Spherical aberration and coma with an aspherical and a spherical intraocular lens in normal age-matched eyes

After uneventful implantation, the aspherical IOL yielded better ocular aberration and optical quality results than the spherical IOL. Induced coma was somewhat higher in the Tecnis group; however, the overall results were not affected. Physiologic IOL decentration after correct in-the-bag implantation did not negate the advantages of asphericity.
