An A-scan using the LENSTAR Biometer is performed on all patients in preparation for cataract surgery. The purpose of the scan is to determine the nature and strength of the intra-ocular lens required at the time of surgery in order to achieve the best optical result. This is one of the most important steps in achieving surgical excellence with cataract surgery.
2) Corneal topography:
A Toric lens is required at the time of cataract surgery if there is significant astigmatism in the eye which is to be operated on. The corneal topography helps confirm the strength and axis of the intra-ocular lens required at the time of surgery.
3) Cataract Surgery:
Our surgeons perform cataract surgery in a number of locations in Melbourne. All our cataract surgeons have access and use the Catalys Femtosecond laser for cataract surgery if required. We also use premioum intra-ocular lenses including toric and multifocal lenses if needed.

The OCT (Ocular Coherence Tomography) is a digital scanner used to assess the health of your macula. The scan is ultra-high definition and can detect the smallest change in your macula anatomy as can happen with Macular Degeneration. The scanner has the ability to save your scan and will be able to map any changes over time as it will recognise your eye and scan the exact same region of your nacula. The scan takes approximately 30 seconds per eye, it is painless and the pupil does not need to be dilated for the scan.
2) Fluorescein Angiography:
We have a digital angiography suite on-site at Armadale Eye Clinic. Angiography is often requires to look for leaking blood vessels in Macular Degeneration, Diabetes and other retinal vascular disorders. A fluorescent dye is injected into the vein and photographs taken. The test usually takes approximately 5 mintues, is painless and is well tolerated in most people. The results from the test are assessed on the spot and a diagnosis at the time of angiography. Earlier treatment is better in most cases of wet macular degeneration. We start treatment as soon as possible in patients presenting with wet AMD.
3) Intravitreal/ eye injections:
Eye injections are now commonly used to administer medications into the back of the eye/ vitreous cavity. This is a very effective way of delivering medication to the retina. The eye is disinfected, a local anaesthetic administered and the eye injected. The procedure is quick and relativeley painless. The eye feels scratchy after the injection and the vision is blurry for several minutes after the procedure. You should not drive after having an intravitreal injection in your eye.
