发明名称 Deformable intraocular lens
摘要 A deformable intraocular lens which can be inserted in the eye through a smaller incision by being deformed to have a smaller shape. The lens according to the invention has a deformable optical part which is made of an elastic material, the optical part having a lens portion and a peripheral portion surrounding the lens portion. The peripheral portion is thinner than the center of the lens portion. A plurality of supports are made of a flexible material different from the material of the optical part. Each support has an anchor embedded in the optical part for bonding the support to the optical part. A plurality of reinforcing sections having a thickness larger than the peripheral portion of the optical part are provided at a plurality of positions on the peripheral portion of the optical part or in the proximity thereof. The anchors of the supports are embedded in the reinforcing section. The bonding strength between the optical part and the supports is enchanced and the thickness of the optical part is reduced. Thus, the optical part can be deformed in a smaller shape.
