Abstract
An intraocular lens, with equal conic surfaces, is intended to replace the crystalline lens in the posterior chamber of a patient's eye, in particular after a cataract extraction. The lens provides optical power to focus objects onto a patient's retina. In addition the lens surfaces are shaped to reduce optical aberrations at the retina and are tolerant to lens tilt and decentration within the eye. The lens is designed to have zero longitudinal ray aberrations at a specific ray height.
