摘要
目的：研究老年性白内障患者的屈光状态。方法：对８６例老年性白内障患者（１７２只眼）的裸眼视力、矫正视力、白内障类型和分期以及相互关系进行了统计分析。结果：老年性白内障的初发期和中期随着年龄的增加视力呈逐渐下降趋势，但经过矫正，视力可以大幅度提高，其中皮质性与混合性中以远视为主、核性中多为近视。结论：老年性白内障初发期和中期的视力下降多是由晶状体的屈光指数改变及晶状体的弹性降低和睫状肌调节功能下降所致。
OBJECTIVE: To study the dioptric situation of the patients with senile cataract METHODS: The visual acuity, the corrected visual acuity, the cataract types and different phases of 86 patients with cataract (172 eyes), were examined and the relationships among them were analyzed statistically RESULTS: The visual acuity of the patients with cataract decreases gradually as the aging in the early and middle phase, but their corrected visual acuity can be much better There was more hyperopia in the cortex and mixture cataract, there was mainly myopia in the nuclear cataract among these cataracts CONCLUSIONS: It reveals that the visual acuity decreasing of the early and middle phase cataracts is mainly caused by the changing of lens dioptric index and the decreasing of lens elasticity and ciliary muscles function
