发明名称 Accomodative intraocular lens
摘要 An accommodative intraocular lens having a soft deformable resilient inner lens portion or core with an exposed anterior inner optic surface and exposed posterior optic surface, the surfaces responsively becoming simultaneously optically steeper and moving axially away from each other. The exposed anterior and posterior surfaces of the inner lens portions may be spherically shaped or aspherically shaped and the shape of the outer lens portion may be spherically or aspherically shaped.

主权项 1. An accommodative intraocular lens having an anterior side and a posterior side, comprising: an outer lens portion having an anterior outer optic surface and a posterior outer optic surface, the outer lens portion having a continuous outer peripheral edge and a continuous inner annular wall portion disposed concentrically within said continuous outer peripheral edge so as to define a central hole within said outer lens portion such that said outer lens portion comprises a continuous annulus, said outer lens portion being fabricated from a predetermined material; and an inner lens portion, separate and distinct from said outer lens portion, having an exposed anterior inner optic surface, an exposed posterior inner optic surface, and disposed within said central hole of said outer lens portion with an outer peripheral lens wall portion of said inner lens portion bonded to said inner annular wall portion of said outer lens portion, the inner lens portion being formed from a soft deformable resilient material which is softer than said predetermined material from which said outer lens portion is formed; wherein radially inner compression forces disposed upon said outer peripheral edge of the outer lens portion will tend to radially inwardly compress the outer peripheral lens wall portion of said inner lens portion such that the exposed anterior inner optic surface and the exposed posterior optic surface will each be deformed axially outwardly away from each other.
