For years doctors and scientists, alike, have been trying to come up with the perfect solution that would eliminate the need for glasses and contact lenses. In one of the most recent studies by the American Academy of Ophthalmology the end of reading glasses may be near, as researchers have found a way to hopefully end long-sightedness in those over the age of 40.
It is said that more than one billion people suffer from long-sightedness that is age related. This problem is known as presbyopia, which often occurs in people over the age of 40. As a result, many who have never worn glasses before, are forced to wear glasses in order to see for reading, driving and other things that require a close-up view. The problem is, however, that fixing it requires eye surgery and not everyone is willing to participate.
The American Academy of Ophthalmology said that the researchers who were in charge of the project did have many who were willing to participate for the trial of such surgery. 507 patients were tested at random, all between the ages of 45 and 60. These patients were worldwide and have been followed up on for the last three years. In their studies they said 83 percent of those who tried the surgery had success in improving their vision without disturbing other types of vision like the ability to see far away. The scientists on the case said that in a previous study many had a disturbance with their vision, including haziness and decrease in ability to see far away.
But now, what is being called the KAMRA inlay, is under clinical review. The KAMRA inlay is a thin ring that measure 3.8 millimeters in diameter and features a hole int he middle that measure 1.6 millimeters. The ring is inserted into the cornea of the eye and so far, only lasts 3 years, according to sources. The surgery is said to be quick and painless, as it requires only a topical anesthesia and lasts only 10 minutes. The research was presented at the annual meeting of the American Academy of Ophthalmology and will be further evaluated.
In the last several years there have been three corneal implant inventions created to solve the same condition and all of these methods are still under review by the Food and Drug Administration. Some of the corneal implant surgeries, featured by the American Academy of Ophthalmology, are the ACI 7000, the InVue, and the PresbyLens. All of these methods are different millimeter diameters, as well as different depth, and all of them currently have warnings on them, stating that it could change parts of a person’s vision. Many of these methods can also be combined with Lasik surgery to achieve the desired result.
The KAMRA inlay will continue to be reviewed by the American Academy of Ophthalmology to determine its success at reducing the number of patients who need reading glasses. Though this method of surgery, and the problem it is suppose to correct, will not completely get rid of the use of glasses and contacts, researchers are hopeful that will one proven method there could eventually be many more. Many other researchers continue to work on finding ways to get rid of the need for glasses and contacts, altogether.
