A method is described of improving adhesion of an ocular implant to corneal tissue by forming an implant adhesive layer on the ocular implant, the implant adhesive layer having greater adhesive strength than a rest of the implant or by forming a corneal adhesive layer on a posterior surface of a posterior portion of the corneal tissue, the corneal adhesive layer having greater adhesive strength than a rest of the corneal tissue.

SYSTEMS AND METHODS FOR CORNEAL TRANSPLANTS

Corneal transplant procedures may involve suturing an implant of healthy corneal tissue to a recipient cornea. The sutures may cause unwanted deformation of the corneal implant and the recipient cornea. A supporting structure may be embedded into the corneal implant to enhance the stability of the corneal implant and the recipient cornea and to reduce the likelihood of unwanted deformation when the corneal implant is sutured to the recipient cornea. According to one embodiment, a corneal implant includes donor corneal tissue extracted from a donor cornea. The donor corneal tissue includes an interior channel formed at a depth below an anterior surface. The corneal implant includes a supporting structure formed from non-tissue material and positioned in the channel.

A storage/delivery device includes a first wall defining a well configured to receive a corneal tissue. The storage/delivery device includes a second wall configured to be positioned over the first wall and to seal the well. The second wall includes a recess configured to extend into the well to define a chamber between the first wall and the second wall. The chamber is configured to hold the corneal tissue when the second wall seals the well. A system may include the storage/delivery device above and a measurement system configured to measure the corneal tissue disposed in the well. In one example embodiment, the measurement system is an optical coherence tomography (OCT) system. In another example embodiment, the measurement system is a second-harmonic generation (SHG) or third-harmonic generation (THG) microscopy system.
