OCT – New dimensions in eye care

3D eye scanning technology is now available in conjunction with a normal eye test for a maximum cost of just £10, thanks to investment in the latest imaging technology by Specsavers for the local community.

An Optical Coherence Tomography scan (commonly referred to as an OCT scan) produces a structural scan of the back of the eye. The results are similar to an MRI or CT scan in that it creates multiple scan slice images. The OCT machine uses a totally safe, laser light source and not x-ray type radiation.

An OCT scan allows us to examine the structures of the eye in more detail than ever before, including layers of the eye that would not normally be visible using traditional methods. This helps identify early signs of conditions, including age-related macular degeneration and glaucoma, years earlier than traditional imaging methods.

By using light particles to achieve detailed images of the back of the eye, this diagnostic technique transforms the early detection and therefore treatment of eye conditions including: wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.

Given that nearly half of all sight loss is preventable*, the sooner we can detect these conditions, the sooner we can help manage them. To do this, OCT images will be stored on file so the optometrist can help note changes over time – a real benefit to the monitoring of overall eye health.

What is it like?
Fast, painless and non-contact, the scan is performed on hospital grade equipment. It does not include any puffs of air, and takes place in seconds.

The scan will be in addition to a thorough eye test with an optometrist during which they will use appropriate clinical tests and procedures to measure vision acuity, as well as taking an overview of the health and functioning of the eyes.

OCT scans are additional to normal eye tests and can be requested when booking appointments or on arrival in store. The cost of the scan (£10) will be added to the customer’s final bill. Customers entitled to a free NHS eye test will need to pay the additional £10.
