Multifocal Intraocular Lenses: Types and Models

Abstract

As their name suggests, multifocal intraocular lenses allow vision at different distances because this is exactly what presbyopic patients need. At first sight, these type of lenses may appear to have similar characteristics; however, they respond to different objective and subjective surgeon and patient needs. Daily habits, occupation, pupil size, possible presence of an ocular pathology, age, etc., are details that determine the type of multifocal intraocular lens to choose.

This chapter includes the technical details of the 49 most relevant intraocular multifocal lenses available on the international market. The information has been obtained through the Web pages of each manufacturer, information provided by sales managers and in international conferences such as the American Academy of Ophthalmology (AAO), European Society of Cataract and Refractive Surgeons (ESCRS), and American Society of Cataract and Refractive Surgery (ASCRS). Technical details such as refractive behavior, dimensional characteristics, and refractive constants are described in a way to facilitate quick and easy access to the information required. In any case, the need for the surgeon to obtain their own constants according to their experience is always specified.
