Abstract Details


To evaluate and compare the distance, intermediate and near visual acuity, patient satisfaction and contrast sensivity after bilateral implantation of Extended Range of Vision IOL (AMO Tecnis Symfony ) and a Diffractive Trifocal IOL (Zeiss AT Lisa tri 839 )


Hospital St. John, Vienna, AustriaSigmund Freud Private University Vienna, Medical Faculty


In this randomized, controlled, prospective study, 30 patients (age range, 51 to 80 years) with bilateral senile cataract were enrolled. Healty eyes other than Cataract were selected. Subjects received either AMO Tecnis Symfony or Zeiss AT Lisa tri 839 in both eyes on same day and by same surgeon. Three months after surgery Visual acuity, Contrast sensivity test with Opthec 6500 were performed. A subjective questionnaire assesses the overall patient's satisfaction and the amount of photic phenomena for both IOL types.


Both the Tecnis Symfony and the AT LISA IOLs performed well and similarly to each other regarding uncorrected near, intermediate and distance visual acuity. Tecnis Symfony subjects had better contrast sensivity on photooptic levels but did not reach statistical significance. 96% of the Tecnis Symfony patients and 94% of the AT LISA tri patients would choose the same lens again. One subject had IOL exchange (AT Lisa)


According to our results, both groups achieved an excellent visual acuity both for distance and intermediate, and satisfactory for near.
