Do both eyes undergo surgery for glaucoma?

In general, whether both eyes require surgery for glaucoma depends on the condition of each eye. If both eyes show significant disease and meet surgical indications, surgery is needed for both; if only one eye is affected or the other eye remains stable, usually only the affected eye requires surgery. Detailed analysis is as follows:

If both eyes are affected by glaucoma, with persistently elevated intraocular pressure (IOP) that cannot be adequately controlled with medication, or if there is progressive optic nerve damage, then surgical intervention is required for both eyes. Surgery creates a new aqueous humor drainage pathway, effectively lowering IOP in both eyes, preventing further vision loss, and comprehensively controlling disease progression.

If only one eye is diagnosed with glaucoma and the other eye appears normal upon examination with no risk of developing the disease, surgery is only necessary for the affected eye. If the fellow eye has mild involvement that can be managed with medication to stabilize IOP and slow disease progression, surgery may be deferred. Regular follow-up examinations are sufficient to monitor disease changes and avoid overtreatment.

In daily life, it's important to develop healthy visual habits—avoid prolonged viewing in dim lighting and control visual workload. Strictly adhere to prescribed medications, have regular IOP measurements, and undergo fundus examinations. Maintain emotional stability and avoid sudden emotional fluctuations that could cause sharp increases in IOP, thereby supporting long-term disease stability.
