Monofocal IOLs are focused at a particularpoint, and may often require reading glasses in order to optimize near vision without glasses. Multifocal lenses are multivision lenses, which enable eligible candidates to see both near, intermediate, and far
objects without the aid of glasses or contact lenses. Multifocal lenses can also be used to treat presbyopia
, an age-related condition in which patients lose their ability to focus clearly on objects within close range. Choice purely depends upon the patient upon usage or need and cost effectiveness as monofocal lens is cheap.
