Stepping up to 4.5mm, this Bores O‑Z marker sits in the mid‑range of the refractive marking set, stamping an optical‑zone ring large enough for standard ablation centration. The smooth handle and 102mm straight stainless‑steel shaft give the thumb a stable point of contact, and the polished face transfers ink cleanly to the corneal surface.
Features & Benefits
- 4.5mm ring spans the mid optical zone for refractive layout
- Smooth handle stabilizes the thumb against the corneal apex
