Laser research has rapidly expanded in the area of corneal sculpting in the past few years. Lasers with specific wavelengths in the ultraviolet and infrared ranges are best suited for ablating corneal tissue without disturbing clarity of the surrounding matrix. This is essential in laser refractive procedures. The excimer laser is an ultraviolet dimer laser with a wavelength of 193 nm. Excimer laser research has progressed rapidly and FDA-approved clinical trials are presently underway. This paper covers various aspects of the excimer's history, qualities of excimer laser ablation, mechanisms of damage, various laser delivery systems, and FDA-approved clinical trial results.
在过去几年中，激光研究在角膜塑形领域迅速发展。紫外线和红外线范围内具有特定波长的激光最适合于消融角膜组织，同时又不会干扰周围基质的清晰度。这在激光屈光手术中至关重要。准分子激光是一种波长为193纳米的紫外线二聚体激光。准分子激光研究进展迅速，目前美国食品药品监督管理局（FDA）批准的临床试验正在进行中。本文涵盖了准分子激光的历史、准分子激光消融的特性、损伤机制、各种激光传输系统以及FDA批准的临床试验结果等各个方面。
