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。
Objective To investigate the effect and complications of phacoemulsification cataract extraction and small incision non-phacoemulsification extracapsular cataract extraction in elderly patients with cataract. Methods Retrospective analysis and comparison of 561 cases (the same patient was followed by binocular surgery were recorded in 2 cases) elderly cataract patients undergoing phacoemulsification and small incision non-phacoemulsification extracapsular cataract surgery 1,33,0 d visual acuity and surgery After the occurrence of complications. Results The results of phacoemulsification cataract extraction group 253 cases, 308 cases of small incision non-phacoemulsification extracapsular cataract group. The visual acuity of 0.2 ~ 0.3 in two kinds of operation were more than 50%, and visual acuity increased significantly with the increase of time. The main complication rates of the two kinds of operation were lower than those with nuclear hardness greater than or equal to Ⅲ 10%, nuclear hardness greater than or equal to the case of the use of phacoemulsification cataract surgery the main complication rate slightly higher. Conclusions Older cataract patients with nuclear hardness greater than or equal to Ⅳ have faster recovery of visual acuity than small phacoemulsification cataract extraction with less incision non-phacoemulsification, less postoperative complications and low cost of treatment.
