Red eyes after strabismus surgery normally subside in about 1 month. It is possible to have red eyes after strabismus surgery, usually due to a postoperative inflammatory response and subconjunctival hemorrhage. Postoperative inflammatory reaction is related to the irritation of the surgery itself, while subconjunctival hemorrhage is related to the rupture of small blood vessels at the site of the surgical incision, both of which will gradually diminish over time until they disappear, a process that usually takes about 1 month. Patients can order hormonal eye drops to reduce the postoperative inflammatory reaction, such as the commonly used tobramycin dexamethasone eye drops, etc. For subconjunctival hemorrhage, warm towels can be used to apply hot compresses 48 hours after surgery to promote its absorption. If you experience discomfort after strabismus surgery, you should seek prompt medical attention.
