Henderson Alignment Marker

The Henderson Alignment Marker features a semi-circular ring with three blunt prongs for impressing landmarks at the 3, 6 and 9 o'clock positions. The 0.5mm flattened tips are easily inked to provide clearly defined dots at the 11mm optic zone. Blunt tips prevent damage to the epithelium, even if the patient inadvertently moves and the handle is mounted at a 45 degree angle allowing for an easy approach to the patient's eye.
