It involves an eye surgeon adjusting one eye (usually the dominant eye) for distance vision and the other eye for reading vision. It may at first sound like a strange concept, but the brain plays an important role.

What is Carpal Tunnel Syndrome What is Carpal Tunnel Syndrome. Carpal Tunnel Syndrome (CTS) is a condition caused by a narrowing of the carpal tunnel causing a compression of the structures within the tunnel, including the median nerve. This compression of the median nerve is what causes the uncomfortable symptoms of tingling, numbness and pain. The median nerve is the nerve that travels down the arm into the hand. With CTS, the nerve is squeezed as it passes through the narrow path (or tunnel) at the wrist.
