Pterygium patients are discharged from the hospital approximately 3-5 days after surgery and usually take 2-3 weeks to return to normal. The cause of pterygium is complex, but it is usually caused by fibrous tissue growth in the conjunctiva of the lid with blood vessels growing into it, which can lead to corneal astigmatism, redness of the eyes, vision loss, and aesthetics. Surgery is currently the most effective treatment and does not usually recur after surgery. After pterygium surgery, the corneal epithelium is often repaired in 2-3 days, with some patients recovering in a day. The stitches can usually be removed after 7-10 days. Until the sutures are removed, patients will have a foreign body sensation in their eyes and will be prone to tearing, so it usually takes 2-3 weeks to fully recover. In addition, post-operative patients need to follow medical advice for treatment, timely use of eye drops and regular eye examinations to ensure eye safety.
