Purpose
To describe and compare the visual acuities and spectacle independence of patients implanted binocularly with three extended depth of focus IOLs, one of them based on a wavefront shaping technology (AcrySof IQ Vivity®), two of them with a technology based on diffraction (AT LARA 829MO® and TECNIS® Symfony ZXR00), and a monofocal lens (Acrysof IQ® SN60WF) used as control.
Setting
Vallès Ophthalmolgoy Research. Barcelona.
Methods
Prospective Randomized Controlled Trial with 22 patients included per group. Patients were implanted bilaterally with the same IOL model. Visual Acuities were performed using ETDRS charts at far distance (4m), intermediate (66cm) and near (40cm). Patient satisfaction was assessed using IOL-SAT questionnaire. Outcomes were evaluated at the 3 month follow up visit.
Results
Binocular UDVA and CDVA at far distance showed no statistical differences between the groups (p= 0,187 and p=0,129 respectively). The DCIVA showed differences between AcrySof IQ Vivity - Symfony ZXR00 (p=0,048), AcrySof IQ Vivity -Monofocal (p<0,001), AT LARA 829MO -Mono (p=0,001), with better DCIVA achieved by AcrySof IQ Vivity (0,10 ± 0,09). At near distance, best results were obtained with AcrySof IQ Vivity (0,22 ± 0,11) compared to AT LARA 829MO (0,28 ± 0,13), Symfony ZXR00 (0,37 ± 0,07) and the monofocal lens (0,47 ± 0,10). Concerning the spectacle independence, better results were obtained with AcrySof IQ Vivity lens, where 54,5% never used glasses compared to AT LARA 829MO (40%), Symfony ZXR00 (33,3%) and monofocal (14,3%)
Conclusions
The results showed that extended depth of focus lenses achieved similar visual acuity at far distance compared to the monofocal group. Relevant clinical and statistical differences were found at intermediate and near distances, with better results obtained from the lens based on a wavefront shaping technology compared to the diffractive designs. As expected, worse results were achieved by the monofocal lens at intermediate and near distances. The spectacle independence results were in agreement with the visual acuities achieved with each lens.
