Sklar Anis Radial Marker, 4mm
A 4mm radial marker used to imprint guide lines on the cornea for incision alignment, available in 8, 12 and 16 inch lengths. It is a standard item in professional surgical instrument trays.
The Sklar Anis Radial Marker is an ophthalmic marking instrument used to imprint radial guide lines onto the corneal surface, helping the surgeon plan and align incisions accurately during procedures such as astigmatic keratotomy or other refractive and cataract surgery steps where precise radial orientation matters.
Its marking blades are set at a 4mm width, giving a consistent, repeatable guideline pattern each time the marker is applied to the eye. This listing offers three length variants of the same marker, at 8, 12 and 16 inches, likely reflecting handle length options that suit different surgeon preferences for reach and control during the marking step.
Accurate corneal marking supports predictable surgical outcomes in procedures where incision placement relative to the visual axis or astigmatic axis directly affects the result. Refractive and cataract surgery centres performing procedures that rely on precise incision placement typically keep a radial marker of this kind as a standard preoperative marking instrument.
