准分子激光角膜切削术后2年结果分析

The Result Analysis After Excimer Laser Photorefractive Keratectomy Following As 2 Years

本文对－１０．００Ｄ以下的１２３７眼准分子激光角膜切削术前及术后２年病人的裸眼视力，矫正视力，屈光情况及角膜屈光力，角膜透明性做了对比分析，结果显示轻、中、重三组病人的正视率分别为７８．５％、７６．３％、４５．６％，过矫率分别为２１．５％、２１．６％、３．２％，欠矫率分别为０、２．１％、４２．４％，证明此手术是目前治疗近视的一种安全，有效。

eyes were retrospectively analyzed 2 years after photorefractive Keretectomy.The myopic eyes were devided into 3 groups according to the amount of myopia.Preoperative refraction was under 10 00D for the eyes involved.The uncorrected visual accuity,best corrected visual accuity,refraction and corneal refractive power and corneal clearity were reviewed and the rates of emmetropia,over corrected and undercorrected myopia were 78 5%,76 3%,45 6%;21 5%,21 6%,3 2%;0;2 1%,42 4% for slight,mild and severe myopic eyes respectively 2 years after surgey.It can be concluded that Photorefractive keretectomy was an effective,safe,predictable method for treatment of myopia.
