A dynamic accommodative intraocular lens is provided in which a central lens portion of the intraocular lens undergoes dynamic change in curvature to adjust focus from distant objects to those nearby in response to natural accommodative actions of the patients eye. The intraocular lens utilizes fluid movement from flexible fluid reservoirs defined along or adjacent haptic elements of the intraocular lens, which are engaged and compressed by the accommodating movements of the ciliary body of the patients eye to cause expansion and flattening of the intraocular lens to adjust the optic power of the lens.
