Abstract
A method of treating a patient, includes providing a laser source for emitting a laser light, diagnosing an afflicted area of the patient, delivering the laser light to the afflicted area for at least one treatment cycle, the laser source being operable on the afflicted area at a level of 1 Joule/cm.sup.2 per treatment cycle, monitoring the afflicted area after the treatment cycle has been completed, and repeating the steps of diagnosing and delivering the laser light to the afflicted area based on the monitoring step. Each treatment cycle preferably has a duration of 33 seconds and the wavelength of the laser light is preferably between a range of 800-870 nm, and more preferably is substantially 830 nm.
Claims20
A method of treating a patient having an external skin layer, comprising the following steps:
- providing a laser source for emitting a laser light having a wavelength of between 800 nm and 870 nm;
- diagnosing an afflicted area of said patient, a portion of said external skin layer being adjacent said afflicted area;
- delivering said laser light to the afflicted area for at least one treatment cycle, said laser source being operable on said afflicted area at a level of 1 Joule/cm.sup.2 per treatment cycle so as to therapeutically treat said afflicted area and such that said external skin layer is not destroyed;
- monitoring said afflicted area after the treatment cycle has been completed;
- and
- repeating said steps of diagnosing and delivering said laser light to said afflicted area based on said monitoring step.
