Influence of Selective Laser Trabeculoplasty (SLT) on the iStent inject® outcomes. Kaplan–Meier survival plot for eyes without SLT treatment prior to surgery (black) and eyes who had insufficient response to 360° SLT treatment previous to surgery (grey) with success defined as sufficient final intraocular pressure without additionally surgery. Secondary glaucomatous surgery had to be performed in 21.2% in group A and in 21.4% in group B due to insufficient IOP lowering-effect after MIGS (p = 0.788)
