The injection is a mixture of essential medicines to treat the disease. This is injected directly into the eye close to retina.
This procedure is done at the eye clinic and treated carefully as a surgery, although it is not a complicated one. Ophthalmologist gives anesthetic medications to make the eye numb, sterilizes for disinfections, holds open the eyelids, and injects the medicine using a needle through the white part of the eye to back side of it. This full procedure might only take around 2 to 5 minutes.
A very clean room is chosen for this procedure, in order to avoid infections. The space is cleaned and sterilized just before the procedure. Some Ophthalmologists prefer doing it in an operation theatre but this is not always the case because this procedure is simpler and can be done outside. At global eye clinic we do it in Operation theatre thus nullifying risk of infection. There will be number of bright lights and you will be required to lie down on a comfortable bed.
These injections control the leakages from the blood vessels within the eye. These can also discontinue the development of abnormal tissues that block and blur the vision. Certain injections function as anti-inflammatory medicine to fight against any infection inside the eye.
To treat macular degeneration, this treatment is required may be once a month till the disease is treated. These patients may also require lifetime observation and return to the treatment if the symptoms repeat.

Your doctor will perform a complete eye examination before he gives you the injection. You should mention everything about your past or present health problems, any medicines you take and any allergies for you.
Use all the medicines and eye-drops as specified by the specialist. Visit the specialist as required by him for follow up examinations. If you feel very uncomfortable with the eye seek for urgent attention by your doctor. No special care is required after Intra-vitreal injections and one can resume routine an hour after surgery.
After an injection, you might feel little bit of pressure in the eye, grittiness, irritation, blurred vision or little bit bleeding or redness on the white part of the eye. If they are within few days of the procedure, it can be considered as normal. These feelings improve over the days. Keeping your relaxed and using artificial tears with the opinion of the doctor might help reduce these complications.
The complications occur only for one or two of 1000 injections given, which is a very small percentage. You do not need to fear because the doctors take all possible precautionary actions to avoid complications.
