Abstract Details

Purpose:

To visualize the optical pathway of different multifocal intraocular lenses (MIOLs).

Setting:

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

Methods:

We analyzed different multifocal intraocular lenses with different optical designs. The IOLs were placed in an eye model on an optical bench including an artificial cornea. Monochromatic green laser light was projected through the lens in the eye model. Images of the optical pathway, that could be made visible by means of a fluorescein solution, were taken with a digital camera.

Results:

Bifocal diffractive and segment IOL models showed two defined foci for near and distance vision. Trifocal IOLs showed three distinct foci. Extended Depth of Focus IOLs showed an elongated focus.

Conclusions:

The optical bench analysis can assess the different foci in all types of MIOLs regardless to their optical principle. The diffractive MIOLs show a circular pattern of light distribution. The segment MIOL show a light distribution with a distinct higher brightness presumably due to a lower loss of contrast than the other MIOLs.
