser interventions is to a certain extent related to the initial state of the cornea. The risk of developing corneal damage increases with decreasing distance between the cornea and the irradiated structure. An increase in the level of laser radiation energy and its total values also contributes to damage to the cornea, which is possible with dense secondary cataracts and thick irises.

Результаты имплантации монофокальной интраокулярной линзы Clareon с автоматизированной системой доставки AutonoMe (один год наблюдений)

Material and methods. The short- and long-term results of phacoemulsification with implantation of 700 Clareon intraocular lenses (IOL) preloaded into disposable pneumatic AutonoMe delivery systems were studied. The optical power of the IOL was calculated using the Verion system using modern formulas for emmetropia. Functional and refractive results, surgical and postoperative complications were assessed. Results. Of the 700 Clareon IOL implantations performed, 693 (99.0%) were without complications; complications occurred in 7 (1.0%) eyes. By 12 months of observation, BCDVA and UCDVA increased from 0.15±0.03 to 0.65±0.09 and from 0.31±0.04 to 0.76±0.12 (p<0.05), respectively. Refraction of the target was achieved in 90% of patients. The loss of endothelial cells from the baseline level was 4.8%. In all patients, the optical part of the IOL remained stably transparent, no glistening phenomena were observed in any case; the haptic component of the IOL provided a stable correct central position of the IOL in the capsule bag. Secondary cataract developed in 22/605 (3.6%) eyes, which required dissection in 19/605 (3.1%) eyes. Conclusion. The new monofocal intraocular lens Clareon is high-tech and can be widely used in clinical practice. The new automated pneumatic delivery system AutonoMe is efficient and safe. Key words: phacoemulsification, Clareon, automatic IOL delivery system, glistening, secondary cataract

Cataracts after Ophthalmic andNonophthalmic Trauma Exposure inService Members, U.S. Armed Forces.

IntroductionWe aimed to identify injury-related risk factors for secondary cataract incidence after eye and brain injury and polytrauma. We also examined the effect of direct and indirect eye injury management on cataract diagnosis and treatment. Prevention or mitigation strategies require knowledge of the causes and types of combat injuries, which will enable more appropriate targeting of resources toward prevention and more efficient management of such injuries. Data were gathered from the Military Health System using the Military Health System Management and Analysis Reporting Tool (M2) between 2017 and 2021 from inpatient and outpatient Service Members (SMs) (active duty and National Guard). The date of the first cataract diagnosis was tracked to estimate the annual incidence rate, and it was longitudinally linked to any prior diagnosis of ocular trauma (OT), traumatic brain injury (TBI), or polytrauma to calculate the relative risk. International Classification of Disease codes, 10th Revision, were used to identify those diagnosed with cataracts, TBI, and polytrauma. Defense and Veterans Eye Injury and Vision Registry data were used to examine SMs who sustained ocular injuries from 2003-2020 and who may have had cataract surgery following a cataract diagnosis. The relative risk of traumatic cataract formation from OT, TBI, and polytrauma are 5.71 (95% CI, 5.05-6.42), 2.32 (95% CI, 2.03-2.63), and 8.95 (95% CI, 6.23-12.38), respectively. Traumatic cataracts in SMs more commonly result from open-globe injuries (70%) than closed-globe injuries (30%). By specific sub-injury type, traumatic cataracts occur most frequently from intraocular foreign bodies (22%). More than 400 patients in the cohort suffered from TBI and traumatic cataracts, more than 300 from OT and cataracts, and more than 20 from polytrauma and cataracts. The battlefield is the riskiest environment for trauma exposure, with 62% of OT occurring in combat. There was a statistically significant difference between the mean visual acuity value before cataract surgery (M = 1.17, SD = 0.72) and the mean visual acuity value after cataract surgery (M = 0.44, SD = 0.66, P < .001). Traumatic cataracts often occur in SMs who sustain ocular injuries. New to the literature is that relationships exist between traumatic cataract formation and nonglobe trauma, specifically TBI and polytrauma. Ocular injury calls for an ophthalmic examination. A low threshold should exist for routine ocular exam consultation in the setting of TBI and polytrauma. Separately, polytrauma patients should undergo a review of systems questions, particularly questions about the ocular and visual pathways. A positive response to screening warrants further investigation of possible ocular pathology, including traumatic cataract formation. Cataract surgery is an effective treatment in improving the vision of SMs who suffer from traumatic cataracts. Constant effort must be made to limit occurrences of occupation-related traumatic cataracts.

