高龄白内障患者2种小切口手术疗效分析

目的探讨超声乳化白内障吸出术和小切口非超声乳化囊外摘除术在高龄白内障患者中的效果和并发症的发生情况。方法回顾分析并比较561例(同一患者先后行双眼手术者记为2例)高龄白内障患者施行超声乳化吸除术和小切口非超声乳化囊外摘除术术后1、33、0 d视力和术后并发症的发生情况。结果施行超声乳化白内障吸出术组253例,小切口非超声乳化囊外摘除术组308例。两种术式术后视力为0.2～0.3患者数均达50%以上,并且随着时间增长视力显著提高;核硬度大于或等于Ⅲ的情况下采用两种术式主要并发症发生率均低于10%,核硬度大于或等于Ⅳ的情况下采用超声乳化白内障吸出术主要并发症发生率稍高。结论核硬度大于或等于Ⅳ的高龄白内障患者采用小切口非超声乳化囊外摘除术较超声乳化白内障吸出术视力恢复快,术后并发症少,治疗费用低。

Efficacy analysis of two kinds of small incision operations on senility cataracts patients

Objective To evaluate the effects and complications incidence of phacoemulsification(PNACO)and small incision non-phacoemulsification cataract extraction on senility cataracts patients.Methods 561 cases′ eyesight and complications incidence(taking the same patient do binoculus successively as two cases)that using phacoemulsification or small incision non-phacoemulsification cataract extraction separately after 1,3 and 30 days were retrospected and compared.Results 253 cases used phacoemulsification and 308 cases used small incision non-phacoemulsification cataract extraction.The two both got over 50% in eyesight during 0.2～0.3 and it increase as time last;complications incidence rate of two groups with nuclear hardness less than or egual to Ⅲ were less than 10%,while complications incidence rate of PNACO group with nuclear hardness greater than or egual to Ⅳ had a little greater.Conclusion Nuclear hardness patients with nuclear hardness greater than or egual to Ⅳ,Ⅳ patients using small incision non-phacoemulsification,cataract extraction may have quick recovering in eyesight and less complications incidence.
