How does Laser Eye Surgery correct my vision?

12 Jan 2014

It’s understandable that you might be cautious when it comes to using a laser to correct your eyesight, but the simple truth is that Laser Eye Surgery has been in existence in some shape of form since the 1980s.

Laser Eye Surgery technology has seen some massive advances in recent years which has resulted in greater accuracy using a minimally invasive technique.

Optilase Laser Eye Clinics provide the most advanced laser technology to people all over the country, and offer a through consultation process.

Will my entire eye receive laser treatment?

No. The entire Laser Eye Surgery procedure is computer-controlled and only corrects the shape of your cornea at the front of the eye.

And if you were worried about a red-hot laser beam being pointed at your eye, then you’re in for a big relief - the type of laser used during Laser Eye Surgery is known as an Excimer Laser which emits a cool ultraviolet light.

The Excimer Laser has been designed to deliver precise pulses of cool laser light to a specified area and will not enter the back of the eye.

Why is the cornea the target during Laser Eye Surgery?

The human eye needs to bend light that enters through it in order to see objects clearly. This process known as refraction takes place in the cornea and the lens.

Because the cornea is responsible for over 60% of refractive power and refractive errors are typically caused by a misshapen cornea, this is why it is the focal point for Laser Eye Surgery.

What happens to the cornea during Laser Eye Surgery?

Regardless of whether you are shortsighted, longsighted or suffer from astigmatism, the single common thread in each condition is that you have an irregular shaped cornea that prevents you from seeing clearly without the aid of corrective lenses.

During Laser Eye Surgery, tiny amounts of tissue are removed from the cornea using the Excimer Laser. The use of numbing eye drops prior to surgery mean that you will not feel any pain during the procedure.

This creates a cornea that will then be able to bend light correctly, allowing it to focus accurately on the back on the eye, thus creating instant perfect vision.
