“Hundreds of thousands of Australians have undergone laser eye surgery and, as reported in an article by Choice Magazine, the vast majority were very happy with the result and would recommend or repeat it. “

Today, there are three types of laser vision correction that are performed to correct a refractive error –
While a variety of names have been used to market them, these names mainly refer to the specific manufacturer of technology that a clinic chooses to use.
If you are considering a vision correction procedure, the first step is to book a consultation in order to find out whether or not you are suitable for laser eye surgery.
If you are between the ages of 18 and 45 and have had a stable prescription for two years, you will most likely be suitable.
During your initial assessment, you will undergo a comprehensive range of eye examinations. This will include assessing the thickness of your cornea, your current prescription and the general health of your eye.
Your laser eye surgeon will then tell you which of these three procedures will best suit the anatomy of your eye. Around 90% of people will be suited to LASIK.
If your cornea is deemed too thin for LASIK because of the need for a flap, you may be recommended ASLA.
If you have a particularly high prescription, laser vision correction may not be recommended to achieve the visual outcome that you require. The likelihood is the surgeon will suggest another form of vision correction surgery such as an implantable contact lens (also called a phakic IOL or an implantable collamer lens).

A person with 20/20 vision is lucky enough to have a cornea that is perfectly shaped to focus the image onto the back of the eye.
People who suffer from short-sightedness, long-sightedness and astigmatism have a cornea that is not perfectly shaped – it is either too steep, too flat or too oval to focus the light on the back of the eye. This results in a blurred image and vision problems.
Although there are three basic forms of laser vision correction procedures, ultimately they all achieve the same result – a laser is used to reshape the cornea, creating the best curvature in order to focus light on the back of the eye.
There are many reasons people seek to correct their vision.
These are all valid reasons that people turn to laser vision correction.
