Psychophysical Vision Simulation of Diffractive Bifocal and Trifocal Intraocular Lenses.

In a meta-analysis of 35 multifocal IOLs it was found that better results were obtained with diffractive than with refractive MIOLs or accommodative IOLs, with a possible trend of fewer haloes in diffractive MIOLs than in refractive MIOLs. 5 Although the premium multifocal IOL market is still small in absolute sales compared with the mainstream monofocal IOL market, it is quickly expanding and corresponding commercial interest has recently increased strongly. 6 New players with innovative multifocal IOL design concepts are likely to enter the market.
