Presbyopia (prez-bee-OH-peeah) is a common eye condition for many people as they enter their 40s. The symptoms include difficulty seeing near objects – such as newspapers and websites – while long distance vision remains fine.

It’s a natural result of aging. As the lens in the eye loses its elasticity, its ability to flex to focus on close objects as well as far away ones.

Until now, the way to address presbyopia has been reading glasses, monovision, LASIK or contact lenses. Now, there’s a more advanced option for restoring everyday near vision.

The KAMRA inlay treatment is a simple, reversible surgical procedure that corrects presbyopia and frees a person from the constant frustrations of reading glasses.

Smaller than a contact lens, the KAMRA inlay is a device implanted in the eye to treat presbyopia. The KAMRA inlay uses a principle similar to photography called depth of focus.

The benefit of this technology is a broader range of clarity of focus – near, far and in between. The KAMRA inlay is an opaque, circular micro-disc with a small opening (1.6 millimeters) in the center. It is much smaller than a contact lens and lighter than a grain of salt – the actual size is just 3.8 millimeters in diameter.

When placed in the cornea, the small opening in the center of the KAMRA inlay blocks unfocused light and allows only focused light to reach the retina. With focused light rays, you can enjoy a wider range of improved vision for all distances near, far and in between.

To get an idea of how the KAMRA inlay works, try this experiment:

Hold your hand up to one eye and close the other, then roll that hand into a tight fist.

Slowly open your fist until there’s a small tunnel of light through the middle.

Look through that tunnel at the words on this page. Sharper, aren’t they?

Try it with and without your reading glasses, and with and without looking through your tightened fist.

That’s the remarkably simple idea behind the KAMRA inlay.

Of course, the KAMRA inlay does not reduce your field of vision as your closed-up fist does. In fact, the inlay is able to restore near and intermediate vision while maintaining distance vision.

The KAMRA inlay can also be used in conjunction with LASIK eye surgery. This enables a correction to be made first for your distance vision, followed by the KAMRA inlay to correct your near vision.

With more than a decade of clinical research and development, the KAMRA inlay provides natural vision without compromise, it restores everyday near vision, reduces the need for reading glasses, revives computer vision while maintaining good distance vision, and works continuously for constant, long-term near vision rejuvenation.

The KAMRA inlay will not be suitable for everyone. A thorough eye examination is required to determine the best treatment option for your eyes.
