What is vitrectomy surgery?
Vitrectomy surgery is an advanced form of eye surgery that is performed in the operating room under a microscope. It is often used to treat conditions such as retinal detachment, macular pucker, macular hole, vitreomacular traction, diabetic retinopathy, vitreous hemorrhage, dislocated cataract/lens implant, endophthalmitis, and uveitis. Vitrectomy may take thirty minutes to several hours to perform depending upon what task is being accomplished. Despite common tales, the eye is not taken out and placed on the cheek. It remains in its normal position throughout the surgery. Vitrectomy may be performed under general anesthesia to avoid pain and to avoid eye movement during surgery. During vitrectomy, tiny needle-like incisions are made to enter the white of the eye to gain access to the central core of the eye, which contains a gel called vitreous. Various instruments no larger around than needles are placed into the small incisions to perform tasks such as peeling or cutting membranes from the retinal surface, cauterizing blood vessels, removing blood or inflammatory debris from the eye, and applying laser. The surgeon views the tips of the instruments through the dilated pupil with an operating microscope. Sometimes, a gas bubble or silicone oil is placed in the eye to hold the retina in position to heal properly.
What type of anesthesia is available?
Although some surgeons and patients choose local anesthesia, general anesthesia is also available. With local anesthesia the patient is sedated with IV medication so there is no memory of the anesthetic injection around the eye. Surgical drapes are placed over the face leaving plenty of breathing room. During surgery the patient is awake, but generally does not feel pain. It is important to lie still on the operating room table as movement during surgery may result in damage to the eye and affect the final visual result.
General anesthesia offers some advantages over local anesthesia. With general anesthesia the patient is motionless and remembers nothing of the surgery. The anesthesiologist places a tube to hold the airway open. Which type of anesthesia is best for a patient may be determined by the health of the patient, so you may wish to ask your internist for advice. If a person cannot lie still for the surgery or if claustrophobia is a problem, general anesthesia is preferred. Although there are risks with any type of anesthesia, modern techniques offer a high degree of safety for the patient.
How can I prepare for vitrectomy surgery?
Your retinal specialist may schedule an appointment with your primary care doctor if evaluation is needed prior to surgery. Please inform your doctor of any chest pain or pressure, fever, productive cough, or shortness of breath. Unless otherwise notified by your doctor, do not take aspirin-containing products or any herbal supplements for two weeks prior to surgery. Coumadin may be stopped four days prior to surgery. On the morning of surgery, take no medications for diabetes unless instructed differently by your doctor, but please do take all of your other medications with a sip of water. Otherwise, do not eat or drink anything after midnight the day before surgery. If you usually use eye drops in the morning, they may be taken on the morning of surgery.

What are the risks of vitrectomy surgery?
Although uncommon, problems such as bleeding and infection may arise from any surgery. Retinal detachment or abnormal scar tissue formation may require additional surgery. Rarely, there may be loss of vision/loss of the eye. The most common problem following vitrectomy surgery is progression of cataract. Although serious problems are not encountered often, the risks and benefits must be weighed for each individual prior to surgery. For many eye problems, vitrectomy surgery is the only way to improve vision or prevent blindness.
What can I expect after vitrectomy surgery?
A soft eye patch and a hard eye shield are placed on the eye at the end of surgery. Leave these in place until your exam on the day after surgery. You may use Tylenol or Advil for aching pain, but call the doctor for a prescription if your pain is not relieved. It is not common to have severe pain after vitrectomy surgery. A scratchy feeling may result from sutures on the white of the eye. These sutures dissolve in about three weeks. At your exam after surgery, you will be given eye drops and/or an ointment to keep the eye comfortable, to prevent infection, and to promote healing. Wearing the eye patch is optional after you are seen in the office, but you may wear the hard protective shield as needed to prevent trauma to the eye. Depending upon the reason for your surgery, it may be very important to lie face down or on either side after your surgery. Be sure you understand any positioning requirements given by your surgeon and feel free to ask about special pillows and equipment available to help maintain head position. If a gas bubble is placed in your eye at the time of surgery, you may not fly on a plane or undergo nitrous-oxide anesthesia until the gas has dissolved, or you could risk severe pain and blindness. You may see the gas bubble as a horizontal, dark, curved line or as a dark ball in the vision. If a gas bubble is used during surgery, please keep a MedicAlert bracelet on your wrist until the gas has disappeared. The vision usually returns slowly over days to weeks after surgery, but may take many months for final recovery. The swelling and redness slowly disappear over weeks to months.
