Abstract
In various embodiments, a laser is scanned across biological tissue to alter the characteristics of the tissue. To alter the optical characteristics of a cornea, the laser is scanned in an annular pattern over a region having a ratio of the outer diameter of the region to the inner diameter of the region. The laser may also be used to irradiate cartilage in joints to treat osteoarthritis.
