老年性白内障屈光状态临床分析

A Clinical Analysis of Dioptric Situation in the Patients with Senile Cataract

目的探讨老年性白内障类型与其屈光状态关系。方法对102例(204眼)老年性白内障以裂隙灯检查散瞳后晶状体混浊状况,应用自动验光仪对小瞳孔及散瞳眼行电脑验光,并对矫正前后视力及屈光状态进行比较。结果老年性白内障类型与屈光不正种类有着显著的关系(P<0.001),皮质性和混合性多为远视及远视散光,核性以近视及近视散光为主,初中期白内障矫正视力有明显提高。结论老年性白内障其晶状体混浊引起的屈光状态改变是导致初中期白内障患者视力下降的主要原因,早期患者矫正视力可明显提高。

Purpose To study the relationship between the cataract types and the dioptric situation of the patients with senile cataract.Methods The lens opacity of the 102 patients with cataract(204 eyes)under mydriatic condition was examined using slit lamp.The computer optometry was conducted.Then,the visual acuity,the corrected visual acuity and reflection condition of them were compared.Results The relationship between the types of the senile cataract and refractive error was statistically correlated(P<0.001).There was more hyperopia and hypermetropic astigmatism in the cortex and mixture cataract,there was mainly myopia and myopic astigmatism in the nuclear cataract among these cataracts.The corrected visual acuity of the patients with cataract in the early and middle phase would be much better.Condusion It reveals that the visual acuity decreasing in the early and middle phase cataracts is mainly caused by the changing of opacity lens dioptric situation.The visual acuity of the early phase can be corrected obviously.
