INTRAOCULAR LENS WITH SHAPE CHANGING CAPABILITY TO PROVIDE ENHANCED ACCOMODATION AND VISUAL ACUITY

摘要

An intraocular lens for providing a range of accommodative vision, an extended depth of focus, or enhanced performance through the asymmetric transfer of ocular forces to the lens. The intraocular lens contains an optic and a haptic. The shape and/or material of the haptic results in the transmission of ocular forces to particular regions in the optic. Greater forces applied to particular regions result in deformation of that region and increased power.

主权项

1. An intraocular lens, comprising:
an optic adapted to focus light on the retina when disposed in the eye, the optic having a first zone having a distance vision power and a second zone being adjustable through a range of powers greater than the distance vision power, the first zone being intersected by the central optical axis, the second zone being off-set from the first zone; and a haptic, comprising:
an outer annular member;an inner annular member disposed inside at least the second zone of the optic; anda plurality of arms extending between the inner and outer annular members; wherein the intraocular lens is adapted to respond to ocular forces to adjust the power of the second zone.
