Abstract
Abstract A process for making a corneal inlay and implanting the inlay in the human eye, the latter comprising the steps of preparing a lens blank; shaping the blank by laser milling or the like; preparing a recess in the cornea of the patient, the recess being adapted to receiving the shaped inlay whereby the exterior surface of the inlay lies flush with the Bowman's layer; and bonding the inlay to the recess by suturing, laser welding, gluing or other appropriate means.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
87 words
A process for replacing a portion of the corneal tissue of the human eye, the process comprising the steps of: (a) preparing a lens blank; (b) shaping the blank into a desired lens configuration; (c) preparing a recess in said eye, said recess being in the corneal tissue and being adapted to receive said shaped blank whereby the outer surface of said blank lies flush with Bowman's membrane; and (d) bonding the shaped blank into said recess by laser fusing said shaped blank to said corneal tissue.
Claim 2
Dependent Claim
87 words
A process for replacing a portion of the corneal tissue of the human eye, the process comprising the steps of: (a) preparing a lens blank; (b) shaping the blank into a desired lens configuration; (c) preparing a recess in said eye, said recess being in the corneal tissue and being adapted to receive said shaped blank whereby the outer surface of said blank lies flush with Bowman's membrane; and (d) bonding the shaped blank into said recess by laser fusing said shaped blank to said corneal tissue.
Claim 3
Dependent Claim
82 words
A process for replacing a portion of the corneal tissue of the human eye, the process comprising the steps of: (a) preparing a lens blank; (b) shaping the blank into a desired lens configuration by laser milling said blank; (c) preparing a recess in said eye, said recess being in the corneal tissue and being adapted to receive said shaped blank whereby the outer surface of said blank lies flush with Bowman's membrane; and (d) bonding the shaped blank into said recess.
Claim 4
Dependent Claim
82 words
A process for replacing a portion of the corneal tissue of the human eye, the process comprising the steps of: (a) preparing a lens blank; (b) shaping the blank into a desired lens configuration by laser milling said blank; (c) preparing a recess in said eye, said recess being in the corneal tissue and being adapted to receive said shaped blank whereby the outer surface of said blank lies flush with Bowman's membrane; and (d) bonding the shaped blank into said recess.
Claim 5
Dependent Claim
83 words
A process for replacing a portion of the corneal tissue of the humam eye, the process comprising the steps of: (a) preparing a lens blank; (b) shaping the blank into a desired lens configuration; (c) preparing a recess in said eye by laser milling said corneal tissue, said recess being in the corneal tissue and being adapted to receive said shaped blank whereby the outer surface of said blank lies flush with Bowman's membrane; and (d) bonding the shaped blank into said recess.
Claim 6
Dependent Claim
