A Study Of Residual Astigmatism And Flexure In Fluoroperm 151 lenses Fit 0.50. D Flatter Than "K" On With-The-Rule Toric Corneas.

In recent years the RGP lens market has seen a dramatic increase in the introduction of higher DK materials. These higher DK materials allow for greater oxygen permeability for a given thickness (DK/L) of material. The recent trend in RGP manufacture has been to produce lenses with the maximum DK available. The new materials used to create these RGP lenses can experience a number of lens performance issues such as wettability, dimensional stability, specific gravity, and excessive flexure. This study addresses flexure and residual astigmatism in patients fit with Flouroperm 151 RGP lenses.
