ABSTRACT
Purpose: To assess the refractive outcomes and effect on endothelial cell density of refractive implantable lens (RIL) implantation following deep anterior lamellar keratoplasty (DALK). Methods: A retrospective study was conducted on 10 eyes of 10 patients who had undergone DALK and subsequently underwent toric RIL implantation. The patients were followed up over a period of 1 year. The parameters compared were uncorrected and best corrected visual acuity, spherical and cylindrical acceptance, mean refractive spherical equivalent, and endothelial cell counts. Results: There was a significant improvement (P < 0.05) from preoperatively to 1 month postoperatively in the mean log of minimum angle of resolution (logMAR) uncorrected distance visual acuity (UCVA; 1.1 ± 0.1 to 0.3 ± 0.1), spherical refraction (5.4 ± 3.8 to 0.3 ± 0.1 D), cylindrical refraction (5.4 ± 3.2 to 0.8 ± 0.7 D), and MRSE (7.4 ± 3.5 to 0.5 ± 0.4 D). Three patients achieved spectacle independence for distance vision with a residual MRSE less than 1 D in the other cases. A stable refraction was maintained up to 1 year follow?up in all cases. There was a 2.3% mean decline in endothelial cell counts at 1 year of follow?up. No intraoperative or postoperative complications were seen in any case up to 1 year of follow?up. Conclusion: RIL implantation is an effective and safe procedure for the correction of high ametropia post?DALK
ABSTRACT
Purpose: To compare different endophthalmitis prophylaxis methods adopted in cataract surgery (manual small-incision cataract surgery and phacoemulsification) between the years 2013 and 2021 in the community eye care section of a tertiary eye care hospital in South India and report their outcomes. Methods: All cataract surgeries performed from January 2013 to December 2021 (2,46,874 surgeries) at a single center were included in this retrospective study. The different endophthalmitis rates with each regimen were analyzed and evaluated. Results: 70,081 surgeries were performed from January 2013 to February 2015, where Tobramycin was added to Balanced Salt Solution (BSS) (Group A). From March 2015 to January 2017, 63,245 surgeries were performed when intracameral Moxifloxacin was given (Group B). From February 2017 to December 2021, 1,13,548 surgeries were performed were Amikacin was added to BSS (Group C). In total, 42 cases of postoperative endophthalmitis were reported during the study period (0.02%). There was no significant difference in the endophthalmitis rates between groups A and B (P = 0.4152); however, there was a significant decrease in endophthalmitis rates in group C when compared with group A (P = 0.04) and group B (P = 0.006). Conclusion: There was a significant reduction in the rates of endophthalmitis following the addition of amikacin in irrigating BSS. Nocardia was one of the predominant organisms isolated from these endophthalmitis patients. This is the first single-center study to report a comparative analysis of different endophthalmitis prophylactic measures in a community eye care set up with a high incidence of Nocardia endophthalmitis prevented with amikacin in BSS irrigating solution.
