Abstract
An intraocular lens (10, 60, 100) adapted to be fixated to the periphery of either the iris or an opening in the capsular bag has an annular ring (12) including an upper flange (14), a lower flange (16), and an interconnecting inner wall (18). Disposed within the annular (12) is a substantially circular lens (26). Alternatively, the intraocular lens includes a substantially circular lens (62) with a substantially U-shaped channel (64) extending inwardly along the perimeter of circular lens (62).
Claims29
An intraocular lens adapted to receive the periphery of the iris of an eye or an opening in the capsular bag of an eye comprising:
- an annular ring having an outer upper flange, an outer lower flange, and an inner wall interconnecting said flanges, said flanges being spaced to receive therebetween the periphery of the iris or an opening in the capsular bag of an eye;
- and
- a lens operatively interconnected to said inner wall, and wherein said lens is a thin membrane having a plurality of concentric circular grooves formed therein, said concentric rings forming a plurality of concentric annular prisms.
The intraocular lens of claim further comprising a reinforcement ring attached to said annular ring to reduce the collapsibility of said intraocular lens, said reinforcement ring being manufactured from a material having a higher stiffness than the material from which said annular ring is manufactured.
An intraocular lens comprising:
- an integral annular ring having an outer upper flange, an outer lower flange, and an inner wall interconnecting said flanges, said flanges being spaced to receive therebetween the periphery of the iris or an opening in the capsular bag of an eye;
- a thin, optically clear membrane lens having a plurality of concentric circular grooves formed therein, said concentric circular grooves forming a plurality of annular prisms, said membrane lens having a perimeter formed with said inner wall;
- and
- a reinforcement ring attached to said integral annular ring to maintain said lens in a planar orientation in use.
An intraocular lens adapted to receive the periphery of the iris of an eye or an opening in the capsular bag of an eye comprising:
- a substantially circular lens having a substantially U-shaped annular channel extending inwardly along the perimeter thereof, said channel being adapted to receive therein the periphery of the iris of an eye or an opening in the capsular bag of an eye and wherein said circular lens is a thin membrane having a plurality of concentric circular grooves formed therein, said concentric circular grooves forming a plurality of concentric annular prisms.
An intraocular lens adapted to receive the periphery of the iris of an eye or an opening in the capsular bag of an eye comprising:
- a flexible annular ring having an outer upper flange, an outer lower flange, and an inner wall interconnecting said flanges, said flanges being spaced to receive therebetween the periphery of the iris or an opening in the capsular bag of an eye;
- a reinforcement ring attached to said annular ring, said reinforcement ring being manufactured from a material having a higher stiffness than the material from which said annular ring is manufactured;
- and
- a substantially circular lens operatively interconnected to said inner wall.
An intraocular lens adapted to receive the periphery of the iris of an eye or an opening in the capsular bag of an eye comprising:
- an annular ring having an outer upper flange, an outer lower flange, and an inner wall interconnecting said flanges, said flanges being spaced to receive therebetween the periphery of the iris or an opening in the capsular bag of an eye;
- a lens operatively interconnected to said inner wall;
- and
- a fixation member extending radially outwardly from said inner wall.
