Eye Conditions That Are Treatable Using Lasik Eye Surgery
Eye Conditions and Treatments Explained
In this article, we want to tell you a little bit about the different eye conditions that can be treated with LASIK surgery. The vast majority of people suffer from one of four eye conditions. They are:
Farsightedness or long-sightedness – Hyperopia
Shortsightedness or nearsightedness – Myopia
Blurred vision – astigmatism
Presbyopia – a form of long-sightedness
Laser eye surgery can be used to treat all four of these common eyesight problems.
Lasik for Farsightedness
Farsightedness is very common. It is an eye condition that normally develops once someone reaches their late thirties or early forties.
The Symptoms of Farsightedness
People with far or long sightedness can see things at a distance without a problem. However, when they read or do some other kind of close work everything appears blurred.
If the text is big enough it may be possible to continue to read without glasses or contacts. However, something like newsprint becomes impossible to read. Because of the way the body tries to adapt, distance vision can begin to suffer too.
Many people with farsightedness also get headaches. Some suffer from eyestrain and may get weepy eyes if they read or do close up work for too long.
Get Help with Farsightedness Early
Normally, the eye deteriorates because of genetics. Long sightedness tends to run in families. However, occasionally a tumour causes the symptoms. This fact combined with the fact that leaving your farsightedness untreated can eventually cause other vision problems means that you should go to your optician as soon as symptoms develop.
What is happening to the Eye?
As we age the shape of our eyes change. Light no longer reflects off or enters the eye in the right way. In people with farsightedness, the eye is shorter than it should be or the lens is set too far back in the eye.
Sometimes the problem is caused by Presbyopia. With this condition, it is the elasticity of the eye that is the issue. The eye is no longer agile enough to respond and focus properly on near objects. In the early stages, concentrating can help because the eye will eventually respond and make the necessary adjustment. However, as the condition worsens the eye is no longer flexible enough to respond, as it needs to.
Laser eye surgery for long-sighted people has been carried out for several decades now. Glasses and contacts can be worn, but most people prefer the permanent solution that laser or LASIK surgery offers.
When the long-sightedness is caused by a lack of flexibility in the eye a special form of surgery called monovision LASIK is carried out. When someone has presbyopia, the surgery may not be able to correct their vision to the extent where reading glasses will no longer be needed. Sometimes it is possible, sometimes it is not.
This is something that not everyone understands. Therefore, the reviews for monovision Lasik are mixed. Some patients do not realise that they may still have to wear reading glasses. When they find out that they are one of the ones that does still need glasses to read they are naturally disappointed and this is reflected in what they say in their LASIK review.
Like farsightedness, myopia or shortsightedness is caused by the eye not being the right shape. It is the most common eyesight problem.
Once again, the aging process causes the eye to change shape. The problem is that the eye is too long, or the cornea is too curved. As a result, light does not enter the eye in the right way; the image is focused in the wrong part of the eye, and is therefore blurred.
The Symptoms of Nearsightedness
Nearsightedness rarely causes eyestrain. However, things in the distance look blurred. This makes tasks like driving or playing certain sports difficult, even dangerous.
Myopia correction is quick and simple when laser surgery is used. The longest part of the process is the doctor assessing you and making sure that they are a suitable candidate for eye surgery. The actual LASIK surgery only takes ten or fifteen minutes.
It is also possible to treat the condition with Photorefractive keratectomy, which is also called PRK. In this surgery, a thin layer of corneal tissue is removed to flatten the eye.
Astigmatism is a condition in which the eye is not completely round. To work properly, the eye has to be a sphere. This ensures that when light enters the eye it refracts evenly. When the eye changes shape, the light is no longer evenly distributed and the image is blurred.
How the shape of the eye changes varies from person to person. For virtually all cases of astigmatism, surgery is a good solution. It corrects the shape of the eye allowing it to function correctly once again.
Laser eye surgery for astigmatism does not take long. The actually surgery can normally be carried out in around fifteen minutes. However, the evaluation and follow up checkups take between 30 and 45 minutes each.
There are several types of laser surgery for astigmatism. All of them work, but the most popular form is Lasik eye surgery for astigmatism. Given the fact that as people age the way the shape of their eye changes varies a tailored approach to eye surgery for astigmatism has to be taken.
