Blurred vision after glaucoma surgery may be caused by diseases such as keratitis and dry eye after surgery, which can be treated with medications such as Pranoprofen eye drops under the guidance of your doctor. 1. Keratitis: It is usually due to infection after glaucoma surgery, causing symptoms of keratitis and blurred vision. Keratitis may also cause loss of vision, foreign body sensation, itching and other symptoms, which can be treated with medicines such as Pranoprofen eye drops and Levofloxacin Hydrochloride eye drops under the guidance of doctors. 2. Dry eye: Mostly due to the production of filtration vesicles in the eye after the operation, changing the shape of the eye surface, resulting in uneven distribution of tears, which leads to dry eye and blurred vision. Dry eyes may also have symptoms such as fatigue, itchy eyes and foreign body sensation. It can be treated with medications such as hydroxyglucagon eye drops as prescribed by your doctor. Blurred vision after glaucoma surgery should be avoided by avoiding excessive eye use, paying attention to rest, and participating in outdoor activities appropriately.
