Abstract

Purpose: To evaluate intraocular lens (IOL) rotational stability and capsular fusion process after cataract surgery with and without primary posterior continuous curvilinear capsulorhexis (PPCCC).

Setting: Fujian Provincial Hospital, Fujian, China.

Design: Prospective, intraindividual, randomized clinical trial.

Methods: This study included 56 adult patients (112 eyes) with bilateral cataract undergoing phacoemulsification cataract surgery with PPCCC in 1 eye (PPCCC group) and conventional cataract surgery in the contralateral eye (NPCCC group). IOL axis orientation and fusion footprint length were measured at 1 day, 1 week, 1 month, 3 months, and 1 year postoperatively using OPD-Scan III, while the capsular bend index (CBI) was assessed at the same timepoints using Pentacam AXL.

Results: No between-group difference was found in the absolute rotation from 1 day to 1 year (2.93 ± 1.72 vs 2.66 ± 1.61 degrees, P = .54). The absolute rotation from 1 week to 1 month in the NPCCC group was higher than that in the PPCCC group (1.65 ± 0.68 vs 1.27 ± 0.32 degrees, P = .01). At 1 month postoperatively, both fusion footprint length (9.11 ± 2.74 vs 10.67 ± 2.06 mm, P = .02) and CBI (2.92 ± 0.60 vs 3.25 ± 0.59, P = .03) were lower in the NPCCC group.

Conclusions: Cataract surgery involving PPCCC demonstrated comparable outcomes with conventional procedures regarding long-term IOL rotational stability and therefore is a promising option for adult patients with cataract scheduled for toric IOL implantation. PPCCC slightly reduces IOL rotation in the early postoperative period, which can be attributed to accelerated capsular fusion.

白内障手术后眼内晶状体旋转稳定性，有无原发性后方连续曲线囊外摘除术

目的：评估白内障手术后人工晶体（IOL）的旋转稳定性和囊膜融合过程：设计：中国福建，福建省立医院：设计：前瞻性、个体内、随机临床试验：本研究纳入了56例成年双侧白内障患者（112只眼），其中一只眼接受PPCCC白内障超声乳化手术（PPCCC组），另一只眼接受传统白内障手术（NPCCC组）。使用 OPD-Scan III 在术后 1 天、1 周、1 个月、3 个月和 1 年测量人工晶体轴线方向和融合足迹长度，并使用 Pentacam AXL 在相同时间点评估囊弯指数（CBI）：结果：术后1天至1年的绝对旋转度在组间无差异（2.93 ± 1.72 vs 2.66 ± 1.61度，P=0.54）。NPCCC 组 1 周至 1 个月的绝对旋转角度高于 PPCCC 组（1.65 ± 0.68 vs 1.27 ± 0.32 度，P=0.01）。术后 1 个月，NPCCC 组的融合足迹长度（9.11 ± 2.74 vs. 10.67 ± 2.06 mm，P = 0.02）和 CBI（2.92 ± 0.60 vs. 3.25 ± 0.59，P = 0.03）均低于 PPCCC 组：结论：在人工晶体长期旋转稳定性方面，PPCCC白内障手术的效果与传统手术相当，因此对于计划植入散光人工晶体的成年白内障患者来说，PPCCC手术是一种很有前途的选择。PPCCC在术后早期会略微减少人工晶体的旋转，这可能是由于加速了晶体囊的融合。
