Introduction to SubCyclo

SubCyclo® is a new nondestructive laser procedure for the treatment of glaucoma.

Based on the transcleral cyclophotocoagulation principle, it relies on the 810 nm SubLiminal® stimulation of the ciliary body, producing the aqueous humour, and the uveoscleral pathway, secondary route of the aqueous outflow.

This procedure can be performed thanks to the combined use of the Quantel Medical Supra 810 laser and the Quantel Medical SubCyclo® probe.


Tip of the probe positioned at 3 mm posterior to the limbus. Probe perpendicular to the eyeball. Laser treatment delivered by moving the tip of the probe in a continuous sliding motion:
– from 9:30 to 2:30 (superior quadrant)
– from 3:30 to 8:30 (inferior quadrant)
