目的 研究准分子激光角膜原位磨镶术 (LASIK)治疗近视的安全性和有效性。方法 回顾性分析LASIK治疗 463眼高度近视的并发症及预后。结果 术后裸眼视力与术前相比 ,75 2 9%达到或超过术前最佳矫正视力。术中并发症的发生率为不完全角膜瓣占 0 86% ,游离角膜瓣占 0 43 % ,角膜瓣偏位占 0 2 2 % ,角膜缘出血占 7 3 %。术后并发症的发生率为瓣下异物 2 8% ,屈光欠矫或过矫 9 8% ,层间角膜炎症 0 43 % ,皮质类固醇性高眼压 0 43 % ,角膜上皮植入 0 65 %。结论 准分子激光角膜原位磨镶术治疗高度近视安全有效 ,但需完善的设备和丰富的临床经验。
Objective To study the safety and efficacy of excimer laser in situ keratomileusis (LASIK) in the treatment of myopia. Methods The complications and prognosis of 463 eyes with high myopia treated with LASIK were retrospectively analyzed. Results The postoperative uncorrected visual acuity was 75.29% or better than the preoperative best corrected visual acuity. The incidence of intraoperative complications was 86% with incomplete corneal flap, 0 43% with free flap, 0 2 2% with corneal flap, and 73% with limbal bleeding. The incidence of postoperative complications was 28% of the subvalvular foreign bodies, undercorrection or overcorrection of 9 8%, inter-layer keratitis 0 43%, corticosteroid-induced intraocular hypertension 0 43%, corneal epithelial implantation 0 65 %. Conclusions Excimer laser in situ keratomileusis is safe and effective in treating high myopia, but requires perfect equipment and rich clinical experience.
