Phototherapeutic keratectomy (PTK) is an acceptable technique to treat recurrent erosion syndrome. Its disadvantage is postoperative pain. We present a modified technique to reduce the immediate pain from removal of the epithelium after PTK. Nine patients with recurrent erosion syndrome had PTK with epithelial reflap (similar to laser-assisted subepithelial keratectomy) and contact lens application. The follow-up was 6 months. No patient reported severe postoperative pain. Three of 9 patients reported mild pain during the first 24 hours postoperatively. The best spectacle-corrected visual acuity was 0.40 to 0.63 logMAR on the first postoperative day and 0.80 to 1.00 logMAR after a week. No patient developed recurrent erosion.
光治疗性角膜切削术（PTK）是治疗复发性角膜糜烂综合征的一种可接受的技术。其缺点是术后疼痛。我们提出一种改良技术以减轻PTK术后上皮移除引起的即时疼痛。9例复发性角膜糜烂综合征患者接受了带上皮瓣的PTK（类似于激光辅助上皮下角膜磨镶术）并应用了隐形眼镜。随访时间为6个月。没有患者报告严重的术后疼痛。9例患者中有3例在术后24小时内报告有轻微疼痛。术后第一天最佳矫正视力为0.40至0.63 logMAR，一周后为0.80至1.00 logMAR。没有患者发生复发性角膜糜烂。
