Farsightedness - Hyperopia

Farsightedness is the vision disorder characterized by blurred near vision. Farsightedness, a mostly congenital defective vision, is caused by a shortening of the eye.

Improvement of farsightedness, including regular eye examinations

Farsightedness, a mostly congenital defect of vision, 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 nearsighted people: objects near appear sharp and those far away appear blurred.

Normal farsightedness can be caused by two different things: Axis hyperopia or refractive hyperopia. If there is an actual shortened eyeball, axial hyperopia occurs, which limits vision. If there is too little refractive power in the corneal vitreous body-eye lens system (optical apparatus), refractive hyperopia may occur. It is advisable for all sufferers to have their eyes checked regularly by an ophthalmologist.

Examples of farsightedness - hyperopia

Farsightedness Without impairment

Objects that are very close are difficult to see for people with farsightedness (also known as hyperopia or hypermetropia) can only be recognized in a blurred way.

Treatment options for farsightedness

Treatment options:

Farsightedness can be improved with various methods.

Eyeglass lenses or contact lenses compensate for the defective vision.

In certain cases, surgery can even cure farsightedness. The goal is for the patient to see sharply without glasses.

If several methods are combined, farsightedness can often be treated well.

Surgical correction of farsightedness

In the surgical therapy procedure, the cornea is permanently flattened with a laser.

The laser procedures are called Photorefractive keratectomy (PRK), LASIK or LASEK.

In the best case, the laser procedure can cure myopia.

Farsightedness can be corrected up to +4 diopters with the laser.

Laser procedures for myopia and hyperopia

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:

Femto-LASIK (Laser In Situ Keratomileusis)

Femto-LASIK is the most frequently performed laser treatment and life-style surgery with the highest human satisfaction. Under local anesthesia, the Femto-LASER is first used to prepare a thin flap (0.1 mm thick) on the surface of the cornea. This takes about 25 seconds. The eye is kept open with an eyelid retractor (you cannot close the eye).....

Trans-PRK (transepithelial photorefractive keratectomy)

In trans-PRK (also called SmartSight), under local anesthesia and after an eyelid retractor holds the eye open, the correction is performed on the surface of the cornea without contact or incision. During this process, the epithelium (the cells of the corneal surface that are constantly regenerating) are also automatically removed by the LASER. Previously, these were removed manually by the surgeon (PRK method). Am...

Artificial lens implants: Correction of higher refractive errors

Apart from LASER treatments, correction of refractive errors is also possible very precisely with the implantation of phakic lenses in the eye, in addition to the patient's own lens (phakic lenses). These treatments have been carried out for 30 years and have been performed several million times. The worldwide trend of implamtation is constantly increasing. Indications:- More severe refractive errors- Also for small corrections when...
