Abstract Details

Purpose:

To study the early refractive results of patients monocularly implanted in BMICS with new EDOF lens Synthesis Plus (Cutting Edge) and IsoPure (BVI-PhysIO)..

Setting:

Centre Ophtalmologique IRIDIS, Albi, France.

Methods:

This prospective study enrolled 40 patients who were implanted on the non-dominant eye in 2018-2020 by the same surgeon in BMICS with Synthesis Plus lens (Cutting Edge) and IsoPure (BVI-PhysIOL). The Synthesis Plus is hydrophilic, IsoPure is hydrophobic acrylic lens, both with modification of asphericity that induces EDOF. Contralateral eye was implanted with a monofocal lens. The following tests were monocularly performed at 1-month post-surgery: best corrected distance VA with low and high contrast, best distance corrected near VA and monocular defocus curve with best distance refraction. Binocular high and low contrast VAs were also measured.

Results:

For the Synthesis Plus 20 eyes from 20 patients (10 females, 10 males) were analyzed at the 1-month. Uncorrected distance and near VAs were respectively 0,11 ± 0,12 and 0,18 ± 0,17 LogMAR. Mean refraction was -0,51 ± 0,33 D. Monocular best corrected distance VA and near VA with distance correction were respectively 0,01 ± 0,02 and 0,29 ± 0,13 LogMAR. All patients reached binocular corrected distance VA of 0,00 LogMAR. Low contrast distance corrected VA was 0,08 ± 0,06 LogMAR monocularly and 0,01 ± 0,02 binocularly. Monocular defocus curve showed a plateau with 2,35D and 1,71D of defocus at 0,3 and 0,1 LogMAR. For the IsoPure the data will be available.

Conclusions:

These new EDOF provide good visual acuity for distance and a comfortable intermediate visual acuity. Maximum distance visual acuity and low contrast vision can be secured with implantation of a monocular lens on the dominant eye while providing a true extended depth of focus on the non-dominant eye. These new EDOF lenses are a good alternative for presbyopia correction without dysphotopsia.
