Immediate Sequential Bilateral Cataract Surgery in Covid-19 Pandemic - A Prospective Study in a Tertiary Eye Care Centre of Eastern India

BACKGROUND Immediate sequential bilateral cataract surgery (ISBCS) is the procedure in which both eyes are simultaneously operated in a single hospital visit. The onset of corona virus disease-19 (COVID-19) pandemic has raised the interest among ophthalmic surgeon in considering immediate sequential bilateral cataract surgery to reduce hospital visit of patients. This study was done to assess the intraoperative and post-operative complications and average number of hospital visits required after performing immediate sequential bilateral cataract surgery in COVID-19 pandemic. Also, the post-operative visual outcomes were evaluated. METHODS Patients with visually significant bilateral cataract with best corrected visual acuity ≤ 6/18 in better eye, axial length within range of 21 - 25 mm and age >18 years with no ocular and systemic co-morbidity were included in the study. All patients underwent immediate sequential bilateral cataract surgery from July 2020 to September 2020. Strict intraoperative protocols were followed in all cases. Intracameral injection of 0.1 ml moxifloxacin 0.5 % (vigamox / Novartis health care Pvt Ltd. Texas, USA) was given at the end of surgery in all cases. Intraoperative and post-operative complications, visual and refractive outcomes were analysed. RESULTS Sixty-four eyes of 32 patients with mean age 55 ± 2.82 years (range: 48 - 71 years) were included in the study. The mean pre-operative best corrected visual acuity was 0.64 ± 0.08 logarithm of minimum angle of resolution which improved significantly to 0.03 ± 0.03 at the end of second follow up on day 14 (P < 0.0001). The mean post-operative spherical equivalent was -0.22 ± 0.48 D. The target refraction within ± 0.50 D was achieved in 56 eyes (87.50 %) and within ± 1.0 D in all eyes. No vision threatening complications such as endophthalmitis, cystoid macular oedema, retinal detachment or corneal decompensation occurred in any of eyes. Total hospital visits were reduced to four per patients for both eye surgeries. CONCLUSIONS Immediate sequential bilateral cataract surgery may be considered as preferred practice in selected cases to reduce the risk of cross infection of COVID-19 by short hospitalization and less follow up visits.

Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Background: Amblyopia is more common in children with high astigmatism, but factors contributing to development of amblyopia and visual outcomes are not fully understood. Objective: To evaluate the effect of amblyopia on the clinical outcomes in children with ⩾1.75 diopter (D) astigmatism. Methods: We reviewed the medical records of children with ⩾1.75 D astigmatism with and without amblyopia (amblyopes group and non-amblyopes group). The mean age, gender, amount and type of ocular deviation, presence of convergence insufficiency (CI), stereopsis, time of initial spectacle use and follow-up time, differences in best-corrected visual acuity (VoD) and spherical equivalent (SE) between eyes were assessed and compared between the groups. Best-corrected visual acuity (BCVA), mean SE, astigmatism measurements were assessed and compared between amblyopic, fellow, and non-amblyopic eyes. Results: The records included 68 eyes of 34 children with amblyopia and 56 eyes of 28 children without amblyopia. The mean age, gender, amount and type of ocular deviation, presence of CI, stereopsis, time of initial spectacle use, follow-up time, and the difference in SE did not differ between groups. In amblyopes, exodeviation was more common and statistically greater in near (33 cm) than at distance (6 m) (p = 0.005). The mean BCVA and astigmatism values were statistically different between amblyopic, fellow, and non-amblyopic eyes. Conclusion: A greater near than distance exodeviation and higher mean astigmatism value were found in amblyopic children with astigmatism.

Abstract: Introduction and aim: The correction of aphakia might be a challenge for the surgeon. The aim of this study is to describe the authors’ experience with the implantation of the retropupillary iris clip intraocular lens. Method: Patients between January 2014 and December 2015 were included in the retrospective study. Retropupillary implantation of iris clip intraocular lens VRSA 54 (AMO Advanced Medical Optics, USA) was performed in all cases. The minimum follow up period was three months. The stability of the intraocular lens and the intraoperative and postoperative complications and the visual acuity were evaluated. Results: During this time period 11 cases (1 female, 10 males) were included in the study. The mean age at the time of the implantation was 57.7 years (between 25–74 years). In 4 cases the iris clip lens was implanted during the first intervention, in 7 cases during the secondary procedure. In all cases the lens was fixated onto the iris posteriorly. The best corrected visual acuity before the iris clip implantation was 0.43 (0.1–1.0) and postoperatively at the time of the follow up 0.49 (0.04–1.0). Conclusions: With the use of the retropupillary implanted iris clip intraocular lens all of the patients could have been rehabilitated without major complications. Orv. Hetil., 2017, 158(1), 20–24.

AIM: To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis. METHODS: Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy (PPV) combined with scleral shortening were reviewed. Axial length (AL), the height of macular retinoschisis, the height of retinal detachment if existed, the diameter of macular hole if existed and best corrected visual acuity (BCVA) were obtained. The preoperative and postoperative parameters were compared. RESULTS: At postoperative 24mo, the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51 μm (t=8.064, P<0.0001; Z=-5.086, P<0.0001) respectively. In addition, the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38 μm and 183.68 μm (Z=-4.457, P=0.000008; Z=-2.983, P=0.003) respectively. Meanwhile, the postoperative BCVA was improved markedly (Z=-2.126, P=0.033). CONCLUSION: Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis, whether or not macular hole and retinal detachment are present.

