Crystalline Lens Imaging
Crystalline lens imaging involves the use of a special camera built into the optometrists’ slit-lamp microscope allowing detailed, high resolution videos and photographs of the crystalline lens (the lens inside the eye) to be collected. This is useful in monitoring and diagnosing cataracts. Crystalline lens imaging is a quick and painless procedure. It involves the optometrist inspecting your eye with a microscope which produces a beam of bright light. The process of image taking involves no flash unlike conventional cameras.
Cataract is an extremely common condition, affecting most commonly the over 60 population as result of the normal ageing process of the eye. Cataracts can be congenital (from birth) or acquired as a result of trauma to the eye (traumatic cataract), systemic health issues such as diabetes or associated with long-term use of specific drugs such as steroids (secondary cataract). There are many forms of cataracts, but they all involve changes to normally transparent crystalline lens, varying in degree from slight clouding of the lens to complete opacity. As cataracts become more opaque visual symptoms such as reduced clarity of vision, reduced contrast sensitivity, decreased colour sensitivity and increased glare become more prominent. Most cataracts progress slowly over a number of years and affect both eyes; potentially at different rates. Modern surgical techniques mean cataracts can be very effectively treated in the vast majority of individuals as a day case under a local anesthetic.Back Next
