Only preventive effects possible
For short-sighted people, early reading of traffic signs, recognizing a friend on the other side of the street or finding the car in the overcrowded parking garage without visual aids is practically impossible. This ametropia, in which distant objects are imaged in front of the retina and therefore only blurred, affects almost every third German. A new study has now found that in children with myopia, advancing with eye drops can be partially stopped.
The study was able to show that the further increase in ametropia was less pronounced than in the control group in children with existing myopia due to the addition of eye drops with atropine AT over a year. "In the future, it could be a goal to prevent children with moderate myopia from getting high myopia," estimates ophthalmologist Dr. Robert Löblich of the Artemis Eye Clinic Frankfurt submitted the results. "But this does not make glasses unnecessary, the glasses may only become less thick." So with the eye drops an existing ametropia cannot be reduced.
In order to treat short-sightedness, visual aids must still ensure that the focal length of the eye is extended so that the light rays are focused on the point of sharpest vision in the retina even when the eyeball is longer. Normal glasses with so-called minus lenses are often sufficient. If you are bothered by the glasses or just don't get used to them, contact lenses offer an alternative. If you want to completely do without such visual aids, you can also have your ametropia corrected surgically with a LASIK procedure.
With LASIK, the refractive power of the cornea is treated using a cold light laser so that the focal point - like when wearing a visual aid - hits the retina again. LASIK is considered a very safe method to correct myopia down to minus eight diopters. The patient's cornea must not be too thin for laser eye correction to be possible. Laser treatment is generally not suitable for young people under the age of 18, as their eyes can still change. "With new developments such as Femto-LASIK, the process has become even more precise in recent years," explains Dr. Praiseworthy. "It also allows corrections for below average corneal thickness." After the operation, patients no longer need visual aids. But stronger short-sightedness down to minus 20 diopters can also be surgically corrected. Doctors use artificial lenses that are implanted in the eye in addition to their own lens. In a detailed discussion, the patient and doctor must clarify which method is best suited to the individual case and what are the advantages and disadvantages with extensive preliminary examinations.
