Common Conditions That Make You a Perfect Candidate for LASIK Eye Surgery

LASIK (laser assisted in-situ keratomileusis) eye surgery can significantly improve eyesight and reduce vision problems caused by common eye conditions. LASIK eye surgery works by reshaping the cornea, allowing light to travel effectively to the back of the eye. Surgery can be performed on an outpatient basis, using eye drops to anaesthetise the eye. While the procedure is not suitable for everyone, there are 3 conditions that respond well to LASIK eye surgery.

LASIK eye surgery

Astigmatism

Astigmatism is an eye condition that causes blurred vision and visual distortions. While some sufferers are born with the condition, it can also be caused by an injury or trauma to the eye. Astigmatism is a result of problems with the shape of the cornea or lens. The cornea is a layer of tissue that sits at the front of the eye and is usually shaped into a curve. Irregularities in the shape of the cornea lead to blurred vision, eye strain and headaches. Focusing on an object for a prolonged period, such as when reading, writing or looking at a computer screen, can also cause physical tiredness for some astigmatism sufferers. LASIK eye surgery has produced high levels of success in treating astigmatism. For those with severe astigmatism, additional treatments may be required.

Short-Sightedness

Short-sightedness, also known as myopia, is a common problem that causes blurred vision. Close objects may look sharp and clear, while objects in the distance appear blurred and dull. Short-sightedness can be caused by a variety of factors, including environmental and genetic factors. Up to a third of the population is thought to suffer some degree of myopia, from mild inability to focus on distance objects, to severe sight restriction requiring special glasses or contact lenses. Severe myopia can also increase the risk of developing glaucoma, cataracts, detached retina and macular degeneration. LASIK eye surgery can bring significant improvements to distance vision, although severe cases of myopia may require more than one treatment.

Far-Sightedness

Far-sightedness, also known as hyperopia or long-sightedness, is an eye condition that makes it difficult for sufferers to focus on close objects. People with hyperopia can often see distant objects clearly, but focusing on closer objects causes eye strain and tiredness. Far-sightedness may be the result of an irregular-shaped cornea, a thin lens or problems with the length of the eyeball. Over a long period of time, hyperopia can lead to a squint or cause one eye to become more dominant than the other, known as a lazy eye. The cause of far-sightedness will need to be determined before considering LASIK eye surgery, as underlying medical conditions may need to be addressed first. Age, hereditary factors and diabetes are all possible causes of hyperopia.

LASIK eye surgery is a quick and painless procedure that has high levels of success in treating astigmatism, short-sightedness and far-sightedness. Once surgery has been completed, eye drops should be used to help prevent infection. Many people notice improvements in their vision straight away, but it can take a couple of weeks to achieve maximum benefits.
