Simplifying ophthalmology with descriptions relating to the most well known eye afflictions

Ophthalmology is more than a specialist subject, just because most people know hardly anything about the best practices for ensuring their eyes stay healthy and how to spot when they need to visit an ophthalmologist. Ophthalmology is a particularly tricky topic because the vast majority are very protective of their eyes and even dislike the idea of touching them when inserting contact lenses. So to give you a deeper insight into ophthalmology the eye specialists at eyesite.org have drawn up a short article to help you identify how your eyes function and the key symptoms associated with common eye conditions:

The technology utilised by ophthalmologists changes depending on the eye condition being treated. In the instance of invasive cornea surgery a Ziemer LDV Femtosecond precision laser will be used. This particular piece of equipment lets a surgeon operate effectively without the use of a blade. There is an OCT (Ocular Coherence Tomographer), which is a new form of non-invasive imaging technology for mapping the shape, size and contours of an eye. for those that suffer from more complicated conditions there is Anti-VEGF drugs and Fluorescein angiography treatments. These are just a few examples of the equipment and procedures that are being used currently by professional ophthalmologists.

Patients require a cornea transplant or graft when their cornea becomes permanently possibly through disease or external damage. For instance, if a person develops fuchs dystrophy (a corneal diseases which affects patients who are aged 50+) or Keratoconus (a disease which causes the cornea to thin and change shape) then a cornea transplant is usually required. During this simple operation healthy corneal tissue is grafted on to the diseased part of the cornea to restore the damage caused by the disease - the graft coming from the cornea of a deceased donor. cornea transplants or keratoconus surgery are the most severe treatment methods as in some cases these conditions can be managed with corrective lenses.

In the United Kingdom of Great Britain and Northern Ireland, universities can confer ophthalmology degrees. Good examples of the educational institutions include The Royal College of Ophthalmologists, the Royal College of Glasgow and, the Royal College of Edinburgh. A qualification must be held by an ophthalmologist in order to pursue that line of work in Great Britain. Once these qualifications have been achieved most individuals often gain placements at the NHS in order to further their practical skills and gain essential knowledge. As a matter of fact, a large number of laser eye specialists provide training programs to help people become entirely qualified ophthalmologists. However, most of the time these are vocational courses which can only be taken after a postgraduate qualification.

Lasik eye surgery, a form of refractive surgery, is used for correcting myopia, hyperopia and astigmatism. As a result, this surgery is a viable alternative to wearing corrective lenses or glasses, which the majority of people don't enjoy wearing. The procedure is similar in certain aspects to other surgical corrective options like photo-refractive keratectomy and refractive surgery, making it a common answer to solving bad eye sight. As a procedure, it involves surgical remodelling of the cornea, specifically reshaping its curvature. There is a small probability that the eye will reject the surgery and progressively revert back to its old condition but other side effects are minimal.

Macular degeneration is a painless condition which leads to a gradual loss of vision in the macula/centre of the visual field caused by retina damage. When it develops it can cause impaired visions, specifically when reading or when trying to recognise faces. There are two main types of the progressive disease; dry and wet. The first is caused when the cells in the macula degenerate and accumulate behind the retina. Alternatively, wet macular degeneration is classed as the more serious of the two and is caused when blood vessels grow abnormally in the choriocapillaris behind the retina. As the effects of macular degeneration can usually be halted by taking vitamins or mineral supplements surgery of eye is not always the most appropriate treatment method.

Even though you may believe that cataracts only affects older people, younger people can be affected by the condition too. They are better known as congenital cataracts and they develop just before or just after birth. The condition is characterised by the clouding of the eye and can sometimes lead to complete opacity. Symptoms include near-sightedness (myopia) due to increased focus of the lens, the slow yellowing of the lens and difficulty in seeing the colour blue. A cataract operation or cataract surgery are two treatment options. If treatment is not provided loss of vision and even blindness can result. In the elderly the condition leads to shrinkage of the lens and swelling.
