One Year

A 37-year-old Japanese man had his right eye hit by a fist. His right eye developed hypotony maculopathy and secondary cataract, and his visual acuity decreased to 20/200 with an intraocular pressure of 4 mmHg. He underwent phacoemulsification and aspiration, implantation of the intraocular lens, and encircling with a silicone tire. His visual acuity improved to 20/20 and stable for more than one year postoperatively. The intraocular pressure in his right eye increased to 12 mmHg, and maculopathy was resolved entirely. It was suggested that an encircling buckle obstructed the uveoscleral outflow through the cyclodialysis and increased intraocular pressure. Concurrent cataract surgery and encircling was sufficient to improve the vision.

Visual Results

Purpose. Studying the prevalence and functional results of cataract surgery and factors that negatively affect postoperative visual functions in the population of the Republic of Bashkortostan. Material and methods. The study was carried out on the basis of a pilot descriptive population study – Ural Eye and Medical Study (UEMS), conducted on the basis of the Ufa Research Institute of Eye Diseases. This analysis included 5 885 people aged 40 and over with data on performing cataract surgery. Poor visual outcome after cataract surgery was defined with uncorrected visual acuity below 0.3. Statistical data analysis was performed using the IBM SPSS Statistics application package. Results. The prevalence of cataract surgery was 6.1% (95% confidence interval (95% CI) 5.5–6.8%). A higher frequency of operations was associated with the age factor (odds ratio – OR 1.13, 95% CI 1.11–1.15%, p<0.001), male gender (OR 1.92, 95% CI 1.43–2.59, p=0.003), urban living (OR 1.37, 95% CI 1.04–1.80, p=0.02) and widowhood (OR 1.57, 95% CI 1.13–2.17, p=0.006). Low visual results after cataract surgery, considering the maximum postoperative correction, were found in 16.1% of cases (81 eyes). The main reasons for the low postoperative outcome: refractive error (40.4%), macular degeneration (18.5%), glaucoma (16.0%), posterior capsule opacification (13.6%) and diabetic retinopathy (12.3%). Conclusion. The obtained results of good postoperative uncorrected visual acuity amounted to 73.1% and turned out to be quite close to international standards (80%). The main reasons for the low visual results of cataract surgery were refractive error and age-related macular degeneration. Key words: population study, cataract surgery, the prevalence of cataract surgery.

Demographic Features

Background: The aim of this study is to determine the socio-demographic profile of people accessing cataract surgery at a free cataract surgical Camp in Kafanchan.Methods: One hundred and nine participants had manual small cataract incision surgery with intraocular lens over a three-month period (September to November 2018) and were followed up for two months. Visual acuity was assessed at first day and two months post-op along with refraction and best corrected visual acuity. Their socio-demographic features along with duration of lost vision and cause of delay in cataract surgery were also noted.Results: Fifty-five males and fifty- four females had cataract surgery and were followed up for two months post-op. Fifty (45.9%) had no formal education while fifty-nine (54.1%) had formal education. Among those with formal education 59% (34) were males while 41% (20) were females. Majority of participants earned less than two hundred and fifty thousand naira (six hundred and twenty-five US dollars) annually. Eighty-two (75%) of participants were Christians and 71 (65%) lived in rural areas. Sixty-five (60%) had lost vision in the index eye more than one year prior to presentation for surgery and the main reason in this study for delay in having cataract surgery was immaturity of the cataract.Conclusions: Some socio-demographic factors are barriers to cataract surgery.

Purpose. To present a case of cataract surgery performed in a patient with a refractive corneal inlay in place.Methods. A 48-year-old female patient presented to our institute with bilateral cataract. The patient had undergone refractive corneal inlay implantation three years ago in her right, nondominant eye for presbyopia correction. Biometry and intraocular lens (IOL) power calculation were performed without removing the inlay. Phacoemulsification and IOL insertion were carried out in both eyes in a usual manner.Results. On day one postoperatively, the patient achieved binocular uncorrected distance visual acuity 20/20 and uncorrected near visual acuity J1. The vision remained stable during the one-year follow-up period.Conclusion. Cataract surgery was performed in a standard manner in a patient with Presbia Microlens corneal inlay in place. Visual outcomes for both near and distance vision were satisfactory.

Purpose. Few studies have focused on long-term postoperative visual quality. This study aimed to evaluate the long-term visual quality after microincision cataract surgery (MICS). Methods. 96 patients (144 eyes) diagnosed with age-related cataracts were enrolled in this one-year study. The patients underwent MICS and received aspheric monofocal intraocular lens implants. Uncorrected distance visual acuity (UDVA) was evaluated together with best-corrected distance visual acuity (BCDVA), best-corrected near visual acuity (BCNVA), contrast sensitivity, and surgically induced astigmatism (SIA). Results. Compared to preoperative measurements, UDVA, BCDVA, and BCNVA were significantly better after surgery (P<0.001), and they remained stable throughout follow-up. Contrast sensitivity was also significantly better after surgery (P<0.001). Mean SIA during follow-up was 0.57 ± 0.33 D at 1 week, 0.36 ± 0.25 D at 3 months, and 0.18 ± 0.16 D at 1 year. SIA decreased significantly during the postoperative period (P<0.001). The 1-year postoperative absolute residual diopter value was 0.32 ± 0.28 D. Conclusion. MICS can provide excellent visual quality as soon as on postoperative day 1, which persists during the follow-up period of 1 year. In contrast to previous studies, SIA decreases over time and may not completely stabilize for as long as 1 year postoperatively.

