What Is Lasik
In recent years more and more people are thinking about getting rid of their glasses or contacts, but most of them cringe at the thought of having surgery done on their otherwise healthy eyes. This article is for those of you that are thinking about having a LASIK surgery and finding it hard to find information on the subject. LASIK, with it’s time tested technology and precise surgical skill, is one of the safest, most effective eye surgery on the market.
LASIK is the use of a leaser beam to modify and reshape the cornea of you eye, thus improving your vision. But why do you have bad vision in the first place?
Our vision is dependent on one thing, light. Without it our vision will not work at all. Our eyes are built such as that they take the light in our environment, or light rays, on the front of the eyes and refract (bend them) so that they become focused on the inside of the eyes surface (the retina). You can very much compare the procedure to that of an camera.
The light on the retina then produce an image that optic nerve then transfer to your brain. The brain interprets the signals and we view them as images. But why do some of us don’t see this image as others do?
The problem lies in that the cornea might be deformed. This means that the light rays being transported to your retinas become corrupted, and the image become malformed. For those of you that experience this problem, LASIK eye surgery might be just the solution.
LASIK stand for Laser-Assisted-In Situ-Keratomileusis and is a surgery method which uses laser to correct vision problems for people that are shortsighted, longsighted and anyone with astigmatism.
Before the use of the Excimer laser mechanical tool is used to create a “flap” of the outer corneal tissue that can be folded out of the way and then be put back in place after the surgery. This flap is created to be able to access the underlying corneal tissue that is to be reshaped.
LASIK and most other laser eye surgery work by focusing a tight beam of light, a laser beam onto the surface, the cornea of the eye. Upon contact with the cornea the laser will then, vaporize a very, very small portion of the surface. With the aid if sophisticated equipment the doctor are able to adjust just how much that will be vaporized according to your vision problem.
Once the laser has finished and the flap has been replaced it start to naturally seal itself to the rest of cornea. You will have to wait a few days for your eyes to heal and accommodate, but once that is done, you will no longer need glasses nor contacts. Compared to other eye surgery the healing time is quite quick and one of it’s main advantages.

The Importance of Regular Eye Tests
It is recommended in the UK that people with eye or vision problems should have an eye test every two years. There are a variety of reasons behind this, and it is very important that you do get regular eye tests because they could save you a lot of trouble in later years.
Primarily, eye tests serve as a check up to ensure that your vision correction prescription – ie, your glasses and/or contact lenses – is up to date. Without the right prescription, not only can your sight suffer but the condition of your eyes can decline overall. This means that bigger problems could occur in the future that can be rectified in advance simply by having an eye test.
Eye tests also serve as a way for optometrists to monitor any early signs of eye disease. As with many health problems, the sooner a problem is identified, the sooner it can be treated – with a higher likelihood for success than if the problem is allowed to persist. Problems like glaucoma and cataracts can be identified far earlier than they might be if left alone, and dealt with in a comparatively painfree fashion.
At an eye test, your optometrist will undertake several measures to determine the health of your eyes and the quality of your vision. These include a discussion of your health and lifestyle background, followed by tests such as the measurement of your spectacle power, the measurement of your eye pressure – key to discovering glaucoma – autorefraction to help with your base prescription and a test of your visual acuity. This test determines how well your vision works based on near and far distances, usually involving the reading of letters on an eye chart.
There are other tests your optometrist in order to determine any other problems you may have, which check the general health of your eyes, including the strength and flexibility of the muscles in the area.
By booking regular eye tests, it is far more likely that you will save yourself from future pain and discomfort due to the greater chance of identifying any problems before they become too difficult, as well as ensuring your prescription is completely up to date so you are not at risk of entailing any other damage.
Your optometrist will also be better informed to suggest a course of treatment, whether it is new glasses or LASIK laser eye surgery for corrective purposes – making regular eye tests an essential part of your routine health checks.

Enjoying an Active Life with Improved Vision
Many people with good vision don’t realise how lucky they are in being able to be as active as they feel like without their eyesight hampering their lives. For some people, unfortunately, poor eyesight can get in the way of leading an active life, which can be a cruel occurrence for sporting fans or parents with active children.
Kids love to run around and play, and parents should be able to take part in this. Playing with your children and taking an active interest in their games and activities is an important bonding tool that helps to seal your relationship for years to come. The more you bond with your child, the closer you become – which is why having the physical ability to take part in their games is so important. If your vision is holding you back from this, then you could be missing out on a crucial part of life that your children will grow up remembering.
Whether it’s taking part in outdoor games or even simple, relaxed activities like reading or helping them with their homework, bad eyesight can hinder many people to the extent that they simply cannot undertake these things and both parent and child experiences a loss.
On the sporting field, bad eyesight can mean poor judgement of distance and speed, and poor depth perception could lead to dangerous outcomes. What’s more, even if these aspects of your vision are okay, insufficient quality of vision could mean that games like cricket and tennis are off the cards because you simply cannot make out where the ball is – a disappointing result for enthusiasts of the game.
So what can you do to correct these problems and lead a happy, more active life without being hindered by your vision? In terms of enabling you to run around more, glasses don’t tend to be the best option, and many people tire of using contact lenses daily – when the most desired solution would just be to have good eyes in the first place.
That’s why it might be worth looking into laser eye surgery. Although many people may see this option as an expensive one, the results will instantly prove that the treatment is worth every penny, especially when the costs of glasses and contact lenses are considered. Following just one safe, speedy procedure, patients can find their vision improving significantly – meaning a whole new world of activity suddenly becomes open to them.
Whether sports mean a great deal to you or you want to be able to bond with your kids over the things that matter most to them, laser eye surgery could really offer you the freedom you’re searching for.
