Zeiss supply the Acri.LISA multifocal lens. This defractive lens has two interesting advantages. Firstly it can be inserted through a smaller incision (approximately 1.6mm) than either the ReSTOR® or Technis lens, and available in a toric version with a wide range of spherical power. Like the others it is also has an aspheric design. The latest version is the Acri.LISA toric 466TD (Acri.TEC Germany). Clinical experience with this lens is limited. It does have …