Small incision lenticule extraction (SMILE) surgery as an effective strategy to treat Megalocornea: A case report

Megalocornea is a developmental defect in which the entire anterior segment is enlarged bilaterally. Megalocornea is associated with Marfan syndrome and other ocular and systemic congenital defects. One may suppose that in situations of megalocornea, there may be abnormal collagen production, abnormal collagen tissue/cross-linking, a risk of corneal ectasia, and the presence of secondary glaucoma or cataracts, which may serve as the factors for not considering refractory surgeries. We report a case of megalocornea that was successfully treated with small incision lenticule extraction surgery. The patient noticed considerable improvement and no further complications were observed during the follow-up.

Выяснение взаимосвязи между формированием регматогенной отслойки сетчатки и проведенной ИАГ-дисцизией вторичной катаракты

Aim. Retrospective analysis of case histories of patients operated at Khabarovsk branch of S. N. Fedorov “NMRC “MNTK “Eye microsurgery” for rhegmatogenous retinal detachment in 2013–2016, who had previously undergone Nd:YAG laser posterior capsulotomy. Methods. Method of continuous sampling was used. During the study period, 19 cases of retinal detachment were identified in patients who had previously undergone Nd:YAG laser posterior capsulotomy. There were 5 women (26 %), 14 men (74 %). Mean age of patients was 63±0.5 years (from 59 to 65 years). Probable causes of retinal detachment development were analyzed. Results. It was revealed that in the early postoperative period development of retinal detachment is caused by formation of retinal horseshoe tears and more often in patients with hyperopia, emmetropia and myopia of low degree. In the late postoperative period, development of retinal detachment is associated with progression of predictively dangerous forms of peripheral retinal degeneration and more often in patients with high myopia. Conclusion. Thorough examination of periphery of the retina in early and late postoperative periods and carrying out barreer laser coagulation of the retina are measures of prevention of retinal detachment after Nd:YAG laser posterior capsulotomy. Key words: secondary cataract; Nd:YAG laser posterior capsulotomy; retinal detachment.

Complicated uveitis in a spondyloarthritis patient: a case report

Background: Ophthalmic manifestations, like uveitis, might be one of the complications of spondyloarthritis. Many individuals experiencing acute uveitis are unaware that spondyloarthritis has already been present. The late diagnosis and treatment of uveitis can result in permanent vision impairment. This case report presents the diagnosis and management by a rheumatologist and ophthalmologist of a spondyloarthritis patient with complicated uveitis. Case: On October 27, 2021, a 42-year-old male patient came to the rheumatology outpatient clinic of Dr. Soetomo General Hospital, Surabaya, Indonesia with intermittent low back pain for the past fourteen years, which worsened in the last eight months. The pain was accompanied by morning stiffness for about an hour after getting-up every day, gradually relieved by stretching. The lumbosacral x-ray revealed bilateral sacroiliitis. The patient also came to the ophthalmology outpatient clinic with sudden left eye pain and gradually blurred vision for the past two years. He was diagnosed with spondyloarthritis with bilateral uveitis, secondary glaucoma, and secondary cataract on both eyes. He was given methotrexate, sulfasalazine, sodium diclofenac, topical timolol 0.5%, topical atropine, acetazolamide, and methylprednisolone. The low back pain and impaired vision were improved after three months of treatment. Conclusion: Uveitis should be suspected as a relatively common complication of spondyloarthritis. Early diagnosis and treatment of this uveitis might prevent permanent damage.

