Abstract
An improved multifocal design for an ocular implant is provided. This ocular implant includes an intraocular lens (IOL) and a number of haptics. The IOL passes optical energy. A microstructure within the IOL places the IOL under tension. The microstructure is operable to be broken in a controlled manner to release tension in the IOL and reshape the IOL. This may be done at any time post operatively and in conjunction with wavefront aberrometry to provide improved results. The haptics mechanically couple to the IOL in order to position and secure the IOL within the eye.
