CTL Tinted Hydrogels And Corneo Refractive Changes.

The purpose of this study is to evaluate the extent of corneal and refractive changes in normals due to the daily wear of hydrophilic contact lenses tinted by the CTL Permatint
Process (TM) . Sporadic cases of keratoconoidlike changes have been associated with these clear pupil tinted lenses. One such case is included. Refitting this patient with a clear
hydrogel con tact lens after a short period of mandatory spectacle wear reversed this corneal abnormality adequately and efficiently.
