High intraocular pressure one year after glaucoma surgery can be treated with intraocular pressure-lowering medication under the guidance of a doctor, and surgery can be considered if medication is ineffective. High intraocular pressure one year after glaucoma surgery may be caused by surgery failure or other eye diseases. Patients can be treated with intraocular pressure-lowering eye drops, such as Brinzolamide eye drops and Hirschsprung’s base eye drops, under the guidance of the doctor to relieve eye discomfort. If the eye pressure is not controlled by medication, patients can choose to have another surgical treatment, such as trabecular meshwork resection. It is recommended that postoperative glaucoma patients follow the doctor’s instructions for care, regular checkups, and timely consultation when discomfort occurs.
