摘要
目的 :了解准分子激光角膜切削术 (PRK)与准分子激光角膜原位磨镶术 (LASIK)治疗低、中、高度近视半年疗效的比较。方法 :对PRK 116只眼屈光度为 0 .75D～ 13 .0 0D与LASIK 113只眼屈光度为 1.0 0D～ 17.0 0D术后半年患者的视力、角膜屈光度进行随访观察。结果 :裸眼视力达到术前矫正视力者 ,PRK :Ⅰ组 ( 0 .75～ 3 .0 0D)为 10 0 % ,Ⅱ组 ( 3 .0 0D～ 6.0 0D)为 99.1% ,Ⅲ组(> 6.0 0D)为 88% ;LASIK :Ⅰ组为 10 0 % ,Ⅱ组为 88.2 4% ,Ⅲ组为 93 .5 5 %。术后半年等值球镜 ,PRK :Ⅰ组为 0 .2 5D ,Ⅱ组为 + 0 .14D ,Ⅲ组为 + 0 .79D ;LASIK :Ⅰ组为 0 .0 0D ,Ⅱ组为 + 0 .2 5D ,Ⅲ组为 0 .0 4D。结论 :PRK治疗低、中度近视疗效肯定 ,LASIK治疗低、中、高度近视的疗效迅速。
Objective: To compare the effects of photorefrective keratectomy (PRK) and keratomileusis (LASIK) in situ for the correction of low, moderate and high myopia.Methods:The follow up for more than half a year of 116 myopia eyes ( 0.75 D～13.00 D) after PRK and 113 myopia eyes( 1.00 D～ 17.00 D) after LASIK was analyzed.Patients were divided into three groups: group Ⅰ( 0.75 D～ 13.00 D) group Ⅱ( 3.00 D～ 6.00 D) group Ⅲ(> 6.00 D). Results:The rates of postoperative visual acuity were 100% in group Ⅰ,99.1% in group Ⅱ and 88% in group Ⅲ.While in LASIK,100% in group Ⅰ,88.24% in group Ⅱ and,93.55% in group Ⅲ. The mean spherical equiualent changes of PRK were 0.25 D in group Ⅰ,+0.14 D in group Ⅱ, and +0.79 D in group Ⅲ. While in LASIK,0.00D in gruop Ⅰ,+0.25D in group Ⅱ, and 0.04 D in group Ⅲ.Conclusion:PRK for low and moderate myopia is effective while LASIK for low,moderate and high myopia is more effective.
