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.

Thermal Consequences of Photorefractive Keratectomy

Cornea, 2001
Photorefractive keratectomy (PRK) is still a widely used method for the correction of refractive error despite the advent of laser in situ keratomileusis (LASIK). However, both procedures are associated with significant side effects such as corneal haze and regression.

Corneal Epithelial Thickness Mapping After Photorefractive Keratectomy for Myopia.

Journal of refractive surgery, 2019
PURPOSE To evaluate the longitudinal changes in epithelial thickness after photorefractive keratectomy (PRK) and correlate these with refractive changes. METHODS This prospective study included 52 eyes of 52 candidates for myopic PRK.

Excimer laser photorefractive keratectomy

American Journal of Ophthalmology, 1995
Excimer laser photorefractive keratectomy has been used for the correction of myopia, hyperopia and astigmatism. This laser removes tissue through a process termed photoablative decomposition, in which incident photon energy is sufficient to break molecular bonds.

Epithelial Photorefractive Keratectomy and Corneal Cross-linking for Keratoconus: The Tel-Aviv Protocol.

Journal of refractive surgery, 2019
PURPOSE To present the Tel-Aviv Protocol for patients with progressive keratoconus, which consists of epithelial photorefractive keratectomy (ePRK), and corneal cross-linking (CXL).
