Examinations

We take the eye examination procedure very seriously and therefore allow a full 30 minutes for your appointment as this allows our optometrist to ensure a complete health check on your eyes together with providing the best possible spectacle or contact lens prescription. All the functions of the eye examination are individually performed by your qualified optometrist, not a clinical assistant. We also have close connections with ophthalmological specialists at King’s College Hospital should further clinical investigations be required.

Nidek 1 (300x289)

Nidek Computerised Test Equipment

We are equipped with the very latest test room equipment from market leaders, Nidek. The Auto-Refractor, Test Chart and Phoroptor are all interlinked and “talk” to each other. All functions are controlled remotely by the optometrist allowing for seamless and highly accurate eye examination.

Henson Web

Field Analyser

Manufactured by Henson, it assesses the sensitivity of the retina across the central 60 degree of the visual field. It is able to detect subtle changes that might otherwise go unnoticed. During the test, lights of varying intensities appear in different part's of the visual field and the perception of these lights is charted and the pattern created allows the Optometrist to make a diagnosis of any potential problems.

OCT

Optical Coherence Tomography 'OCT'

Optical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section pictures of your retina. This allows the optometrist to gain a clear picture of any abnormalities that may have been noticed during the routine examination. Furthermore, it is very useful to be able to compare the results from previous visits to ascertain any changes in previous pathology.

Slit Lamp

Slit Lamp

The slit lamp is an instrument consisting of a high intensity light source that can be made to project a thin beam of light into the eye. This results in a magnified 3D view of the various parts of the eye allowing detailed examination. The Optometrist is able to see the clear, outer covering (cornea), the lens coloured part (iris) and the front section of the gel-like vitreous that fills the eye. Special lenses can be placed between the lamp and the eye to view deeper structures of the eye such as the optic nerve and retina.

Pulsair Tonometer

Tonometer

In order to ensure a person’s optic nerves are healthy, it is important to check the pressure that is placed on them by the fluid in the eyes. This is known as the intraocular pressure.

The instrument we use to check this pressure is called a Pulsair Tonometer and it is a simple, quick and painless procedure.

Subjective Refraction

The most important part of correcting vision is the process of refraction which determines the level of correction that a patient requires. Firstly, a retinascope or auto-refractor is used to obtain a baseline. Then subjective refraction takes place which should be familiar to anyone who has ever had their eyes tested. Here, the optometrist adjusts a series of corrective lenses to achieve the best visual acuity whilst viewing a variety of charts.
