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。术后未发现
Corneal astigmatism after cataract extraction directly affects postoperative corrected visual acuity, which has been the subject of study by many scholars over a hundred years. With the growing use of intraocular lens, postoperative corneal astigmatism is more and more important. Now the Shenzhen Municipal People’s Hospital in recent years, microscopic and non-microscopic cataract extraction of postoperative corneal astigmatism were analyzed as follows: Materials and Methods Microsurgical 34 cases of 35 eyes, 46 cases of non-microsurgery 51 eyes, a total of 80 cases 86 eyes. Age 54 ~ 88 years old, average 71 years old. All eyesight less than 0.1 senile cataract, were made for silicone capsule removal surgery. All eyes without cataracts before wearing glasses, and normal vision. Preoperative Placido disc examination of the cornea, corneal concentric ring shape are all round, found no obvious distortion or oval. Not found after surgery
