Abstract
An intraocular lens exhibits handedness and comprises a refractive portion and haptics extending out from the refractive portion. The lens is designed to minimize errors in centration and tilt that are statistically different in the case of implantation in right and left eyes, respectively. The haptics and/or the refractive portion of the lens is radially asymmetric in such a manner that, except for structural characteristics attributable to refractive prescription, a lens intended for implantation in a left eye is a mirror image of a lens intended for implantation in a right eye. The haptics engage the eye in any manner desired by the surgeon, and the design is such that the optical zone of the refractive portion is then centered on the pupil and the optical axis of the refractive portion coincides with, or has some other prescribed relation to, the visual axis of the eye.
