title: Chemical effects of alkali on polymethylmethacrylate intraocular lenses.
abstract: Polymethylmethacrylate intraocular lenses were left in 10% NaOH or 10% KOH for various periods of time. Contact angles were unaltered and electron spectroscopy for chemical analysis was unchanged. This concentration of alkali does not appear to chemically change the lens surface during the study period.
