Energy efficiency of a new trifocal intraocular lens
(2014-01-15)
Article
Open AccessThe light distribution among the far, intermediate and near foci of a new trifocal intraocular lens (IOL) is experimentally determined, as a function of the pupil size, from image analysis. The concept of focus energy ... -
