Influence of Angle and Higher-Order Aberrations on Visual Quality Employing Two Diffractive Trifocal IOLs.

Prospective, randomized, comparative, and controlled study to estimate the association between angle distance and higher-order aberrations (HOAs) with postoperative visual acuity after presbyopia-correcting IOL implantation. Forty-three eyes from 43 patients were included and randomly assigned in two groups for either AT LISA tri 839MP or Acrysof IQ PanOptix IOL implantation. The OPD-Scan III analyzer was utilized to assess the angle distance and higher-order aberration (HOAs).

Comparison of biometric measurements obtained by the Verion Image-Guided System versus the auto-refracto-keratometer.

Purpose: To compare the biometric measurements obtained from the Verion Image-Guided System to those obtained by auto-refracto-keratometer in normal eyes.

Methods: This is a prospective, observational, comparative study conducted at the Asociación para Evitar la Ceguera en México I.A.
