OCT-guided femtosecond laser surgical module for anterior eye surgery [73]. (A) The two modalities were coupled using a dichroic mirror prior to the scanning mirrors and shared an objective and the contact lens (B) used to deliver light to the surgical site. (C) OCT volumes were used to detect the various tissue surfaces and allowed the surgeon to precisely position the laser cutting pattern and avoid damage to the iris and surrounding structures. (D) Iris camera image denoting the edge of the laser cutting pattern (1) and the pupil boundary determined on OCT (2).
