Abstract: The present disclosure provides an ophthalmic lens that is disposed to balance coma aberrations if the lens, when inserted in a patient's eye, is decentered or tilted with respect to an optical axis of the patient's eye, and maintain a substantially diffraction-limited image quality if the lens, when inserted in the patient's eye, is centered with respect to the optical axis of the patient's eye. The lens may include an optic having an anterior surface and an opposing posterior surface disposed about an optical axis of the lens. One of the surfaces (e.g., the anterior surface) may have a semi-aspheric surface profile, which includes an inner region having a substantially spherical surface profile and extending radially from the optical axis of the lens to a first boundary, and an outer region having an aspherical surface profile and extending radially at least beyond the first boundary to a second boundary.
