A stereoscopic eye measurement system and method for measurement of corneal characteristics, anterior chamber depth and lens characteristics in a single acquisition. The system and method use a stereoscopic camera configuration to capture the images of IR pupil, of the intersection of a structured illumination pattern with the cornea and lens, and of the Placido reflection off the cornea. The projection pattern may be a cross pattern, a dot array, a dot+cross pattern, or a starburst pattern. The system uses a large pupil in order to obtain images of the lens. The system uses different focal points to achieve the best images of corneal topography, corneal layering and lens surfaces and a combination of corneal topography, corneal layering, pupil and the lens.