Change in macular thickness after uncomplicated phacoemulsification surgery using optical coherence tomography in a tertiary care hospital.

To determine the change in macular thickness after uncomplicated phacoemulsification surgery using optical coherence tomography in a tertiary care hospital. This study was conducted at Department of Ophthalmology Jinnah Postgraduate Medical Centre Karachi, for 6 months from 10th Dec 2019 to 10th June 2020. Sample size calculation of 52 eyes was done by using open epi software. Patients who fulfilled the inclusion criteria that is age ranging from 50 to 75 years, either gender with senile cataract having no preexisting ocular or systemic disease and those giving consent were included in this study. Patients with any comorbidity ocular trauma, having pre-existing ocular diseases such as active ocular infection, glaucoma, maculopathy or retinopathy were excluded from study. Patients with secondary cataract also excluded from study. After complete history, all patients underwent detailed ophthalmologic examination and Pre-surgery macular thickness recorded by using swept source OCT (DRI-OCT-2 Triton; Topcon). Surgery was performed and intraocular lens was implanted in all cases. Post procedure Macular thickness was measured using swept source OCT at 1st postoperative day, 1st month and 6th month after surgery. The mean age of patients was 62.06 ± 5.1 years. Total of 52 eyes diagnosed with senile cataract were included in this study. There were 30 (57.7%) males and 22(42.3%) females. The mean preoperative central foveal thickness was 201.3±24.8μm. The postoperative central foveal thickness was 200.3±25.2μm (153-265μm) at day 1st of surgery, 224.1 ± 53.8 μm (151-458 μm) at 1st month and 212.4±28.3μm (167-255μm) 6th month after surgery. The mean preoperative BCVA was 0.70 ± 0.43 (0.1-1.7) logMAR. The postoperative mean BCVA was 0.26 ± 0.42 (0.00-3.10) logMAR at 1st day, 0.07± 0.10 (0.000.7) logMAR at 1st month and 0.05 ± 0.10 (0.00-0.3) logMAR at 6th month. In our study we found an increase in macular thickness but there was no loss of BCVA from changes of macular thickness after surgery and the mean BCVA increased progressively in postoperative period.

ErbBs in Lens Cell Fibrosis and Secondary Cataract.

TGFβ-induced epithelial-to-myofibroblast transition (EMyT) of lens cells has been linked to the most common vision-disrupting complication of cataract surgery-namely, posterior capsule opacification (PCO; secondary cataract). Although inhibitors of the ErbB family of receptor tyrosine kinases have been shown to block some PCO-associated processes in model systems, our knowledge of ErbB signaling in the lens is very limited. Here, we investigate the expression of ErbBs and their ligands in primary cultures of chick lens epithelial cells (dissociated cell-derived monolayer cultures [DCDMLs]) and how TGFβ affects ErbB function. DCDMLs were analyzed by immunofluorescence microscopy and Western blotting under basal and profibrotic conditions. Small-molecule ErbB kinase blockers, including the human therapeutic lapatinib, selectively inhibit TGFβ-induced EMyT of DCDMLs. Lens cells constitutively express ErbB1 (EGFR), ErbB2, and ErbB4 protein on the plasma membrane and release into the medium ErbB-activating ligand. Culturing DCDMLs with TGFβ increases soluble bioactive ErbB ligand and markedly alters ErbBs, reducing total and cell surface ErbB2 and ErbB4 while increasing ErbB1 expression and homodimer formation. Similar, TGFβ-dependent changes in relative ErbB expression are induced when lens cells are exposed to the profibrotic substrate fibronectin. A single, 1-hour treatment with lapatinib inhibits EMyT in DCDMLs assessed 6 days later. Short-term exposure to lower doses of lapatinib is also capable of eliciting a durable response when combined with suboptimal levels of a mechanistically distinct multikinase inhibitor. Our findings support ErbB1 as a therapeutic target for fibrotic PCO, which could be leveraged to pharmaceutically preserve the vision of millions of patients with cataracts.

