silmänmuovausleikkaus

Silmänmuovausleikkaus, also known as refractive surgery, encompasses a group of surgical procedures that aim to correct or improve vision problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These conditions occur when the eye's shape prevents light from focusing properly on the retina, the light-sensitive tissue at the back of the eye. By reshaping the cornea, the transparent outer layer of the eye, refractive surgery can alter how light enters the eye, leading to sharper vision.

The most common type of silmänmuovausleikkaus is laser-assisted in situ keratomileusis (LASIK). In LASIK, a thin flap is created on the cornea, and then an excimer laser is used to precisely remove corneal tissue underneath. The flap is then repositioned. Another laser-based procedure is photorefractive keratectomy (PRK), where the surface layer of the cornea is removed before laser treatment, and the corneal epithelium heals naturally. For individuals not suitable for laser procedures, other options like lens implants or corneal inlays may be considered.

The goal of silmänmuovausleikkaus is to reduce or eliminate the need for corrective lenses such as glasses or contact lenses. Patient selection is crucial, and a thorough eye examination is performed beforehand to determine suitability and discuss potential outcomes and risks. While generally safe and effective, like any surgical procedure, silmänmuovausleikkaus carries potential risks and side effects, which are discussed with the patient by the ophthalmologist. Recovery times and specific results can vary depending on the individual and the type of procedure performed.
