囊袋张力环在晶状体半脱位白内障超声乳化手术中的应用

目的评价晶状体囊袋张力环（CTR）在白内障合并晶状体半脱位行超声乳化白内障吸除术中的应用价值。方法对11例12眼白内障合并晶状体半脱位患者行超声乳化白内障吸除术，术中连续环行撕囊后植入CTR，超声乳化摘除白内障，囊袋内植入后房型人工晶体，若晶状体半脱位〉1／2需植入固定孔型CTR，将CTR固定孔上的聚丙烯线固定于悬韧带离断一侧板层巩膜壁上。结果所有植入的人工晶体均位于正位。术后随诊3～9个月，矫正视力0、1～0．4者4眼，0、5～0．8者5眼，〉0．8者3眼。结论在白内障合并晶状体半脱位患者行超声乳化白内障吸除术中植入囊袋张力环是安全有效的方法，有利于保持囊袋的完整，便于后房型人工晶体植入，防止人工晶体的偏位，减少手术并发症，术后视力恢复快。

Clinical application of capsular tension ring during phacoemulsification for subluxated lens with cataract

Objective To evaluate the efficiency of capsular tension ring implantation during phacoemulsification for subluxated lens with cataract.Methods Phacoemulsification combined with inrtraocular lens implamtation(IOL) was performed on 12 eyes of 11 patients.Capsular tension ring was implanted during phacoemulsification.Results Tab capsular tension ring was successfully implanted in 12 eyes.IOL position in all cases were normal.The corrected visual acuity was 0.1~0.4 in 4 eyes,0.5~0.8 in 5 eyes,over 0.8 in 3 eyes.Conclusion The capsular tension ring implantation during phacoemulsification is a safe and effective method for subluxated lens with cataract.It can prevent the IOL decentration and decrease the complications.
