First Claim
Patent Images
1. An accommodative lens system, comprising:
- (a) a first lens with a negatively powered optic body adapted to be located substantially in the posterior chamber of a human eye;
said first lens configured so as not to be fixed in a specific position along the optic axis, but rather to remain in the central position in the pupil and to shift along the optic axis; and
(b) a second lens with a positively powered optic body configured to be implanted inside the capsular bag.

Abstract
An accommodative intraocular lens system for treating presbyopic is disclosed. The system includes a first lens having negative optic power adapted for placement in the posterior chamber of the eye and capable of moving forward and back along the optic axis; and a second lens having a positive optic power which is implanted within the capsular bag. The second lens can be the natural crystalline lens of the eye. The position of the first lens, forward or back relative to the second lens, focuses the eye for seeing distant or close-in objects.

19. A method for implanting an accommodative lens system in the eye of a patient, comprising the steps of:
-
(a) making an incision in the eye; (b) implanting through said incision a second lens with a positively powered optic body, implanted inside the capsular bag of the patient; and (c) implanting through said incision a first lens with a negatively powered optic body, substantially in the posterior chamber of the eye, such that it is not fixed in a specific position in the eye, but rather remains in a central position in the pupil and is capable of shifting along the optic axis of the eye. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method for implanting an accommodative lens system in the eye of a patient retaining their natural crystalline lens, comprising the steps of:
-
(a) making an incision in the eye; and (b) implanting through said incision a phakic lens with a negatively powered optic body, substantially in the posterior chamber of the eye, such that it is not fixed in a specific position in the eye, but rather remains in a central position in the pupil and is capable of shifting along the optic axis of the eye. - View Dependent Claims (33, 34, 35, 36, 37, 38)
