Quantification of IOLs’ characteristics through optical measurements: Indications for a pre-implantation vision assessment at different distances

This study reports the measurement, using the Lambda-X PMTF and Lambda-X instruments, of the optical characteristics of three types of intraocular lenses (IOLs) and the subsequent analysis for evaluation and comparison. The optical characteristics of the lenses are evaluated through the Modulation Transfer Function (MTF) in Through Focus mode and with different pupil sizes. The USAF (United States Air Force) resolution target is also used to qualitatively assess the image reproduction at far, intermediate, and near distances, offering a visual representation of the IOLs’ capabilities. The results show different behavior of the lenses in the visual acuity at different distances. In addition, the data were used in combination with previously reported proposals to connect the MTF with postoperative visual acuity.
