Optical Coherence Tomography (OCT)
The OCT machine enables non-invasive examination of the posterior structures of the eye by using reflections of light to provide a cross-sectional image. It is a diagnostic device which aids in the detection and management of ocular diseases.
We use our OCT machine frequently to monitor macula or optic nerve disease in our patients. By comparing the structure and thickness of a patient’s scan against a normal, healthy eye, pathology can be detected, even at early stages.
Humphrey Visual Field Analyser (HVFA)
The HVFA reveals the extent of a patient’s peripheral vision. It can expose early stages of a disease and is used for the following:
- Diagnosis of an ocular disease. In particular, Glaucoma, as this displays characteristic patterns of visual loss.
- Assessment of neurological disease causing visual loss.
- Monitoring the progression or recovery of ocular and neurological disease.
- Drivers who are 75 years of age or older, require a field test as part of their RTA form. The purpose of the field test is to rule out the presence of significant visual field loss, and therefore confirm whether they are fit to drive.
The IOL Master is a modern, non-contact machine used for taking measurements of a patient’s eye in preparation for cataract surgery. These measurements are used to calculate the suitable type and strength of the new intra-ocular lens which will replace the natural lens during surgery. It is considered as the “gold-standard” machine for pre-operational eye measurements. Every eye is unique, and it is important to obtain measurements as accurately as possible, so that a patient can achieve the best possible outcome for their vision.
The slit-lamp consists of an adjustable beam of bright light and a high magnification microscope for the examination of the anterior (front) and posterior (back) parts of the eye, as well as being able to measure the Intra-Ocular Pressure (IOP) of each eye. The Slit-Lamp is a vital tool which you will find amongst all ophthalmic practices.
Similar to the OCT machine, the Spectralis is a non-contact, tomography machine, which takes detailed scans of the layers of the macula and optic nerve. It can detect early pathology, and here at our Kotara clinic, we use it during our Angiography procedures. See Angiography.
Fundus Fluorescein Angiography
Fundus Fluorescein Angiography is a diagnostic procedure, used to examine the blood vessels of the retina. Fundus angiography is often performed to confirm the initial diagnosis of a patient with retinal/macular disease.
The Verion is an advanced machine which assists with our pre-cataract surgery measurements. It provides information about the positioning and alignment of the new lens (IOL) by selecting the optimal incision locations for cataract surgery. It is particularly useful for patients who require a Toric IOL for correction of their Astigmatic refractive error.
The Verion machine measurements are taken at our Kotara practice and the data can again be reviewed later in the Charlestown Private Hospital surgical theatre at the actual time of surgery.
Atlas 9000- Corneal Topography
Our Atlas Topography machine is a non-contact device used to detect corneal pathology and also to measure the curvature of the cornea as part of our pre-operative cataract work-ups.
