Long-sightedness - Hyperopia
Farsightedness is the visual disorder characterised by blurred near vision. Farsightedness, usually a congenital defect, is caused by a shortening of the eye.
Improvement of long-sightedness, incl. regular eye checks
Farsightedness, usually a congenital defect, is caused by a shortening of the eye. People who are farsighted can usually still see well in the distance, while objects in the near distance appear blurred. The opposite is true for short-sighted people: objects near appear sharp and those far away appear blurred.
Normal farsightedness can be caused by two different things: Axial hyperopia or refractive hyperopia. If the eyeball is actually shortened, this results in axial hyperopia, which restricts vision. If there is too little refractive power in the corneal vitreous body-eye lens system (optical apparatus), refractive hyperopia can occur. It is advisable for all sufferers to have their eyes checked regularly by an ophthalmologist.
Examples of farsightedness - hyperopia
Objects that are very close to each other are intended for persons with Long-sightedness (also called hyperopia, hyperopia or hypermetropia) only blurred.
Treatment options for farsightedness
Long-sightedness can be improved with different methods.
Spectacle lenses or contact lenses compensate for the defective vision.
In certain cases, farsightedness can even be cured with an operation. The aim is to enable the patient to see clearly without glasses.
If several methods are combined, farsightedness can often be treated well.
Operative correction of farsightedness
In the surgical therapy procedure, the cornea is permanently flattened with a laser.
The laser processes are called Photorefractive keratectomy PRK, LASIK or LASEK.
In the best case, the laser procedure can be used to cure myopia.
Long-sightedness can be corrected with the laser up to a strength of +4 diopters.
Laser procedures for short-sightedness and long-sightedness
There is an almost infinite range of eye laser procedures, which differ from each other to a greater or lesser extent. These can be divided into two main groups: the superficial and the deep procedures. The main difference is in the procedure and the target tissue layer. The most important and current procedures are the following:
