摘要
目的探讨准分子激光原位角膜磨镶术 (L aser in situ keratom ileusis,L ASIK)治疗高、中、低度近视的可预测性、稳定性及安全性。方法利用 SCMD公司生产的微型角膜刀及 Com pak- 2 0 0型准分子激光机对 2 93例 5 6 5眼近视行矫治手术 ,根据屈光度进行分组 , 组 :- 1.5 0～ - 5 .75 D12 0眼 ; 组 :- 6 .0 0～ - 9.75 D2 30眼 ; 组 :- 10 .0 0～- 14.75 D 148眼 ; 组 :- 15 .0 0～ - 2 6 .0 0 D 6 7眼 ;术后随访 6 m o以上。结果术后 6 mo时各组裸眼视力分别为 :1.15± 0 .2 0、0 .92± 0 .2 2、0 .6 9± 0 .2 4、0 .44± 0 .2 2 ;其中≥ 1.0者分别为 91.7%、5 6 .7%、18.0 %、0 % ;≥ 0 .5者分别为 10 0 %、94.6 %、85 .8%、47.7% ,基本达到术前矫正视力 ;术后各组屈光度稳定 ,6 mo时分别为 - 0 .14D± 0 .6 1D、- 0 .43D±1.2 0 D、- 0 .5 7D± 1.47D、- 1.79D± 2 .5 7D,无严重并发症发生。结论 L ASIK对矫治近视是有效且安全的 ,但应注意其潜在并发症。
Objective To study the predictability, stability and safety of laser in situ keratomileusis (LASIK) for myopia Methods Five hundred and Sixty five eyes ( 293 patients ) were treated with the SCMD corneal shaper and laser sight Compak 200 excimer laser and followed up for more than 6 months These eyes were divided into 4 groups according to the degrees of myopia: Group Ⅰ:-1 50～-5 75D,120 eyes; Group Ⅱ:-6 00～-9 75D,230 eyes; Group Ⅲ:-10 00～-14 75D,148 eyes and croup Ⅳ: -15 00 ～-26 00D,67 eyes Results Six months post operatively, mean uncorrected visual acuity of each group was 1 15±0 20, 0 92±0 22, 0 69±0 24 and 0 44±0 22 respectively; The uncorrected visual acuity of 0 5 or better was 100%, 94 6%, 85 8% and 47 7% respectively; And 1 0 or better was 91 7%, 56 7%, 18 0% , 0% respectively Mean spherical equivalent of each group was -0 14D±0 61D, -0 43D±1 20D, -0 57D ±1 47D and -1 79D±2 57D respectively There were no serious complications Conclusion LASIK is an effective and safe method for reducing myopia But the potential complications should be noticed
