Purpose: to evaluate the effect of visual axis positioning on the optical performance of the Tecnis MIOL and the Diff-aA MIOL.
In this prospective, randomized comparative study 70 eyes of 35 subjects with senile cataract were implanted with the spherical aberration correcting diffractive, bifocal Tecnis ZLB00 IOL, and 60 eyes of 30 age matched subjects with the spherical aberration neutral, diffractive, bifocal Diffractiva IOL. Observation Procedure was performed 1, 3, 6 months postoperatively. Main Outcome Measures included uncorrected and corrected distance and near visual acuity, manifest refraction, ocular aberrations and visual quality metrics with 2mm and 4mm pupil, and the position of visual axis.
