Reading glasses may be a thing of the past with a new eye surgery that's being considered for approval by the U.S. Food and Drug Administration.
People reportedly can regain their vision from reading loss and blurriness with KAMRA vision's corneal inlay procedure, developed by the California-based business AcuFocus.
The 15-minute procedure - already approved by 47 countries across Europe, Asia, the Middle East, the Americas and Canada - has been conducted on nearly 20,000 patients.
"After 10 years of development, and thousands of patients treated globally, it is incredible to finally be able to submit this last module to the FDA for U.S. approval," said Ed Peterson, CEO and president of AcuFocus, in a company release.
How Does It Work?
The procedure is for people suffering from presbyopia, a condition that results in reading loss and blurriness. Presbyopia typically affects people in their early to mid-40s.
The surgery creates a small aperture effect, allowing the eye to see near, far and intermediate objects more clearly while maintaining distance.
The way it works is by using the depth-of-focus principle, commonly used in photography, to control light transmissions and allow only central rays to reach the retina through a fixed 1.6 mm aperture inserted on the eye, according to the company.
First, the procedure uses Lasik technology to fix the eye. Then, the aperture - called the KAMRA inlay - is inserted on top of the eye, like built-in reading lenses.
The inlay is smaller than contact lenses.
Patients who undergo the procedure are expected to regain the same vision they had before developing presbyopia. Again, they're able to read text messages, check their wristwatch, work on the computer, and drive - without glasses.
