Abstract An intraocular lens apparatus having an optical lens portion and a mechanism for confining the lens portion within the eye. A marking is applied to the surface of the optical lens portion for indication of a specific zone of the optical lens portion. The marking may consist of an amount of material which is substantially nonreactive to human tissue. The physician is able to align the marking in relation to the pupil of the eye before fixing the optical lens portion within the eye.
