Surgical Correction of Presbyopia
While there are some existing treatments that attempt to apply the technology approved for older cataract patients in order to also treat presbyopia, the Presbia Flexivue Microlens™ solution is one of the few surgical procedures specifically targeted for the treatment of presbyopia. In addition, most current alternative procedures for treating presbyopia are cosmetically unappealing, more invasive, and are not reversible.
About 25 percent of the world's population is presbyopic. Studies suggest that approximately 11 percent of the world's population qualifies as candidates for the Presbia Flexivue Microlens™ procedure, allowing for economic and social factors. This represents a growing population of over hundreds of millions of potential candidates annually. Given its ease of use, low cost of entry, speed of application, and exchangeability, we believe that the patented Presbia Flexivue Microlens™ corneal inlay offers a truly comprehensive solution for the treatment of presbyopia.
The Presbia Flexivue Microlens™
Using a femtosecond laser to create a pocket in the cornea, the Presbia Flexivue Microlens™ is implanted using Presbia’s proprietary insertion tool. This tiny lens is only 3 mm in diameter, approximately 15 microns in edge thickness, and is barely discernible when placed within the corneal stroma. The lens is made of a hydrophilic polymer, similar to the kind that has been used to make intraocular lenses (IOLs) for over 20 years. The Presbia Flexivue Microlens™ is easily removable and reversible. |

Why Corneal inlays
Corneal inlays are less invasive and offer much greater patient satisfaction than other types of current or proposed treatments for presbyopia. Most patients with presbyopia use reading glasses as a treatment but are unsatisfied with this option. Other surgical treatments may eliminate the need for reading glasses, but they have side effects which create monovision—not an optimal solution for many patients.
The Presbia Flexivue Microlens™ is easy to implant and, in most cases, the procedure takes less than 10 minutes. The Presbia Flexivue Microlens™ is removable and replaceable if the patient needs additional power later since visual acuity predictably changes with aging.
