摘要
目的探讨和评估微型角膜刀准分子激光角膜上皮瓣下磨镶术(epipolis laser in situ keratomileusis,Epi-LASIK)与准分子激光角膜上皮瓣下磨镶术(laser epithelial keratomileusis,LASEK)治疗中高度近视的安全性和有效性。方法 Epi-LASIk 组31例(59眼)和同期 LASEK39例(75眼).Epi-K 微型角膜上皮刀(平推型)进行 Epi-LASIK 术(Mofia Epi 刀须负压45 s 才达到规定指标)。LASEK 采用20%乙醇浸润20～30 s,临床观察两者术后症状、视力、角膜上皮瓣愈合特点及视觉质量等。结果 Epi-LASIK 组术后6个月裸眼视力达术前矫正视力占92.35%,LASEK 组术后6个月裸眼视力达术前矫正视力占93.83%。主要并发症有术后部分少许角膜上皮下雾状混浊(Haze)形成及继发高眼压。两组术后对比敏感度提高,出现眩光差异无显著性意义结论 Epi-LASIK 及 LASEK 术均可安全,有效的矫治中高度近视。两者的长期疗效有待观察。
Purpose To compare the efficacy and safety between epipolis laser in situ keratomileusis （Epi-LASIK） and laser epithelial keratomileusis （LASEK） for the treatment of moderate to high myopia. Methods This retrospective analysis comprised 59 eyes that had Epi-LASIK,75 eyes that had LASEK for moderate to high myopia with a follow up of six months. Results In the Epi-LASIK group, best spectable corrected visual acuity （BSCVA） was achieved to preoperative corrected visual acuity in 92.35% at 6 months after surgery; no corneal Haze was found. In the LASEK group, Uncorrected visual acuity （UCVA） was achieved to preoperative corrected visual acuity in 93.83% at 6 months after surgery. Main comphcations included high intraocular pressure and mild corneal Haze formation. Conclusion Both of Epi-LASIK and LASEK are safe and effective rehactive surgery for moderate to high myopia.