Долгосрочные результаты имплантации новой недифракционной ИОЛ с расширенной глубиной фокуса

Purpose. To evaluate long-term results of AcrySof IQ Vivity non-diffractive extended-focus intraocular lens (IOL) implantation. Material and methods. 20 patients (20 eyes) underwent phacoemulsification and implanted non-diffractive IOL with expanded depth of focus. The mean age of the patients was 64.4 years (54 to 70 years). All patients were followed up for one year. Long-term results were analyzed. The postoperative period was smooth. Two patients developed secondary cataract 6 months later and IAG-laser discectomy of the posterior capsule was performed. Results. In 12 months after surgery, the uncorrected visual acuity (UCVA) in the distance was — 0.88 ± 0.06, at the middle distance — 0.77 ± 0.02, in the vicinity — 0.60 ± 0.05. Best corrected visual acuity in the distance — 0.93 ± 0.04, in the middle distance — 0.81 ± 0.07, in the vicinity — 0.65 ± 0.01. One patient (5 %) had periodic light scattering circles (halo) and one patient (5 %) — had glare. There were no difficulties with driving in any of the patients. Conclusions. The AcrySof IQ Vivity IOL will provide improved visual acuity at all distances. Some patients will need to use additional spectacle correction, for near distance. 85 % patients rated the results as «excellent», 15 % — «good».

Hydroxychloroquine is neutral on incidental cataracts in patients with rheumatoid arthritis

To study whether hydroxychloroquine (HCQ) therapy increases the risks of cataracts in patients with rheumatoid arthritis (RA). In this retrospective cohort study, 2821 treatment-naive RA patients, collected from the Longitudinal Health Insurance Database, were enrolled from 2000 to 2012 and followed up monthly until secondary cataracts were detected but no later than Dec 31, 2013. All participants were split into two groups according to the usage of HCQ in one year: the HCQ group (465 patients), with a usage duration higher than 90 days, and the non-HCQ group (465 patients), with a usage duration less than 30 days. The HCQ and non-HCQ groups were age-, sex-, complication- and drug combination-matched. There was no significant difference in survival rate between the two groups (p > 0.05). A multivariate logistic regression model was applied. Of all participants, 173 were diagnosed with secondary cataracts in both the HCQ and non-HCQ groups, with 28.8/1000 and 36.5/1000 person-years, respectively. After adjustments for other predictors, patients in the HCQ group had no increased (or decreased/equal) hazard of secondary cataract (hazard ratio (HR): 1.17; confidence interval (CI): 0.86–1.59; p > 0.05). HR analysis of HCQ usage duration, age, sex and corticosteroids showed that the CI of the adjusted HR was not statistically significant. This study showed that HCQ usage was not associated with the risk of cataracts in RA patients.

Comparison of Frequency of Pseudo-Exfoliation Syndrome in Patients Undergoing Cataract Surgery in Different Regional Hospitals of Pakistan

Objective: To compare the frequency of Pseudo-Exfoliation Syndrome (PXS) in patients undergoing cataract surgery in different regional hospitals in Pakistan.&#x0D; Study Design: Cross-sectional study.&#x0D; Place and Duration of Study: Three Tertiary Care Hospitals of Karachi, Rawalakot and Skardu Pakistan, from Sep 2017 to May 2020.&#x0D; Methodology: Patients aged 45 years and more undergoing age-related cataract surgery were evaluated for Pseudo-Exfoliation Syndrome. Initially, each patient underwent a complete outpatient ophthalmological workup. Demographic details like age and gender were noted. All the patients were screened for hypertension and diabetes mellitus. In addition, patients were screened for pseudo-exfoliation syndrome. Congenital, developmental, secondary and traumatic cataracts were excluded.&#x0D; Results: A total of 1882 patients were included in the study. Pseudo-exfoliation was carried out in 249(13.23%) patients. In Hospital-A, 23(3.23%); in Hospital-B, 145(14.92%) and Hospital-C, 81(40.70%) of the patients had pseudo-exfoliation. The frequency of pseudo-exfoliation syndrome was significantly more in Hospital-C and then in Hospital-B and least in HospitalA (p&lt;0.01).&#x0D; Conclusion: Pseudo-exfoliation syndrome was significantly more common in Skardu and then in Rawalakot and least in Malir, which in the same order have more latitude away from the equator, have less average annual temperature and are situated at higher altitudes.

