Abstract Details

Purpose:

To compare different trifocal intraocular lenses (IOLs) at the optical bench regarding their optical quality.

Setting:

David J Apple International Laboratory for Ocular Pathology, University Eye Hospital Heidelberg, Heidelberg, Germany

Methods:

We analyzed the FineVision (PhysIOL, Belgium), the AT LISA tri 839MP (Zeiss, Germany) and the AcrySofIQ PanOptix (Alcon, USA) with a power of 21D for the distance using the OptiSpheric optical bench (Trioptics, Germany). The addition for the near and intermediate distances are as follows: +3.5D/+1.75D (FineVision), +3.33D/+1.66D (AT LISA) and +3.2D/+2.2D (PanOptix). We evaluated the modulation transfer function (MTF) at a spatial frequency of 50 lp/mm and the Strehl ratio using a 3 mm and 4.5 mm aperture.

Results:

The MTF at 50lp/mm (FineVision/AT Lisa/PanOptix) at the far focus was 0.385/0.397/0.401 (3mm aperture) and 0.488/0.285/0.435 (4.5mm aperture). At the intermediate focus, the MTF was 0.160/0.155/0.155 (3mm aperture) and 0.093/0.114/0.140 (4.5mm aperture). The MTF at the near focus was 0.218/0.184/0.402 (3mm aperture) and 0.187/0.185/0.177 (4.5mm aperture). The Strehl ratio was 0.347/0.294/0.368 (3mm aperture) and 0.212/0.146/0.297 (4.5mm aperture) at the far focus. At intermediate distances, the Strehl ratio was 0.177/0.188/0.176 (3mm aperture) and 0.088/0.092/0.126 (4.5mm aperture). The Strehl ratio was 0.296/0.281/0.456 (3mm aperture) and 0.151/0.164/0.183 (4.5mm aperture) at the near focus.

Conclusions:

Evaluation of the three trifocal IOL models at the optical bench could show distinct peaks at the far, intermediate and near focus as well as comparable results regarding their performance.
