Abstract: An aspheric soft intraocular lens, having an optical power surface, which may have multiple radii portions or aspherical portions, as well as spherical portions, intended to replace the crystalline lens of a patient's eye, in particular after a cataract extraction. Such an aspheric soft lens is molded in a coined mold. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.

Abstract: An intraocular lens (30) having focusing capabilities permitting focusing movement of the lens (30) in response to normal ciliary body (24) movement incident to changes in the distance between the eye and an object under observation is provided. The lens (30) is designed for surgical implantation within the capsule (20) of an eye (10) and includes an optic (32) and an optic positioning element (33) which cooperate to form the lens (30). Accommodation is achieved by relying upon the thickening and thinning of the optic (32) as a result of the normal retracting and contracting of the ciliary body (24) in response to the distance of an object from the viewer.
