One of the most important factors for choosing the right procedure for you is your eye condition. Identify your visual problem below, and see which of our procedures might be right for you.
NORMAL VISION (EMMETROPIA)
The state where an eye is clearly focussed for distance vision without glasses or contact lenses is called emmetropia. Emmetropia is achieved when the eye is relaxed and the optical power and the length of the eye are in balance resulting in images that are perfectly focussed on the retina.
Short-sightedness occurs when the eyeball is too long relative to its focussing power or if the focussing elements (i.e. cornea and/or lens) are optically too powerful for the length of the eye. Often short-sightedness results from a combination of these factors making distance objects appear blurry.
Long-sightedness occurs when the eyeball is shorter than normal or the focussing elements are optically too weak for the length of the eye. Long-sighted people often have difficulty focussing on objects up close (e.g. reading, computers) but see distance objects more clearly. However, for those with large amounts of long-sightedness the distance vision can be blurry too.
Sometimes people confuse long-sightedness with presbyopia, which also causes near vision problems, but for different reasons.
Astigmatism occurs when light focusses unevenly due to the shape of the optical elements of the eye. While an eye without astigmatism would be shaped like a sphere (e.g. a round ball- soccer or basketball) an eye with astigmatism is shaped more like an Australian rules or rugby ball. This means that the light bends more in one direction than another, causing blurry or distorted vision over all distances. Most of us have some astigmatism and it also occurs with short or long-sightedness.
Presbyopia is a natural part of the ageing process and makes reading small print more difficult, usually in those over 45 years of age.
Presbyopia occurs because the lens in the eye, which controls our near focus, becomes harder and less able to change shape. As such, in presbyopia the lens cannot alter the focus of the eye from distance to close objects (e.g. reading, computer). People with presbyopia often require reading or multifocal glasses.
TREATMENT FOR PRESBYOPIA
Keratoconus is a degenerative condition of the eye that involves thinning of the cornea (the transparent, front surface of the eye). As a result of the thinning the normal shape of the cornea becomes distorted and a cone-shaped bulge develops; resulting in a progressive blurring of the vision. People who suffer from keratoconus may wear glasses or, more often, hard/rigid contact lenses are used to treat their blurry vision.
A cataract is a cloudiness that develops in the lens inside of the eye as we age. This debilitating cloudiness prevents light from reaching the retina resulting in distorted or blurry vision.
TREATMENT FOR CATARACT
Please note that the procedure options listed above are a guide only. At your consultation, we will perform a comprehensive range of tests to evaluate the structure and health of your eyes. The procedure/s recommended to you will depend on your individual suitability and lifestyle, and this will be discussed with you at your consultation.
