The Optical Zone Markers offers clear, atraumatic landmarks during complex ocular procedures, making it a reliable choice for ophthalmologists looking for accurate corneal centration and alignment.

Features:

  • Atraumatically marks and cleanly divides corneal epithelium with trephine‑sharp edges.
  • Can be used with or without ink.
  • In PRK, sharp edges seat at Bowman’s membrane to contain alcohol.
  • Facilitates accurate, precise capsulorhexis creation.
  • Single‑piece crosshair design enhances centration and alignment.
