What are intravitreal injections?
Intravitreal injections are injections of medication given directly into the eye, specifically into the jelly-like centre called the vitreous.
They are commonly used to treat retinal conditions such as macular degeneration, diabetic eye disease, and retinal swelling, delivering medicine exactly where it is needed.
The procedure is quick, performed under local anaesthetic, and most patients feel little to no pain.
The procedure is routinely performed by an ophthalmologist (eye specialist), or a trained nurse injector.

Avastin (Bevacizumab)
Avastin is a medication that helps reduce leakage and swelling in the retina by blocking abnormal blood vessel growth. It is widely used and effective, and although it was originally developed for cancer treatment, it is safely prepared for eye use.
Eylea (Aflibercept)
Eylea is designed specifically for eye conditions and works by blocking substances that cause fluid leakage and abnormal blood vessels. It often lasts longer in the eye, meaning some patients may need injections less frequently over time.
Lucentis (Ranibizumab)
Lucentis is an eye-specific medication that treats retinal swelling and abnormal blood vessels. It has been used for many years and has a strong safety and effectiveness record.
Vabysmo (Faricimab)
Vabysmo is a newer treatment that targets two pathways involved in retinal disease, helping control swelling and blood vessel growth. For some patients, it can allow longer gaps between injections while maintaining good vision.

You will lie back in a comfortable reclining chair and your eye will be numbed with drops so you do not feel pain.
Your eyelids are gently held open, the eye is cleaned, and the injection is given in a few seconds, usually felt as slight pressure.
Afterwards, the eye may feel a little gritty or sore for a short time, and you can usually go home the same day. You may use topical lubricating drops for comfort.
