Abstract

Abstract Attachment means for an artificial intraocular lens system for implantation in the eye comprises a pair of capsule clips laterally extending from the edge of the lens and lying within or parallel to the plane of the lens, and at least a single clip diametrically opposed to the pair of clips. The members of the pair of capsule clips are resiliently biased into co-planar alignment or biased against separation. The members of the pair of capsule clips may have serrations for more secure engagement of the capsule.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 203 words
An artificial intraocular lens system constructed and arranged to be implanted within an opening in the capsular bag of the normal lens of an eye immediately adjacent the iris of the eye to supplant or replace the normal lens of the eye, comprising an optical lens portion formed in circular, convex configuration of biologically tolerable, optically suited material so as to have an optical axis, and attachment means extending generally radially outwardly from said lens portion at spaced positions about its periphery for engaging parts of the capsular bag surrounding said opening so as to secure said lens portion in the opening, said attachment means including, at at least one position about said periphery, two cooperating clip members which extend generally radially outwardly and are axially separatable so as to receive and secure therebetween a part of the capsular bag surrounding said opening, such that the respective clip members bear against inner and outer surface portions of said capsular bag to assist in securing said lens portion in position in said opening, said clip members being of resilient material and projecting radially beyond the periphery of said lens portion, said clip members being normally coplanar with one clip member lying inside the other.
Claim 2
Dependent Claim 203 words
An artificial intraocular lens system constructed and arranged to be implanted within an opening in the capsular bag of the normal lens of an eye immediately adjacent the iris of the eye to supplant or replace the normal lens of the eye, comprising an optical lens portion formed in circular, convex configuration of biologically tolerable, optically suited material so as to have an optical axis, and attachment means extending generally radially outwardly from said lens portion at spaced positions about its periphery for engaging parts of the capsular bag surrounding said opening so as to secure said lens portion in the opening, said attachment means including, at at least one position about said periphery, two cooperating clip members which extend generally radially outwardly and are axially separatable so as to receive and secure therebetween a part of the capsular bag surrounding said opening, such that the respective clip members bear against inner and outer surface portions of said capsular bag to assist in securing said lens portion in position in said opening, said clip members being of resilient material and projecting radially beyond the periphery of said lens portion, said clip members being normally coplanar with one clip member lying inside the other.
Claim 3
Dependent Claim 47 words
A lens system as claimed in claim 1 wherein at least one other generally radially extending clip member is located diametrically opposite said two cooperating clip members so as to extend into said opening and bear against at least the inner surface portion of the capsular bag.
Claim 4
Dependent Claim 30 words
A lens system as claimed in claim 1 wherein said clip members are loops of resilient material mounted so as to project radially beyond the periphery of said lens portion.
Claim 5
Dependent Claim 35 words
A lens system as claimed in claim 3 wherein said loops are joined to said lens portion by generally axially extending members such that the radial portions of said loops lie behind the lens portion.
Claim 6
Independent Claim 248 words
A method of implanting an artificial intraocular lens within an eye to supplant or replace the normal lens of the eye, said lens comprising an optical lens portion formed in circular, convex configuration of biologically tolerable, optically suited material so as to have an optical axis, and attachment means extending generally radially outwardly from said lens portion at spaced positions about its periphery for engaging parts of the capsular bag surrounding said opening so as to secure said lens portion in the opening, said attachment means including, at at least one position about said periphery, two cooperating clip members which extend generally radially outwardly and are axially separatable so as to receive and secure therebetween a part of the capsular bag surrounding said opening, such that the respective clip members can bear against inner and outer surface portions of the capsular bag to assist in securing the lens portion in position in said opening, said method comprising surgically forming an opening in the anterior wall of the capsular bag of the normal lens adjacent the iris and removing material from within said capsular bag, placing said artificial intraocular lens in said opening with said clip members axially separated so as to receive therebetween a part of the anterior wall of the capsular bag surrounding said opening, and causing said clip members to move axially toward each other to embrace said wall part independently of said iris and assist in securing said artificial lens in position in said opening.
Claim 7
Independent Claim 248 words
A method of implanting an artificial intraocular lens within an eye to supplant or replace the normal lens of the eye, said lens comprising an optical lens portion formed in circular, convex configuration of biologically tolerable, optically suited material so as to have an optical axis, and attachment means extending generally radially outwardly from said lens portion at spaced positions about its periphery for engaging parts of the capsular bag surrounding said opening so as to secure said lens portion in the opening, said attachment means including, at at least one position about said periphery, two cooperating clip members which extend generally radially outwardly and are axially separatable so as to receive and secure therebetween a part of the capsular bag surrounding said opening, such that the respective clip members can bear against inner and outer surface portions of the capsular bag to assist in securing the lens portion in position in said opening, said method comprising surgically forming an opening in the anterior wall of the capsular bag of the normal lens adjacent the iris and removing material from within said capsular bag, placing said artificial intraocular lens in said opening with said clip members axially separated so as to receive therebetween a part of the anterior wall of the capsular bag surrounding said opening, and causing said clip members to move axially toward each other to embrace said wall part independently of said iris and assist in securing said artificial lens in position in said opening.
