囊袋张力环在不全脱位晶状体白内障手术中的应用

Application of capsular tension ring in surgery for cataract with lens subluxation

目的分析囊袋张力环在伴晶状体不全脱位白内障超声乳化手术中的应用价值。方法对12例（12眼）晶状体不全脱位白内障行囊袋内植入张力环联合超声乳化及后房型人工晶体植入。结果术后随访3月，12例人工晶体均正位，眼压在正常范围，术后视力均较术前提高，0．6以上6眼，0．4—0．5者3眼，0．3以下者3眼。无严重并发症。结论囊袋张力环能够保持白内障手术时晶状体囊袋的稳定性，拓宽了后房型人工晶体植入术的适用范围，防止术后人工晶体偏位，有助于患者视力的恢复。

Objective To anality the application value of capsular tension ring in surgery for cataract with lens subluxation. Methods 12 patients（ 12 eyes）diagnosed cataract with lens subluxation were involved. All patients received phacoemulsification with capsular tension ring and intraocular lens implantation. Results All patients completed 3 months of follow up. The intraocnlar lens of all patients were no moving and the intraocular pressuea of all patients were nomal. At the last postoperative examination, best corrected visual acuities of all eyes were increased. The visual acnities of 6 eyes were up 0. 6 and 3 eyes were between 0.4 ~ 0. 5, the visual acuities of 3 eyes were belowe 0. 3. These was no serious complications in this study. Conclusion Capsular tension ring can maintain the stability of capsular of lens during surgery and wide the application rang of posterior chamber intraocular lens. Application of capsular tension ring can keep the stability of intraocular lens. It is helpful for vision increasing.
