Introduction
In general, whether a patient can see clearly after glaucoma surgery depends on individual circumstances. Patients whose optic nerves were not severely damaged before surgery and whose intraocular pressure was promptly controlled usually maintain or even improve their vision after the procedure. However, for those who already had optic nerve atrophy and severe vision loss prior to surgery, postoperative improvement in vision is typically limited. After surgery, patients must strictly follow medical instructions regarding medication and avoid rubbing or bumping the eye. It is important to keep the eye clean and prevent infection.
Generally, whether a patient can see clearly after glaucoma surgery depends on individual circumstances. If the optic nerve was not severely damaged before surgery and intraocular pressure (IOP) was controlled in time, vision can usually be maintained or even improved postoperatively. However, if optic nerve atrophy and severe vision loss were already present before surgery, visual improvement after surgery is typically limited. A detailed analysis is as follows:
If glaucoma is detected early, with elevated IOP but no significant optic nerve damage, timely surgical intervention to control IOP can preserve normal light transmission pathways. Vision usually remains at preoperative levels, and some patients may experience reduced blurriness due to lower eye pressure. Regular postoperative monitoring of IOP is necessary to ensure stability.
If glaucoma was uncontrolled for a long period prior to surgery, persistently high IOP may have caused optic nerve atrophy and impaired retinal photoreceptor function. Even if IOP returns to normal after surgery, the existing vision damage is often irreversible. In such cases, the main goal of surgery is to prevent further vision loss rather than to improve vision.
After surgery, it is essential to strictly follow medical instructions regarding medication and avoid rubbing or bumping the eye. Maintain good ocular hygiene to prevent infection. Eat a light diet, avoid spicy and irritating foods, and control fluid intake.
