• STAB Incision Glaucoma Surgery - SIGS Description: SIGS or Stab Incision Glaucoma Surgery is a new technique that I described and is a guarded filtration surgery. It acts via filtration through an intentionally compromised sclero-corneal tunnel. This surgery has advantages of only a single 2.8 mm cut in the conjunctiva, complete elimination of subconjunctival dissection and a greatly reduced risk of failure secondary to sub-conjunctival scarring which can occur in conventional trabeculectomy and all other related procedures which involve creating a limbal or fornix based conjunctival flap. Surgery is easier, faster.and less traumatic and flap related complications are minimized. Virgin conjunctiva is maximized and the bleb is created not by scissor dissection but by a more physiological hydrostatic expansion of sub-conjunctival spaces and drainage channels, all of which are intact.
