目的为评价准分子激光角膜切削术矫正近视的结果。方法应用ＳＶＳＡＰＥＸ型准分子激光治疗仪对１５０例（２６０只眼）近视患者进行准分子激光角膜切削术，并对随诊的患者进行观察。分别于术后１０ｄ，１、２、３、６、１２月就视力、屈光度、眼压、角膜透明度、角膜地形图进行随访评估。１５０例（２６０只眼）近视患者术前等值球镜屈光度为－１２５～－１０００Ｄ（－４６７±１６３Ｄ），散光０～２００Ｄ（－０３３±０４５Ｄ）；按屈光度分为两组：Ａ组（－１２５～－５９０Ｄ），Ｂ组（－６００～－１０００Ｄ）。结果Ａ组术后第１０ｄ，有６８９％裸眼视力达到矫正视力，１月、３月、６月和１２月分别为９０％、９６％、９５％和９４％。Ｂ组术后第１０ｄ，有３５９％裸眼视力达到矫正视力，１月、３月、６月和１２月分别为８３％、８７％、８６％和８４％。１ａ时，裸眼视力≥０５、０８、１０者，在全组分别为９９３％、９５６％、９１３％；在Ａ组分别为１００％、９８８％、９４７％；在Ｂ组分别为９５５％、９０２％、６８５％。其中，术后全组最佳矫正视力下降１行或２行者分别为６６％和０％。全组仅３只眼（０６４％）除外，均为? Objective To evaluate the results of excimer laser keratomileusis correction of myopia. Methods Excimer laser keratotomy was performed on 150 cases (260 eyes) of myopia with SVSAPEX excimer laser. The patients were followed up. Visual acuity, refraction, intraocular pressure, corneal transparency, and corneal topography were assessed at 10 days, 1,2,2,3,6 and 12 months respectively. In 150 cases (260 eyes) myopia patients with preoperative spherical equivalent refraction was -1.25 ~ -1000D (-467 ± 163D), astigmatism 0 ~ 200D (-033 ± 0  45D). According to diopter, the patients were divided into two groups: group A (-125 ~ -590D) and group B (-600 ~ -1000D). Results Group A had corrected visual acuity of 68.9% at the 10th day after operation. The corrected visual acuity was 90%, 96%, 95% and 94% in January, March, June and December respectively. On the 10th day after operation, 35.9% of uncorrected visual acuity was corrected visual acuity in group B, 83%, 87%, 86% and 84% in January, March, June and December respectively. 1a, the visual acuity of the naked eye ≥ 0.5,0  8,1  0, in the whole group were 993%, 956%, 913%; in the A group were 100%, 988 %, 947%; in group B, 955%, 902%, 685% respectively. Among them, postoperative best corrected visual acuity decreased by 1 line or 2 lines were 6  6% and 0%. The whole group except for 3 eyes (064%), are?
