白内障小切口非超声乳化术向超声乳化术转型中的技术转变体会

目的:探讨白内障小切口非超声乳化术向超声乳化术转型中的技术转变.方法:对2009年4月-2009年12月"光明工程"中白内障超声乳化手术转型期193例193眼的情况进行回顾性分析,同期行小切口非超声乳化吸除术患者43例48眼作对照.结果:对照组术后第1日裸眼视力大于或等于0.5的比例高于治疗组(P＜0.05),术后第1周、第1个月裸眼视力大于或等于0.5及术后第1个月最佳矫正视力大于或等于0.5的比例,两组比较差异无统计学意义(均P＞0.05).对照组术后主要并发症比率均低于治疗组(均P＜0.05).结论:小切口非超声乳化术向超声乳化术转型中,因技术差异较大,发生后囊破裂和角膜内皮水肿的几率较高,转型此手术要有熟练的显微手术基础、处理并发症的能力和一定的设备条件.

Clincal outcome in conversion from small incision sutureless to phacoemulsification cataract surgery

PURPOSE: To investigate the clinical outcome during the conversion from small incision sutureless cataract surgery (SICS) to phacoemulsfication cataract surgery (Phaco). METHODS: During the conversion period from SICS to phaco, 241 cataract cases were assigned to SICS and phaco surgery procedures. The intraoperative complications and early postoperative outcome were assessed. RESULTS: The 1st day visual acuity outcome (VA 0.5 or better) was lower in phaco grouop (p<0.05), however, the visual acuity outcomes were no longer statistically different at 1 week and 1 month visits (p>0.05 for each visit). Among 193 cases operations in phaco group, 51 cases (26.4%) developed corneal edema at 1 day visit, 13 cases(6.7%) had posterior capsular rapture, 5 cases(2.6%) had zonular rupture, 5 cases (2.6%) failed to implant IOL. These rates were higher than what were found in SICS group. CONCLUSIONS: The outcome of phaco cataract surgery is comparable with SICS during this conversion period. Techniques that the surgeons may pay attention to are also discussed.
