Presbyops Find Eye Correction with Hyperopic OK

By middle age, most people have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. An emerging technique called hyperopic orthokeratology (OK) may provide a new alternative for restoring near vision without the need for glasses, according to "Refractive Changes from Hyperopic Orthokeratology Monovision in Presbyopes", appearing in the April issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The study included 16 middle-aged patients (43 to 59 years) with presbyopia. In all patients, the monocular OK technique reportedly restored near vision in the treated eye.
