为探讨玻璃体手术后白内障发生率及其影响因素，回顾性地调查近５年的玻璃体手术病人。观察指标有性别、眼别、年龄、病程、病因、视力、术式、手术次数、并发症及玻璃体状态等。晶体混浊判定采用ＬＯＣＳⅡ系统；采用Ｂａｙｅｓ逐步判别法进行统计学处理。追踪观察２９～６５个月（平均４３．４±９．４个月），玻璃体手术后白内障发生率为９．９２％，其中核硬化占６９．２３％，后囊下混浊占３０．７７％。影响因素有年龄、病因、病程及术后高眼压（Ｆ＝２时，判对率９３．４８％，Ｐ＝０．００００）。结论：在较高年龄组（平均４８．５６岁），晶体混浊与病因及年龄相关，主要表现为核硬化；在较低年龄组（平均２６．２５岁），多与病程较长（１１．２５个月）、病变广泛有关，表现为囊下混浊。术后高眼压对两者均有影响
To investigate the incidence of cataract and its influencing factors after vitreous surgery, retrospective investigation of vitreous surgery patients in recent 5 years. Observed indicators of gender, eye, age, duration, etiology, visual acuity, surgical procedures, the number of operations, complications and vitreous state. The opacity of crystal was determined by LOCSⅡ system. The Bayesian discriminant method was used for statistical analysis. The follow-up ranged from 29 to 65 months (average 43.4 ± 9.4 months). The incidence of cataract after vitreous surgery was 9.92%, of which nuclear sclerosis accounted for 69.23%, posterior capsule opacification accounted for 30.77% . Factors affecting age, etiology, duration of disease and postoperative IOP (F = 2, the sentence rate of 93.48%, P = 0.0000). CONCLUSIONS: In the higher age group (mean 48.56 years), the opacity of the ophthalmoscope is related to the etiology and age, and is mainly manifested as nuclear sclerosis. In the lower age group (mean 26.25 years), the longer and longer the ophthalmopathy. 25 months), extensive disease, manifested as subaccular opacity. Postoperative IOP have an impact on both
