Effect of Spherical Aberration on the Optical Quality after Implantation of Two Different Aspherical Intraocular Lenses.

ABSTRACT:

Purpose

To compare the effect of spherical aberration on optical quality in eyes with two different aspherical intraocular lenses.

Methods

120 eyes of 60 patients underwent phacoemulsification. In patients' eyes, an aberration-free IOL (Aspira-aA; Human Optics) or an aberration-correcting aspherical IOL (Tecnis ZCB00; Abott Medical Optics) was randomly implanted. After surgery, contrast sensitivity and wavefront measurements as well as tilt and decentration measurements were performed.

Results

Contrast sensitivity was significantly higher in eyes with Aspira lens under mesopic conditions with 12 cycles per degree (CPD) and under photopic conditions with 18 CPD (p = 0.02). Wavefront measurements showed a higher total spherical aberration with a minimal pupil siz
