title: Contact lens surface damage related to cases and case removal techniques.
abstract: Surface damage incurred as a result of removing polymethyl methacrylate (PMMA) contact lenses form various contact lens carrying cases was monitored by photographic techniques. As compared to the controls, the experimental lenses showed consistent increases in surface damage, particularly if they were removed by a sliding (dragging) motion along the contours of the case.
