Presbyopia correction and accommodative intraocular lenses

Abstract

With ageing, the ability of the eyes to focus near objects is gradually lost. The progression of this loss generally goes unnoticed until near tasks such as reading become impossible at the age of 45-50 years, called presbyopia. Usually, presbyopia is corrected with reading glasses. When a presbyopic person needs lens surgery, for instance to remove an opacified lens, the opportunity occurs to implant a lens that restores the ability to clearly see at all distances. This article discusses several methods for presbyopia correction, including multifocal and accommodative lenses.
