Abstract
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.
Claims26
A method for preparing an implant for attachment to a posterior surface of the cornea, comprising:
- providing a corneal copolymer implant comprising the monomer 2-hydroxyethyl methacrylate and having an anterior surface and a posterior surface, and
- exposing at least the anterior surface of the implant to a treatment that improves adhesion between the implant and the cornea.
A method for making an ocular implant which comprises providing a dome-shaped implant comprising PMMA or Poly HEMA and applying laser energy to at least an anterior surface of said implant to configured said implant for attachment to a posterior surface of the cornea, said anterior surface being an adhesive surface for attaching the implant to the posterior surface of the cornea.
A method for making an ocular implant which comprises providing a transparent dome-shaped implant having an anterior surface and a posterior surface, the implant comprising PMMA or Poly HEMA and treating at least one surface of the implant to improve adhesion between the implant and a posterior surface of a cornea.
A method comprising:
- improving adhesion of an external surface of an ocular implant which is made of a polymeric material by making a change to said external surface that changes a chemical feature of said polymeric material which improves adhesion of said external surface to a posterior surface of a cornea.
