Photorefractive Keratectomy and Cataract

Survey of Ophthalmology, 1997
Fifty male albino rabbits were studied. Ten animals served as controls. Forty animals were prepared to receive photorefractive keratectomy (PRK), including anesthesia, scraping of the corneal epithelial cells, etc. Twenty of these animals then received PRK with energy delivered by excimer laser (pulse rate = 20 Hz, fluence 250 mJ/cm2; number of pulses =

Optics for photorefractive keratectomy

Journal of Cataract and Refractive Surgery, 1993
Matrix calculations are applied to Gaussian optics in the study of myopic correction by photorefractive keratectomy. The Colliac matrix formula determines the postoperative anterior curvature radius of the treated cornea. It also calculates the maximal depth of the removed corneal tissue and the ablation zone diameter needed to achieve emmetropia.
