The Lasik technique is the most widely used today for the correction of refractive errors and is fully consolidated after more than twenty years of application. It is a surgical procedure framed within laser refractive surgery that is used to correct refractive problems of the eye (myopia, hyperopia and / or astigmatism) and improve the quality of life of the patient.
What is the Lasik technique?
The correction of refractive problems using the Lasik technique (Laser Assisted in Situ Keratomileusis) is a simple, fast, safe, painless and personalized operation that takes place in three steps:
- Using an instrument specially designed for this type of intervention, the microkeratome, the doctor lifts a thin layer of corneal tissue similar to a lens (flap). In this way, it frees the ocular area where the laser will act to modify the shape of the cornea.
- The surgeon applies the Excimer laser (ultraviolet laser) on the intermediate layer of the cornea to mold it for a period of time between 5 and 45 seconds, depending on the type and magnitude of the error or refractive errors to be treated. The laser has a safety mechanism that controls eye movements, known as an eye-tracker, which allows the impacts to be directed to those parts of the cornea that must be re-modeled to correct the refractive defect.
- The corneal tissue is repositioned, reattached without the need for stitches so that it heals naturally.
Before performing the intervention with the LASIK Eye Surgery, the patient undergoes a meticulous and rigorous study to know its graduation and from which data are extracted about the shape and function of the cornea. This study, which includes a large number of painless and non-invasive tests, is carried out during the first preoperative consultation and all the information obtained from the anatomy and visual situation of the patient is transmitted to the laser, so the kraff eye institute Lasik treatment it is specially designed for each person.
What advantages does it offer?
The Lasik technique offers multiple advantages from the point of view of the patient who wants to correct their diopters and free themselves from glasses and contact lenses:
It is the refractive surgery procedure that accumulates the largest number of people operated on in the world.
It is very accurate, safe, effective and predictable.
It allows a quick recovery of visual acuity that, usually, begins to be noticed immediately.
