小瞳孔白内障的超声乳化及折叠式人工晶状体植入术

目的探讨小瞳孔白内障的超声乳化及折叠式人工晶状体的手术技巧和临床效果。方法临床确诊的小瞳孔白内障患者46例54眼,经透明角膜隧道切口,采用钝性分离的方法扩大瞳孔,行环行撕囊、双手原位超声乳化及折叠式人工晶体囊袋内植入手术。结果术后随访5～12月,术后视力提高46眼占85.19%,视力≥0.5者34眼占62.96%,所有患者的瞳孔保持生理性圆形或是近圆形。手术并发症主要有角膜水肿、前房纤维素性渗出、后囊破裂。结论掌握合理的手术技巧,小瞳孔白内障的超声乳化术同样可以取得良好的手术效果。

Phacoemulsification and foldable intraocular lens implantation in microcoria cataract

Objective To explore the surgical techniques and the clinical effects of phacoemulsification and foldable intraocular lens implantation in microcoria cataract.Methods 46 cases(54 eyes)of microcoria cataract through transparent limbal tunnel incision were operated by using manual pupilloplasty first,then were performed by continuous circular capsulorhexis and used stable both hands to perform phacoemulsification and foldable intraocular lens implantation.Results Following up 5 to 12 months,the visual acuity got better in 46 eyes(85.19%);the visual acuity was 0.5 or better in 34eyes(62.96%).All the pupils recovered normal or near-normal.Complications of the surgery included corneal edema,significant fibrous exudation in the anterior chamber and posterior capsule rupture.Conclusion When we master rational skill of operation,we can obtain well clinical effects in phacoemulsification in the state of microcoria cataract.
