Ganciclovir is an antiviral medication that is used in an implant that is inserted into the eye during surgery. This implant is used to treat a serious condition called (CMV) cytomegalovirus retinitis in patients who suffer from AIDS. This drug will not cure this eye infection, but it can help to prevent the symptoms from worsening.
After your eye has used up all the medication from the implant (typically within a five to eight month period) the implant is removed via surgery and, at the same time, if required, another implant can be given.
All three elements of this process, the implant containing the medication, the surgery or the medicine itself can cause some serious side effects, including eye infections, the formation of cataract or the detachment of the retina. Before you take this implant, you should discuss with your doctor about the good elements of this medication and process as well as the associated risks.
This medication is only available via prescription from your doctor. This drug is available in the dosage form: implant.

It's extremely important that your doctor or healthcare professional monitors your progress at regular checkups. This is to ensure that the medication is working as it should be and to spot any issues with the implant, surgery or medication itself. These checkups will also assist the doctor in determining when all of the medication in the implant is used, so it can be removed and replaced if necessary.
You may notice decreased or blurred vision in the eye where the implant has been placed. This can last for two to four weeks after the surgery, and it is expected, so don't be alarmed. You should let your healthcare professional or doctor know if your vision becomes worse or these symptoms last longer than four weeks. You should also let them know if you discover any other changes in your vision as this could be a sign of complications from the surgery.
Allergies You should let your doctor or healthcare professional know if you have ever suffered from an allergic reaction to this medication before, or to similar medications. It's also important to make them aware of any other allergic reactions you may suffer from, such as to animals, foods, dye or preservatives.
