A 62-year-old man from Mumbai with a history of hyperopia and thick lens presents with intermittent episodes of blurred vision and mild eye discomfort over the past 2 weeks. On examination, the anterior chamber is shallow, and gonioscopy shows appositional angle closure in the superior and temporal quadrants without any synechiae. Intraocular pressure is 22 mmHg in both eyes. Anterior segment OCT confirms narrow angles bilaterally. What is the most appropriate next step in management?
