The surgical success rates of the 3 procedures for PKPG (ie, trabeculectomy with mitomycin-C, GDD surgery, cyclodestructive procedure) in controlling the IOP to less than 21 mm Hg are similar (70-75%).

The prognosis for graft survival is not clear. The lowest incidence of graft failure follows trabeculectomy (10-20%), as compared with GDD surgery (10-50%) and cyclodestructive procedures (20-50%); therefore, the long-term prognosis for graft survival appears to be 40 to 60% in patients with PKPG.

More data are needed to determine long-term success and prognosis for graft survival with minimally invasive glaucoma surgery treatment. [81]
