Systems for amniotic tissue ocular surface resurfacing and methods therefor

A method of preparing a corneal surface of an eye for an ocular surgery, the method comprising:

• developing a native tackiness of the corneal surface by removing moisture from the corneal surface, without applying a saline or a rehydrating solution to the corneal surface, such that a corneal epithelium of the corneal surface develops a tacky consistency;
• laying an amniotic tissue body onto the corneal surface such that the amniotic tissue body conforms to and fills one or more surface irregularities of the corneal surface so as to present a smooth ocular surface, the amniotic tissue body comprising a non-handed construction that presents equivalent amniotic tissue to the corneal surface independent of which face of the amniotic tissue body is placed against the corneal surface, and the amniotic tissue body being laid onto the corneal surface without orienting a stromal side of the amniotic tissue body toward the corneal surface and without debriding or scraping the corneal surface or the corneal epithelium, such that the corneal epithelium is preserved beneath the amniotic tissue body;
• retaining the amniotic tissue body against the corneal surface, at least in part by the tacky consistency of the corneal epithelium or by a securing element placed over the amniotic tissue body;
• allowing the amniotic tissue body to dwell upon the corneal surface over a dwell period during which a regenerative or anti-inflammatory factor of the amniotic tissue body is delivered to the corneal surface;
• and
• obtaining a biometric measurement or a corneal mapping from the smooth ocular surface presented by the amniotic tissue body for the ocular surgery.
