Abstract
A biodegradable lens-shaped patch useful for healing and treatment of ocular conditions is disclosed. The patch is formed from a biodegradable carrier which carries amniotic extract and/or placental extract. The lens-shaped patch may be shaped in the form of a conventional contact lens and it is applied to a corneal surface to enhance healing thereof. After a certain period of time, the patch dissolves on its own and it need not be removed from the eye by a clinician. In an embodiment, the patch includes a clear central section that may be refractory, and a biodegradable peripheral section.
