title: Validation of a model describing soft lens movement as a function of lens specification.
abstract: The authors fitted 12 subjects with 30% water-content, soft contact lenses. The sagittal depth of the lenses was varied in five steps while diameter was held constant. In a second study, diameter was varied from 12 to 14 mm in five steps. Regression analysis was used to analyze the data. Lens movement can be decreased by increasing lens thickness, reducing lens diameter, or flattening the base curve of the lens.
