Inclusion Criteria: * Adult patients scheduled to undergo DSLT treatment in one or both eyes. * Diagnosis of ocular hypertension or primary open angle glaucoma (POAG). * Medically controlled on 1-3 topical ocular hypotensive agents with IOP ≤21 mmHg. Exclusion Criteria: * Previous glaucoma surgeries/interventions: * Patients who have undergone prior glaucoma-related procedures (e.g., trabeculectomy, laser trabeculoplasty, MIGS, or tube shunt). * Patients who have undergone cataract surgery within the prior 2 years. * Secondary glaucoma: * Patients with secondary forms of glaucoma, such as angle-closure glaucoma, neovascular glaucoma, or glaucoma resulting from trauma or other systemic diseases. * Other significant ocular conditions including advanced cataracts, retinal diseases (e.g., age-related macular degeneration), or any condition that might complicate the assessment of intraocular pressure (IOP) or visual function as deemed by the investigator.
