This study was undertaken to determine the results of modification on the Physical fit and physiological effects of Polycon contact lenses. The differences between the clinical performances of unmodified Polycons and modified Polycons were investigated by employing eleven parameters. Modified Polycons performed superiorly (in a statistically significant fashion) in the areas of movement and centration, patient appearance, wearing time, and patient comfort. No statistically significant difference occurred in the areas of injection, staining, edema, post-refraction, and post-k's.
