METHOD OF PRODUCING A REFRACTIVE OCULAR LENS |
摘要 |
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. |
