Abstract Details

Purpose:

To visualize the optical pathway and assess the optical quality of extended depth of focus (EDOF) and trifocal intraocular lenses (IOLs).

Setting:

The David J. Apple International Laboratory for Ocular Pathology, Department of Ophthalmology, University of Heidelberg

Methods:

Seven different IOLs were studied: 4 EDOF (Tecnis Symfony[Abbott], MiniWell Ready[Sifi], IC-8 [AcuFocus], Comfort MF-15[Oculentis] and 3 trifocal (AT LISA Tri 839MP[Carl Zeiss Meditec], AcrySof IQ Panoptix[Alcon], FineVision MicroF[PhysIOL] IOLs. Each IOL was placed in model eye on optical bench. Monochromatic green laser was projected through the lens. Images of the optical pathway, made visible by fluorescein solution, were taken with digital camera. The optical quality was analyzed using the optical bench OptiSpheric Pro II(Trioptics, Germany). The modulation transfer function (MTF) and Strehl Ratio (SR) were measured for apertures of 3.0mm and 4.5mm.

Results:

The EDOF IOLs showed characteristic ranges of focus innate to their design, while the trifocal IOLs showed asymmetric optical pathway and energy distribution. Both EDOF and trifocal IOLs exhibited good results for the far focus and functional results for the near focus.

Conclusions:

Optical pathway imaging can help assess the different foci and the energy distribution of MIOLs for a better understanding of the optical principle. The optical quality can be analyzed by measuring the MTF and SR.
