Abstract

The purpose of this study was to observe the corneal and refractive changes that occur when a PMMA wearer is refit with a highly gas permeable contact lens. Pachometry data indicated that the corneal thickness of most subjects increased after having worn the lenses for two weeks. The corneal curvatures of nearly all subjects steepened and showed an increase in cylinder. Increases in myopia, which correlated with the steepened corneal curvatures, occurred after two weeks of Paraperm wear. These results could differ if the subjects were followed for a longer period of time.
