About this study

The investigators aim to compare the visual performance of the most recently introduced extended depth of focus intraocular lenses ; AcrySofTM IQ VivityTM and TECNIS SynergyTM ( an extended depth of focus IOL ) regarding the range of vision (using defocus curve ) , contrast sensitivity( through the modulation transfer function curves ) and their effect on ocular aberrations as the ivestigators believe that proper study of these aspects could influence the investigators choice and guidance to the cataract patient about the most suitable presbyopia correcting IOL .

Read the detailed description

Presbyopia-correcting IOLs can be divided into 4 broad categories: Enhanced monofocal IOLs , Mutifocal IOLs (including diffractive or refractive designs) , extended depth-of-focus (EDOF) IOLs, and accommodative IOLs .

Standard multifocal lenses ( e.g : FineVision® (Physiol, Liège, Belgium) are diffractive IOLs which split incident light into two or more points of focus, but these lenses are limited by the optical aberrations and the presence of secondary out-of-focus image and photic phenomena .

The new Tecnis® EyhanceIOL (model ICB00, Johnson \& Johnson Vision, Santa Ana, CA, USA) is a refractive modified monofocal lens with better intermediate visual acuity than standard monofocal IOLs and eliminates the dysphotopsia that is common with the standard multifocal IOLs and compensates for the spherical aberration of the cornea due to its high order aspheric profile .

The EDOF IOL, or extended range of vision IOL, incorporates a new technology which createsa single-elongated focal point to enhance the depth-of-focus, contrary to monofocal IOLs (in which light is focused on one single point) or MF IOLs (having 2 or 3 discrete points). This elongated focus is introduced to eliminate the overlapping of near and far images caused by traditional MF IOLs, thus eliminating the halo effect .However , EDOF IOLs are thought to be inferior to standard trifocal IOls regarding near vision.

AcrySof™ IQ Vivity™ Extended Vision Intraocular Lens (Alcon, Fort Worth, Texas,USA ) was approved by the Food and Drug Administration in February 2020 and it is considered the most recently introduced non-diffractive EDOF IOL . TECNIS Synergy™ Intraocular Lens (Model ZFR00V) (Johnson \& Johnson Vision,SantaAna, CA, USA) is a continuous depth of focus intraocular lens and was approved by food and drug administration in April 2021 . it combines both elements of standard multifocal and extended depth of focus with preservation of high contrast sensitivity .

The investigators aim to compare the visual performance of the most recently introduced extended depth of focus intraocular lengths ; AcrySof™ IQ Vivity™ and TECNIS Synergy™ ( an extended depth of focus IOL ) regarding the range of vision (using defocus curve ) , contrast sensitivity( through the modulation transfer function curves ) and their effect on ocular aberrations as the investigators believe that proper study of these aspects could influence the ophthalmologists' choice and guidance to the cataract patient about the most suitable presbyopia correcting IOL .

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Range of vision of the different IOLs represented by the defocus curve

    monocular defocus curve will be obtained by using the best corrected distance refraction and measuring the visual acuity Between +1.50 D and- 2.50 D in 0.5-D defocus steps, except in the region from +0.50 D through* 0.50 D, which would be done in -0.25D steps. Letters will be randomly presented to avoid memorization.

    Measured: within 1 month after surgery

Secondary outcomes (1)
  1. Contrast sensitivity (which will be objectively assessed through modulation transfer function ) - Photic phenomena (which will be objectively expressed through the ocular aberration ).

    Modulation transfer function under mesopic eye condition and total ocular aberrations will be assessed using ITrace aberrometer

    Measured: within 1 month after the surgery