Objective: To evaluate the role of eye camp in reducing avoidable blindness in Nepal. Methods: A cross sectional camp-based study was conducted in a remote village of Eastern Nepal, where a six days eye screening and free surgical camp was done. Results: A total of 467 people were screened, where 280 (60%) were males and 187 (40%) females. Mean age of the patient was 47.6 years. Age related cataract 165 (17.7%) was the commonest cause of decreased vision followed by refractive error 105 (11.2%). Among 165 cataract patients, 81 (49.1%) underwent cataract surgery. The mean age of the operated patient was 74.9 years. Among the operated eyes, visual impairment was present in 56 (69.1%) eyes and blindness in 25 (30.9%). After cataract surgery, visual acuity was restored to 6/6-6/18 in 58 (71.6%), 6/24-6/60 in 18 (22.2%) and five (6.2%) had visual acuity of <6/60. The causes of poor visual acuity in these patients were corneal edema (three cases), anterior uveitis (1 case) and optic atrophy (1 case). Pterygium excision (seven cases), entropion correction (two cases), chalazion I&C (one case) were other surgery performed in the camp. Refractive error was corrected by prescribing glasses. Conclusion: Cataract was found to be the major cause of blindness followed by refractive error. Conducting eye screening and surgical camps helps in restoring vision to the residents of remote areas, thus reducing the burden of blindness due to cataract and refractive error.

Phacoemulsification Cataract Surgery

Abstract Background Accumulating evidence suggests that refractive stabilization occurs rapidly following small incision cataract surgery. Nonetheless, many guidelines still suggest waiting four to 6 weeks before prescribing corrective lenses. This study was undertaken to supplement the existing literature regarding refractive stabilization, and evaluate multiple contributing factors that could dissuade clinicians from confidently correcting refractive error in the early post-operative course following routine cataract surgeries. Methods Adult patients undergoing phacoemulsification cataract surgery with uncomplicated surgeries and post-surgical courses at the Calgary Ophthalmology Centre (Calgary, Alberta, Canada) were included in this prospective observational case series. Exclusion criteria included known corneal dystrophies, infectious keratitis, complicated surgery or toric/multifocal IOLs. Data was collected at weekly intervals for a total of 6 weeks. Collected data included autorefraction, visual acuity, corneal pachymetry, and effective lens position. Results One hundred six eyes of 104 patients were included in this study. Post-operative sphere, cylinder and spherical equivalent were not significantly different at any post-operative week compared with week six, and 80–86% of patients were within 0.5D of last follow-up spherical equivalent at any week. The secondary outcomes of central corneal thickness, effective lens position and visual acuity did, however, exhibit significant differences between early post-operative weeks and last follow-up values. Conclusions These data suggest that refractive error can be effectively measured and corrected as early as one-week post-operatively in the majority of patients, though other measures of post-operative stability including central corneal thickness, effective lens position and visual acuity can require up to 4 weeks to stabilize. Thus a conservative and pragmatic approach may be to wait until 4 weeks post-operatively prior to obtaining refractive correction following uncomplicated phacoemulsification cataract surgery.

Purpose. To describe the surgical technique and outcomes of combined Descemet’s stripping endothelial keratoplasty and medium incision manual cataract surgery (MICS) in Chinese eyes. Methods. Surgery was performed in 8 eyes of 7 patients (5 females, 2 males). Primary outcomes included success of the surgery and final outcomes. Results. Surgery was performed in patients with Fuchs’ endothelial dystrophy and cataract (mean age 75.5±3.64 years). MICS tunnel was used to insert the donor lenticule into the anterior chamber. All surgeries were performed successfully. Graft dislocation was seen in 1 eye requiring repositioning with intracameral sulfur hexafluoride gas on the first postoperative day. Graft rejection was noted in one patient at the end of one year. The mean decimal best-corrected visual acuity improved from 0.1±0.07 to 0.3±0.15. Suboptimal visual acuity in 2 cases was due to radiotherapy-related optic neuropathy (n=1) and myopic maculopathy (n=1). The mean target spherical refraction was -1.11±0.17 diopters (myopic) and the mean achieved spherical refraction was 1.18 ± 0.87 diopters (hyperopic) resulting in a mean hyperopic shift of 2.2 diopters. Conclusions. The approach of combined Descemet’s stripping endothelial keratoplasty and MICS is a viable surgical technique for cases with endothelial dysfunction and cataract.

Purpose: To investigate the indications, clinical outcomes, and complications of secondary piggyback intraocular lens (IOL) implantation for correcting residual refractive error after cataract surgery. Methods: In this prospective interventional case series, patients who had residual refractive error after cataract surgery and were candidates for secondary piggyback IOL implantation between June 2015 and September 2018 were included. All eyes underwent secondary IOL implantation with the piggyback technique in the ciliary sulcus. The types of IOLs included Sulcoflex and three-piece foldable acrylic lenses. Patients were followed-up for at least one year. Results: Eleven patients were included. Seven patients had hyperopic ametropia, and four patients had residual myopia after cataract surgery. The preoperative mean of absolute residual refractive error was 7.20 ± 7.92, which reached 0.42 ± 1.26 postoperatively (P < 0.001). The postoperative spherical equivalent was within ±1 diopter of target refraction in all patients. The average preoperative uncorrected distance visual acuity was 1.13 ± 0.35 LogMAR, which significantly improved to 0.41 ± 0.24 LogMAR postoperatively (P = 0.008). There were no intraor postoperative complications during the 22.4 ± 9.5 months of follow-up. Conclusion: Secondary piggyback IOL implantation is an effective and safe technique for the correction of residual ametropia following cataract surgery. Three-piece IOLs can be safely placed as secondary piggyback IOLs in situations where specifically designed IOLs are not available.
