白内障手术666眼特点及复明质量分析

Analysis on the Characteristics of Cataracts and the Effect of Phacoemulsification on 666 Eyes

目的了解老年及其他类型白内障患者的临床特点及复明质量。方法统计和分析602例(666眼)白内障手术患者的情况,指标包括白内障患者的年龄、性别构成比、成因构成比、超声乳化术患者年龄与白内障晶体核硬度的关系、超声乳化手术患者核硬度与手术时间的关系、白内障超声乳化手术患眼术后视力情况、3组手术(一片式、折叠式、注入式)手术前后平均视力比较、超高度近视眼的白内障及高龄白内障患者的潜视力预测和实际视力符合率等。结果接受白内障手术的患者以60～80岁居多,占61.9%;类型以老年性白内障为主,占65%;Ⅳ级核白内障患者以70岁以上组居多分别为46.6%(60～70岁)和49.6%(70～80岁)。手术脱盲率达到100%,脱残率达到92.8%。结论本文统计的白内障患者的特点及发病规律与我国相关文献报道基本相同,高龄组白内障手术效果并不因其年龄大而受影响,其复明质量与一般白内障患者相似,视觉复明质量的高低与手术者的操作技巧及并发症的发生有密切关系。

Objective To evaluate the characteristics of age-related and other cataracts;and the functional recovery after phacoemulsification with intraocular lens（IOL）.Methods six hundred and sixty six eyes in 602 patients who underwent phacoemulsification were included in this study.The parameters included：the age,gender and the etiological factors of cataract;the relationship among the degree of hardness of lens＇ nucleus,the age and the operation time;pre-and post-operative best corrected visual acuity（VA）of patients implanted 3 different kinds of IOL;and the correlation between VA and high myopia,and the age.Results The patients aged 60~80 years old constituted 61.9% of all patients received phacoemulsification.The data showed that age-related cataract was the main type of cataract（65%）.The cataract of Ⅳ grade mainly occurred in patients more than 70 years old.The ratio was 46.6% and 49.6% in the groups of 60~70 years old and 70~80 years old,respectively.The VA was well improved post-operation.Postoperative VA（≥0.3）was composed of 92.8%.Conclusions This study is consistent with the previous reports.Effect of phacoemulsification is not affected by the age.Old patients can gain good VA as others.The effect of phacoemulsification is affected by the operation skills and the complications.
