Final answer:
The eye may water and itch after surgery due to inflammation, irritation, or allergic reactions. Infections like conjunctivitis or blepharitis can also contribute to these symptoms, requiring medical treatment to alleviate discomfort and prevent complications.
Step-by-step explanation:
The eye may water and itch for several weeks after surgery due to a number of reasons, including post-surgical inflammation, tissue irritation, or allergic reactions to substances used during or after the procedure. After ocular surgery, there is a natural healing process, which can involve inflammation and irritation of the eye tissues, potentially leading to symptoms such as watering and itching. Additionally, if the patient has an allergic predisposition, the exposure to allergens or reaction to medications could exacerbate these symptoms. Moreover, complications like infections can also cause prolonged symptoms of watering and itchiness. Known infections such as conjunctivitis or blepharitis may occur, characterized by inflammation and discharge. Treatment for these symptoms typically involves the use of medications to reduce inflammation and treat any underlying infection.
