Methods and lenticules for modifying the cornea

A method of providing an eye with an artificial member comprising:

• preparing said eye for receipt of said artificial member by removing the epithelium from a portion of the cornea to expose the Bowman's layer of the cornea;
• placing an uncured collagen as a precurser of said artificial member on said eye;
• and
• curing said collagen to render it stable and to bond to said eye as said artificial member.

A method of providing an eye with a modified cornea comprising:

• preparing said eye for modification of said cornea by removing the epithelium from a portion of the cornea to expose the Bowman's layer of the cornea;
• placing a collagen precurser of a modification to said cornea on a portion of said cornea;
• and
• inducing said precurser to cure and to adhere to said cornea to provide said cornea with a modified configuration.

A method of providing a smooth surface for an initially rough-surfaced cornea comprising:

• preparing said cornea to receive a collagen precurser of a lenticule by removing the epithelium from a portion of the cornea to expose the Bowman's layer of the cornea;
• depositing viscous collagen on said cornea;
• and
• curing said collagen while allowing the shape of said collagen to be controlled by ambient forces.

A method of attaching a collagen lenticule precurser to an eye comprising:

• preparing said eye by removing the epithelium from a portion of the cornea to expose the Bowman's layer of the cornea;
• providing a bead of viscous collagen along the periphery of a preformed lenticule;
• positioning said lenticule in a desired location on said eye;
• and
• curing said viscous collagen and any incompletely cured collagen at the posterior surface of said lenticule to bond said lenticule to said eye and to provide a smooth transition between the lenticule and the Bowman's layer of said eye.
