    “…We present a novel calibration method for a multi-view laser Doppler speed sensing (MLDSS) system. In contrast with the traditional method where only the laser geometry is independently calibrated, the proposed method simultaneously optimizes all the laser parameters and directly associates the parameters with a motion sensing model. …”

    “…Such complications may occur during continuous curvilinear capsulorhexis (CCC), lens fragmentation and intraocular lens (IOL) implantation. Femtosecond laser-assisted cataract surgery (FLACS) devices, such as the LenSX (Alcon Laboratories) are advantageous because they can detect the area and largest point of zonulopathy via anterior segment optical coherent tomography (AS-OCT) before the manual part of the procedure. …”
