Abstract
An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens has a first baseline diopter power for distance vision correction and the second ophthalmic lens has a second baseline diopter power for other than distance vision correction. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient or has natural lenses or following removal of the natural lenses.
Claims38
An ophthalmic lens system for improving the vision of a patient comprising:
- a first multifocal ophthalmic lens for use with one eye of a patient, and having a first baseline diopter power for distance vision correction;
- a second multifocal ophthalmic lens for use with the other eye of the patient, and having a second baseline diopter power for other than distance vision correction and a maximum power less than the add power required for full near vision correction for the patient;
- and
- each of said first and second lenses being adapted for implantation in an eye or to be disposed on or in a cornea of an eye.
An ophthalmic lens system for improving the vision of a patient comprising:
- a first multifocal ophthalmic lens for use with one eye of a patient, the first lens having a power including a first baseline diopter power for distance vision correction for the patient;
- a second multifocal ophthalmic lens for use with the other eye of the patient, the second lens having a second baseline diopter power other than for distance vision correction, a power including an intermediate add power for intermediate vision correction for the patient and a maximum power which is less than the full add power required for near vision correction for the patient;
- the first lens providing better visual acuity for objects at infinity than the second lens;
- and
- each of the first and second lenses being adapted for implantation in an eye or to be disposed on or in a cornea of an eye.
An ophthalmic lens system for improving the vision of a patient comprising:
- a first multifocal lens for use with one eye of the patient, the first lens having a first optical axis and a first baseline diopter power for distance vision correction, the power of the first lens changes along a first power curve in a radially outward direction from the first optical axis;
- a second multifocal lens for use with the other eye of the patient, the second lens having a second optical axis and a second baseline diopter power for other than distance vision correction, the power of the second lens changes along a second power curve in a radially outward direction from the second optical axis;
- the first and second power curves being substantially similar;
- and
- each of the first and second lenses being adapted for implantation in an eye or to be disposed on or in a cornea of an eye.
An ophthalmic lens system for improving the vision of a patient comprising:
- a first multifocal ophthalmic lens for use with one eye of a patient, the first lens having a first baseline diopter power and being biased for distance vision;
- a second multifocal ophthalmic lens for use with the other eye of the patient, the second lens having a second baseline diopter power different from the first baseline diopter power and a maximum power less than the add power required for full near vision correction for the patient, and being biased for intermediate vision;
- and
- each of the first and second lenses being adapted for implantation in an eye or to be disposed on or in the cornea.
