摘要
白内障摘出术后角膜散光直接影响术后矫正视力,是百多年来许多学者研究的课题。随着人工晶体应用的日益广泛,术后角膜散光显得越来越重要。现将深圳市人民医院近年来显微与非显微白内障囊摘摘出术后角膜散光的情况分析如下: 资料和方法显微手术34例35眼,非显微手术46例51眼,共80例86眼。年龄54～88岁,平均71岁。全为视力低于0.1的老年性白内障,均作硅胶囊内摘出术。所有患眼在患白内障前均未戴眼镜,且视力正常。术前用Placido氏盘检查角膜,角膜同心环形态均为正圆形,未发现明显扭曲或椭圆形。
The corneal astigmatism on 35eyes of microsurgery and 51 eyes ofnon-microsurgery after cataract intracapsular extraction have beenstudied. At three months postoperation the average degrees ofastigma-tism was 0.96±0.40 Din microsurgery and was 2.11±0.92 D in non-micro-surgery. There were significant difference beteen the two groups in theaverage degrees of astigmatism (p<0.005). The corrective vision by sp-herical lens combined with cylindric lens was betwter than by simplespherical lens in non-microsurgery (p<0.05), but it was not significantdifference in microsurgery (p>0.05). The astigmatism against the rulewas 88.6% in microsurgery and 90.2% in non-microsurgery, two groupshaving not significant defference (P>0.005).
