人工晶体植入术后低视力原因分析

目的　分析小切口非超声乳化人工晶体植入术后低视力发生的原因。方法　对 2 18例 (2 4 3眼 )白内障小切口非超声乳化人工晶体植入术患者进行术后 1wk～ 6mo随访 ,观察矫正视力及眼部情况。结果　在术后 6mo2 7例 (34眼 )矫正视力低于 0 .3(13.99% )患者中 ,手术并发症 17眼 (6 .99% ) ,术前原有眼病 13眼 (5 .35 % ) ,两者并存者 4眼 (1.6 5 % )。结论　手术并发症和术前原有眼病是术后低视力发生的原因。减少手术并发症和重视白内障患者术前眼部情况检查 ,是降低白内障摘除人工晶体植入术后低视力发生的两个重要环节。

The cause analysis of low vision after IOL implantation

Objective To analysis the cause of low vision after small incisions non phacoemulsification and intraocular lens implantation.Methods The corrected visual acuity and ophthalmological examination of 218 case (243 eyes) treated with small incisions non phacoemulsification and intraocular lens implantation were follow up from 1 week to 6 months after operation.Results The corrected visual acuity of 27 case 34 eyes were <0.3(13.99%) , the cause of low vision were complication of operation in 17 eyes(6.99%), pre oculopathy (5.35%) in 13 eyes (1.65%) and both complication of operation and pre oculopathy in 4 eyes.Conclusions The main cause of low vision were both complication of operation and pre oculopathy. Reducing complication and paying attention to examination of pre oculopathy can decrease the occurrence of low vision in small incisions non phacoemulsification and intraocular lens implantation were.
