Cutting edge shape that takes into account the corneal diameter
By changing the tip opening angle with 4.6 mm and 5.0 mm, the length from the cutting edge to the maximum width is aligned. It allows for making safer incisions.
Sharper Cuts with a Double Bevel
Emphasized sharpness to create an incision needed for graft insertion with a single perforation. Excellent sharpness was achieved by making the angle of the blade sharper and making it a double bevel.
