Visual Outcomes In Patients Implanted With Hybrid Multifocal And Extended Depth Of Focus Intraocular Lenses Using Progressive Addition Diffractive Technology.

To evaluate the effectiveness of vision restoration, visual quality, and patient satisfaction with hybrid multifocal and Extended Depth of Focus (EDOF) intraocular lens (IOL) implants featuring progressive addition diffractive technology. The investigation focuses on the Artis Symbiose MID and PLUS lenses (Cristalens Industrie, Lannion, France) in presbyopic patients who underwent cataract surgery between 2023 and 2024.

30 eyes from 19 cataract patients with presbyopia underwent mono- or binocular implantation of the investigational multifocal lenses. In cases of binocular implantation, one eye always received the MID lens, while the fellow eye was implanted with the PLUS model. The average age at surgery was 65.3 ± 11.5 years. Refractive outcomes were recorded for each case. Corrected vision at various distances (far, intermediate, near) was measured mono- and binocularly using the Snellen chart, with results later converted to logMAR. Visual continuity across distances and binocular complementarity were assessed using distance-corrected visual acuity defocus curves. Halos and overall satisfaction were evaluated via a self-designed questionnaire.

Results were obtained after a follow-up period of 3 to 12 months, depending on patient availability. Postoperative spherical equivalent refraction error was within 1.00 diopter (D) of the target emmetropia in all cases (100%). For the MID and PLUS models, 81% and 85% of eyes, respectively, were within 0.50 D. Visual acuity defocus curves demonstrated consistently good vision quality across the examined range, with the two IOL models complementing each other when implanted binocularly. Binocular defocus range reached 3.25 D above 0.10 logMAR and 3.50 D above 0.20 logMAR. Patients reported high satisfaction and a very low incidence of halos.

The Artis Symbiose complementary IOL system delivered clear and comfortable vision across all distances. It presents a promising solution for restoring vision at multiple ranges in diverse patient groups, providing excellent visual quality and a high satisfaction rate.
