The present application is directed to a method of performing ocular surgery using biomaterial from placenta and/or umbilical cord, wherein the biomaterial is contacted with a tissue of the eye, or tissue surrounding the eye, affected by the surgery. The biomaterial is also used in surgery performed to repair trauma to the eye, whether deliberately or accidentally caused. The eye surgery can be, e.g., glaucoma surgery, oculoplastic surgery, cataract surgery, vitreo-retinal surgery, refractive surgery, retinal surgery, eye muscle surgery, or the like.
