Abstract

Purpose: To investigate the safety and refractive outcomes of Nd:YAG capsulotomy in pseudophakic eyes with the light-adjustable intraocular lens (LAL) both before and after completing the light delivery device lock-in treatments.

Setting: Private practice in Orange, California.

Design: Retrospective, comparative study.

Methods: Patients were divided into 2 groups according to the timing of their YAG capsulotomy (Group I underwent YAG capsulotomy before lock-in treatments and Group II underwent YAG capsulotomy on completion of lock-in treatments). Sphere, cylinder, axis, spherical equivalent (SE), uncorrected distance visual acuity (UDVA), and corrected distance visual acuity (CDVA) were compared preoperatively and postoperatively using 2-tailed paired t tests. Postoperative data were measured 1 month after Nd:YAG capsulotomy. The α level (type I error) was set at 0.05.

Results: The LAL was successfully implanted in 485 eyes from January 2020 to March 2023. 10 eyes (0.02%) needed YAG capsulotomy before the completion of lock-in treatments (Group I), and 28 eyes (5.77%) needed YAG capsulotomy after the lock-in was completed (Group II). Postoperative CDVA significantly improved compared with preoperative values in both groups. Changes in sphere, cylinder, axis, SE, and UDVA preoperative and postoperative measurements were not statistically significant ( P > .05) in both groups.

Conclusions: YAG capsulotomy can be safe and effective for patients with the LAL who develop posterior capsular opacification during the adjustment period. There were no significant changes in sphere, cylinder, axis, or spherical equivalence after YAG capsulotomy in both groups.

Nd:YAG囊膜切开术治疗可调光人工晶体的临床评价。

目的：探讨光可调晶状体（LAL）在完成光传递装置（LDD）锁定治疗前后对掺钕钇铝石榴石（Nd:YAG）假晶状体囊切开术的安全性和屈光效果。背景：美国加利福尼亚州奥兰治的私人诊所。设计：回顾性比较研究。方法：根据YAG切开时间将患者分为两组（I组在闭锁治疗前进行YAG切开，II组在闭锁治疗完成后进行YAG切开）。采用双尾配对t检验比较术前和术后球体、圆柱形、轴形、球面等效、未矫正视力和最佳矫正视力。术后数据在Nd:YAG囊切除术后1个月测量。α水平（I型误差）设为0.05。结果：2020年1月至2023年3月，成功植入了485只眼。ⅰ组在闭锁完成前需行YAG囊切除术10眼（0.02%），ⅱ组在闭锁完成后需行YAG囊切除术28眼（5.77%）。两组术后BCVA均较术前显著改善。两组术前、术后球、柱、轴、SE、UCVA的变化均无统计学意义（p < 0.05）。结论：YAG包膜切开术对LAL患者在调整期间发生PCO是安全有效的。两组YAG囊切除术后的球体、圆柱体、轴线或球体等效性均无显著变化。
