Add to ORKGTen subjects were fit with a Boston II and an Opus III gas permeable rigid contact lens, one on each eye. Oxygen permeability measurements were made on the new lenses and at each progress evaluation with a polarographic cell developed by Fatt and St. Helens. The data gathered was analyzed by multiple regression using dummy variables. The statistical analyse showed a decrease in permeability (Dk) that could be explained by surface deposits as a function of patient wearing time
