Accommodating Intraocular Lens with Haptics for Sulcus Fixation

摘要

An accommodating intraocular lens construction includes a lens of fixed optical power to correct refractive error and a lens of variable power to restore accommodation of the eye, which variable lens can have two optical elements which either shift perpendicular to the optical axis, or which variable lens can have two elements which move along the optical axis, as in a telescope, and which construction has at least one haptic for movement to provide transfer of movement of said driving means to at least one of said optical elements and at least one additional haptic for sulcus fixation to provide limitation of movement of at least one component of the lens along the optical axis with movement of additional haptic which is largely independent from the haptic for movement.

1. An accommodating intraocular lens construction including:
for optical functions, for correction of refractive error of the aphakic eye, at least one lens of fixed optical power to correct, and, for restoration of accommodation of the eye, at least one lens of variable optical power, for mechanical functions, at least one haptic for movement, which haptic is coupled to at least one driving means in the eye and which haptic is adapted to provide transfer of movement of said driving means to at least one of said optical elements,wherein the lens construction comprises, for additional mechanical functions, at least one haptic for sulcus fixation adapted to provide limitation of movement of at least one component of the lens construction along at least one axis.
