Abstract
A supplemental intraocular lenses may be attached to conventional primary intraocular lenses using annular wrap-around clamps or adhesive or laser welding. New primary intraocular lens configurations have pockets for accommodating relatively small, supplemental intraocular lenses therein.
Claims19
A soft supplemental intraocular lens for attachment to a primary intraocular lens having an anterior primary intraocular-lens face, the soft supplemental intraocular lens comprising:
- an optic portion having at least one optical power and an optic-portion periphery, the optic portion being adapted to contact the anterior primary intraocular-lens face of the primary intraocular lens;
- and
- a stretchable peripheral zone surrounding at least 20% of the optic-portion periphery, the peripheral zone having substantially no optical power, having a reduced thickness relative to a thickness of the optic-portion periphery, and being adapted to contact the anterior primary intraocular-lens face, the soft supplemental intraocular lens being deformable for passage through a small incision into an eye.
A soft supplemental intraocular lens for attachment to a primary intraocular lens, comprising:
- an optic portion having at least one optical power and adapted to contact an anterior primary intraocular-lens face of the primary intraocular lens;
- and
- a peripheral zone surrounding at least 20% of the optic portion, the peripheral zone having substantially no optical power, and being adapted to contact a posterior primary intraocular-lens face of the primary intraocular lens located substantially opposite the anterior primary intraocular-lens face, the soft supplemental intraocular lens being deformable for passage through a small incision into an eve.
A soft supplemental intraocular lens for attachment to a primary intraocular lens having an anterior primary intraocular-lens face, the supplemental lens comprising:
- an optic portion having at least one optical power and an optic-portion periphery, the optic portion being adapted to contact the anterior primary intraocular-lens face of the primary intraocular lens;
- and
- a stretchable peripheral zone surrounding substantially all of the optic-portion periphery, the peripheral zone having substantially no optical power and a reduced thickness relative to a thickness of the optic-portion periphery, the soft supplemental intraocular lens being deformable for passage through a small incision into an eye.
A multi-component intraocular lens, comprising:
- a primary intraocular lens having an anterior primary intraocular-lens face;
- and
- a soft supplemental intraocular lens having an optic portion and a peripheral zone, the peripheral zone has substantially no optical power and a reduced thickness relative to a thickness of the optic portion, the peripheral zone surrounding at least 20% of the optic portion and being adhesively secured to the anterior primary intraocular lens face, the soft supplemental intraocular lens being deformable for passage through a small incision into an eye.
A soft supplemental intraocular lens for attachment to a haptic-type primary intraocular lens, the haptic-type primary intraocular lens being adapted to be secured within an eye using at least one haptic member and having an anterior primary intraocular-lens face, the supplemental intraocular lens comprising:
- an optic portion having at least one optical power and an optic-portion periphery, the optic portion being adapted to contact the anterior primary intraocular-lens face, the optic portion periphery having a thickness;
- and
- a peripheral zone surrounding at least 20% of the optic-portion periphery, the peripheral zone having substantially no optical power, having a reduced thickness relative to the thickness of the optic-portion periphery, and being adapted to contact the anterior primary intraocular-lens face, the soft supplemental intraocular lens being deformable for passage through a small incision into an eye.
A soft supplemental intraocular lens for attachment to a primary intraocular lens, the primary intraocular lens having an anterior primary intraocular lens face, a posterior primary intraocular lens face, and a primary intraocular lens curvilinear periphery, the supplemental intraocular lens comprising:
- an optic portion having at least one optical power and a periphery, the optic portion being adapted to contact the anterior primary intraocular lens face;
- and
- a peripheral zone surrounding substantially all of the optic portion, the peripheral zone having substantially no optical power, and an approximately uniform thickness that is less than a thickness of the optic portion periphery, the peripheral zone having a curvilinear periphery, the soft supplemental intraocular lens being deformable for passage through a small incision into an eye.
