The authors report on the Phototherapeutic 193nm-Excimer Laser Keratectomy (PTK) for the treatment of superficial corneal opacities.
In two cases with corneal opacities after contact lens wearing and after therapy resistant keratoconjunctivitis epidemica respectively the treatment strategy is presented. The epithelium and the corneal opacities are removed mechanically as far as possible. Then the Excimer laser smoothing with masking fluids of different viscosity is performed.
In both patients the visual acuity improved from 1/50 and 0.16 respectively to 0.7. Both eyes had an hyperopic shift. The patients were without pain within a follow-up period of 8 months after treatment.
The phototherapeutical use of the 193nm Excimer laser to treat superficial corneal opacities can be regarded as a real alternative to conventional surgical techniques.
作者报告了用于治疗浅层角膜混浊的193nm准分子激光角膜切削术（PTK）。
分别介绍了两例因佩戴隐形眼镜后和治疗抵抗性流行性角结膜炎后出现角膜混浊的治疗策略。尽可能机械性地去除上皮和角膜混浊。然后使用不同粘度的掩蔽液进行准分子激光平滑处理。
两名患者的视力分别从1/50和0.16提高到了0.7。两只眼睛均出现了远视性移位。在治疗后的8个月随访期内，患者均无疼痛。
193nm准分子激光用于治疗浅层角膜混浊的光治疗方法可被视为传统手术技术的一种切实可行的替代方法。
