[Clinical experiences with a therapeutic collagen contact lens].

In 43 eyes of 40 patients, the therapeutic effects of a self-dissolving hydrophilic collagen contact lens were investigated. Epithelial defects of any source, lamellar perforating corneal injuries, and trophic sterile corneal ulcers were defined as indications for the use of the lens. Collagen contact lenses were applied with biodegradation times of 6, 24, and 72 h. All patients tolerated the lens well, and no adverse reactions to the collagen material were observed. In all diseases where the lens was applied, re-epithelialization was found to be relatively fast.
