Visual outcomes after implantation of a presbyopia-correcting IOL that combines extended depth-of-focus and progressive phase complementarity optics.

PURPOSE: To evaluate clinical outcomes after implantation of new presbyopia-correcting intraocular lens (IOL): Artis Symbiose® (Cristalens Industrie, France).

SETTING

Tertiary referral center, Brest, France.

DESIGN

Non-comparative prospective interventional study.

METHODS

Patients undergoing bilateral IOL implantation were included. Visual acuity (VA) for distance, intermediate (70cm) and near (40cm) vision were measured. In addition, defocus curves were obtained at 1 and 6months, and a reading speed test was assessed using the Salzburg Reading Desk® (SRD) 3months after surgery. The VF-14 questionnaire was evaluated at 1, 3 and 6months after surgery to measure spectacle independence, and a level of satisfaction questionnaire was completed at the 6-month follow-up visit.

RESULTS

The study included 48 eyes. Mean postoperative monocular uncorrected VA, for MID and PLUS respectively, was 0.028±0.08 LogMAR and 0.057±0.10 at distance (UDVA), 0.035±0.10 and 0.037±0.09 at intermediate (UIVA), 0.078±0.11 and 0.030±0.10 at near (UNVA). Binocularly, uncorrected VA was -0.022±0.02 at distance, -0.002 at intermediate, and 0.015 at near. The binocular defocus curve at 6months after surgery was above 0 LogMAR between +0.50 D and -2.50 D. The mean satisfaction rate at 6months was 83%.

CONCLUSION

The Artis Symbiose® IOL provides functional uncorrected visual acuity at distance, intermediate and near positions, without the need for additional optical aid. It is an effective option in active presbyopic patients, with a continuous and extended depth-of-focus, providing added value compared to trifocal implants.
