[Spherical aberration, contrast sensitivity and color discrimination after cataract surgery with the aspherical intraocular lens].


OBJECTIVE To determine whether implantation of an intraocular lens (IOL) with a modified prolate anterior surface results in reduced spherical aberration and improved contrast sensitivity after cataract surgery. METHODS Consecutively 72 eyes were selected from 53 senile cataract patients who had received phacoemulsification and IOL implantation in Peking… (More)
