Several embodiments disclosed herein relate to compositions and methods for treating or repairing damage to ocular tissue. In particular, several embodiments relate to patches that interact, e.g., by way of an adhesive, with damaged retinal tissue to repair or mend a hole, tear or detachment of the retina from underlying ocular tissue. Still additional embodiments relate to self-assembling patches.
