Abstract
Corneal swelling response was measured for 12 unilateral aphakic patients wearing high-plus hydrogel contact lenses on both eyes. Significantly less corneal edema was measured for aphakic eyes than for the phakic eyes after 2, 4 and 6 h of lens wear. The cornea of the aphakic eye responds differently to a given physiologic challenge than does the cornea of the phakic eye. The O2 permeability previously required of contact lens materials for extended wear may be artificially high for aphakic eyes.
