Laser subepithelial keratomileusis for treatment of myopia and astigmatism

目的 探讨准分子激光上皮瓣下角膜磨镶术 (LaserSubepithelialKeratomileusis ,LASEK)治疗近视散光的疗效。方法 2 2 5例 42 3眼行LASEK术 ,术前裸眼视力 (UncorrectedVisualAcuity ,UCVA) 0 0 1～ 0 8,平均 0 2± 0 16,最佳矫正视力 (BestCorrectedVisualAcuity ,BCVA )0 5～ 1 5 ,平均 1 14± 0 18。术前近视度数 -0 2 5～ -10 75D ,平均 -4 2 2± -1 88D ,散光度数 -0 2 5～ -5 0 0D ,平均 -1 0 4± -0 74D。随访 3～ 12月。结果 术后裸眼视力 0 2～ 1 5 ,平均 1 0 6± 0 18。术后 3 89眼 ( 92 % )有轻度不适。术后 2 1眼出现haze ,0 5级 15眼 ,1 0级 4眼 ,2 0级 2眼。结论 LASEK兼具了PRK和LASIK的优点 ,无严重并发症 ,手术预测性好 ,是一种安全。

Objective To evaluate the safety and efficacy of laser subepithelial keratomileusis(LASEK) for the treatment of myopia and astigmatism.Methods LASEK weas performed in 423 eyes of 225 patients with myopia and astigmatism.The preoperative uncorrected visual acuity(UCVA) were 0 01～0 8,mean 0 2±0 16.The preoperative best corrected visual acuity(BCVA) were 0 5～1 5,mean 1 14±0 18.The mean preoperative sphere and cylinder were -4 22±-1 88D(range -0 25～-10 75D)and -1 04±-0 74D(range -0 25～-5 00D).Followed up 3～12 months.Results The postoperative UCVA were 0 2～1 5,mean 1 06±0 18.Haze of 15 eyes was at 0 5 grade,4 eyes at 1 grade,2 eyes at 2 grade.There was no serious complications.Conclusions LASEK was safety and effective in treating myopia and astigmatism.
