Short-sightednessExamination and treatment at DOmed
Short-sighted people see distant objects out of focus. This can lead to headaches, particularly after activities where it is necessary to concentrate on distant objects, such as driving.
How does short-sightedness occur?
Short-sightedness (myopia) is usually a consequence of either the eyeball being too long (axial myopia) or the refractive power of the lens, the intraocular fluid and the cornea being too high (refractive myopia). This means that the focus point is in front of the retina. The incident light is focused too tightly in relation to the length of the eyeball. The rays of light meet in front of the retina, so that a sharp image cannot be formed in the brain. Only light which reaches the eye from a short distance is able to be refracted correctly and correctly portrayed on the retina.
Special forms of short-sightedness
Simple myopia
This form of short-sightedness is hereditary and is also known as myopia simplex, benign myopia or “school myopia”. The latter refers to the age at which simple myopia emerges. This is usually between the ages of 10 and 12. After the age of 25, the visual impairment often does not increase further. However, in rare cases it continues to increase until the age of 30 and patients reach a prescription of -6 to -8 dioptres.
Malign myopia
This form of myopia, also known as myopia magna or myopia progressive, comprises an elongation of the eyeball, which takes place independently of external influences. The choroid and retina suffer as a result and become thinner, and the tissue begins to shrink. This results in internal bleeding and a pigmented scar in the area of the macula, which is also known as Fuchs spot and is a typical sign of this condition. In this form of short-sightedness, not only does the eyesight significantly decrease, but there is also an increased risk of the retina detaching.
Symptoms of short-sightedness
The symptoms of short-sightedness can include it being difficult to recognise projected slides, street names, individual papers or people in the distance. Additionally, the further away patients look, the blurrier objects appear. Affected patients often suffer from headaches after activities which require looking into the distance, such as driving.
How can short-sightedness be treated?
Short-sightedness can be corrected by glasses or contact lenses. This reduces the refractive power of the eye, moving the focus point backwards onto the retina. The refractive power of the glasses lenses or contact lenses is given with a minus sign (e.g. -2.5 dioptres).
As an alternative to glasses or contact lenses, the treatment of mild or medium short-sightedness with Femto LASIK is possible.
For severe cases of short-sightedness, good results can usually be achieved with lens implants.
In combination with presbyopia, short-sightedness can be corrected by placing multifocal intraocular lenses.
