Eye surgery, sometimes called ocular surgery, is a cosmetic surgery done on the eye itself or some of its associated adnexa, usually by an optometrist. The eye is a delicate organ, which needs extreme attention during, after, and during a surgery to prevent or minimize further damage to it. This delicate eye structure has many nerves that send signals from the eye to various parts of the body, including the brain, see this link for more details. When damage occurs, the vision of the eye can be severely impaired, leading to impairments to normal activities.
For in-depth treatment of the eye, several major operations are performed under general anesthesia, including the removal of eye tissue to be tested for eye disorders; the replacement of a minor defective muscle; and a procedure to raise the eyelid in a natural position when the patient has drooping eyelids. The doctor also removes any foreign objects that might irritate the eyes or cause inflammation. A plastic surgeon’s scalpel is used to perform most eye surgery, although other instruments such as an eyelid pump and a microkeratome blade can also be used. Eyelid surgery can be done under general or local anesthesia, depending on the extent of the treatment required. Most patients are in a recovery phase within one to three days, but occasionally additional time is needed.
General anesthesia is generally used in routine eye surgery. Some instances, however, require for it to be performed under a special anesthesia, such as those involving the removal of the iris or any other part of the eye. When the procedure is done under general anesthesia, precautions are taken not to induce a state of shock to the patient. General anesthesia is often associated with a risk of infections, especially when removing some body components, but such precautions are carefully considered before surgery. General anesthesia is required for all laser eye surgery procedures under most conditions, especially those that involve the removal of the iris, the middle ear or the retina. Patients who have undergone refractive laser eye surgery under general anesthesia have a lower risk of complications than those who have undergone it under a regional or local anesthesia.
Before surgery, the patient must be properly informed about the risks and complications involved in the planned treatments. Eye surgeons discuss such matters with their patients in detail and monitor their progress carefully through an ongoing correspondence. A qualified eye surgeon and a licensed physician anesthesiologist should be consulted when planning either a general or local anesthetic for eye surgery. General anesthesia involves a low dose of the anesthetic agent, typically sedation. This type of anesthesia can pose some risks such as confusion, breathing problems and possible side effects such as headache, fatigue, sweating and drowsiness. In order to avoid these problems, the physician will usually recommend using a low-dose of a sleep drug, benzodiazepine, tranquilizer or anti-anxiety medication in addition to the eye operation.
Eye specialists also discuss the complications that can arise in eye surgery for various eye disorders. Some of the more common disorders include myopia, hypermetropia or nearsightedness, astigmatism and presbyopia. For nearsightedness, the most common treatment option is to use bifocals or a reading lens with a high order. For people who suffer from farsightedness, LASIK eye surgery may be an effective option, click here to learn more about this surgery.
Some people wear contact lenses or glasses to correct their vision. For these individuals, the best option may be to remove and replace their glasses or contact lenses. Many eye surgeons offer the procedure known as vitrectomy to permanently remove unhealthy tissue and replace it with prosthetic or custom-made vision correction lenses and prosthetics. For individuals who no longer require glasses or contact lenses, LASIK eye surgery may be an effective option to improve their vision. Other eye surgery procedures may be recommended by eye specialists to help preserve your eyesight through age or to treat other vision impairments such as glaucoma.
