Presbyopia, the normal progressive loss of accommodation, affects all individuals beginning in middle age, regardless of any underlying refractive error. This relentless loss of near vision and dependency on glasses for near work may be particularly distressing for individuals with emmetropic vision who have previously enjoyed excellent uncorrected vision at all distances.
Interest in developing a surgical correction for presbyopia has resulted in several treatment options. Some of these techniques rely on scleral modification, some use implantation of presbyopia-correcting intraocular lenses (IOLs), and others depend on the creation of a multifocal cornea by use of lasers or corneal stromal modifications. More recently, the development of corneal inlays has introduced a new option for patients.
