Biometry is the measurement of the various dimensions of your eye.
Patients booked for cataract surgery must have their eye measurements taken first. This will allow us to work out the intraocular lens power needed to give you the best vision possible. We generally don't need to make contact with your eye.
OCT is an imaging technique that can be used to detect and diagnose many eye diseases.
OCT uses infrared light rays to measure the micro-anatomy of eye structures. Snapshots are taken at different depths and the lines then combine to create a cross-sectional image. The 3D imaging allows improved diagnosis of pathology and changes over time by providing vivid illustrations of retinal and optic nerve structures.
OCT is used for diagnosis and follow-up of the following conditions:
Perimetry is a very important clinical tool for measuring central and peripheral visual field function. It is a threshold test involving quantification of visual sensitivity.
Ultra-wide retinal photography is a useful tool for documenting conditions in the fundus, including peripheral lesions.
Fluorescein angiography is an investigation used to look for abnormalities in your retina, such as diabetic retinopathy, age-related macular degeneration or retinal vein occlusion. It involves injecting a fluorescent dye into your bloodstream to highlight the blood vessels in the back of the eye.
