Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
30 words
An ocular implant prosthesis having a transparent lenticule, a carrier comprising preserved tissue adapted for attachment to an eye, and a bioadhesive polyphenolic protein bonding the carrier to the lenticule.
Claim 2
Dependent Claim
30 words
An ocular implant prosthesis having a transparent lenticule, a carrier comprising preserved tissue adapted for attachment to an eye, and a bioadhesive polyphenolic protein bonding the carrier to the lenticule.
Claim 3
Dependent Claim
19 words
The prosthesis of claim 1 wherein the polyphenolic protein is of the type derived from the mussel genus Mytilus.
Claim 4
Dependent Claim
55 words
An ocular implant prosthesis having a transparent lenticule made of biologically acceptable material, a carrier comprising an annular ring of preserved, denatured biological tissue, the outer periphery of said annular ring being adapted for attachment to the eye wall, and a bioadhesive polyphenolic protein bonding the inner circumferential surface of the carrier to the lenticule.
Claim 5
Dependent Claim
55 words
An ocular implant prosthesis having a transparent lenticule made of biologically acceptable material, a carrier comprising an annular ring of preserved, denatured biological tissue, the outer periphery of said annular ring being adapted for attachment to the eye wall, and a bioadhesive polyphenolic protein bonding the inner circumferential surface of the carrier to the lenticule.
Claim 6
Independent Claim
85 words
A method of surgically repairing the cornea comprising the steps of: (a) removing at least a partial, generally circular thickness of the eye wall; (b) attaching to an ocular prosthesis having a carrier of preserved, denatured biological tissue a transparent lenticule by forming a radially inwardly extending flange on the carrier and inserting the flange into a complimentary groove in the outer periphery of the lenticule; and (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
Claim 7
Independent Claim
85 words
A method of surgically repairing the cornea comprising the steps of: (a) removing at least a partial, generally circular thickness of the eye wall; (b) attaching to an ocular prosthesis having a carrier of preserved, denatured biological tissue a transparent lenticule by forming a radially inwardly extending flange on the carrier and inserting the flange into a complimentary groove in the outer periphery of the lenticule; and (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
Claim 8
Independent Claim
71 words
A method of surgically repairing the cornea comprising the steps of: (a) removing at least a partial, generally circular thickness of the eye wall; and (b) bonding a transparent lenticule to a carrier of preserved, denatured biological tissue of an ocular prosthesis by applying a thin layer of bioadhesive polyphenolic protein therebetween; and (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
Claim 9
Independent Claim
71 words
A method of surgically repairing the cornea comprising the steps of: (a) removing at least a partial, generally circular thickness of the eye wall; and (b) bonding a transparent lenticule to a carrier of preserved, denatured biological tissue of an ocular prosthesis by applying a thin layer of bioadhesive polyphenolic protein therebetween; and (c) surgically attaching the ocular prosthesis to the eye wall, covering the area from which tissue was removed.
