New Cornea Inlay Restores Normal Reading Vision

New surgical procedure restores eyesight in those suffering from presbyopia…

New surgery technique, which involves implanting a ring shaped disc into the eye, can dramatically increase the vision of those suffering from presbyopia, or near-sightedness, without affecting distance vision.

Unlike the GlassesOff app (featured in our last post) – the surgery free iPhone app that claims to correct near-sightedness – which has only been tested on some 100 subjects, the Kamra cornea inlay improved near vision in all the 2,000 volunteers who have tested the implant, according to Minoru Tomita, MD, PhD, executive director of the Shinagawa LASIK Center in Tokyo.

In the latest study – involving 450 people in their 40’s, 50’s, and 60’s who could only read large font headlines – 90 percent of participants said they were happy with the results and 95 percent reported being less dependent on reading glasses.

Those in their 40’s were able to read an additional 4 lines 13-15 line optical charts; those in their 50’s could read 5 more; and those in their 60s could read 7 more.

The technique works by taking advantage of the ‘pinhole effect, which block peripheral rays only allowing focused light to reach the retina. To perform the surgery, the same laser used in LASIK laser eye surgery is used to create a flap in the non-dominant eye. The inlay, which weights less than a grain of salt, is placed on the cornea over the pupil and the flap is reattached.

LASIK laser eye surgery can also correct near-sightedness, but this often comes at the expense of slightly reduced distance vision. The new technique however does not compromise the eyesight and can even be performed in conjunction with LASIK to improve both near and distance vision.

AAO spokesman James Salz, MD, clinical professor of ophthalmology at the University of Southern California in Los Angeles, said:

“It’s very safe and reversible. If we put it in and you don’t like it, we can take it out.”

The Kamra cornea inlay costs about $5,000 to $7,000, which is around the same price as LASIK. The procedure is already available in Europe, Asia, and South America, and makers AcuFocus are hoping to receive FDA approval for the U.S. market sometime next year.

Findings were presented at the annual meeting of the American Academy of Ophthalmology.
