Abstract Details

Purpose:

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)

Setting:

Hospital St. John, Vienna, Austria Krankenhaus der Barmherzige Brüder Wien Sigmund Freud University Vienna

Methods:

In this randomized, controlled, prospective study, 30 patients (age range, 61 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.

Results:

Both the Tecnis Symfony and the AT LISA IOLs performed well and similarly to each other regarding uncorrected near, intermediate and distance visual acuity. Patient satisfaction was high in all cases and there were no intra-operative complications. In the post operative period no adverse events were observed. Tecnis Symfony subjects had better contrast sensivity levels but did not reach statistical significance.

Conclusions:

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