Design of an actuator for the demonstrator of an intraocular implant with lateral-shift optics

An implantable mechatronic microsystem is an innovative approach to restore the accommodation ability after cataract surgery or in case of presbyopia. A lateral-shift optics has been shown to be suitable for such an Artificial Accommodation System. Two lenses with conjugated polynomial surfaces are shifted against each other laterally to the optical axis for change of refractive power. Shifting of the lenses has to be performed by an actuator subsystem of the implant.
