CA 2744332
Systems, apparatus, and methods are disclosed for locating tissue layer transitions within a cornea, including focusing a laser to a laser spot with an energy below a photodisruption threshold of the cornea, varying a position of the focal spot of the laser between an anterior surface of the cornea and a posterior surface of the cornea, and determining one or more transitions of the tissue layers based on a change in harmonic light generated by the laser spot.
L'invention porte sur des systèmes, un appareil et des procédés pour situer des transitions de couche de tissu à l'intérieur d'une cornée, comprenant la focalisation d'un laser vers un point laser avec une énergie inférieure à un seuil de photocautérisation de la cornée, la variation d'une position du point focal du laser entre une surface antérieure de la cornée et une surface postérieure de la cornée, et la détermination d'une ou de plusieurs transmissions des couches de tissu sur la base d'un changement de lumière harmonique générée par le point laser.
