What symptoms may occur after glaucoma surgery?

After glaucoma surgery, patients generally experience mild eye pain, increased eye discharge, temporary vision fluctuations, a foreign body sensation in the eye, and intraocular pressure fluctuations. Specific details are as follows:

1. Mild Eye Pain: Shortly after surgery, mild soreness or stabbing pain may occur due to surgical trauma. The discomfort is usually mild and tolerable, gradually diminishing as the wound heals. Severe pain or headaches are uncommon.

2. Increased Eye Discharge: A small amount of clear or light yellow discharge may appear post-surgery. This is a normal bodily response to surgical trauma. The discharge is typically thin and not accompanied by odor, redness, or swelling. Maintaining proper eye hygiene helps prevent accumulation that could impair wound healing.

3. Temporary Vision Fluctuations: In the early postoperative period, patients may notice slight vision decline, blurred vision, or visual distortion. These symptoms are often related to ocular edema or changes in intraocular pressure and are usually temporary. Vision typically stabilizes as the eye recovers.

4. Foreign Body Sensation: Patients may feel as though there is a minor foreign object in the eye, with a sensation similar to tiny particles rubbing against the eyeball—especially noticeable during blinking or eye movement. This is a normal part of tissue repair during wound healing and gradually resolves as recovery progresses.

5. Intraocular Pressure Fluctuations: Eye pressure may temporarily rise or fall after surgery. Elevated pressure might cause a feeling of eye fullness or pain, while low pressure could lead to mild discomfort or blurred vision. Doctors closely monitor pressure changes through regular check-ups and adjust treatment plans accordingly to restore pressure to normal levels.

Patients must strictly follow medical instructions for using eye drops, maintain good eye hygiene, and avoid rubbing the eyes. Immediate medical attention is required if severe eye pain, sudden vision loss, or increased discharge with an unpleasant odor occurs.
