Eyeball removal surgery involves anesthesia, cutting and separating the conjunctival tissue, cutting the extraocular muscles and optic nerve, removing the eyeball and closing the conjunctival incision. Eyeball removal surgery is commonly used to treat intraocular tumors, absolute stage glaucoma, and atrophy of the eyeball. An anesthetic drug, such as lidocaine hydrochloride, is injected into the eye to numb the patient’s pain nerve fibers. The conjunctival tissue is then cut and bluntly separated along the corneal limbus. The six extraocular muscles are exposed and clipped separately and the optic nerve is clipped so that the eyeball is completely free and removed. The procedure is completed by closing the conjunctival surgical incision with sutures. Patients who wish to undergo eyeball removal surgery need to visit the ophthalmology department of a regular hospital and be examined by a doctor to decide whether surgery is necessary.
