Bores O-Z Marker, 3mm Diameter, Smooth Handle, Overall Length 4" (100mm)

This Bores O‑Z marker imprints a 3mm reference circle on the corneal surface to define the optical zone during refractive procedures. The smooth handle gives steady fingertip orientation as the marker is centered over the visual axis. A 100mm overall length keeps the instrument balanced through ink application and pressing.
