Excimer Laser Correction of Astigmatism: Principles and Clinical Results

Chapter

Abstract

Excimer laser photorefractive keratectomy (PRK) was first introduced by Trokel in 1983 to correct myopia [1]. Seiler and coauthors in 1988 proposed this technology to correct astigmatism with T cuts, but the refractive results were not superior to incisional techniques [2]. In 1991, McDonnell published promising clinical results with photoastigmatic refractive keratectomy (PARK) using toric ablation [3]. Since then, more than 20 million excimer laser procedures have been performed, and this technology has become the method of choice to correct both spherical and astigmatic errors. As a result, corneal refractive surgery is the second most frequently performed ocular procedure worldwide, just after cataract surgery.
