How eyes work

The eye functions on a similar principle to an old fashioned camera. Your iris or coloured portion of your eye acts as the shutter regulating the amount of light. The cornea or clear dome covering your iris, combined with your lens behind the iris are the lenses that focus the light onto your retina at the back of your eye. This simulates the film of a camera sending images to the brain.

The shape of your eye determines how well your vision can focus. Light rays enter the eye through the clear cornea, then through the pupil and the lens.

In a normal eye the light rays are focused onto the retina, a light-sensitive tissue lining the back of the eye. Signals from the retina are sent through the optic nerve to the brain, where they are interpreted as the images we see.

Refractive errors & surgery procedures


Refractive errors

Refractive surgery procedures attempt to fix this by changing the shape of the front surface (the cornea) or adding a permanent lens to improve the focus.

View Eye Treatment Options

Eye conditions treatable by refractive surgery include:


Also known as short-sightedness, myopia is the most common refractive error of the eye in which objects in the distance appear blurry and objects close up are seen clearly. An example of someone suffering with myopia would be the inability to read road signs until they are almost driving past them.

Hyperopia, more commonly referred to as long-sightedness, is a refractive error where distant objects are seen clearly while close up objects appear blurry.

Astigmatism is a common eye condition where both close and distant objects appear blurry. This is due to the irregular shape of the cornea or the curvature of the lens inside the eye.

Presbyopia is the loss of the eye's ability to focus on nearby objects, as a result of the natural ageing process of the eye.

A cataract is a loss of clarity within the lens of the eye. A normal lens is clear and allows light to pass to the back of the eye. When a cataract forms, the lens becomes stiff and cloudy, which blocks the passage of light to the retina.

Frequently asked questions

Am I eligible for Lasik for CustomEyes?

Generally, a suitable candidate will be at least 20 years of age, have had a stable vision for the last 12 months, is not pregnant, is free of certain diseases of the cornea and retina and is generally in good health.

How long will the procedure take?

Each procedure takes only a few minutes on each eye but you will need to be at the centre for a few hours to ensure all pre- and post-operative checks are carried out.

How soon can I get back to normal, drive, play sport or go to work?

Most people return to work and drive the day after LASIK surgery.

Will I be able to throw away my glasses after LASIK?

This depends on your age and what you and the surgeon decide. The goal is for you to throw away your glasses!

Do I need to take time off from work?

This depends on the procedure you have and your work environment. It is possible to have a consultation and surgery on the same day.
