Abstract
An ocular lens has a refractive optics structure formed from a polyisobutylene-based material and a glassy segment that is non-reactive to ocular fluid and that maintains in vivo transparency for a substantial time period. The material has a central elastomeric polyolefinic block and thermoplastic end blocks (such as a triblock polymer backbone comprising polystyrene-polyisobutylene-polystyrene). The material is preferably flexible such that the refractive optics structure can be folded upon itself and introduced through a small scleral incision. The lens device includes an optic portion and preferably either an annular haptic element or one or more haptic elements adapted to rest within a capsular bag formed by a surgical procedure. A portion of the lens device may be loaded with at least one therapeutic agent that interferes with proliferation of the epithelial cells of the eye to protect against PCO.

55. An ocular lens device for use in an ocular environment comprising:
a deformable refractive optics structure that is configurable into an arrangement where the refractive optics structure is folded or rolled upon itself, said refractive optics structure having a radius of curvature that varies according to accommodating forces applied by the ciliary muscles of the ocular environment. - View Dependent Claims (56, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88)
