Patent ID: 7217266

Claim:
A method of using a feedback control to non-invasively identify and locate one or more subsurface targets based on predetermined conditions for selective laser treatment at a tissue surface area, comprising the steps of: a) identifying the location of the one or more subsurface targets in the tissue surface area by: i) directing one of a polarized and an unpolarized light having a predetermined wavelength at the tissue surface area; ii) detecting one or more reflections of said light using a multi-dimensional photo-sensor; iii) measuring one or more characteristics indicative of the physio-chemical properties for each of the one or more subsurface targets by automatically analyzing the reflections detected by said photo-sensor and comparing the analyzed reflections with the predetermined conditions, said predetermined conditions defined at least in part by one of predetermined image analysis and one or more mathematical treatment algorithms relating to features of an image; and b) treating the one or more subsurface targets identified during the identification step by automatically applying a laser of a predetermined wavelength and a predetermined power to the one or more subsurface targets in accordance with the one or more characteristics; and c) automatically adjusting one or more parameters of the laser in real time in accordance with the one or more characteristics until treatment is complete.
