Patients with low eye pressure after glaucoma surgery usually need about 1-2 months to recover gradually. Having glaucoma surgery does not mean that glaucoma can be cured. Patients need to undergo regular checkups and pay attention to the changes in intraocular pressure, nerve fiber layer thickness and visual field. If postoperative patients have low intraocular pressure, it may be caused by wound leakage, etc. They should cooperate with ophthalmologists to repair the wound as soon as possible and control the intraocular pressure, and the normal intraocular pressure can be restored in about 1-2 months. If the patient has low intraocular pressure after glaucoma surgery, it is recommended that the patient should go to the ophthalmology department of the regular hospital in time for review and follow the doctor’s instructions for treatment. Postoperative patients should also do a good job of eye care, strictly according to the doctor’s instructions for medication, to avoid postoperative infections, etc., which will help control the intraocular pressure.
