In terms of surgical management of astigmatism, it is imperative to premark the eye with the patient sitting vertically to avoid cyclorotation. It is imperative that the patient’s visual axis and that of the surgeon are in proper alignment, or the marks will not be aligned along the proper corneal meridians. Our patented system allows a surgeon stereo visualization yet with monocular visual axis alignment without the risk of cross-fixation.
