目的 :探讨准分子激光上皮下角膜磨镶术 (LASEK)治疗准分子激光原位角膜磨镶术 (LASIK)术后屈光欠矫的疗效。方法 :对LASIK术后屈光欠矫的 11例 (2 0只眼 )施行LASEK。结果 :术后 6个月视力和屈光度趋于稳定 ,术后 3个月角膜Haze 0级者 15只眼 ,0 5级者 4只眼 ,1级者 1只眼。术后 6个月 ,裸眼视力≥ 0 6、≥ 1 0者分别为 2 0只眼 (10 0 % )、14只眼 (70 % )。屈光度≤± 1 0 0D者为 19只眼 (95 % )。结论 :LASEK治疗LASIK术后屈光欠矫安全 ,有效。
Objective: To investigate the effect of laser subepithelial keratomileusis (LASEK) on refractive armpits after laser in situ keratomileusis (LASIK). Methods: LASEK was performed in 11 cases (20 eyes) undergoing LASIK. Results: The visual acuity and refraction tended to be stable at 6 months after operation. There were 15 eyes with 0 grade and 0 grade with 3 eyes at 3 months after operation. Six months after operation, the uncorrected visual acuity ≥0 6 and ≥10 were 20 (10%) and 14 eyes (70%), respectively. Diopter ≤ ± 100D were 19 eyes (95%). CONCLUSION: LASEK is safe and effective in treating post-LASIK surgery.
