Presbia Flexivue Microlens
The Presbia Flexivue Microlens, a corneal inlay treatment for presbyopia, is 3 mm in diameter and about 15 µm thick. The lens is placed about 280-300 µm deep in the cornea of the patient's non-dominant eye through a pocket created using a femtosecond laser.〔("Intracorneal Inlays Showing Positive Outcomes" )〕 The specific vision-correcting prescription for each patient is incorporated in the outer area of the lens.〔("Can't Read the Fine Print? New Vision Options for Baby Boomers" )〕 The procedure lasts about 10 minutes, and after the lens insertion, the pocket self-seals and holds the lens in place. The Presbia Flexivue Microlens procedure is easily reversible by opening the corneal pocket, removing the lens, and replacing it immediately.〔("Intracorneal micro-lens a minimally invasive option for presbyopia" )〕 The Presbia Flexivue Microlens is manufactured by Presbia. 〔("Presbia website" )〕
Results from a one-year follow-up by Prof. Ioannis Pallikaris of patients that have received the Presbia 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.〔("Implant improves near vision" )〕
