As well as checking your vision and your prescription, the tests we'll perform on your eyes will help us gather the information we need to check that they're healthy and that there are no signs of eye disease.

This test will check your peripheral vision, and identify if there are any problems with any part of your visual field. If so, it'll determine if one or both eyes are affected, the extent of the problem, and what the chances are of it worsening.

This is a quick and painless procedure. The specular microscope captures high quality images of the back surface of the cornea, and checks for irregularities which may be early warning signs of a number of eye diseases.

An optometrist consultation is the first step towards corrective eye surgery. It's a very thorough eye examination which can take up to 2 hours. Some of the tests will be familiar to you already, but additional tests are conducted too. All the tests are painless.

Following the examination, your optometrist will interpret the results and compare them to the International Medical Advisory Board suitability guidelines, to determine your suitability for surgery.

This technology is used during your eye examination. It's a computer-controlled machine which identifies any issues your eyes have with focusing light accurately onto your retina. You'll look into the machine using two lenses, and be asked to focus on a picture while the auto-refractor calculates an approximate prescription using your ability to focus on an image.

This is a technique which maps the curved surface of the cornea. A 3D map of the eye helps your optometrist to assess any alterations in the shape of your cornea, and to diagnose various visual conditions.

This machine is the most advanced refractive laser system available today. 25 times more accurate than previous, similar laser systems, it can detect even the most subtle eye abnormalities, with the information used to customise the patient's laser eye surgery treatment.

Optical Coherence Tomography is an imaging test which is used in the diagnosis of many eye conditions. It uses light waves to take cross section images of your retina, allowing your optometrist to see its distinctive layers and measure their thickness and helping them to determine any issues.

A tonometer measures your eyes' intraocular pressure (IOP). It blows a gentle puff of air onto the surface of your eye, which flattens your cornea. The extent to which your cornea flattens is then used to calculate the IOP.

iScan is a personalised, state of the art eyecare report which uses advanced techniques to collate data, not only on the health of your eyes, but your general health too. The tests carried out include corneal topography (mapping the surface of the cornea), fundus photography (capturing a photo of the back of the eye), tonometry (measurement of pressure in the eye) and visual fields analysis. The results of the tests give detailed information the health, prescription and diagnostics of each eye.

Aberrometry is used to diagnose vision errors, represented by the way that the eye focuses light. The errors can be the more common lower-order (such as near-sightedness, far-sightedness and astigmatism) or higher-order, which are more complex.

This is a simple test which measures the thickness of your cornea, and it helps with diagnosing any eye conditions as corneal thickness can influence eye pressure readings. It helps the optometrist to understand your optical coherence topography reading.
