    What is a cataract?

    A cataract is a clouding of the natural lens within the eye. It is not a growth, film or tumour and does not cause any pain or discomfort of the eye.

    Once a cataract starts to form, it will progressively continue to cloud over causing gradual loss of vision in the affected eye. The rate of progression varies from person to person.

    What are the symptoms of cataract?

    The most common symptom is gradual blurring of vision. Other symptoms may include: glare, change in colour perception, double vision (in the affected eye) and difficulty driving at night.

    When should a cataract be treated?

    Cataracts seldom require an emergency procedure. The most common reason to consider surgery is when the distance vision becomes hazy with your best distance spectacles. If your best corrected vision is insufficient for driving purposes, then cataract surgery is encouraged if it is likely that the vision will improve with surgery.

    What is cataract surgery?

    The aim of cataract surgery is to improve your vision. The surgery involves removing the hazy natural lens and replacing it with a small plastic lens. The procedure is usually performed under local anaesthetic and can take between 10-30 minutes surgical time.

    Is the procedure done with a laser?

    Traditionally, cataract surgery is done with a fine ultrasound probe which emulsifies the lens which is then aspirated. New laser technology is available which “pre-treats” the eye prior to proceeding with surgery. This makes the procedure slightly more precise and slightly safer. The visual results are the same as traditional cataract surgery. The eye surgeons at Armadale Eye Clinic have access to and use the laser during cataract surgery if requested.

    Will I need to wear glasses after the surgery?

    Prior to surgery, we measure the eye to see what would be the best lens to insert in your eye in order to provide you with perfect distance vision. This is achieved in the majority of cases. Most people require reading glasses after bilateral cataract surgery for fine print. New technology is available where the inserted lens allows you to see in the distance and near without glasses, however, these can result in haloes post surgery but are a good option to consider if you would lie to be “glasses free” after the surgery.

    What are he risks associated with cataract surgery?

    Like all invasive procedures, cataract surgery has risks. Any complication can have an affect on the final visual outcome. These complications include:

    Infection in the eye or endophthalmitis (Risk 1:1000 per operation)
    Loss of lens material into the back of the eye (would require a second procedure)
    Failure to achieve the desired refractive outcome (you may require spectacles to see perfectly in the distance)
    Retinal detachment.

    What does the procedure involve?

    After admission to the day surgery centre, you will be introduced to your anaesthetist who may give you some “calming medication”. Eye drops will be inserted in the eye to be treated. You will then have the laser pre-treatment if you have elected to o so. Then you will be escorted into the main theatre for the actual procedure.

    The eye will have a patch on after the procedure and you will have to leave the eye pad on until you are assessed by your surgeon the following day.

    WHAT IS A CRVO? A vein occlusion is a blockage of one of the blood vessels that drain the blood away from the retina at the back of the eye. Blockage in a retinal vein causes a build-up of pressure in the vein, and this results in leakage of fluid into the retina causing swelling Continue Reading

Cataract assessment:

1) A-Scan

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.

Macular Degeneration:

1) OCT

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.
