The optical design of multifocal intraocular lenses uses concepts that are sometimes difficult to grasp, especially when it concerns diffractive technology and chromatic aberration control. We published an article (available here) that is based on the optical bench analysis of several models of multifocal diffractive implants to describe their main optical characteristics and report their […]

Presbyopia can be corrected with multifocal corneal laser surgery in selected presbyopic hyperopic patients using customized multifocal aspheric correction. We have reported in the November 16 issue of the Journal of Refractive Surgery the clinical results of combined presbyopic hyperopic LASIK corrections obtained with a uniquely designed multifocal method aimed at reshaping the corneal profile […]
