Semi-flexible posteriorly vaulted acrylic intraocular lens for the treatment of presbyopia

摘要

An intraocular lens having an optic and at least one semi-rigid, haptic connected to the optic, both of which may be acrylic. The intraocular lens can have a fixed longitudinal length, e.g., the same fixed length pre-operatively and post-operatively. The intraocular lens can resist deformation, despite contraction and relaxation of the ciliary muscle and fibrosis within the capsular bag, after implantation into the eye using, for example, by the semi-rigid haptics. The intraocular lens can be sufficiently flexible to be compressed from an original configuration to a compressed configuration for insertion into the eye through a small incision and return to the original configuration after implantation into the eye.
