The aim of the procedures is to enhance the normal outflow of aqueous via the conventional and uveoscleral pathways without the formation of a filtering bleb. The Trabektome, the Eyepass and the Glaukos iStent require access to SC trough the trabeculum and can be combined with phacoemulsification which by the removal of a bulky cataractous crystalline

Combined phaco-canalostomy provides slightly better hypotensive effect and less antiglau‐ coma drops than canalostomy alone [103,104]. Compared to trabeculectomy it offers lower but not statistically significant hypotensive effect and requires more antiglaucoma medication than trabeculectomy [105].
