We present our clinical strategy to treat corneal diseases with the excimer laser. Nine eyes with recurrent erosion after trauma, three eyes with band keratopathy, and one eye with secondary crystalline deposits and a leukoma adherens after perforating injury underwent excimer laser phototherapeutic keratectomy (PTK). The patients with recurrent erosion had at least six episodes in the 12 months, the other patients suffered from severe pain. The recurrent erosions were treated with 15 pulses (193 nm, 180 mJ/cm2, 10 Hz) after removing the epithelium. There was only one new episode within 6 months after treatment in a patient who failed to follow the postoperative therapeutic regimen. In the patients with band keratopathy we removed the calcium deposits mechanically and then used masking fluids to obtain a smooth surface. The crystalline deposits in the patient with leukoma adherens could be removed but recurred after 4 months; the patient still suffered from glare.
我们展示了用准分子激光治疗角膜疾病的临床策略。9例外伤后复发性角膜糜烂患者、3例带状角膜病变患者以及1例穿孔伤后继发晶状体沉着和粘连性白斑的患者接受了准分子激光角膜切削术（PTK）。复发性角膜糜烂患者在12个月内至少发作6次，其他患者疼痛剧烈。去除上皮后，用15个脉冲（193nm，180mJ/cm²，10Hz）治疗复发性角膜糜烂。1例未遵循术后治疗方案的患者在治疗后6个月内仅出现1次新发作。对于带状角膜病变患者，我们机械去除钙沉着，然后使用掩蔽液以获得光滑表面。粘连性白斑患者的晶状体沉着可以去除，但4个月后复发；该患者仍有眩光症状。
