Crafted with Dr. Jaime Velazquez O'Byrne, M.D., Colombia's input, this marker features 4 radial blades that trace the horizontal and vertical meridians of the visual axis. Internal marks assist in verifying IOL alignment post-surgery. A central 5.00 mm ring acts as a guide for Capsulorhexis, while the outer ring safeguards the blades. The angled shaft prevents lower eyelid contact.
