Objective and Subjective Outcomes of a Trifocal IOL in Eyes With Different AL

Peking University Third Hospital61 enrolled

Overview

This prospective cohort study enrolled patients with implantation of a trifocal IOL. Only one eye of each patient was enrolled. Eyes were devided into three groups according the axial length (AL), including the short AL group, the control group and the long AL group. Manifest refraction, uncorrected and distance-corrected visual acuity at different distances, contrast sensitivity, aberrations and IOL decentration were measured three months after surgery. Spectacle independence, adverse photic phenomena, overall satisfaction and life quality were assessed with a questionnaire.
