In the field of ophthalmology, the use of corneal inlays has been employed typically to correct age-related nearsightedness or presbyopia, which is a condition and die affects more than 1 billion people around the glow. Recently, A new device called the KAMRA inlay that employees the same principles as a corneal inlay, was used by researchers to improve near vision "without impairing far distance vision" that is often associated with traditional inlays.
In general, the conventional corneal inlays that are being used today may produce some complications including haziness of vision.
New designs have been developed to minimize this effect, but doctors mostly prescribes steroids to manage clouded vision. The more extreme cases, Cordele inlays maybe removed with surgery.
When the KAMRA inlay, researchers have found an effective "solution that truly delivers near vision that transitions smoothly to far distance vision." The device is a thin, flexible ring with A 3.8 mm diameter and a 1.6 mm hole in the middle. Researchers say that the inlay asked like the crevice of a camera, helping the eye to adjust its depth perception thereby enabling near and far vision at the same time.
During the research, the team found that this type of corneal implants allowed over 80% of the presbyopic patients to see better, with progressively improving vision that is checked periodically over a follow-up period. Reportedly, patients were able to gain up to 2.9 lines on a basic reading chart and results showed constant improvement.
The KAMRA inlay is still classified ads and investigational device within the United States and is awaiting approval by the FDA. However, the device is already available in South America, Asia, and Europe where they are now used commercially to improve vision.
