The KAMRA® Corneal Inlay, used at Crystal Clear Vision, is a treatment for presbyopia which uses "small aperture optics", or the "pinhole effect", the same principle used by the “F-stop” of a camera to increase depth of focus, to help you reduce your dependency on reading glasses.

It is a small, donut shaped disc, which measures 3.8mm in diameter, with a central opening of 1.6mm. The inlay is only 5 microns thick, which is thinner than a red blood cell.

Tiny holes throughout the inlay help assist the natural nutrient flow system in your cornea. The KAMRA® Corneal Implant is made from polyvinylidene fluoride, or PVDF, which is a material that has been used safely for cataract implants in the eye for decades.

Once it is inserted by Dr. Machat, the KAMRA Inlay™ is difficult to see with the naked eye and is virtually invisible. It is placed within the corneal stroma, the body of the cornea, directly in front of the pupil.

As we age, the lens inside the eye becomes less flexible, and we lose our ability to focus on near objects. The central light rays entering your eye are more focused than peripheral light rays, which can blur your vision if your lens is unable to focus the light. The KAMRA Inlay™ blocks these peripheral light rays, allowing only the focused central rays to enter the eye.

By blocking the light rays that can blur your vision, the KAMRA Inlay™ can provide a clearer image at a much wider range of distances. This allows you to see at near, and intermediate, without compromising your distance vision.

Dr. Machat had the procedure in the Summer of 2012 at the age of 50, and no longer depends on readers for the newspaper, his blackberry, checking price tags, or any other near tasks.

Although the KAMRA® implant is only in Dr. Machat’s left eye, his eyes feel balanced and natural at distance when driving, when checking emails at his computer screen and when reading a medical journal. He remains unaware which eye is doing the work for each task.
