The KAMRA™ corneal inlay from AcuFocus® provides a novel solution for presbyopia. As previously noted, Will Vision and Laser Centers is one of only 30 centers in the United States selected by the manufacturer to implant this revolutionary optical advance. The KAMRA® inlay restores everyday vision so you can see text messages, a computer screen, the time on your wrist watch and the price on a price tag at the supermarket without the constant frustration of reading glasses or contact lenses. It provides a natural range of vision – from near to far – without blurry zones. In addition, because it does not need to be updated or changed as you age it can help to provide clear near vision over time.
The KAMRA® corneal inlay is an ultrathin aperture made from biocompatible polyvinylidene fluoride and carbon that is surgically placed within the cornea in the non-dominant eye. It is 5 microns thick with an outer 3.8 mm diameter and a central 1.6 mm aperture. The ring has 8400 laser etched holes to facilitate diffusion of aqueous, oxygen and nutrients through the cornea. Once implanted, it provides a full range of vision from near to far by markedly increasing the depth of focus for the eye. The brain combines the distance and near images together and provides a full range of vision. The KAMRA™ inlay can generally be implanted in any patient, including those that have previously undergone a laser vision correction procedure.
With the KAMRA™, unlike monovision, there is no loss of distance vision in the implanted eye. As a result, the person can enjoy natural everyday vision with the ability to focus from near-to-far. In addition, because the KAMRA™ inlay works by altering the depth of focus of the eye it does not need to have its power adjusted with age. As a result, the KAMRA™ inlay provides the most long-lasting vision performance of any presbyopia solution.

How the KAMRA® Corneal Inlay Works
The KAMRA® inlay is an ultra-thin circular disk with an aperture in its center that is perfectly sized to enhance the depth of focus and near vision for the human optical system. It is markedly thinner and smaller than a soft contact lens (see image below). Once placed within the tissues of the cornea it focuses all light from both distance and near objects onto the retina.
The KAMRA® inlay is implanted in only one eye. This allows the person to see up close while maintaining excellent distance vision in both eyes. When working together, the eyes allow the person to see from near-to-far in a continuous manner. In comparison, monovision, which corrects one eye for near and one eye for distance does negatively affect the distance vision in the eye that is set for near.
Once implanted into the cornea, the KAMRA® inlay blends in with the normal pupil coloration and does not create any negative cosmetic effect. In addition, the KAMRA® inlay does not affect the ability to perform eye examinations or eye surgery should a patient develop cataracts later in life.
