Objective: To observe the clinical effect of corneal staining in patients with corneal leucoma. Methods: Restrospective case series study.Thirty eyes of 30 patients (17 males, 13 females) with corneal leucoma who underwent corneal interlamellar staining at Beijing Aier-Intech Eye Hospital from October 2014 to July 2018 were included. The mean age was 31.50±15.66 years. Postoperative follow-up was more than 1 year. All the patients underwent appearance examination, anterior segment examination with a slit lamp, B-scan examination and anterior segment OCT examination preoperatively and postoperatively. The effect of corneal staining, patient satisfaction and the incidence of complications were investigated. Results: The corneal epithelium of all the patients healed completely within 1-3 days after operation. The mean follow-up period was 30.68±18.02 months (range, 12.37-58.10 months). During the postoperative follow-up period, no staining permeation or inflammatory reaction in the anterior chamber occurred. The corneal color and appearance were well maintained in 18 patients (72.0%). Seven patients (28.0%) showed mild corneal color-fading. One patient was treated with enucleation and orbital hydroxyapatite implantation because of eye atrophy and corneal banding degeneration caused by the primary disease at 4 years after operation. The surgeon was satisfied with the improvement of the appearance of all cases; 22 patients (88.0%) were satisfied with the postoperative appearance. No significant complications were observed in all the cases. Conclusions: Corneal interlamellar staining is one of best choices for the treatment of corneal leucoma. It has advantages of quick postoperative recovery, long-standing color staining and good cosmetic effect. The operation is simple and easy to carry out and there is no obvious damage to eye tissues.

目的： 探讨角膜层间染色术的手术特点及对角膜白斑的改善效果。 方法： 回顾性系列病例研究。收集2014年10月至2018年7月于北京爱尔英智眼科医院诊断为角膜白斑并行角膜层间染色术的患者30例（30只眼），其中男性17例，女性13例，年龄（31.50±15.66）岁。所有患者术前及术后均行眼部外观像、裂隙灯显微镜眼前节照相、B超、前节相干光层析成像术检查。观察术后角膜染色效果，调查术者及患者对于手术效果的满意度，观察常见并发症的发生率。 结果： 所有患者均无术中并发症。术后1~3 d角膜上皮均完全愈合。所有患者随访时间为（30.68±18.02）个月（12.37~58.10个月），随访期内均无染色剂渗透进入前房的情况，也未见前房炎性反应发生。18例（72.0%）患者角膜颜色及外观维持良好；7例（28.0%）出现角膜轻微褪色，其中1例在染色术后4年因原发病造成眼球持续萎缩和角膜带状变性，行美容性眼球摘除联合义眼台植入术；本组病例中术者对所有病例的外观改善程度满意，患者满意度调查报告亦显示：22例患者（88.0%）对术后外观基本满意。随访期内所有病例均未见明显并发症发生。 结论： 角膜层间染色术操作简单，对眼部组织损伤小，术后恢复快，治疗角膜白斑效果较好。（中华眼科杂志，2020，56：465-472）.
