改良信封式截囊与开罐式截囊疗效比较

Compare the effect of modified envelope with can opener capsulectomy

目的：比较改良信封式截囊、开罐式截囊两种截囊方法行白内障囊外摘除及人工晶体植入对眼内组织的影响。方法：改良信封式截囊５４眼，开罐式截囊３０眼，术后住院７～１０ｄ。随访１２～１８个月分别观察。结果：改良组对眼内组织影响小，并发症少，视力恢复快，７～１０ｄ≥０．５者５９．２６％，≥１．０者２５．９３％；随访１２～１８个月，视力≥０．５者８１．４８％，≥１．０者５１．８５％，后发障发生率低。结论：改良信封式截囊是一种容易掌握。

Objective:To compare the effect of modified envelope technique with can opener technique in extracapsular cataract extraction and intraocular lens implantation.Methods:Modified envelope technique was performed on 54 eyes and can opener technique on 30 eyes.All patients were hospitalized for 7～10 days after operation and followed up for 12～18 months.Results:Modified technique caused less impact on intraocular tissue and fewer complications.The visual acuities of eyes recovered faster:≥0.5 in 59.26%,≥1.0 in 25.93% after 7～10 days;≥0.5 in 81.48% and≥1.0 in 51.85% at 12～18 months,the rate of after cataract was lower.Conclusions:The technique of modified envelope capsulectomy is easy to master,and its impact on intraocular tissue is less than can opener capsulectomy.
