Surgery on the eyeball usually does not leave a scar. Surgeries on the eyeball generally include laser surgery and eyeball decompression surgery as follows: 1. Laser surgery: Under computer control, the part of tissue to be removed from the corneal stroma layer under the flap is accurately photobursted and vaporized by a laser, so that the tissue is removed without superfluous scars. 2. Eye decompression surgery: artificially improve the drainage channel of atrial fluid to restore the normal circulation of atrial fluid. Surgical procedures include laser iridectomy, trabeculectomy, implantation of glaucoma drainage valves, and cycloplegic cryotherapy. All of these eye surgeries do not involve the connective tissues around the eye, and are only performed on the globe of the eye, so they do not leave scars. Eyeball surgery should also pay attention to pre-operative examination and eye cleaning, regular follow-up and rest after surgery, avoid spicy food and infection.
