Abstract
A supplemental intraocular lenses may be attached to conventional primary intraocular lenses using annular wrap-around clamps or adhesive. New primary intraocular lens configurations have pockets for accommodating relatively small, supplemental intraocular lenses therein.
Claims25
A supplemental intraocular lens for attachment to a primary intraocular lens, comprising:
- an optic portion having at least one optical power and an optic-portion periphery;
- a peripheral zone surrounding at least 20% of the optic-portion periphery, the peripheral zone having substantially no optical power and having a reduced thickness relative to a thickness of the optic-portion periphery.
A supplemental intraocular lens for attachment to a primary intraocular lens, comprising:
- an optic portion having at least one optical power and contacting a first primary intraocular-lens face;
- an additional peripheral zone surrounding at least a part of the optic portion, the additional peripheral zone having substantially no optical power and being adapted to contact a second primary intraocular-lens face located substantially opposite the first primary intraocular-lens face.
A supplemental intraocular lens comprising an optic portion adapted for use in an eye and having at least one optical power, the supplemental intraocular lens including no structure effective to independently fix the position of the supplemental intraocular lens in the eye, the optic portion being sized and adapted to fit within a primary intraocular lens to thereby provide supplemental vision correction to the eye in which the primary intraocular lens is located.
A supplemental intraocular lens comprising an optic portion having at least one optical power, the optic portion sized and adapted to fit within a pocket of a primary intraocular lens to thereby provide a supplemental vision correction to the primary intraocular lens.
A primary intraocular lens having at least one optical power, and having a pocket for accommodating a supplemental intraocular lens to thereby modify the optical power of the primary intraocular lens.
A supplemental intraocular lens adapted to be attached to a primary intraocular lens within an optically-powered area equal to a reference area, comprising:
- a supplemental-intraocular-lens body having an optically-powered face with an area less than the reference area.
A supplemental intraocular lens adapted to be attached within an optically-powered portion of a primary intraocular lens, the optically-powered portion having a curvilinear periphery equal to a reference distance, comprising:
- a supplemental-intraocular-lens body having a curvilinear periphery less than the reference distance.
