Near Vision Correction

KAMRA™ Inlay Near Vision Correction

Near Vision Correction Corneal Inlay Dimensions

The AcuFocus KAMRA™ corneal inlay is a device designed to correct near vision in patients with age-related farsightedness. The device is very small, measuring just 3.8 millimeters in diameter with a central opening of 1.6 mm, and only 6 microns thick (not even 1/10th the thickness of a piece of paper). Dr. Eva Liang was the first female ophthalmologist in the country to perform the procedure.

Who is eligible for Near Vision Correction?

The KAMRA corneal inlay is intended for patients who’ve become frustrated with their dependence on reading glasses to perform near tasks. A patient’s eligibility for the procedure can only be determined by an ophthalmologist after a comprehensive eye exam.

The best way to determine your eligibility for the KAMRA Inlay is to visit our office for a comprehensive eye exam. The specifications of your eye will help our team determine your candidacy for this new procedure.

Specifically, the KAMRA Inlay is approved for presbyopic patients aged 45-60 who have prescriptions of +.50 D to -0.75 D (meaning they have practically no refractive error) with a near correction need of +1.00 D to +2.50 D of reading add.

How does it work?

The KAMRA inlay is designed to block certain light rays that ordinarily would not be focused correctly by the presbyopic eye. The device is implanted just beneath the surface of the cornea. It acts like the aperture of a camera, using a pinhole effect to focus incoming light. This increases a patient’s depth of focus and thus allows clear vision at all distances — near, intermediate and distance.

What is the procedure like?
During the KAMRA procedure, a pocket is created in the center of the cornea, where the device is inserted. The inlay is placed in the non-dominant eye only. The procedure takes less than 15 minutes. Sutures are not required, and only topical anesthesia, in the form of eye drops, is used.
