Nearly everyone (98%) is now suitable for laser eye surgery. Ideal candidates are in good general health and specifically have healthy eyes (apart from having a refractive error).
There is plenty of misinformation out there, and laser eye surgery is no exception. Here are the top 5 things that many people don’t know about laser eye surgery:
- Laser eye surgery can treat astigmatism
- Laser eye surgery can treat very high prescriptions
- Laser eye surgery can treat ageing eyes
- Laser eye surgery is relatively painless
- Laser eye surgery is permanent
Laser eye surgery requirements
There are some laser eye surgery requirements that might make laser eye surgery unsuitable for you. If you have specific questions about suitability, we can share general laser eye surgery requirements with you over the phone. For a more specific recommendation, we can examine your eyes and give you a medical recommendation at your first visit.
You don’t need to understand how laser eye surgery works to benefit from it. However, many people are fascinated by a technology that sometimes feels like magic.
First of all, it’s important to think about the eye as a camera. When light enters the eye, your front lens (your cornea) bends the light so that it focuses on your retina. The light travels through an internal lens and then onto the retina. The retina (the film at the back of the eye) then interprets the light as an image and sends the signal to your brain so that you can see.
Just like some people are tall or short, some people have longer eyes and some people have shorter eyes. While many people’s eyes are round, some are more oblong, like a rugby ball. In normal eyes, the light passes through the cornea to a point on the retina.
In a Short-sighted, Long-sighted or astigmatic eye, the cornea bends the light and it incorrectly meets your retina so that the image you see is blurry and/or distorted.
In a nutshell, a laser eye surgery can fix this blurriness and distortion by applying a laser to the surface of your eye (the cornea) to change its shape and alter the curvature that causes the incorrect bending of light.
As a result, the reshaped cornea can then bend the light in such a way that it meets the retina in a correct way, which enables you to see as if your eye was a normal shape and length.
The main alternative to laser eye surgery is spectacles and contact lenses.
Is laser eye surgery better than spectacles?
Many patients agree that being spectacle-free
- Enhances their lifestyle
- Improves their appearance
- Increases their convenience
- Costs less than long-term spectacle use
- Increases their personal safety
- Improves their performance in sports and at work
Is laser eye surgery better than contact lenses?
Some patients choose to wear contact lenses as an alternative to spectacles. Many of these patients agree that being contact-lens free
- Increases their lifestyle flexibility
- Saves time and ongoing costs
- Reduces the incidence of sight-threatening contact lens infections
- Eliminates discomfort associated with contact lenses
