Sondra Black Crystal Clear Vision Canada, ON, Canada Purpose: To combine the increased depth of focus of the TECNIS® Symfony intraocular lens (IOL) with a TECNIS Multifocal (MF) low-add IOL (+3.25) to enable a patient to be less dependent on corrective lenses.Setting: Clinic in Canada.
Design: Single-center, prospective, open-label.Materials and methods: Fifty patients were enrolled Food for bilateral surgery.Patients were implanted with TECNIS Symfony Extended Range of Focus lens in the dominant eye, and TECNIS low-add +3.
25 MF IOL in the non-dominant eye.Patients were ≥18 years of age and had best-corrected visual acuity >20/30 in both eyes, pupil size >3.5 mm, and <1.
5 D of corneal astigmatism.Patients were evaluated preoperatively, operatively, and postoperatively on Day 1, Day 7, Month 1, and Month 3.Postoperative evaluations at Month 3 were completed by 32 of 50 patients enrolled, and included distance, intermediate and near visual acuity (VA), and subjective outcomes.
Results: Three months postoperatively, binocular results without correction revealed 97% (29/30) of patients had distance VA of 20/20 or better, 97% (29/30) had intermediate VA of 20/25 or better, and 94% (28/30) had near VA of 20/25 or better.At Month 3, the majority of patients reported “none” for visual symptoms of glare (30/30, 100%), halo (29/30, 96.6%), starbursts (29/30), or other – blur (30/30, 100%).
Conclusion: Three months postoperatively, the combination of the increased depth of focus of the TECNIS Symfony IOL with a TECNIS MF low-add (+3.25) IOL may provide excellent uncorrected VA at near, intermediate, and far distances with minimal Accessories ocular symptoms.Keywords: extended range of vision, TECNIS Symfony, multifocal IOL, low-add IOL, ZXR00, ZLB00, contralateral, blended vision .
