| Zusammenfassung: | BackgroundKnowledge of the optical quality of different trifocal intraocular lenses (IOL) is important in customized patient care.ObjectiveDifferent trifocal IOL were compared regarding their optical quality.Materials and methodsWe analyzed the FineVision (PhysIOL, Liège, Belgium), the AT LISA tri 839MP (Zeiss, Oberkochen, Germany), and the AcrySofIQ PanOptix (Alcon, Fort Worth, TX, USA) with a power of +21D for the distance using the OptiSpheric IOL PRO optical bench (Trioptics, Wedel, Germany). The additions for the near and intermediate distances were as follows: +3.5D/+1.75D (FineVision), +3.33D/+1.66D (AT LISA tri), and + 3,25D/+ 2,17D (PanOptix). We evaluated the modulation transfer function (MTF) at a spatial frequency of 50lp/mm and the Strehl ratio using 3‑ (photopic) and 4.5-mm (mesopic) apertures.ResultsThe MTF at 50 lp/mm (FineVision/AT Lisa tri/PanOptix) at the far focus was 0.373/0.399/0.400 (3-mm aperture) and 0.512/0.311/0.243 (4.5-mm aperture). At the intermediate focus, the MTF was 0.162/0.147/0.153 (3-mm aperture) and 0.092/0.125/0.137 (4.5-mm aperture). The MTF at the near focus was 0.229/0.192/0.404 (3-mm aperture) and 0.217/0.212/0.169 (4.5-mm aperture). The Strehl ratio was 0.335/0.298/0.370 (3-mm aperture) and 0.243/0.180/0.270 (4.5-mm aperture) at the far focus. At intermediate distances, the Strehl ratio was 0.189/0.185/0.162 (3-mm aperture) and 0.099/0.097/0.114 (4.5-mm aperture). The Strehl ratio was 0.305/0.283/0.464 (3-mm aperture) and 0.177/0.181/0.155 (4.5-mm aperture) at the near focus.ConclusionEvaluation of the three trifocal IOL models at the optical bench could show distinct peaks at the far, intermediate, and near focus. The results were comparable in terms of optical performance. |
