Abstract

Purpose

This study presents a detailed optical characterization of three intraocular lenses (IOLs) comparing two so called “enhanced range of field”, Evolux IOL and Tecnis Eyhance IOL and one so called “narrow range of field”, a standard monofocal IOL Acrysof IQ.

Methods

The measurements are performed using the PMTF optical bench, basing on the Modulation Transfer Function (MTF) to evaluate the optical performance of each lens. The MTFa, representing the area under the MTF curve, is utilized as a key and synthetic metric to quantify performance across different spatial frequencies, providing insights into the IOLs’ behavior as defocus varies.

Results

The results highlight the strengths and the weaknesses of the IOLs, with the Evolux showing a broadest depth of focus. The USAF resolution target is used to qualitatively assess the image reproduction at far, intermediate, and near distances, offering a visual representation of the IOLs’ capabilities.
