Abstract Details


To present results of implantations of the leading models of multifocal intraocular lenses with extended focus in comparison with trifocal IOLs. New designs of EDOF intraocular lenses use modulation of spherical and chromatical aberration to produce one extended focus instead of three distinct foci, as it is the case with trifocal IOLs. Such designs have been recently introduced by Johnson&Johnson (Symfony) and by SiFi (Mini Well) which is the only progressive IOL without diffractive rings.

Clinical results were shown after implantation of 40 IOLs of four types: Physiol Fine Vision, Alcon Panoptix and Johnson&Johnson Symfony, SiFi Meditech Mini Well. Visual acuity on near and distance, distance range, near contrast sensitivity (Adult Near Contrast Test, Richmond Products Inc.) and reading speed with IReST test in bright and dim light. Subjective satisfaction was also measured.


Distance and near visual acuity with all IOLs was within the range of 0.7-1.2 uncorrected visual acuity (UCVA) and J1- J3, with difference in reading distance that was appx. 7-10 cm longer with EDOF lenses. Intermediate range with J4 letters was between 35-80 cm. Contrast sensitivity for near ranged between 5-7.5% in bright light and 10-12 % in dim light. Reading speed was between 50-65 sec/chart compared to normative of 45-50 sec/chart and was only in average 5 sec longer in dim light. Subjective satisfaction was high in all models with least halos at night vision with Mini Well IOLs.


Newer types of trifocal and EDOF intraocular lenses provide excellent vision at all distances without major loss of contrast sensitivity and near vision in dim light. Adverse light phenomena were not disturbing and were diminishing with time. Whilst near vision was slightly better with trifocal IOLs, distance vision was comparable but with less halos and glare with night driving for Mini Well IOL. Different features of different IOLs are important for individual choice for particular patients' needs.
