Marker assures consistent sizing, shaping and placement of superficial flap for Viscocanalostomy procedure. Cross hatches are 1.0mm away from corneal side of marker or 4.0mm away from apex. Marker is used to outline superficial flap of viscocanalostomy. After conjunctiva is retracted, sclera is examined for collector channels and marker is placed between two channels with cross hatch marks at limbus. Apply with pressure to globe for 15 seconds, remove and examine mark to ensure placement is positioned properly. If placement is not optimal, sclera refills with blood after another 30 seconds or so and marker can be reapplied to correct position. Upon removing marker, outline is followed with mini diamond blade and sclera is cut down 200 – 250 microns. Marker assures consistent sizing, shaping and placement of superficial flap for viscocanalostomy procedure.
