目的探讨准分子激光原位角膜磨镶术(laser in situ keratomileusis,LASIK)后角膜瓣皱褶的原因和处理。方法对LASIK术后13例膜瓣皱褶的原因和处理进行回顾性分析。将术后角膜瓣皱褶分类为小皱褶和大皱褶指导治疗,小皱褶以观察为主,大皱褶采用去上皮水化角膜瓣加戴接触镜法。结果术后大多小皱褶可随时间推移自动消失。大皱褶经处理所有患者裸眼视力均达到术前最佳矫正视力,角膜透明,未见明显皱褶,角膜瓣位置正常,无上皮植入。结论角膜瓣皱褶可根据皱褶轻重分类指导治疗方法,大多可治愈并恢复良好的视力。
Objective To investigate the causes and treatment of corneal flap ruffling after laser in situ keratomileusis (LASIK). Methods Retrospective analysis was made on the causes and management of flap ruffling in 13 cases after LASIK. The postoperative corneal flap folds were classified as small folds and large folds to guide the treatment, small folds to observe the main wrinkles with epithelial hydration flap plus contact lens method. Results Most postoperative folds can disappear automatically over time. Large folds of all patients treated with uncorrected visual acuity reached the best corrected visual acuity before surgery, corneal transparency, no significant folds, corneal flap position normal, no epithelial implantation. Conclusion Corneal flap folds can be classified according to the severity of wrinkles guide treatment, most of them can be cured and restore good vision.
