PARIS — Three-month results of the European study on the Tecnis Symfony extended range of vision IOL show a good performance at all distances, a low incidence of halos and glare, and a high degree of spectacle independence.
The latest product of the Tecnis family (Abbott Medical Optics) was conceived to overcome the limitations of classic diffractive IOLs in terms of depth of focus and quality of vision. The diffractive echelette design of the Symfony produces a pattern of light diffraction that elongates the focus, extending the range of vision, while halos and glare are comparable to a monofocal IOL.

The results of the study were presented at the meeting of the French Society of Ophthalmology by Charlotte Hugny-Larroque, MD, on behalf of Béatrice Cochener, MD, PhD, study investigator.
“Uncorrected visual acuity was 20/20 at both distance and intermediate and 20/32 at near, with a smooth transition between distance and near vision. The defocus curve was a continuum and did not show the classic peaks of conventional diffractive IOLs,” Hugny-Larroque said.
Halo and glare were minimal, with 99% of the patients reporting no halo or night glare at all. Patient satisfaction was high. More than 60% were spectacle-free, and 98% said they would recommend the implant to family and friends.
Hugny-Larroque said that the most effective enhancement of near vision was obtained by micro-monovision, with -0.5 D in one eye. - by Michela Cimberle
