Farsightedness is a bothersome eye defect that disturbs visual acuity, which quickly prompts you to seek ophthalmological advice. A way to permanently remove it may be laser vision correction. Unlike lenses and glasses, this refractive operation has a lasting effect. Only some laser treatments are intended for the correction of hyperopia.
Types of hyperopia
Farsightedness is also popularly called farsightedness and next to myopia, it is one of the most popular refractive eye defects. It is marked with a plus, and its main symptoms are lack of visual acuity, poor vision up close and sometimes also while looking into the distance, eye strain and headaches. Severe hyperopia in both eyes can result in amblyopia. Tests such as refractometry and skiascopy are used to detect hyperopia.
The specific types of hyperopia are:
- Latent hyperopia – may not be detected at a young age due to the good accommodation of the eye, which adapts better to observing objects that are close and far away. With age, the eye loses its optical power and then the problem of hyperopia may require correction.
- senile hyperopia is a fairly common problem that affects people over 70 and most often reaches 1,5 to 2,5 diopters; this type of hyperopia is not the same as presbyopia.
Laser correction of hyperopia – methods
Laser vision correction treatments allow for the treatment of problems caused by myopia, farsightedness and astigmatism. However, they are used for defects of varying severity, and in the case of hyperopia, some are not used – this applies to the ReLEx Flex and ReLEx Smile techniques. Quite limited possibilities laser correction of hyperopia they also apply to the EBK, PRK, LASEK and EPI-LASIK surface methods. They allow only a slight correction of this defect, but they are much more effective in the treatment of myopia and astigmatism.
The main method used in laser hyperopia correction is LASEK and FemtoLASIK or personalized iLASIK. In this way, defects are eliminated up to +4 or even +6 diopters. If your hyperopia is accompanied by aberrations, night vision problems and the halo effect, the Wavefront technique may be a good solution. The decision about the possible approach to laser vision surgery is made by the doctor on the basis of an interview and qualifying tests.

The course of laser correction of hyperopia
Laser hyperopia correction involves shaping the cornea with a laser beam in such a way as to emphasize it in the central part. The FemtoLASIK method with a femtosecond laser is most often used for this purpose. This relatively new procedure is safer than the standard LASIK procedure, accelerates healing and minimizes the chance of worse night vision or the halo effect.
FemtoLASIK laser treatment begins with local anesthesia. Then the deviation of the corneal flap is carried out. A laser acts on the exposed surface of the cornea, modeling it according to pre-programmed parameters. It takes at most several dozen seconds, depending on the severity of the defect. After the procedure is completed, the corneal flap goes back to its original place and the doctor protects the eyeball.

Recommendations after surgery and effects of correction of hyperopia
During the period convalescence after laser vision correction surgery the patient has recommendations that determine the speed of the eye healing process and the stabilization of vision. Rest after surgery is important, among others due to possible postoperative ailments, such as photophobia, discomfort or tearing.
Immediately after laser vision correction, it is recommended to sleep, stay at home, limit reading and staring at the monitor. Precautions include protecting your eyes from sunlight, rubbing, pressing, drying, and water (especially from bodies of water and swimming pools).

Correction of hyperopia and hyperopia with astigmatism is associated with a certain probability of incomplete treatment of the defect or its partial recurrence. In that case, if defect regression qualifies, after the time specified by the doctor, another treatment can be performed. Treatments correcting myopia are more effective, because they are associated with a lower percentage of recurrences of the defect.
