Abstract
An intraocular lens for implantation in an eye of a patient includes a multifocal optic and a movement assembly. The optic has maximum add power which is less than the add power required for full near vision for a pseudophakic eye. The movement assembly is coupled to the optic and is adapted to cooperate with the eye of the patient to effect accommodating movement of the optic in the eye. Lens systems including two optics and two movement assemblies are also provided. The intraocular lenses and lens systems are particularly useful when implanted in the eyes of a patient after removal of the natural lenses.
Claims19
An intraocular lens for implantation in an eye of a patient comprising:
- a multifocal optic having a maximum add power which is less than the add power required for full near vision for a pseudophakic eye;
- and
- a movement assembly coupled to the optic and adapted to cooperate with the eye of the patient to effect accommodating movement of the optic in the eye, the movement assembly being positioned relative to the optic so that, with the intraocular lens at rest, the optic vaults anteriorly of the distal end region of the movement assembly.
An ophthalmic lens system for implantation in the eyes of a patient comprising:
- first and second multifocal optics, each of said optics having an add power, the maximum add power of the first optic being less than the add power required for full near vision for a pseudophakic eye, and the first optic provides better visual acuity for objects at infinity than the second optic;
- and
- first and second movement assemblies coupled to the first and second optics, respectively, and adapted to cooperate with the eyes, respectively, of the patient to effect accommodating movement of the first and second optics.
An ophthalmic lens system for implantation in the eyes of a patient comprising:
- first and second multifocal optics, each of said optics having an add power, the maximum add power of the first optic being less than the add power required for full near vision for a pseudophakic eye, the first optic being biased for distance vision and the second optic being biased for intermediate vision;
- and
- first and second movement assemblies coupled to the first and second optics, respectively, and adapted to cooperate with the eyes, respectively, of the patient to effect accommodating movement of the first and second optics.
An ophthalmic lens system for implantation in the eyes of a patient comprising:
- first and second multifocal optics, each of said optics having an add power, the maximum add power of the first optic being less than the add power required for full near vision for a pseudophakic eye, the add power of the second optic is an intermediate add power for intermediate vision for a pseudophakic eye and the best visual acuity provided by the second optic is for objects at intermediate distances;
- and
- first and second movement assemblies coupled to the first and second optics, respectively, and adapted to cooperate with the eyes, respectively, of the patient to effect accommodating movement of the first and second optics.
