Principle of Cutting
Carriazo-Pendular is based on the principle of convex
applanation of the cornea, protecting the center during the cut.
Drop-and-Go: advantageous quick coupling of suction ring and
cutting head in front of the patient's eye (facilitates surgery on
patients with deep-set eyes).
The cut can be initiated immediately after the bilateral coupling
(drop) of cutting head and suction ring.
“Pendular” – Motion of cutting head
The ball-shaped surface of the Carriazo-Pendular microkeratome cutting head molds the cornea.
This distributes the pressure primarily to the centre of the eye and protects the corneal centre
during the cut.
