摘要
目的:为了让选择PMMA硬性人工晶体的患者也能达到或接近折叠人工晶体的良好效果,设计了一种新的手术切口。方法:采用角膜内3.0mm长的隧道切口,在植入人工晶体之前,沿角膜切口的两侧向后侧方巩膜扩大隧道,使其形成外口5.5mm的阶梯样隧道。选取病例156例实施该手术,并另设两个对照组:折叠晶体组和巩膜切口组。结果:术后观察,所有术眼切口完全闭合,未发现浅前房及低眼压,术后散光小,视力良好,效果满意。结论:对比发现,改良切口组与折叠晶体组的术后散光无统计学差异,与反眉式巩膜切口有统计学差异。
Objective： In order to achieve the similar effect with PMMA intraocular lens（IOL） to that with folded intraocular lens,we design a new incision. Methods： We make a 3. 0 mm incision in cornea for phacoimulsification. Before implanating IOL,we extend the incision into sclera. We have this operation on 156patients and contrast them to other 2groups. Results： After operation,all eyes are completely closed incision without shallow anterior chamber and low intraocular pressure. All eyes gets satisfied effect with little astigmatism and good vision. Conclusions： The improved incision can get the similar effect to folded IOL incision and better effect than sclera incision.
