摘　　要：目的对准分子激光屈光性角膜切削术（ｐｈｏｔｏｒｅｆｒａｃｔｉｖｅｋｅｒａｔｅｃｔｏｍｙ，ＰＲＫ）和准分子激光原位角膜磨镶术（ｌａｓｅｒｉｎｓｉｔｕｋｅｒａｔｏｍｉｌｅｕｓｉｓ，ＬＡＳＩＫ）治疗近视的疗效进行对比研究。方法对术前近视度为－１．５０Ｄ～２０．００Ｄ的患者的６００只眼，按近视度分为三组：中低度近视组（－１．５０Ｄ～－６．００Ｄ）２３４只眼，１９４眼行ＰＲＫ手术，４０眼行ＬＡＳＩＫ手术；高度近视组（－６．２５Ｄ～－１０．００Ｄ）２４９只眼，１０７眼行ＰＲＫ手术，１４２眼行ＬＡＳＩＫ手术；超高度近视组（－１０．２５Ｄ～－２０．００Ｄ）１１７只眼，８眼行ＰＲＫ手术，１０９眼行ＬＡＳＩＫ手术。术后随访观察１２～２３个人。结果术后１２个月，三组患者的屈光度在±１Ｄ以内，行ＰＲＫ手术的患者分别为１００％、７３．８％、５０．０％。ＬＡＳＩＫ手术的患者分别为１００％、８８．７％、７４．３％。屈光度在±０．５０Ｄ以内者，行ＰＲＫ手术者分别为８６．６％、６２．６％、３７．５％，行ＬＡＳＩＫ手术者，分别为８７．５％、８０．３％、５０．５％。术后１２个月，三组的裸眼视力０．５或以上者，行ＰＲＫ手术者分别为１００％、７６．?To compare the effcacy of the correction of myopia between laser in situKeratomilleusis (LASIK)and photo refrective keratomy(PRK).Methods A total of 600 eyes with pre-operative refraction of -1.25～20.00 diopters were studied.According to the refraction,the patients were divided into 3 groups=mild and moderate myopia(-1.25～6.00D)234 eyes,PRK was performed on 194 eyes and LASIK was performed on 40 eyes;high myopia(-6.25～10.00D)249 eyes,PRK107 eyes and LASIK 142 eyes,Severe myopia(-10.25～20.00D)117 eyes,PRK 8 eyes and LASIK 109 eyes,The patients had been followed-up for 12 to 23 months.Results By 12 months postoperatively,in the above groups,100%,73.8%and 50.0% were within ±1D after PRK and 100%,88.7%,74.3% were within ±1D after LASIK respectively.86.6%,62.6%,37.5% were within ±0.5D after PRK and 87.5%,80.3%,50.5% were within0.5D after LASIK respectively.The uncorrected visual a cuity was 0.5 or better in 100%,76.6%,62.5% of the patients through PRK,100%,91.5%,72.5% through LASIK respectively and 1.0 better in 87.6%,63.6%,12.5% of the patients through PRK,96.0%,76.0%,52.3% of the patients throuhg LASIK.Conclusion PRK can be satisfaction for the correction of mild and moderate myopia(≤-6.00D),LASIK is effective for the correction of mild,moderate,high and severe myopia LASIK is more stable and better predictbility than PRK.Howere operaton is more complicated and complication is more severe than PRK.
