Abstract
The present invention provides a system and associated method for advantageously treating bodily tissue containing collagen, such as ophthalmic tissue. The treatment includes providing a pattern of heating to which the tissue is to be exposed and the exposure of that tissue to shrink collagen therein. In ophthalmic applications, the pattern includes at least one region that corresponds to an ocular region of from about 4 mm to about 20 mm radially from the optical axis. The shrinkage of collagen within this ocular region improves accommodation for near vision. The present invention thus provides an effective treatment for the ocular condition of presbyopia.
