There are no exact statistics on how long glaucoma surgery lasts, and the exact time that glaucoma surgery lasts is generally related to the type of glaucoma, the severity of the condition, the type of surgery, the age of the patient, and the control of the intraocular pressure after surgery. For patients with closed-angle glaucoma, if the condition is mild, found in time, and the patient’s atrial angle function is good, the glaucoma surgery results are good, and the results of the surgery can generally be maintained for a longer period of time, even more than 10 years. However, if the patient’s condition is complicated and treatment is delayed, the effect of glaucoma surgery is generally poor, the intraocular pressure is unstable after surgery, and the effect of surgery can be maintained for a shorter period of time. It is recommended that glaucoma patients seek timely medical attention to assess their condition and follow the doctor’s instructions to choose the appropriate treatment.
