In an attempt to gain more market share, some manufacturers use confusing marketing messages and claim that their IOLs offer advantages over competitors’. In actuality, these claims are often based on minor changes in lens design. The Table summarizes the multifocal IOLs that

The Table summarizes the multifocal IOLs that are commercially available. These IOLs use refractive and diffractive principles, usually in combination, to achieve multifocality.
