The effect of fenestrating soft contact lenses on corneal swelling

Nine subjects wore fenestrated and unfenestrated soft contact lenses for 6-hr periods. The lenses worn in the experimental eye were fenestrated with four, 0.80-mm holes, located in the midperipheral region of the lens. THe corneal swelling was monitored with a biomicroscope and pachometer and the fenestrations significantly reduced the corneal swelling compared with the same lens worn prior to fenestration.
