Abstract

Intraocular surgery e.g., cataract surgery with PCIOL implantation is one of the leading causes of corneal endothelial injury and change in the functionality of the cornea. This observational study was conducted in the Department of Ophthalmology of Combined Military Hospital (CMH), Dhaka Cantonment, Dhaka, Bangladesh, between January and July of 2016, to assess and compare functional changes in cornea (i.e., endothelial thickness) after phacoemulsification with posterior chamber intraocular lens (PCIOL) implantation and manual small incision cataract surgery (MSICS) with PCIOL implantation. A total of 80 patients of age-related cataract were randomly selected based on inclusion and exclusion criteria. All patients underwent complete ophthalmic evaluation pre- and post-operatively (at day 1, after 1 week and 3 months) specifically for observation of the endothelial changes in cornea. Specular microscopy was done to assess corneal endothelial change. The mean central corneal thickness was increased at day 1 (564.71±22.45μ vs. 555.10±40.57μ), after 1 week (539.43±22.16μ vs. 535.08±38.87μ) and 3 months (523.49±21.29μ vs. 520.05±33.68μ) after phacoemulsification and MSICS from their preoperative value (508.72±23.96μ vs. 503.62±32.06μ) respectively. However, the differences were not statistically significant between two groups (P>0.05). The mean percentage of central corneal thickness change at day1, after 1 week and after 3 months following cataract surgery were found 11.01±6.30% and 10.22±26.54% at day 1, 6.04±7.52% and 6.25±21.24% after 1 week, 2.90±11.14% and 3.26±5.05% after 3 months in phacoemulsification and MSICS cases respectively. However, no statistically significant difference was observed in percentage of central corneal thickness change of both groups (P>0.05). To summarize, an increased central corneal thickness was observed after phacoemulsification and SICS from their preoperative values. Mugda Med Coll J. 2024; 7(1): 14-18

带 PCIOL 的超声乳化术与带 PCIOL 的人工小切口白内障手术的功能性内皮变化比较

眼内手术（如植入 PCIOL 的白内障手术）是导致角膜内皮损伤和角膜功能变化的主要原因之一。这项观察性研究于 2016 年 1 月至 7 月期间在孟加拉国达卡的达卡县联合军事医院（Combined Military Hospital，CMH）眼科进行，旨在评估和比较超声乳化术联合后房型人工晶体（PCIOL）植入术和人工小切口白内障手术（MSICS）联合 PCIOL 植入术后角膜的功能变化（即内皮厚度）。根据纳入和排除标准，随机选取了 80 名老年性白内障患者。所有患者均在术前和术后（第 1 天、1 周后和 3 个月后）接受了全面的眼科评估，以观察角膜内皮的变化。窥镜检查用于评估角膜内皮的变化。超声乳化和 MSICS 术后第 1 天（564.71±22.45μ vs. 555.10±40.57μ）、1 周后（539.43±22.16μ vs. 535.08±38.87μ）和 3 个月后（523.49±21.29μ vs. 520.05±33.68μ）的平均角膜中央厚度分别比术前值（508.72±23.96μ vs. 503.62±32.06μ）有所增加。然而，两组之间的差异无统计学意义（P>0.05）。白内障手术后第 1 天、1 周后和 3 个月后中央角膜厚度变化的平均百分比分别为 11.01±6.30%和 10.22±26.54%，1 周后为 6.04±7.52%和 6.25±21.24%，3 个月后为 2.90±11.14%和 3.26±5.05%。然而，两组患者角膜中央厚度变化的百分比差异无统计学意义（P>0.05）。总之，观察到超声乳化术和 SICS 术后角膜中央厚度比术前值有所增加：14-18
