Abstract Details

Purpose:

To present a methodology to simulate the effect of wavefront aberration profiles of multifocal intraocular lens implants in eyes with elliptical pupils.

Setting:

University of Valencia, Burjassot, Valencia, Spain.

Methods:

A method based on previous reports of Zernike transformation was developed into a MatLab code to recalculate wavefront aberration profiles of known multifocal IOLs over elliptical pupils. The method turns a given set of Zernike coefficients into a transformed set for new pupils determined by its conversion factors such as scaling, translating, rotating or elliptical transformation considerations. This method encapsulates the data so that it is possible to handle any defined functions upon it, such as 3D representation or root-mean-square (RMS) variation, thus gaining control over its properties and over any conceivable transformations.

Results:

An initial set of Zernike coefficients was assumed for a given multifocal IOL profile. Several converted wavefronts were derived from it considering scaling and elliptical transformations at different orientations. The RMS variation for each one of them with respect to the initial set was computed and analysed.

Conclusions:

The presented method could lead to the development of new strategies to assess wavefront and better predict the optical behaviour and visual outcome of multifocal IOL implantation in patients with, either congenital or acquired, elliptical pupils, particularly when considering asymmetric designs.
