What are the Criteria for Candidacy?
Martin L. Fox, MD FACS
As an inevitable consequence of the aging process all individuals over the age of 45 years of age will eventually lose the ability to focus clearly at near. The frustrating condition, referred to as presbyopia, makes even the most common of visual tasks such as reading the newspaper, looking at a mobile phone or even a wristwatch nearly impossible. The fact is that no matter where we are or what we are doing there is always the need to read.
The FDA approved KAMRA Corneal Inlay is the first of its kind technology designed to correct for the loss of reading. It works by making use of small aperture or pinhole optics allowing only focused rays of light to enter the eye thereby producing an extended field of vision allowing for excellent vision at intermediate and near ranges without affecting the ability to see well in the distance. It is placed in the first few layers of the cornea of the non-dominant eye in a narrow pocket created by a precise femtosecond laser. The procedure is painless and takes 10-15 minutes for most recipients.
Best candidates for KAMRA are those who have lost the ability to see at near and are between the ages of 40 and 65 years with good distance vision and healthy eyes. Those with cataracts or a history of severe dry eye or glaucoma do not make for good candidates, however, following cataract extraction with a standard monofocal implant those with prior cataracts can qualify for KAMRA.
If you have problems with distance vision as well as reading, don’t despair! Farsighted individual can have custom laser vision correction at the same time as KAMRA as can near sighted individuals with lower prescriptions. Those who wear bifocal glasses or progressives with a higher degree of near sightedness can have the surgery performed in a stage manner with LASIK or PRK done first and KAMRA added after 3-4 weeks of postoperative healing. With KAMRA, those with both near and distance focusing problems can now have the opportunity of having all of their focusing issues address.
