Clinical evaluation of continuous-wear hydrophilic lenses.

Twenty patients who had previously not worn contact lenses were fitted with a thin, continuous-wear hydrophilic contact lens in the right eye for 12 weeks. Seventeen patients completed the study and tolerated the lenses well. Some patients developed changes in corneal thickness, corneal curvature, and refraction, and some changes in visual acuity were reversed when the lens was removed. Many developed lens opacities that did not interfere with vision. We encountered no infections or corneal neovascularization in this study.
