Comparison between Myoring® and 355ºKERATACx® in Management of Keratoconus

Abstract

Kis that progressive, non-inflammatory, K bilateral (but usually asymmetrical),degenerative disease of the cornea, characterized by paraxial stromal thinning that leads to corneal surface distortion, eventually leading to Visual loss occurs primarily from irregular astigmatism and myopia and secondarily from corneal scarring. Intracorneal implants had been proposed over the years as a possible easier way for managing keratoconus having a favorable influence on the course of the disease, and thus decreasing (or even eliminating) the necessity of transplantation, the purpose of corneal implants is to flatten the central part of the cornea help regularizing it, which in its result may lead to an improvement of the patient‘s visual acuity and relief of most of patient’s complaints. Corneal implants are flexible rings, circular or hemi-circular in shape and made of polymethyl-methacrylate that are implanted deep within the corneal stroma. They affect refraction in the eye by physically altering its shape and flattening the steep part of the cornea or the cone thus reducing visual distortions.
