Abstract
An intraocular lens system to be implanted in the posterior chamber of an eye, the system comprises a lens having an optical axis and at least two haptics extending from the circumference of the lens. The two haptics each includes one or more teeth located on their periphery.
Claims21
An intraocular lens system to be implanted and securely anchored in a posterior chamber of an eye, the system comprising
- a lens having an optical axis;
- and
- a haptic system associated with said lens such that said lens can be retained in the eye said haptic system being securely implantable in an interior surface of that portion of a scleral wall that forms the outermost border of a ciliary sulcus and which scleral wall is comprised of tough connective tissue of the eye, said haptic system when so implanted in the eye firmly attaches said lens in an operative position
- said haptic system comprising
- at least two haptics, each haptic having an outer periphery and extending outwardly from a circumference of said lens, and at least three, spaced apart, penetrating members, each penetrating member having a tip portion and at least one penetrating member located on each of said haptic outer periphery, each penetrating member extending in a generally radially outward direction from said optical axis, said haptic and penetrating member having a shape and strength such that said penetrating member tip portion can penetrate the ciliary sulcus scleral wall so that said lens system is anchored in the posterior chamber of the eye.

17-18. (canceled)
20-22. (canceled)
A haptic system for an intraocular lens system which is to be implanted and securely anchored in a ciliary sulcus scleral wall in posterior chamber of an eye having an optical axis, said haptic system comprising
- a base which can retain a lens that has an optical axis;
- and
- at least two haptics extending radially outwardly from a circumference of said base, said two haptics together including at least three radially outwardly extending penetrating members, each haptic and penetrating member having a shape and strength so said penetrating member can penetrate the ciliary sulcus scleral wall and remain embedded therein so that said lens system is securely anchored in the eye independent of support from an eye posterior capsule and from an eye iris, whereby said haptic system when so implanted in the eye said lens is rigidly fixed in an operative position.
A method of implanting an intraocular lens in an eye, the method comprising,
- inserting a haptic system having a first side and a second side into a posterior chamber of an eye having an optical axis, said haptic system comprised of at least a first and a second haptic on respective haptic system sides, each haptic having an outer periphery and at least one penetrating member extending outwardly from said outer periphery, the penetrating member having a shape and strength so that said penetrating member can penetrate a ciliary sulcus scleral wall of the eye and remain embedded therein;
- positioning the haptic system such that at least said first haptic contacts the ciliary sulcus scleral wall of the eye;
- manipulating the haptic system such that at least a penetrating member on said first haptic penetrates the ciliary sulcus scleral wall and is securely embedded therein so as to securely anchor said haptic in the ciliary sulcus of the eye;
- positioning the haptic system further such that said other haptic if not already in contact with the ciliary sulcus scleral wall, contacts the ciliary sulcus scleral wall;
- and
- manipulating the haptic system such that a penetrating member on said second haptic if not already penetrating the ciliary sulcus scleral wall penetrates the ciliary sulcus scleral wall and is securely embedded therein so as to securely anchor said haptic system in the posterior chamber of the eye.