Background/aimsTo investigate the surgical outcomes of posterior scleral reinforcement (PSR) using genipin-cross-linked sclera to treat macular hole retinal detachment (MHRD) in highly myopic eyes.MethodsNineteen patients with high myopia (19 eyes) with MHRD were treated sequentially with genipin-cross-linked PSR and were followed at least for 1 year after the surgery. The best corrected visual acuity (BCVA), axial length (AL), optical coherence tomography (OCT) outcomes and the complications were evaluated.ResultsMacular hole was closed in 73.7% of the eyes, foveal reattachment rate was 100%. The mean logMAR BCVA improved from 1.27±0.55 preoperatively to 0.88±0.55 postoperatively. The preoperative AL (29.88±1.97 mm) was decreased (27.73±1.84 mm) after the operation (p<0.001).ConclusionsFor at least a 1-year period of follow-up, PSR with genipin-cross-linked sclera should be considered as a preferred surgical approach to treat MHRD in highly myopic eyes, especially when foveal retinoschisis is also documented.

Purpose: It was the aim of this study to determine the efficacy of intravitreal ranibizumab as treatment of choroidal neovascularizations associated with pathologic myopia. Materials and Methods: In an uncontrolled, prospective time series cohort study, 65 eyes of 64 consecutive patients with choroidal neovascularization associated with pathologic myopia were treated with intravitreal ranibizumab and observed over 12 months. The change in best-corrected visual acuity (BCVA) at 6 and 12 months served as primary end point. Safety, central retinal thickness, neovascularization activity on fluorescein angiography and the number of ranibizumab injections were secondary end points. Results: BCVA improved significantly throughout the follow-up (p = 0.001). The mean BCVA was 0.2 at baseline (SD 0.13) and 0.4 at 12 months (SD 0.21). Improvement was strongest within the first 3 months (p = 0.0001). The mean central retinal thickness showed a reduction from 313 μm (SD 82) to 243.5 μm (SD 31; p = 0.0001). Conclusion: Intravitreal ranibizumab offers a safe and effective treatment for choroidal neovascularizations in pathologic myopia.

Aim: To assess the complications and visual outcomes associated with cataract surgery in camp patients operated at a tertiary centre. Materials and methods: In a retrospective study, 206 outreach camp patients had undergone cataract surgeries with posterior chamber intraocular lens implantation under peribulbar anesthesia over a period of 6 months. Post-operative complications on Day 1 were graded as per Oxford Cataract Treatment and Evaluation Team (OCTET) definitions. One month postoperative complications, best corrected visual acuity and refractive errors were assessed. Results: 206 eyes underwent cataract extraction with PCIOL implantation. Small incision cataract surgery (SICS) was the commonest method (78.6%) used. The most common first post-operative day complication was mild iridocyclitis (26.2%). The complications were based on OCTET definitions, and showed that 33 % had Grade I and 3.4 % had Grade II complications. The major post-operative complication after 4 weeks of surgery was posterior capsular opacity. 89.8 % of the eyes had a 4 week-post-operative best corrected visual acuity of e” 6/24. The commonest refractive error was myopia with against the rule astigmatism, seen in 86 out of 150 cases. Conclusion: High quality cataract surgery with a low rate of intra-operative complications and good visual outcome can be attained in camp patients operated in the base hospitals, thus justifying more similar screening camps to clear the vast cataract backlog.

Abstract Background: To evaluate the 12-month efficacy and safety of intravitreal conbercept for myopic choroidal neovascularization (CNV). Methods: A retrospective, observational study. Thirty-four eyes of 34 pathologic myopic patients with CNV were treated with intravitreal conbercept (IVC) 0.5 mg with a follow up of 12 months. After the first injection, administration of conbercept followed a pro re nata (PRN) regimen. Outcomes included best corrected visual acuity (BCVA), central retinal thickness (CRT), CNV size, the total number of treatments, and adverse events. Results: The mean patient age was 55.88 ± 16.17 years, and mean eye spherical equivalent was − 8.72 ± 3.75 D. The mean number of IVC over 12 months was 2.12 ± 0.69. Overall, best-corrected visual acuity（BCVA）improved from 0.86 ± 0.33 logMAR at baseline to 0.44 ± 0.32 logMAR at month 12 ( P < 0.001 ), mean improvement of vision was 4.12 ± 2.69 Snellen lines . Mean central retinal thickness reduced from 285.9 ± 104.6 μm at baseline to 192.1 ± 97.5 μm at month 12 (P < 0.001). Mean CNV size decreased from 0.52 ± 0.38 mm 2 at baseline to 0.31 ± 0.19 mm 2 at 12 months (P < 0.05). All the 34 eyes had reduced or stable size of CNV, thirty-two eyes (94.12%) showed absence of CNV leakage at the end of the study period. No severe complications were observed. Conclusion: Intravitreal conbercept 0.5mg was safe and effective for treatment of myopic CNV over 12 months in real-life setting.
