The LASIK technique:

LASIK (Laser-Assisted In Situ Keratomileusis) is a vision correction procedure that can be used to treat nearsightedness, farsightedness, and astigmatism. This technique uses an excimer laser to reshape the cornea, which is the first clear surface of the eye that helps focus light onto the retina.

Before the procedure, the patient undergoes a series of complete eye exams, quick and completely non-invasive, to evaluate his/her suitability for the procedure. This series of exams includes a measurement of the curvature of the cornea, a corneal topography, Tomography with Pentacam and with the MS39 (laser tomograph), of the depth of the anterior chamber of the eye and the diameter of the pupil in various light conditions (low, medium, high brightness), OCT exam of the macula and the optic nerve, Measurement of intraocular pressure and thickness of the cornea, Check of the central and peripheral retina, evaluation of tear production. All these exams are usually performed in a short time without invasive procedures and constitute a careful and timely evaluation of the general ocular health, allowing a very precise judgment to be expressed on the possibility of undergoing Lasik surgery for the correction of the refractive defects present.

It should be noted that today, it is possible to correct a very wide variety of refractive defects, albeit with different techniques. Therefore, in the case that, for example, the amount of myopia is too high for the LASIK technique, it will be possible to evaluate an alternative technique, which does not thin the cornea and which, through the implantation of intraocular lenses (ICL), allows the correction of up to 18 diopters of myopia associated with astigmatism of up to 7 diopters.

During the LASIK procedure, a microkeratome is used to create a thin flap on the surface of the cornea, or this flap can be created using another laser: the FEMTOLASER. This flap is gently folded to expose the underlying corneal tissue. The excimer laser is then used to reshape the cornea, removing minute amounts (MICRON = THOUSANDTHS OF A MILLIMETER) of tissue to correct the irregular curvature of the eye.

After the laser treatment is complete, the corneal flap is carefully replaced on the surface of the eye. The flap will naturally adhere to the underlying tissue and heal quickly.

The only sensation you may feel is a slight pressure during LASIK surgery, which is generally well tolerated. The procedure takes only a few minutes for each eye, and you can go home the same day, without any bandages.

LASIK vision correction is a safe and effective procedure that provides remarkable results for the correction of nearsightedness, farsightedness, and astigmatism.

Of course, as with any medical procedure, preoperative conditions must be considered, as will be evident from the preliminary examination evaluations. It will be important to be able to discuss every detail with the patient, before proceeding with the surgery. Our doctors and in particular the surgeon will be happy to give all the details about the patient's situation and the LASIK procedure.

For over thirty years now, Centro Vista has been performing LASIK surgeries, we were the first in Sardinia to adopt this technique. Thousands of cases have been treated and they are increasing every year.
