青光眼术后白内障超声乳化术

Phacoemulsification for complicated cataract after glaucoma surgery

目的探讨青光眼术后白内障超声乳化手术适应症、时机、手术方法和并发症。方法回顾性分析2002年1月至2004年2月青光眼术后白内障患者44例,其中预防性虹膜周边切除术8例,滤过性手术36例。对39例术前眼压控制在正常范围或仅局部药物能控制正常的病例做上方透明角膜内切口或颞侧角膜缘巩膜隧道切口,避开功能滤过区行白内障超声乳化术;对3例术前眼压须全身药物才能控制的病人,控制眼压后避开原手术区行白内障超声乳化联合小梁切除术。随访半年。结果视力均有不同程度提高结论,0.5以上33例,视觉电生理检查视功能损害与术前有明显差别,眼压均在正常范围。结论超声乳化手术是治疗青光眼术后白内障的有效方法。

Objective To evaluate the phacoemulsification for complicated cataracta after glaucoma surgery from operation indications, opportunities, operation methods. Methods From January 2002 to February 2004, 42 cases with the phacoemulsification for cataracta after glaucoma surgery were retrospective studied, including 8 cases with prophylactic peripheral iridectomy and 36 cases with filtering surgery. 39 cases whose ocular tensions were operated though a clear corneal incision or a scleral tunnel incision. In these 39 operations, we attended to avoid the primary filtering area. Other 3 cases whose ocular tensions had to be controlled in normal range by systemic administration were run combined phacoemulsifecation and trabeculectomy. All patients followed up half a year. Results The visual acuity of all eyes were improved after surgery. Among those,the acuity of 33 cases increased to≥0.5. By some visual electrophysiologic study, the visual function damage of all cases who had received surgery had significant difference compared to those who hadn't received surgery. Conclusion The phacoemulsifecation is an effective method for complicated cataract after glaucoma surgery.
