Generally the operation of circumcision will not involve the eye, while circumcision is local anesthesia, local anesthesia, due to the limited effect of anesthesia, usually does not occur in the eye side effects. Therefore, eye swelling after circumcision may be caused by ophthalmic diseases. Swollen eyes can be a result of conditions such as allergic conjunctivitis, eyelid inflammation, keratitis, and overuse of the eyes. This is usually done in conjunction with a medical history, for example, allergic conjunctivitis usually has allergens such as dust and feathers, inflammation of the eyelids usually has conditions such as unclean eye habits, and keratitis usually has a history of wearing keratoscopes and trauma to the eye. To summarize, patients are advised to visit an ophthalmologist for an examination. A combination of their symptoms and the results of the examination will determine the cause of the disease.
