目的 :分析老年性白内障囊外摘出并人工晶体植入术后裸眼视力低下的原因及防治。方法 :对老年性白内障囊外摘出并人工晶体植入术的患者 ,出院时的 6 2 6例 80 5眼 (简称出院组 )和 2个月后复诊的 181例 2 10眼 (简称随诊组 )进行检查 ,对裸眼视力 <0 .5者的原因进行统计分析。结果 :裸眼视力 <0 .5者 ,出院组 2 36眼 (2 9.3% ) ,其中因术前原有眼病所致的 19眼 ,因手术致散光、过矫或欠矫等 2 17眼 ;随诊组 43眼 (5 .3% ) ,后囊混浊 2 2眼 ,散光、过矫或欠矫 14眼 ,角膜失代偿 4眼 ,葡萄膜炎 3眼。结论 :老年性白内障囊外摘出并人工晶体植入术后裸眼视力低下的原因 ,主要是手术带来的屈光不正、后发性白内障等。提高手术技巧或选新术式 ,及时随诊 ,是防治视力低下的重要措施 OBJECTIVE: To analyze the causes and prevention and cure of senile cataract extracapsular cataract extraction and intraocular lens implantation. Methods: Sixty-six patients (805 eyes) and 181 patients (210 eyes) who returned to hospital after 2-month follow-up were retrospectively analyzed. Among the patients who underwent extracapsular cataract extraction and intraocular lens implantation, ) Were examined, the uncorrected visual acuity of <0.5 for statistical analysis. Results: The uncorrected visual acuity was less than 0.5, and the discharged group was 36 (2 9.3%). Among them, 19 eyes were caused by preoperative preoperative ophthalmopathy, 217 eyes were due to surgery such as astigmatism, overcorrection or undercorrection; There were 43 eyes (5.3%) in clinic, 22 eyes in posterior capsular opacity, 14 eyes in astigmatism, overcorrection or undercorrection, 4 eyes in corneal decompensation and 3 eyes in uveitis. Conclusion: The causes of low visual acuity after extracapsular cataract extraction and intraocular lens implantation are mainly the refractive errors caused by surgery and the posterior capsular cataract. Improve the surgical skills or choose new surgical techniques, timely follow-up, is an important measure to prevent and treat vision loss
