Abstract Details

Purpose:

To compare through focus image performance of three trifocal IOL models

Setting:

Vision Science/Optics Laboratory at Alcon Research Ltd, USA

Methods:

Laboratory bench simulation for pseudophakic eyes was performed with a new non-sequential order Presbyopia Correcting trifocal IOL, the Zeiss AT Lisa tri 839 MP, and PhysIOL FineVision Micro F12 IOLs. TF-MTF Curves simulating the viewing distance from infinity to 40cm were generated with IOLs in model eye environment.

Results:

The novel presbyopia correcting IOL, the Zeiss AT Lisa tri 839 MP, and PhysIOL FineVision Micro F12 IOLs were measured. The Zeiss AT Lisa tri 839 MP, and the PhysIOL FineVision Micro F12 IOLs show distance and near MTF with an additional intermediate focus at 80cm. The novel presbyopia correcting IOL provides distance and near MTF with an additional intermediate focus at 60cm.

Conclusions:

The TF-MTF Curves for novel presbyopia correcting IOL and two trifocal IOLs all show a distance and a near focus in the laboratory simulation. The novel presbyopia correcting IOL provides an intermediate focus at 60 cm, which is believed to improve spectacle-independent viewing of devices such as smartphones than the Zeiss AT Lisa tri 839 MP, and the PhysIOL FineVision Micro F12 IOL Models.
