A method for focusing light comprising the steps of: (1) projecting at least one pulse of light onto a surface of the skin of a patient; (2) collecting at least a portion of the light that is reflected from the skin of the patient; (3) projecting the collected, reflected light onto a detector; and (10) adjusting the projection of the pulsed light onto the surface of the skin of the patient in such a manner that the signal projected onto the detector is optimized. When the pulsed light is properly focused, e.g., when it is characterized by the best focus, it can be used to provide energy to form an opening in the skin of the patient. When more than one pulse of light is required to form an opening in the skin of the patient, aligning the light prior to each pulse will improve the efficiency of formation of the opening.

Procédé servant à concentrer de la lumière et consistant à : (1) projeter au moins une impulsion de lumière sur une surface de la peau d'un patient; (2) recueillir au moins une partie de la lumière réfléchie par la peau du patient; (3) projeter la lumière réfléchie et recueillie sur un détecteur; (10) régler la projection de la lumière pulsée sur la surface de la peau du patient, de façon à optimiser le signal projeté sur le détecteur. Quand la lumière pulsée est concentrée correctement, c'est-à-dire caractérisée par la meilleure concentration, on peut l'utiliser afin de produire de l'énergie permettant de pratiquer une ouverture dans la peau du patient. Quand plus d'une impulsion de lumière est nécessaire pour pratiquer une ouverture dans la peau du patient, l'alignement de la lumière préalablement à chaque impulsion améliorera l'efficacité de la création de l'ouverture.
