Thornton Low Profile Optical Zone Marker, 3mm, 1.5mm Ring Height, Beveled To Outside, Round Knurled Handle, Dull Finish, Overall Length 3-1/8" (80mm)

This low‑profile Thornton optical zone marker is scaled to 3mm with reduced ring height of 1.5mm for precise marking in dense cataracts and corneal topography procedures. The compact beveled tip and streamlined profile minimize obstruction of the surgical field. A knurled handle and dull finish support secure grip and reduced glare during extended refractive marking.
