Therapy Long-sightedness
There are now several treatment options for the correction of farsightedness. The oldest solution is glasses. Later contact lenses were developed.
Basically, contact lenses are small elastic lenses that are placed on the cornea. The advantage is that you do not immediately see that you are wearing glasses (cosmetic effect) and when doing sports you do not need glasses that are bothersome and sometimes dangerous. The disadvantage is that both eyes and contact lenses need special care in order to maintain the functionality of the contact lenses and to avoid injuries to the cornea.
In principle, these are convex lenses (also called plus lenses or converging lenses), which support the refractive power of the eye. This means that the part of the refractive power that the eye lacks is replaced by the converging lens. Nowadays, technology has progressed so far that it has become very easy to calculate the refractive power of the eye.
However, it also requires sensitivity and experience to determine the power for the required lenses, since it is not possible to correct total farsightedness (due to accommodation spasm, see above), but the manifest part and the latent part as far as possible. In general it can therefore be said that the strongest convex lenses can be prescribed, where just the sharpness in the distance is best. In the meantime it is also possible to treat farsightedness with laser therapy.
In this case, the laser is used to process the cornea to such an extent that the refractive power ratio is back in balance with the axial ratio of the eyeball. This type of therapy is simple and successful in most cases. Nevertheless, there are various risks to be considered, such as corneal scars, over- and undercorrection and even deterioration of visual acuity.
Prognosis
Since farsightedness rarely increases on its own and can be easily treated with corrective lenses, the prognosis is quite good. Although presbyopia increases with age, it can be treated with the appropriate corrective lenses.
