Purpose

The aim of this randomized comparative study was to compare the performance of two advanced monofocal IOLs, the RayOne EMV and Alcon Acrysof IQ Vivity. Target refraction was set for mini-monovision, where the dominant eye was set for emmetropia (0 diopters [D]) and the non-dominant eye for slight myopia (-0.5 D).

Setting

Vienna Institute for Research in Ocular Surgery, a Karl-Landsteiner-Institute, Vienna, Hanusch Hospital, Vienna

Methods

This study was conducted in a randomized, prospective, single-center design. Randomization was performed by using an online randomization tool that indicated which patient received which IOL. Preoperatively, a slitlamp examination, keratometry and biometry, as well as refraction was performed. The follow-up visits were scheduled two weeks and three months after surgery including refraction and visual acuity testing for far (4 m), intermediate (60cm) and near distance (40cm). Furthermore, a defocus curve, tests for reading, halo and glare.

Results

At the time of abstract submission, the study recruitment of patients was already finalized. Preliminary data of 10 patients of each group (in a total of 48 patients) showed a significant improvement in uncorrected distance visual acuity for the RayOne from 0.3 ± 0.2 logMAR to -0.02 ± 0.1 logMAR (p < 0.001) and Alcon Acrysof from 0.45 ± 0.21 logMAR to 0.04 ± 0.12 logMAR (p< 0.001) with no significant difference between the groups. Uncorrected intermediate visual acuity showed no significant difference between the groups with 0.16 ± 0.09 logMAR and 0.15 ± 0.08 logMAR(p = 0.68). The uncorrected near visual acuity showed a significant difference with 0.37 ± 0.14 logMar for RayOne EMV and 0.26 ± 0.13 for Alcon Acrysof IQ Vivity (p= 0.0.18).

Conclusions

Preliminary data showed good visual performance for far, intermediate and near distances in both groups. The final data, additionally including the optical disturbance profile and reading speed, will be presented at the ESCRS 2023.
