Totally reliable and totally accurate with Topcon’s Rotary Prism Measuring System, the advanced rotary prism principle is able to obtain highly reliable data. The off-centered ring target is able to measure areas previously occluded by a small pupil. The prism angle enables a much wider fundus area to be measured. Accordingly, the measurement image provides extremely reliable data.
