A comparative evaluation of three extended depth of focus intraocular lenses

Abstract

Purpose

To compare the refractive and visual performance of three Extended Depth of Focus (EDOF) intraocular lenses (IOLs) after uncomplicated cataract surgery.

Setting

Centre IRIDIS, Albi, France.

Design

Comparative retrospective study.

Methods

Patients with cataracts and without other eye diseases were enrolled for monocular implantation of EDOF IOLs on the dominated eye by the same surgeon between 2018 and 2021, using either the IsoPure (BVI-PhysIOL, Belgium), the Synthesis+ (Cutting Edge, France), or the Lucidis (SAV-IOL, Swiss). Refraction, Uncorrected Distance Visual Acuity (UDVA), Corrected Distance VA (CDVA), Uncorrected Near VA (UNVA), Distance-Corrected Near VA (DCNVA), 25% Contrast CDVA, and Defocus Curve were assessed 3-months postoperatively.

Results

A total of 64 eyes of 64 patients were included in this study (IsoPure n = 22; Synthesis+ n = 20, Lucidis n = 22). CDVA, 25% Contrast CDVA and DCNVA were significantly better for Lucidis than IsoPure or Synthesis+. No significant difference was observed for CDVA and 25% Contrast CDVA between IsoPure and Synthesis+. DCNVA was significantly better for Lucidis and Synthesis+ with respectively 0.08 LogMAR ± 0,09 and 0.29 LogMAR ± 0.13, compared to 0.40 LogMAR ± 0.17 for IsoPure (p < 0.05).

Conclusions

Lucidis showed more efficient distance, low contrast, and near vision than IsoPure and Synthesis+. Synthesis+ seems to be more efficient in intermediate vision than other groups. Each EDOF IOLs provided good distance vision without creating spontaneous complaints of photic phenomena. Refractive EDOF IOLs, especially Lucidis, are efficient for patients wishing to improve their vision without dysphotopsia.
