Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Purpose: To compare the effect of spherical aberration on optical quality in eyes with two different aspherical intraocular lenses Methods: In this prospective, randomized clinical trial 120 eyes of 60 patients underwent phacoemulsification. In patient's eyes an aberration-free aspherical IOL (Aspira-aA; Human Optics) or an aberration-correcting aspherical IOL (Tecnis ZCB00; Abott Medical Optics) were randomly implanted. Three months after surgery visual acuity, contrast sensitivity, wavefront measurements with iTrace as well as tilt and decentration measurements with Visante anterior segment OCT were performed.
