软壳技术在后极性白内障超声乳化手术中的应用

目的:探讨后极性白内障超声乳化手术有效控制并发症发生的技术与方法。方法:后极性白内障行超声乳化术中引入软壳技术者27例33眼,保护角膜及后囊膜,防止并发症发生,并观察手术前后视力的改善情况及并发症发生情况,分析软壳技术在术中的作用与价值。结果:后囊膜完整者28眼,其中6眼后囊膜混浊,在5只后囊膜破裂眼中,无玻璃体脱出,人工晶状体囊袋内固定均良好者33眼,视力显著提高,无明显并发症发生。结论:软壳技术的应用可以减少后极性白内障超声乳化手术的并发症,明显提高视力,对控制手术质量有重要意义。

Application of soft-shell technique in phacoemulsification in cases with posterior polar cataract

·AIM:To search for an effective technique to control the complications in phacoemulsification in eyes with posteri-or polar cataract.·METHODS:Twenty-seven cases(thirty-three eyes)with posterior polar cataract underwent phacoemulsifica-tion.Soft-shell technique was introduced to protect corneas and posterior capsule in the surgical procedure.Visual acuity(VA)and complications after operation were observed.Then the data were analyzed.·RESULTS:Twenty-eight eyes revealed intact posterior capsule,six of which revealed posterior capsule opacifi-cation.Five eyes developed posterior capsule rupture,however no vitreous prolapse.All eyes were implanted foldable intraocular lens in the capsular bags.The postoperative VA in all cases were improved without obvious complications.·CONCLUSION:The application of soft-shell technique in phacoemulsification is effective for improving VA,reduc-ing complications,and controlling surgical quality in cases with posterior polar cataract.·
