目的：比较常规白内障手术后Hoya FY 60 AD、Hoya PY 60 AD和Alcon AcrySof SN 60 WF人工晶状体（IOL）之间的掺钕钇铝石榴石激光后囊膜切开术（LPC）发生率。研究方法：在这项回顾性比较研究中，纳入了3年内接受无并发症白内障手术的患者，并从激光诊所记录中确定了随后接受LPC的患者。比较了圆形边缘Hoya FY 60 AD、新型锐缘Hoya PY 60 AD三件式IOL和一件式AcrySof SN 60 WF IOL术后2年的LPC率。结果：共纳入1,265例白内障手术，49只眼（3.9%）在手术后2年内接受了LPC。植入FY 60 AD的315只眼睛中有28只（8.9%）在2年时接受了LPC，相比之下，254只眼睛中有11只（4.3%）植入了较新的锐方边PY 60 AD，696只眼睛中有10只（1.4%）植入了一片式SN 60 WF（P，0.05，卡方分析）。结论：白内障术后2年时，较新的锐缘Hoya PY 60 AD IOL的LPC发生率低于Hoya FY 60 AD IOL。在术后相同时间段内，单件式AcrySof SN 60 WF的LPC发生率低于两种三件式Hoya IOL。IOL边缘设计和材料效应的变化可能导致观察到的不同发生率。
Purpose: To compare neodymium-doped yttrium aluminum garnet laser posterior capsulotomy (LPC) rates between the Hoya FY60AD, Hoya PY60AD, and Alcon AcrySof SN60WF intraocu-lar lenses (IOLs) after routine cataract surgery. Methods: In this retrospective comparative study, patients undergoing uncomplicated cataract surgery over a 3-year period were included, and those subsequently undergoing LPC were identified from laser clinic records. LPC rates at 2 years postoperatively were compared between the round-edged Hoya FY60AD , the newer sharp-edged Hoya PY60AD three-piece IOLs, and the one-piece AcrySof SN60WF IOL. Results: A total of 1,265 cataract operations were included, and 49 eyes (3.9%) underwent LPC within 2 years of surgery. Twenty-eight of 315 eyes (8.9%) implanted with the FY60AD underwent LPC by 2 years, compared to eleven of 254 (4.3%) with the newer sharp square-edged PY60AD and ten of 696 (1.4%) with the one-piece SN60WF (P , 0.05, Chi-squared analyses). Conclusions: The newer, sharper-edged Hoya PY60AD IOL has a lower LPC rate than the Hoya FY60AD IOL at 2 years post-cataract surgery. The one-piece AcrySof SN60WF has a lower LPC rate than both the three-piece Hoya IOLs in the same time period postoperatively. Variations in IOL-edge design and material effect may have contributed to the different rates observed.
