What’s involved in vision correction?
More than half the world’s population need glasses or contact lenses in order to see well. It’s not surprising that more and more people are looking at corrective laser eye surgery to give themselves freedom from glasses or contact lenses.
Space Healthcare offer all the latest options for your vision correction. The best choice for you depends on numerous factors including your age, your current prescription and the condition of your eyes.
The expectations you have for your vision, your occupation and other lifestyle factors are also extremely important. All these pieces of information will help your surgeon advise on options that will be the best for you and your lifestyle.
Laser vision correction is a wonderfully effective approach to correcting vision by precisely reshaping the cornea at the front of the eye. Tiny pulses of laser light are used to recontour the cornea allowing your eyes to focus correctly and eliminate or reduce the need for glasses or contact lenses.
There are 2 main types of laser vision correction, LASIK and LASEK, and the only significant difference between the treatments is the way in which the eye is prepared for the treatment. The actual re-shaping process is exactly the same in both cases.
Laser vision correction could be the ideal solution for your myopia (short-sight), hyperopia (long-sight), astigmatism or reading vision
If a laser solution isn’t suitable, we can also correct your vision by implanting a lens, or replacing the lens
If you are short-sighted, long-sighted, or have astigmatism, light isn’t focused precisely on the back of your eye. Instead it falls either in front or behind the retina, creating a blurred image. Reshaping the cornea, at the front of your eye, allows the light to be focused correctly on the retina to give clear vision.
LASIK (Laser Assisted In Situ Keratomileusis) treatment involves recontouring the front surface of the cornea. It has 2 stages:
First, a very thin superficial layer or flap (the thickness of a human hair) is created using the Intralase laser and carefully lifted. All of our LASIK procedures are completely blade-free.
Secondly, the surface of the cornea is reshaped by the Technolas 217 cool laser. The corneal flap is then repositioned, and remains in place by natural suction. The flap remains joined to the cornea like a hinge, enabling it to be replaced in exactly the same position, allowing it to heal more quickly.
IntraLase LASIK takes just minutes to treat each eye and has a very quick recovery, with most patients returning to work inside 48 hours.
If you are short-sighted, long-sighted, or have astigmatism, light is not focused precisely at the back of your eye. Instead it falls either in front or behind the retina, creating a blurred image. Reshaping the cornea, at the front of your eye, allows the light to be focused correctly to give clear vision.
LASEK (Laser Assisted Sub-Epithelial Keratomileusis) may be the best treatment if you have thinner corneas or play a lot of contact sports.
steps in LASEK surgery are:
- Anaesthetic eye drops are applied to surface of your eye.
- A dilute alcohol solution is applied for the eye for about 30 seconds, and then is gently sponged off. The alcohol solution loosens and helps “float” the epithelium – the surface layer of the cornea.
- The epithelium is gently lifted from the eye and folded back.
- The surface of the cornea is reshaped by the Technolas excimer laser .
- The thin epithelial flap is put back in its original position. To keep the epithelium securely in place, a bandage contact lens is applied.
A few days later (after the epithelium has had a chance to securely reattach to the eye), the bandage contact lens is removed
