Abstract 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.
