Following cataract extraction, an implant is inserted into the capsular bag of the crystalline lens. Light rays are focused on the retina by the biconvex optical part of the implant. Most implants have monofocal and steady optic so that glasses are mandatory to get a corrected image according to the distance. Multifocal intraocular lenses have two drawbacks: a loss in visual acuity and perception of halos. Recently, we have optimised implants likely to offer a slight antero-posterior move of the optic. The efficiency of it is real, although limited. Those implants do not reduce visual acuity and do not create halos.
