Abstract Details

Purpose:

To study differences in postoperative straylight for different multifocal intraocular lenses (IOLs) after uneventful crystalline lens exchange.

Setting:

Systematic literature review with retrospective data analysis. Rotterdam Ophthalmic Institute, Rotterdam, the Netherlands.

Methods:

A comprehensive review with retrospective analysis of prospectively-collected cross-center data was carried out to assess straylight in normal pseudophakic eyes. Studies reporting straylight values obtained with the natural pupil using the C-Quant device (Oculus Optikgeräte GmbH, Germany) after uneventful phacoemulsification and following multifocal IOL implantation were used for this analysis. Based on the material characteristic, the identified multifocal IOL models were partitioned into a hydrophilic and a hydrophobic group. The age-adjustment was performed using a straylight age-dependency norm for pseudophakic eyes. This norm also served as a reference to compare different IOLs.

Results:

The literature review revealed 8 studies (754 eyes), most of them reporting on more than one multifocal IOL model. The IOL models used in these studies were SeeLens (Hanita Lenses, Israel), AT Lisa809M/MP (Carl Zeiss Meditec, Germany), Mplus (OculentisGmbH, Germany), SA60D3/SN60D3 (Alcon Laboratories, Inc.), ReZoom (Abbott Medical Optics, Inc.), SN6AD1 (Alcon Laboratories, Inc.) and ZM900 (Abbott Medical Optics, Inc.). Compared to the normative value, they had an average difference in straylight of -0.09 log units, -0.04 log units, -0.03 log units, 0.00 log units, 0.01 log units, 0.02 log units and 0.05 log units, respectively. The difference between hydrophilic and hydrophobic multifocal IOLs was -0.06 log units (p=0.002, Mann-Whitney test) in favor of the hydrophilic ones.

Conclusions:

The hydrophilic material presents less straylight by comparison to the hydrophobic group, which might result in decreasing the risk of optical side effects like disability glare and halos after multifocal IOL implantation, and consequently, improving patient satisfaction. How this difference can be understood, and whether other IOL factors play a role, must be studied.
