Abstract

Aspheric intraocular lenses(IOLs)have been shown to provide better quality of vision than spherical IOLs.However,these lenses are not ideal for all patients.Surgeons may have different strategies for compensating for the patients's cornea spherical aberration,targeting a postoperative spherical aberration of zero or +0.10 ?m.But we must know that the negative spherical aberration aspheric IOLs require very good centration with respect to the visual axis of the eye.
