Sistema de posicionamiento de haz preciso en cirugía ocular

摘要

An apparatus (10) for ocular surgery includes a delivery system for generating and guiding a surgical laser beam (13) to a focal point (20) in a treatment area of an eye (22). Additionally, a contact device (24) is employed for using the eye to establish a reference datum. Further, an optical detector (32) is coupled to the beam, path of the surgical laser (12) to create a sequence of cross-sectional images. Each image visualizes both the reference datum and the focal point (20). Operationally, a computer (34) then uses these images- to position and move the focal point (20) in the treatment area relative to the reference datum for surgery.
