Abstract Details


Extended range of vision intraocular lenses (IOLs) have been developed to provide patients a continuous range of functional vision for far, intermediate and near distances, with reduced risk of undesired halos or glare. The aim of this study is to investigate the visual performance of the new Tecnis Symfony IOL under routine conditions.


The International CONCERTO Study Group


Fifty study sites from Finland, France, Germany, Norway, Sweden, Spain and UK will enroll 400 patients with bilateral Tecnis Symfony IOL implantations. Follow-up examinations will take place 4-8 weeks and 4-6 months after surgery. Uncorrected (UDVA) and best-corrected (CDVA) monocular and binocular visual acuity as well as uncorrected near (UNVA, 40 cm) and intermediate (UIVA, 70 cm) visual acuity will be documented. Further study parameters include subjective refraction, decentration/tilt, photic phenomena, spectacle use (distance, intermediate, near), patient and surgeon satisfaction.


An interim analysis (n=63) revealed a binocular decimal UDVA of 0.95 and CDVA of 1.03. Patients had a binocular UNVA of 0.67 and a binocular UIVA of 0.82. Lens position was stable in all evaluated cases. Reading glasses were occasionally used by 28% of the patients and 17% needed reading glasses in more than 50% of the time. Only 6.4% of the patients needed spectacles occasionally for intermediate vision. Halos were reported by 15%, glare by 17% and starburst by 4.2% of the patients. Surgeons and patients were satisfied with the visual performance.


The concept of an extended range of vision seems to meet the patients' demand for a functional vision across all distances. Photic phenomena occurred at a rather low rate.
