Eduardo F Marques,1 António Castanheira-Dinis2 1Department of Ophthalmology, Hospital da Cruz Vermelha, Lisboa, Portugal; 2Visual Sciences Research Centre, Universidade de Lisboa, Portugal 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 Portable Vaporizers (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 Wooden Dollhouse 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.Keywords: accommodating IOL, cataract surgery, intraocular lens, presbyopia.
