摘要
本文报道１９３ｎｍ准分子激光角膜切削术（ＰＲＫ）矫正５３６例近视、屈光度为－２．２５～－１５．００Ｄ的９４２眼的疗效，随访２年至３年。术后随访，屈光度在±１．００Ｄ以内者：１年时，低中度组（≤６．００Ｄ）为８６．２％、高度组（＞６．００Ｄ）为６９．６％；２年时，分别为８４．７％和６７．８％；３年时，则分别为９２．３％和８５．７％。术后裸眼视力≥０．５和≥１．０者：１年时，低中度组为９９．３％和８７．６％、高度组为９６．１％和７１．６％；２年时，低中度组为９８．９％和８６．７％、高度组为９５．８％和７０．５％；３年时，低中度组为９６．８％和８８．９％、高度组为１００．０％和８５．７％。术后的角膜上皮下混浊多为０级和１级，极少或无３级及其以上的具有临床意义的角膜上皮下混浊。看来。
The three years results of 193nm excimer laser photorefractive keratectomy(PRK)in 942 sighted eyes of 536 patients are presented.Percentages of ± 1 00D were 86 2% in low to moderate myopia(≤-6 00D)and 69 6% in high and superhigh myopia(>-6 00D or>-9 00D)at 1 yaer after PRK,84 7% and 67 8% at 2 years after PRK,92 3% and 85 7% at 3 years after PRK,respectively.Percentages of uncorrected visual acuity≥0 5 and≥1 0 were 99 3% and 87 6% in low to moderate myopia and 96 1% and 71 6% in high and superhigh myopia at 1 yaer after PRK,98 9% and 86 7%,and 95 8% and 70 5% at 2 years after PRK,96 8% and 88 9%,and 100 0% and 85 7% at 3 years after PRK,respectively,Corneal hazes were few.To date,it appears that PRK is an effctive and safe procedure for correcting myopia.
