Our Technology

At Metwest Eye Centre we use the best technology to achieve the highest and most accurate of results, such as:

Diagnostic Technology

OCT

Optical Coherence Tomography is the one of the latest technologies that takes a topographical map of the back of your eye using laser scanning techniques. Depending on the area that your Ophthalmologist wishes to concentrate on, the test can look at your macula, optic disc or general retina. An OCT scan can monitor changes in macula degeneration, macula hole, and the nerve fibre layer that is effected in conditions such as glaucoma. Conditions such as diabetic macular oedema and vein occlusions can have their treatment determined by the findings of an OCT.

Fundal Photography

It is quite common for your Ophthalmologist to want photos of the back of your eye. Often, one of the Orthoptists (or assistants) will do this. The photographs help your doctor to monitor the back of your eye and the different structures within it, so that they compare the photo with your eye at your next visit. The photo will often show your optic disc and your macula, two important structures at the back of your eye – feel free to ask questions about what you see in the photo.

MetWest Eye Centre has two retinal cameras to investigate the back of the eye.

The Canon retinal camera takes photos of the macula and optic disc, with the ability to focus in on these areas in fine detail, important in macular degeneration and glaucoma.

The Optos Wide-Field Camera takes a wide-field image of the retina – encompassing the macula and optic disc as well as over 200o of the retinal periphery. This is particularly helpful in patients with diabetic retinopathy, peripheral lesions such as naevi or melanoma and for picking up vein occlusions in the peripheral retina.

Both cameras have the ability for fluorescein angiography. The Optos Wide-Field Camera also can take auto-fluorescence images – helpful in diagnosing conditions such as Central Serous Chorio-retinopathy and Polypoidal Choroidal Vasculopathy.

IOLMaster

The IOLMaster is the gold standard in optical biometry – measuring the length of the eye, distances between structures and the power of the cornea at the front of the eye. These measurements are then loaded into calculations required for determining intraocular lens power. The IOLMaster is both to assist in determining the type of lens to be used during surgery as well as the power of the lens. It utilises laser to accurately measure distances between the cornea at the front of the eye and retina at the back of the eye.

FLUORESCEIN ANGIOGRAMS

A fluorescein angiogram is a yellow dye test used to detect changes and abnormalities in the retina. The dye is injected into your arm and once in the blood stream is able to be photographed in the vessels that are in the back of your eye. Fluorescein Angiograms are used in conditions such as diabetic retinopathy and macula degeneration.

Humphrey Visual Field test

This is a test for your side vision. Many different eye conditions, such as glaucoma and optic neuritis can affect your peripheral vision as well as your central vision. Field tests reveal if there is any loss of side vision which is often not detected because we normally use our central vision. It is common to have to repeat visual field tests on a regular basis to check if there has been any change. Field tests take approximately 30 minutes to complete.

Pachymetry

This is a test to measure the thickness of the cornea (the front surface of your eye). It is important for diagnosis of glaucoma as it helps us to predict the ideal pressure for your eye.

Corneal topography

Corneal topography is a measured of the curvature / power of the front of your eye. Topography determines if the curvature is regular or irregular – and can be used in analysing astigmatism and ectasias of the cornea such as keratoconus.

B-scan

A B-scan is an ultrasound of your eye and its contents. It can be helpful in the diagnosis of conditions such as retinal detachment, and in the monitoring of some changes in the eye. Your eye is closed during the b-scan, and the doctor scans through your eyelid to look at the inside of your eye.

Technology for Treatment

Lasers

These procedures are performed in the consulting rooms at MetWest Eye Centre.

Yag Capsulotomy

After lens insertion during cataract surgery, the new lens that has been inserted into your eye can have a membrane that can slowly reduce your vision. This is not another cataract that requires surgery. The membrane can be taken away with laser – a painless procedure that does not usually need to be repeated.

Yag Iridotomy

In patients with narrow angle glaucoma, an iridotomy can be performed to and reduce the risk of attacks of angle closure. A small hole is made in the iris to increase the drainage of fluid.

Selective Laser Trabeculoplasty (SLT)

This type of laser is performed on patients with glaucoma. The laser is used at a very low level and treats specific cells in the trabecular meshwork. This laser can be safely repeated.

Argon Laser

Argon laser is used to specifically target areas of the retina. It can be used for different conditions such as diabetic retinopathy and vein occlusion.

Minor Procedures

At MetWest Eye Centre we have a dedicated Minor Procedure room which is used for procedures such as chalazion removal, probing of tear ducts, removal of sutures and some excisions. Your Ophthalmologist will decide whether or not your individual condition is suitable for treatment in the Minor Procedure room or requires the use of our dedicated onsite Day Surgery.

Hyfrecator

MetWest Eye Centre has a hyfrecator, used for removing lashes that grow in towards the eye. This is a permanent solution to mis-directed eyelashes.
