Selective laser trabeculoplasty is now more widely used than ALT. It is believed to create less collateral damage while achieving effects comparable to those of ALT. In studies of patients with primary open-angle glaucoma, SLT has been found to lower IOP by 6 to 8 mm Hg, with 70% of patients showing an improvement after the procedure. [52, 53]  Although its use in PKPG has not been specifically studied on a large scale, reports of its effective use in treating PKPG have been noted [54] ; however, similar to ALT, the IOP-lowering effect of selective laser trabeculoplasty tends to decrease over time.
