What to expect on admission to hospital

You will be welcomed at the hospital and shown to the ward where you will be settled in. A nurse will carry out routine investigations including checking your pulse and blood pressure. The nurse will also record details of any medications you are taking and ask questions about your general health. Once this has all been completed the nurse will instil the drops which dilate your pupil in readiness for the operation.

The Ophthalmic Nurse will come to see you to explain what will happen during and after the operation and to answer any further questions you may have.

You will be asked to sign a consent form to state that you have been provided with, and understand all the information given relating to the operation (including the risks and benefits of surgery) and that you agree to the proposed treatment.

You will be taken to the operating theatre in your own clothes, so it is important to wear something comfortable.

What happens during surgery?

The procedure to treat this condition is called vitrectomy.

Vitrectomy means removal of the vitreous, the jelly-like substance that fills the eye behind the lens. This is a necessary part of the treatment for a number of conditions affecting either the retina of the eye or the vitreous itself. In your case, vitrectomy simply removes debris to give light a clear passage to the retina.

Surgery is usually carried out under local anaesthesia which involves gently injecting anaesthetic around the eye. The anaesthesia will numb the eye and allow it to remain still during the procedure. You may be offered sedation if you are particularly anxious, which will help you relax whilst the procedure is carried out. You will be awake during the operation and will be aware of some movement and touch, but the procedure will be painless.

You will be made comfortable on the operating couch, following which the skin around your eye will be thoroughly cleansed and a sterile cover (“drape”) will be placed over your eye and face. The cover will be lifted off your mouth so you can breathe and talk easily. Your eyelids will be gently held open, although they will feel closed.

You will see little of what is happening during surgery, but we will explain what we are doing as the operation goes along. The Theatre staff will make sure you are comfortable and help you relax. Someone will be there to hold your hand if you wish. The operation usually takes about forty-five minutes, but in some cases may take longer.

Surgery is performed with the aid of an operating microscope and special lenses which give the surgeon a clear image of the vitreous and retina.

Three tiny incisions are made in the sclera (the white of the eye) to enable instruments to be passed into the vitreous. The first of these is a saline infusion (a “drip”) to replace fluid in the eye, maintaining the pressure and therefore the shape of the eye during surgery; the second is a fibre-optic light to illuminate inside the eye; and the third is for the operating instrument, starting with a vitrectomy cutter which enables safe removal of the vitreous gel from inside the eye.

Once the surgical procedure is completed the vitreous is replaced with a salt-water solution into which the eye secretes its natural aqueous fluid.

Traditionally the three scleral incisions are sutured at completion of the operation, but with the finer instruments now available most patients will benefit from a “sutureless” technique, with self-sealing incision sites.
