The potential applications of an ophthalmic excimer laser at 193 nm include its use as a precise trephine in keratoplasty procedures. In a series of 20 human autopsy and 40 pig cadaver eyes the histological and ultrastructural results of donor and recipient trephination and full-thickness corneal grafting using new mask systems were evaluated. In comparison with other beam delivery systems the "open mask system" allows the performance of excimer laser trephinations with reproducible wound configuration and geometry, with easy handling and high reliability. This technique enables the surgeon to surmount the mechanical limitations of cutting direction and makes non-circular trephinations possible.
波长为193nm的眼科准分子激光的潜在应用包括在角膜移植手术中用作精确的环钻。在一系列20例人类尸眼和40例猪尸体眼中，评估了使用新型掩膜系统进行供体和受体环钻以及全层角膜移植的组织学和超微结构结果。与其他光束传输系统相比，“开放式掩膜系统”能够进行准分子激光环钻，其伤口形态和几何形状具有可重复性，操作简便且可靠性高。这项技术使外科医生能够克服切割方向的机械限制，并使非圆形环钻成为可能。
