The word “laser” means “Light Amplified by Stimulated Emission of Radiation” and is used for various medical treatments and refractive surgeries such as the eye. The purpose of this intervention is to help patients with various ocular pathologies, such as myopia, astigmatism, hyperopia or presbyopia, to regain their vision.
What is laser eye surgery?
As described by the kraff eye specialists, the main objective of the LASIK Eye Surgery procedure is to stop the patient from wearing glasses or contact lenses. Likewise, this treatment allows to readapt the contour of the cornea, which will enhance the natural focus of the eye, allowing better vision.
They also explain that the most widely used technique is LASIK – laser-assisted in situ keratomileusis and corresponds to a minimally invasive treatment with excellent results.
For their part, the experts from the kraff eyemention that this technique corresponds to a type of refractive surgery in which a special cutting laser is used to modify the morphology of the cornea, which corresponds to the membrane, with maximum precision transparent and is in front of the iris.
How is laser eye surgery performed?
Specialists from theAmerican Academy of Ophthalmology explain that the intervention is performed in a room for outpatient procedures, numbing the eyes with a few drops. The instrument used in these cases is the excimer laser, which is programmed with the measurements of the patient’s eye. Then a kind of bra is put between the eyelids to prevent the patient from blinking.
As a next step, a suction ring is placed on the eye which makes it easier for it to not move and fulfills the function of flattening and lifting the cornea. It is important to note that from when the ring is put on, until it is removed, the vision darkens. Then, an automatic microsurgical device is in charge of making the layer of corneal tissue so that the excimer laser can focus on the eye and begin to work on the corneal tissue. Once finished, the surgeon returns the corneal tissue cap to the correct position, gluing it to the underlying corneal tissue. This intervention does not require points.
The intervention lasts between 20 and 30 minutes and does not require hospitalization.
