Enucleation is the enucleation of the eye while leaving the eye muscles and remaining orbital contents intact.
The eye is removed due to a number of eye tumors, including in eyes that have suffered trauma or severe blow, and in eyes that have lost the ability to see, causing pain. This is because eye excision is usually performed under local anesthesia. This anesthesia around the eyes is similar to the anesthesia performed in dentistry. A strong anesthetic will be given into a vein so that the patient does not feel anything. Also, local anesthesia will be injected behind the eye, its effects usually last about 12 hours. After local anesthesia, the level of intravenous sedation will be reduced. However, it will be maintained to reduce the patient's anxiety during the surgery.
The surgeon measures the dimensions of the eyeball, the length of the optic nerve, and the horizontal dimensions of the cornea, so he draws the eyeball before opening it. A dissecting microscope will be worn in order to detect the main features and possible tiny lesions. Therefore, the eye opens with a sharp blade, holding the eyeball with the left hand.
The eye removal operation is performed as a back-to-front diffusion motion, and the surface of the incision begins on the side adjacent to the optic nerve and ends at the end of the cornea. The area of ??the incision depends on the detection of a lesion. Otherwise, the ball will be cut along a horizontal plane.
