Abstract
Abstract An intraocular lens (11) comprising a deformable optic and first and second fixation members (15,17). Each of the fixation members has a proximal end portion. First and second elongated anchors are (19,21) coupled to the proximal end portions of the fixation members, respectively, and the anchors and the proximal end portions are within peripheral regions of the optic so that the anchors can assist in attaching the fixation members of the optic. The anchors are spaced apart so that the deformable optic can be folded to facilitate insertion of the optic through a relatively small incision into the eye.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
159 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye, said optic having a generally circular periphery; first and second fixation members, each of said fixation members having a proximal end portion; first and second elongated anchors coupled to the proximal end portions of the first and second fixation members, respectively; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye; and at least one of said anchors including an elongated member which forms a segment of an arc and which is coupled to the proximal end portion of the first fixation member, said elongated member extending generally along the periphery of the optic generally coaxial with the optic.
Claim 2
Dependent Claim
159 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye, said optic having a generally circular periphery; first and second fixation members, each of said fixation members having a proximal end portion; first and second elongated anchors coupled to the proximal end portions of the first and second fixation members, respectively; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye; and at least one of said anchors including an elongated member which forms a segment of an arc and which is coupled to the proximal end portion of the first fixation member, said elongated member extending generally along the periphery of the optic generally coaxial with the optic.
Claim 3
Dependent Claim
15 words
An intraocular lens as defined in claim 1 wherein said elongated member includes a filament.
Claim 4
Dependent Claim
36 words
An intraocular lens as defined in any of claims 1 or 2 wherein said one anchor is joined to the first fixation member at a location spaced from the center of the segment of the arc.
Claim 5
Dependent Claim
26 words
An intraocular lens as defined in any of claims 1 to 3 wherein said second anchor includes a filament which forms a segment of an arc.
Claim 6
Dependent Claim
145 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye; first and second fixation members, each of said fixation members having a proximal end portion; first and second anchors coupled to the proximal end portions of the first and second fixation members, respectively, at least one of said anchors extending transversely on both sides of the associated fixation member at the location where said one anchor is coupled to such fixation member; said optic being molded over said anchors and said proximal end portions; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; and said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye.
Claim 7
Dependent Claim
145 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye; first and second fixation members, each of said fixation members having a proximal end portion; first and second anchors coupled to the proximal end portions of the first and second fixation members, respectively, at least one of said anchors extending transversely on both sides of the associated fixation member at the location where said one anchor is coupled to such fixation member; said optic being molded over said anchors and said proximal end portions; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; and said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye.
Claim 8
Dependent Claim
37 words
An intraocular lens as defined in claim 5 wherein said first fixation member has a proximal end and said elongated member extends in both directions on opposite sides of the proximal end of the first fixation member.
Claim 9
Dependent Claim
29 words
An intraocular lens as defined in any of claims 1 to 6 wherein each of said anchors is more rigid than the optic and supports regions of the optic.
Claim 10
Dependent Claim
106 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye; first and second fixation members, each of said fixation members having a proximal end portion; first and second elongated rigid anchors coupled to the proximal end portions of the first and second fixation members, respectively; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; and said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye.
Claim 11
Dependent Claim
106 words
An intraocular lens comprising: an optic which is deformable to facilitate insertion of the optic through an incision into the eye; first and second fixation members, each of said fixation members having a proximal end portion; first and second elongated rigid anchors coupled to the proximal end portions of the first and second fixation members, respectively; said anchors and proximal end portions being within peripheral regions of the optic whereby the anchors assist in attaching the fixation members to the optic; and said anchors being spaced apart whereby the deformable optic can be folded to facilitate insertion of the optic through an incision into the eye.
Claim 12
Dependent Claim
26 words
An intraocular lens as defined in any of claims 1 to 8 wherein at least one of the anchors is integral with the associated fixation member.
Claim 13
Dependent Claim
27 words
An intraocular lens as defined in any one of claims 1 to 8 wherein said one anchor includes a filament staked to the associated proximal end portion.
Claim 14
Dependent Claim
29 words
An intraocular lens as defined in any of claims 1 to 8 wherein at least one of said anchors includes a filament welded to the associated proximal end portion.
