OCT is a technology that produces high resolution cross-sectional images of structures in the eye. It relies on the different light reflectivity of each layer of tissue as it scans, to give us a microscopic look. It is used by ophthalmologists to look at the retina at the back of your eye, or in our case, to study anterior eye structures such as your cornea and iris (coloured part of the eye).
Since the wavelength used by OCT is very near infrared, it is safe for repeated use on human tissues including the eye. It is one of the best non-invasive, three dimensional imaging techniques available today.
You will be seated in front of a machine and asked to look at a target. Nothing touches your eye at any point and you can blink as much as you need. It is very similar to taking a picture of the back of your eye. The test only lasts a few seconds.
