title: Coaxially sighted intraocular lens light reflex for centration of the multifocal single piece intraocular lens.
abstract: Centration of multifocal Intraocular lenses (IOL) may be critical to ensure optimal function and prevent untoward side effects. Pharmacologic pupillary dilation and constriction may shift the physiologic location of the pupillary center rendering intraoperative positioning of multifocal IOL challenging. Similarly, the anterior capsular center is difficult to pinpoint and may not correspond to either the visual axis or the pupillary center. The visual axis is the only landmark that can be consistently identified prior, during and after cataract surgery. Centering diffractive multifocal IOL on the visual axis may allow more consistent placement and better outcome measures. In the following, we describe a simple technique to center multifocal single piece acrylic IOLs on the visual axis.
