Refractive surgery refers to surgical ophthalmic procedures that modify the cornea to correct myopia, hyperopia, and astigmatism.
Depending on the characteristics and particularities of each patient, there are different techniques that can be used.
At Miranza Clínica Muiños, the Excimer laser is used, which is applied on the cornal surface or lifting a superficial layer of the cornea. It is totally painless, fast, safe and non-invasive.
Another technique used in patients with high diopters of myopia and farshigtednessis the implantation of a phakic intraocular lens. Finally, there are ICL lenses that are placed between the iris and the natural lens of the eye indefinitely.
What is Myopia?
Short-sighted eyes prevent distant objects from being seen. However, if you have good near vision. This refractive defect, which has a high hereditary component, develops during childhood and adolescence, stabilizing once this stage is overcome.
When the patient has a myopia greater than six diopters, it will be necessary to carry out periodic check-ups to rule out complications in the retina.
What is Hyperopia?
In hyperopic eyes, there is difficulty in seeing nearby objects because, unlike myopia, the image is formed behind the retina. When there is high farshigtednessduring childhood there is a risk of lazy eye, while in adults there is a greater probability of developing glaucoma.
What is Astigmatism?
Astigmatism makes both distance and near vision impossible. It is usually accompanied by myopia or hyperopia.
