A man aged 26 years presented with complaints of diminution of vision in his right eye for 1 year following a fist injury. He had a history of laser-assisted in situ keratomileusis in both eyes 5 years earlier. On examination, his uncorrected distance visual acuity (UDVA) in the right eye was 1.0 logMAR. Slit-lamp examination of the right eye revealed a superotemporal dislocation of the flap with coexisting epithelial ingrowth encroaching the pupillary area. Due to the presence of long-standing fixed flap folds, a flap amputation was performed along with removal of the epithelial ingrowth using 0.02% mitomycin C as adjunct. Postoperatively, the UDVA was 0.3 logMAR on day 1, which improved to 0.2 logMAR at 1 week. At 1 year, the UDVA was 0.2 logMAR improving to 0.1 logMAR with refraction, with minimal paracentral corneal haze and no signs of corneal ectasia.
一位 26 岁男性，因拳伤后右眼视力下降 1 年就诊。他在 5 年前双眼均接受过激光辅助原位角膜磨镶术。检查发现右眼未矫正远视力（UDVA）为 1.0 logMAR。右眼裂隙灯检查显示上方颞侧角膜瓣脱位，同时伴有侵犯瞳孔区的上皮内长入。由于长期存在固定的瓣皱褶，因此行瓣切除术，并使用 0.02%丝裂霉素 C 辅助切除上皮内长入。术后第 1 天右眼 UDVA 为 0.3 logMAR，术后 1 周提高至 0.2 logMAR。术后 1 年，右眼 UDVA 为 0.2 logMAR，经矫正后提高至 0.1 logMAR，周边角膜混浊最小，无角膜扩张迹象。
