Refractive errors: how to correct them with refractive surgery

What are refractive errors and how are they corrected?

The most common refractive defects are myopia, hyperopia and astigmatism, and presbyopia or eyestrain, which appears after the age of 40 or 45, when the eye’s natural lens, or crystalline lens, loses its ability to focus on closer objects. All of these are susceptible to correction by means of different refractive surgery techniques, either laser refractive surgery or intraocular lens implantation, which offer an effective and precise solution with a good visual recovery.

Presbyopia treatment with multifocal intraocular lenses

Medical advances in ophthalmology will allow us to definitively correct presbyopia, or eyestrain, by implanting multifocal intraocular lenses. In addition, we can correct with this technique not only presbyopia, but also myopia and hyperopia, offering the patient independence from glasses and contact lenses for their daily activities. The excellent results obtained in the different refractive surgery techniques are based on an exhaustive detailed and personalized preoperative study that allows us to guide your diagnosis and offer you the best procedure in each case and thus correct your myopia, hyperopia, astigmatism and presbyopia, in the safest and most personalized way.

What are the different refractive surgery techniques?

In our clinic we have the most powerful lasers to perform the different refractive surgery techniques and eliminate myopia, hyperopia and astigmatism, in a safe, effective and definitive way. First of all, we have the Amaris excimer laser, by means of which we will cut the cornea, eliminating all the diopters so that you can do without your glasses or contact lenses. We can also use the Intralase femtosecond laser, one of the most modern lasers on the market, which allows us to perform a 100% laser cut, safe and accurate, so that visual recovery is much faster and with less discomfort. In addition, for those cases in which due to patient or corneal characteristics it is not possible to perform these procedures, we also have the PRK technique. For the last cases, in which laser technology cannot be applied, we can use intraocular lenses over the ICL lens, which provide excellent visual quality in a fast and safe procedure. Refractive surgery by intraocular lens implantation is a state-of-the-art technique, with immediate and excellent optimal results. It is especially indicated in those patients who, due to a thin cornea, very high myopia or hyperopia, or in young patients, are not good candidates for refractive surgery with laser technique. It is an outpatient surgery, with anesthesia with drops and has excellent visual results and a fast functional recovery. The technique consists in the introduction of a flexible intraocular lens between the iris and the crystalline lens, which is invisible to the naked eye and totally reversible. It also provides excellent visual quality.
