Flexivue Microlens
Encyclopedia
The Flexivue Microlens, a corneal inlay treatment for presbyopia
, is 3-mm in diameter and about 15 microns thick. The lens is placed about 280-300 microns deep in the cornea of the patient's non-dominant eye through a pocket created using a femtosecond laser. The specific vision-correcting prescription for each patient is incorporated in the outer area of the lens. The procedure lasts about 10 minutes, and after the lens insertion, the pocket self-seals and holds the lens in place. The Flexivue Microlens procedure is easily reversible by opening the corneal pocket, removing the lens, and replacing it immediately.

of patients that have received the Flexivue Microlens, show that it improves near vision in patients with emmetropic presbyopia
without compromising binocular distance visual acuity
. Patients achieved rapid improvement in near vision with no change in binocular distance uncorrected visual acuity. One hundred percent of patients gave ratings of excellent or good to questions about perceptions of their uncorrected near vision, distance vision in the operated eye, and binocular uncorrected distance vision. With a single exception, no patient used glasses for reading, and the remaining patient reported wearing glasses for near visual activities less than 50 percent of the time.
Presbyopia
Presbyopia is a condition where the eye exhibits a progressively diminished ability to focus on near objects with age. Presbyopia’s exact mechanisms are not known with certainty; the research evidence most strongly supports a loss of elasticity of the crystalline lens, although changes in the...

Visual acuity
Visual acuity is acuteness or clearness of vision, which is dependent on the sharpness of the retinal focus within the eye and the sensitivity of the interpretative faculty of the brain....
