Background: The refractive outcome of glaucoma operations principally their influence on astigmatism, aren’t completely explained. Objective: to evaluate corneal topographic changes following sub-scleral trabeculectomy (SST) versus non penetrating deep sclerectomy (NPDS) in cases with primary open-angle glaucoma (POAG). Patients and Methods: 30 eyes of 30 cases were allocated into 2 similar groups...
