Description
Orthokeratology, or ortho-K, is a term applied to a method of corneal molding using rigid gas permeable contact lenses to decrease the amount of myopia a patient has, as well as decreasing the amount of astigmatism. orthokeratology technology has been in use since the mid-1950's, but is just beginning to get more notoriety due to the popularity today of other corneal molding techniques ( e.g. radial keratonomy and laser molding ) . In this study, we looked at a specific portion of the ortho-K program/technique, the retainer lens, in the hopes of determining which wearing schedule, day wear or night wear, is superior. We also hope to determine just how well the retainer lens works, especially as it relates to the varying degrees of myopia.
