The Sight Test
Regular eye examinations are extremely important for a number of reasons. This section outlines what's involved and why they are so important.
What should I expect during my eye examination?
Refraction I usually check the vision first and work out your refraction and discuss with you whether new spectacles are required. I use a trial frame and lenses as this simulates everyday life better, in particular it makes it easier to judge reading and computer distances. I will discuss with you whether you would benefit from new spectacles and show you what difference a new prescription would make. The decision as to whether you purchase new spectacles is yours.
Internal and External Examination of your Eyes
To make sure your eyes are healthy I will always examine the front and back of your eyes using a slit lamp with a wolk lens. I now have an OCT (Optical Coherence Tomography) which takes 3-dimensional MRI type images of your retina. You can see the layers of your retina at a cellular level. This is useful in finding defects in the macula area which sometimes need treating. It also measures the thickness of the nerve layer round the optic disc, making it an early predictor of glaucoma. I do charge an additional £30 for using the OCT.
Intra-Ocular Pressures and Visual Fields
I use the latest equipment for visual fields and measuring your intra-ocular pressures. These tests are done on everyone over 40. Along with examination of your eyes they are important in glaucoma diagnosis.
Binocular Vision Tests
It is really important to check that small children have good binocular vision. If a squint is not picked up early the vision in the squinting eye can be permanently reduced. After 8 years old little improvement can be made so early diagnosis and treatment is vital. Older people have binocular vision problems sometimes and this can lead to double vision and uncomfortable vision. This can usually be corrected by prisms in spectacles but investigation is necessary into the cause.
One of the major new developments in Optometry that has recently been be introduced is a change in the law that allows Optometrists who have the appropriate qualifications to prescribe medications for non-sight threatening eye conditions. I have now completed the necessary courses, passed the exams am able to prescribe ophthalmic drugs.
Many people have eyes that water excessively, especially on windy days. This can be due to excess tears being produced or poor drainage into the lacrimal duct. Alvin has introduced a lacrimal service whereby we analyse the cause of the tearing problem and where appropriate, syringe saline through the tear ducts. This can resolve mild problems and is also diagnostic as to whether further treatment would be beneficial.
