Whether or not trabeculectomy can last a lifetime depends on a number of factors such as the patient’s specific condition, personal constitution, post-operative care, etc., and the exact duration varies from person to person. Some can last only a few months, some can last 2 to 3 years, and some can last more than 10 years or even decades. Trabeculectomy is the main surgical procedure for the treatment of glaucoma, and the duration of its effect is usually related to the severity of the disease, the individual’s physical condition, and the postoperative care, etc. Usually, the milder the disease, the better the individual’s physical condition, and the longer the postoperative care. The less severe the disease, the better the individual’s health, and the better the post-operative care, the longer the results will last. Some patients may have abnormalities such as machining and encapsulation of the filtering follicles within a few months, resulting in a re-escalation of IOP. Some of the filtering vesicles may lose their role 2 to 3 years after surgery, resulting in uncontrolled IOP. In other patients, the filtering vesicles still function well and the IOP remains well controlled for more than a decade, or even decades, after surgery. Whether or not a trabeculectomy lasts a lifetime varies from person to person. After trabeculectomy, it is important to follow your doctor’s instructions for care and to seek medical attention for any abnormalities.