Primary Posterior Continuous Circular Capsulorhexis without the Use of Ophthalmic Viscosurgical Device.

Performing primary posterior capsulorhexis (PPCCC) during cataract surgery is an effective prevention of secondary cataracts. It is important not to damage the anterior vitreous membrane to minimize the possible complications and adverse side effects of this step of the surgery. Most authors use a viscoelastic material to protect the anterior vitreous membrane, injected into the space between the posterior lens capsule and the vitreous membrane through a small hole in the posterior capsule. The creation of posterior capsulorhexis using 25G forceps under an implanted intraocular lens while continuously filling the anterior chamber with irrigation fluid from an irrigation cannula, without the use of a viscoelastic material is, in our opinion, a safe, fast and cheap technique of PPCCC. This technique could theoretically lead to a lower incidence of postoperative complications such as higher postoperative intraocular pressure or anterior segment inflammatory response.

Presence of cataract in patients treated for retinoblastoma at the national institute of pediatrics in Mexico (2011–2021)

The goal of this study is to describe the presence of secondary cataract in patients with retinoblastoma treated at the National Institute of Pediatrics of Mexico (INP) over the past 10 years. This was a single center observational, retrospective and descriptive study. We included all eyes diagnosed with retinoblastoma and cataract between June 2011 and June 2021. In total, 833 records of patients diagnosed with Retinoblastoma at the National Institute of Pediatrics during the period between June 2011 and June 2021 were reviewed. Out of all of them, only 14 developed cataract (1.6%). The median age at retinoblastoma diagnosis was 10.5 months (Rank: 6-13 months), and the median age at cataract diagnosis was 51.5 months (Rank: 25-73 months). The majority (13, 92.9%) of the patients had bilateral involvement. 42% of the eyes were Stage D according to the international classification of retinoblastoma. Cryotherapy was applied in 57.1%, intravitreal chemotherapy in 85.7%, radiation therapy in 42.6%, and only 7.1% of cases were treated with intra-arterial chemotherapy. The presence of cataract in patients with retinoblastoma is a rare but important entity impacting the development of vision in children and detection of intraocular tumors. These probably occur late as a result of the multiple treatments to which the children have been subjected, without being able to determine in this study which is the risk factor most associated with the development of this pathology.

Primary versus secondary intraocular lens implantation following removal of congenital/de al of congenital/developmental catar elopmental cataracts: outcomes after acts: outcomes after at least 4 years.

The aim of this study is to evaluate the long-term outcomes of primary and secondary intraocular lens (IOL) implantation following removal of congenital/developmental cataracts. One hundred and forty-four patients aged under 16 years who were followed up between 2003 and 2021 were analyzed retrospectively. The long-term results of children who underwent surgery before 2 years of age for congenital or developmental cataracts and underwent secondary IOL implantation after 2 years of age and those who underwent cataract surgery with primary IOL implantation after 2 years of age were compared. Patients with traumatic, secondary cataracts and cataracts due to ocular anomalies were not included in the study. We evaluated 64 patients (mean age 9.5 ± 4.5 years) with secondary IOL implantation and 80 patients (mean age 12.8 ± 4.1 years) with primary IOL implantation in the study. Distance and near best-corrected visual acuities were significantly better in the primary IOL group than the secondary IOL group (p < 0.001). Incidence of strabismus after primary IOL surgery was significantly lower and presence of binocular vision was more often than the secondary IOL group (p = 0.002). There was no significant difference between the two groups in terms of refraction and myopic shift (p = 0.242, p = 0.172, respectively). Mean refractive changes were significant in unilateral cases of secondary IOL group and primary IOL group (p = 0.013, p = 0.049, respectively) and myopic shift was also greater in both groups of unilateral cases than the fellow eyes (p = 0.023, p = 0.012, respectively). Visual outcomes and binocular vision were better, and the incidence of strabismus was also much less in the primary IOL group.

