The effect of peripherally fenestrated contact lenses on corneal edema. 1977

M G Harris, and D J Barreto, and M S Matthews

To determine the effect of peripherally fenestrated contact lenses on central corneal edema, 6 subjects (12 eyes) wore steeply fitted lenses of identical dimensions but with various numbers of 0.1-mm diameter peripheral fenestrations for 3-hr periods. At the end of the wearing periods, thickening, steepening, and central clouding of the cornea were generally reduced as the number of fenestrations was increased. However, 20 fenestrations were required before the edema was reduced to a clinically acceptable level.

D003261 Contact Lenses Lenses designed to be worn on the front surface of the eyeball. (UMDNS, 1999) Lenses, Contact,Contact Lens,Lens, Contact
D003315 Cornea The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
