Outflow mechanisms after deep sclerectomy with two different designs of collagen implant in an animal model.

Background: To study experimentally two different shapes of collagen implants (CI) used in deep sclerectomy (DS). The ability to promote drainage vessels, outflow mechanisms, success rates, and biodegradability, were studied prospectively in an animal model.

Materials And Methods: DS was performed in 20 eyes of ten rabbits.
