| 摘要 |
The present invention is directed to an accommodating intraocular lens for implantation into a generally circular inner surface of an eye, comprising: (a) an optic (34); (b) at least two haptics (36) extending from opposite edges of the optic and having inner ends joined to the optic, and adapted to engage the generally circular inner surface of the eye for holding the lens in the eye; (c) each of the haptics including an outer portion (36b) with a surface shaped to engage the generally circular inner surface of the eye, at least part of said outer surface adapted to extend beyond the diameter- of the generally circular inner surface of the eye when said outer portion is in its unstressed state, said outer portion being flexible and for not conforming to the generally circular inner surface of the eye until subjected to compressive forces so that the outer surface can conform generally to the shape of the inner surface of the eye when subjected to said compression forces upon implantation, said outer portion being shaped to be encapsulated by the inner surface of the eye so as to hold the haptics in place relative to the inner surface of the eye when the inner surface of the eye expands and contracts; and (d) the haptics being flexible along at least a portion of their respective lengths and adapted to move the optic anteriorly and/or posteriorly relative to the haptics in response to forces imparted to the lens through ciliary muscle contraction and relaxation. |
