玻璃体切割术后白内障超声乳化术

Cataract phacoemulsification after vitrectomy

目的 探讨玻璃体切割术后白内障超声乳化手术的特点、安全性和结果。方法 回顾性分析 1999年 7月～2 0 0 0年 3月本中心对 2 1例 2 1眼玻璃体切割术后白内障实施超声乳化手术 ,分析了术中的难点及并发症。共随访 6～12 m o。结果 玻璃体切割术后白内障手术难度大 ,术中易出现并发症 :前房变浅瞳孔缩小者 8例 ;悬韧带断裂晶状体坠入玻璃体腔 2例 ;后囊膜破裂 2例。术后矫正视力提高者 19例 (90 .48% ) ,视力无改变 2例 (9.5 2 % )。结论 玻璃体切割术后白内障手术难度高、并发症多 ,采用超声乳化术易于调节和稳定眼压 。

Objective To determine the characteristics, safety and results cataract phacoemulsification after vitrectomy Methods In this prospective study,phacoemulsification was performed in 21 eyes that had vitrectomy between July 1999 and March 2000 Surgical difficulties and complications and visual acuity results were analyzed Follow up ranged from 6 to 12 months Results The incidence of surgical problems and complications was higher than usual∶sudden changes in anterior chamber depth and pupil size during surgery occurred in 8 eyes; Lens zonules broke in 2 eyes; Posterior capsule tear occurred in 2 eyes Postoperatively, best visual acuity improved in 19 eyes(90 48%) and there was no change in 2 eyes (9 52%) Conclusion Phacoemulsification in vitrectomized eyes presented more problems and complications than usual However it seems to be safer and can minimize the risk of intraoperative eye hypotony or collapse