Cataract Surgery Results of New Lens Implantation “Synthesis”

Purpose. Analysis of the cataract surgery visual outcomes and advantages of intraocular lens Synthesis SIPY.Material and methods. We have operated 43 eyes with cataract (38 patients) using Synthesis SIPY lens. Non-corrected visual acuity was 0.13 ± 0.08, best corrected visual acuity (BCVA) was 0.36 ± 0.1.Results. Following 7 months, secondary cataract was not detected in any patient, what explain the actuality of square edge optical part on 360° of perimeter. The lens is inserted in cartridge in factory sterile conditions which exclude the contact between lens and environment, reduce the risk of incorrect inserting of the lens in cartridge following pinching by the cartridge flaps and, subsequently, the haptic tearing off. This complex “lens-cartridge” excludes the damage of haptics and optic parts, which can occur in using other IOLs during the removal of the lens from the vial and placing it in the groove of the cartridge. Position of cartridge in injector centralizes the cartridge tunnel for the Accuject Pro injector plunger, thereby reducing the risk of pinching the rubber tip of the IOL haptic plunger during implantation. The diameter of the cartridge tip allows the IOL to be implanted through a 1.6 mm tunnel. The uncorrected visual acuity after surgery was 0.6 ± 0.28. The best corrected visual acuity was 0.78 ± 0.24.Conclusions. The Synthesis SIPY lens has a number of advantages: factory installation of the lens into the cartridge and compatibility of the cartridge with the Accuject Pro injector prevent damage to the IOL; Implantation of the Synthesis SIPY lens is possible through the 1.6 mm corneal tunnel; high diopter ranges from -10.0D to + 40.0D allows for maximum visual results.

The prevalence of cataract by vision screening in a Belgium nursing home residents in 2021

AbstractPurpose: With an ageing population that continues to grow, and 13.6% of the population aged 65 or over receive long term formal care, 8.5% residing in Elderly homes in Belgium. We aim to map prevalence of visual impairement, and blindness caused by cataract, and refractive errors in a nursing home in Belgium.Methods: Between 07/04/2021 and 09/05/2021, 170 residents of a nursing home in Flanders were examined. Detailed medical and family history, complete ophthalmological examination including visual acuity, slit lamp examination of the anterior segment of the eye, measurement of intraocular pressure, eye fundoscopy and OCT (not in all of them) was performed.Results: Visual acuity of 146 residents (88%) of 170 residents of elderly home, 111 (65.29%) women and 59 (34.70%) men was determined. Mean age of the residents was 81.54 (±10.89) years. Of all participants, 8 (4.70%) were blind and 63 (37.06%) were moderately or severely visually impaired. In 24 residents (14.12%), visual acuity could not be determined. The prevalence of cataracts, secondary cataract and previous cataract surgery in the 170 residents was: respectively 102(60.00%), 27 (15.88%) and 36 (21.80%).In the 102 residents with cataracts, secondary cataracts and operated of cataract were respectively 90 (52.94%), 15 (%) and 32 (%) bilateral and 12 (%), 12 (7.06%) and 4 (%) unilateral.Conclusions: Many elderlies in these nursing home have poor access to Eyecare, because of their immobility. This might lead to vision impairment and blindness, affecting their social life and quality of life. An ophthalmological examination and treatment can be useful to avoid progressive visual impairment and eventually blindness.Author Javdani Sanatgar Moghaddam Zahra, MD, (Presenting Author) irisjavdani@yahoo.frOther Authors.Prof Robert Kuijpers robert.kuijpers@uzbrussel.beDr Frank Goes frank@goes.be
