Delivering consistent results, the trephines are available in many sizes, from 2.5 - 18mm diameter.


Supplied sterile, the Corneal Punch System includes a Punch Piston and a Piston Holder and Base Plate, where a separately packed sterile and disposable Teflon corneal block fits. The Punch Piston is available in 5-7mm, 7-9mm and 9-11mm sizes and can also hold the Long Trephine Blades when used by hand as a punch to cut the cornea from the donor.

Two donor trephines are manufactured by Tecfen - with vacuum or without vacuum. The blades range from 6mm-9.5mm in diameter. Non-Vacuum Trephine Punches have four posts, ensuring proper alignment between the punch base and the trephine blade holder, delivering a perfect cut.
