Clinical Performance Of A New Aspheric Dual-Optic Accommodating Intraocular Lens

Purpose: To describe the clinical performance of a new dual-optic intraocular lens (IOL) with an enhanced optic profile designed to mimic natural accommodation.Patients and methods: Prospective multicenter clinical study with the new dual-optic aspheric accommodating IOL (Synchrony Vu) in 74 patients (148 eyes) undergoing cataract surgery. Refractive target was emmetropia. Examinations at 1 month and 6 months included subjective refractions; visual acuities at near, intermediate, and far; mesopic contrast sensitivity with and without glare; safety data; and subjective survey on dysphotopsia (halos and glare).Results: Clinical data at 6 months showed 89% of the eyes within +/- 1.0 D spherical equivalent refraction. Mean binocular uncorrected and distance-corrected visual acuity was 20/20 at far (0.00 +/- 0.11 logMAR and -0.06 +/- 0.08 logMAR, respectively), 20/20 at intermediate (0.01 +/- 0.13 logMAR and -0.01 +/- 0.10 logMAR, respectively), and 20/25 at near ( 0.10 +/- 0.14 logMAR and 0.14 +/- 0.15 logMAR, respectively). Mesopic contrast sensitivity was within normal limits. Seventy-eight percent of the patients had no spectacles and 70% had no dysphotopsia. One eye had IOL repositioning within 1 month of surgery.Conclusion: The new aspheric Synchrony Vu accommodating IOL provided good visual performance at a range of distances without affecting quality of vision and with minimal safety considerations.
