Breakthrough Surgical Technology for Presbyopia

September 25, 2012 (PRLEAP.COM) Health News
Surgeons at the Bochner Eye Institute are proud to be one of the first centres in North America to offer patients the clinically-approved Kamra inlay for presbyopia. This breakthrough technology has received clinical approval in Canada after over 10 years of research and development, completed clinical trials in Europe, Asia, and United States, and over 15,000 inlays inserted worldwide.

The Kamra inlay is a microscopic black ring with a tiny aperture or hole in the centre creating a pinhole effect. The small aperture increases the depth of focus to enhance near objects and maintains distance vision. The inlay is inserted in the non-dominant eye beneath a LASIK flap or pocket to enhance reading vision.

"This technology allows our patients to have a minimally invasive, simple corneal procedure for presbyopia," says Dr. Raymond Stein, Medical Director, Bochner Eye Institute. "The corneal inlay can be performed at the same time as the LASIK procedure or in patients that have previously had LASIK or PRK."

The inlay has a diameter of 3.8 mm with a central opening of 1.6 mm and a thickness of 5 microns. This thickness is 1/10th the thickness of a human hair. There are over 8,400 microperforations in the opaque part of the disc to allow proper nutritional flow within the cornea of glucose, oxygen, and other metabolites.

"Clinical indications also include pseudophakic patients with a monofocal implant" says Dr. Albert Cheskes, Medical Director, Bochner Eye Institute. "The Kamra inlay will allow our past and new cataract patients the option of enhanced reading vision". "Unlike with other presbyopic procedures the Kamra inlay can easily be removed."

"The Kamra inlay is so simple in principle but with such a dramatic effect in its ability to enhance reading vision" says Dr. Albert Cheskes. "The outcomes and safety profile of the procedure have been excellent, accounting for why so many ophthalmologists around the world have personally undergone the procedure to enhance their own reading ability," says Dr. Raymond Stein.

The procedure is relatively easy for patients to undergo. Under topical anesthesia a femtosecond laser is used to either create a LASIK flap or pocket in the cornea. The Kamra inlay is then inserted over the visual axis using a sophisticated alignment system. Reading vision is typically enhanced to the J1 or J2 level.

Patients need a comprehensive assessment to determine eligibility for the Kamra inlay. Not all patients will be candidates for the procedure. All refractive surgery consultations are complimentary at Bochner Eye Institute.

Over 80 Years of Patient Care, Education, and Research
Bochner Eye Institute is a tertiary eye-care facility that was founded by Dr. Maxwell Bochner in 1929 and devoted to providing leading-edge technology and excellence in patient care. The surgeons were among the first in North America to offer laser vision correction, corneal crosslinking, topography-linked PRK for
irregular corneas, phakic implants, and cataract surgery in a government approved free-standing facility. The surgeons have written over 35 textbooks and hundreds of scientific articles.
