Abstract Details


To report on the clinical outcomes with the Tecnis Symfony extended range of vision intraocular lenses in a clinical setting.


Optegra Eye Hospitals, UK


Observational case series comprising data of 983 implantations of the Tecnis Symfony (AMO) following cataract or refractive lensectomy surgery. The mean ± SD age of the patients was 63±8 years (range 40 to 86 years). Operative and post-operative complications were analysed. Monocular uncorrected distance visual acuity (UDVA) and monocular near visual acuity (NVA) was recorded along with subjective refraction data. Data on patient-reported outcomes including spectacle independence and dysphotopsia were also captured. Additionally, in a sub-group of 113 eyes undergoing femtosecond assisted surgery outcomes data were analysed for comparison.


No operative or post-operative complications were recorded in 99.7% and 94.7% of eyes respectively. Post-operatively, 97% of eyes achieved 20/40 or better UDVA and 66% achieved 20/20 or better UDVA. Post-operative spherical equivalent refraction was within ±1.0D in 97% of cases and within ±0.50D in 83% of cases. In 89% of cases NVA was N6 or better. 80% of the patients reported freedom from the need to wear spectacles and 34% of patients reported being free from troublesome glare or haloes. 100% of patients reported they would be willing to recommend the procedure to family and friends.


Early observations with this extended range of vision lens demonstrated low complication rates, good levels of vision at multiple distances and high levels of patient satisfaction.
