Specsavers in Chesterfield has just invested 50 000 in 3D scanning technology which allows optometrists to view the eye in more detail than ever before The Optical Coherence Tomography OCT machine which will be available for EOS appointments is a cutting-edge piece of equipment usually found in hospital eye departments It is used for a variety of functions including screening and management of conditions such as age-related macular degeneration glaucoma and diabetic retinopathy The technology produces a structural scan of the eye including layers of the eye that would not normally be visible using traditional eye testing techniques The results are similar to an ultrasound or MRI scan in that it creates multiple scan slice images that are built up to form a total image The OCT machine uses a totally safe laser light source and not x-ray-type radiation Chesterfields ophthalmic optician Allissa Charlesworth comments This investment gives our team the ability to enhance the services to the local community by identifying and helping to detect or manage conditions with a level of diagnostic capability which previously would have needed a hospital visit OCT technology produces such a detailed picture of the structures in the eye that it allows us to identify signs of diseases years earlier than traditional methods An example of this is glaucoma which the stores specialists are trained to spot Given that nearly half of all sight loss is preventable the sooner we can detect these conditions the sooner we can help manage them or refer people for treatment The scan will be in addition to a thorough eye test during which the optometrist will use a range of clinical tests and procedures to measure the quality of someones vision as well as taking an overview of the health and function of their eyes and how they work together The OCT scan takes just a few seconds and is non-contact and painless A customers OCT images will be stored on file so we can help note changes over time a real benefit to the monitoring of someones overall eye health OCT scans are additional to the normal eye test and can be requested when the appointment is booked or when the customer arrives in store The cost of this scan 10 is in addition to the eye test and not covered by the NHS examination
