Phototherapeutic keratectomy (PTK) with the excimer laser has been shown to be effective in removing anterior corneal pathology and smoothing surface irregularities. Blocking agents are important in PTK. The techniques we present seek to balance therapeutic effect and refractive error change. Successful PTK depends on thorough preoperative assessment and attention to intraoperative detail. Clinical research has demonstrated that the excimer laser is an effective tool, not only for correcting myopic refractive errors, but also for treating various types of anterior corneal pathology. We present our PTK techniques that reflect recent refinements.
准分子激光光治疗性角膜切削术（PTK）已被证明在去除角膜前部病变和平滑表面不规则方面是有效的。阻滞剂在PTK中很重要。我们介绍的技术旨在平衡治疗效果和屈光不正的变化。成功的PTK取决于全面的术前评估和对术中细节的关注。临床研究表明，准分子激光不仅是矫正近视屈光不正的有效工具，也是治疗各种类型角膜前部病变的有效工具。我们介绍了反映近期改进的PTK技术。
