Laser treatment of farsightedness
The possibility of laser eyes to correct farsightedness is limited to a certain diopter value. Up to +4 diopters, very good results can be achieved with LASIK treatment. In addition, laser eye correction is possible, but afterwards it is usually not possible to completely do without a visual aid despite surgery.
Depending on the individual case and individual visual impairment, there are also other applications that are carried out with laser and discussed in a preliminary examination for applicability in the individual case. In general, it can be said that farsightedness can be treated effectively and sustainably through laser surgery. You can often do without glasses or contact lenses afterwards.

The LASIK procedure is most often used to correct Farsightedness used. To careful preliminary examination and preparation for surgery local anesthetic eye drops and in some cases too Sedatives The eye surgeon removes only a small amount of tissue in the middle of the eye and instead in the Periphery (on the edge of the Cornea) a little more, so a physical one Converging lens is modeled into the cornea.
This is how the too flat curvature of the cornea balanced by lasers and a sharp image on the Retina pictured. This lasering allows even with thin corneas make an intervention because little tissue in the middle must be removed. The engagement is almost completely painless and takes about ten minutes per eye.
The costs are around 2000 euros per eye, which, however, are not borne by the statutory health insurance and thus by the patient after a decision by the Federal Social Court to pay yourself are.
There is a risk of under- or over-correction, which can, however, be remedied by making improvements. Dry eyes can occur, but it resolves itself after a few weeks. In order to Infections be prevented, get patients right after the operation regularly antibiotic and anti-inflammatory eye dropuntil the eye is completely healed.
Lasers for presbyopia
Is new Laser process, which can also be used for presbyopia and such Reading glasses as an aid makes redundant.
Requirements for treatment are one sufficiently thick cornea and healthy eyes without gray or glaucoma. The effect is optimal in patients with low farsightedness from +0.5 to +1.0 diopters.
Often just that not dominant eye treated (similar to how the left hand is not dominant in right-handed people and is so less used in everyday life). Because that operated eye becomes minimally myopic (up to approx. -0.5 diopters), so that the reading ability improves, but the Distance vision deteriorates becomes. This effect can be achieved in advance contact lenses can be simulated to show the patient how brain balance the effect and all optimal vision after the operation can guarantee.
The eye is only with eye drop stunned. So that the eye remains calm and relaxed during the laser treatment not moved, a ring is put on and the eye is stabilized with a slight negative pressure. The laser operation then lasts not even a minute.
Within the Cornea the laser creates several concentric rings, these are centered over the pupil. Through these fine rings, a laser forms in the middle of the cornea and thus in front of the pupil tiny protrusion of the cornea.
Externally, there is no injury from the laser, as this is its concentrated power in the depth of the cornea unfolds and the treatment thus only within this takes place. Infection is practically impossible, so that the Minimal complications of the operation are.
A typical, but slight, side effect of laser treatment for farsightedness is vision weak concentric rings of light around light sources at night or at dusk. These rings correspond to the laser rings in the Cornea and in most cases grow together over time less weeks to monthsso that the perception of the rings also disappears.
Serious side effects like Deterioration in visual acuity are not knownHowever, there are still no long-term results from lasers in farsightedness, as the procedure has only been used for 2 years. It is therefore not clear whether the effect is actually lasting or one repeated treatment necessary can be.
The Cost of around 2500 euros the statutory health insurances do not take over.
