What is the femto-Lasik operation of the eye?
In the not-so-distant past, the only way to correct refractive errors (myopia, farsightedness, and astigmatism) was to use glasses and contact lenses, but with the advancement of technology in the field of ophthalmology, today, to solve these problems (after a complete examination and if the eye deems necessary doctor) advanced surgical methods are used, which result in favorable results for most people; The methods that are known as general LASIK due to the use of lasers.
One of these operations, which is one of the most popular ways to remove glasses around the world, is called femtolysis, and people with farsightedness, myopia, and astigmatism can benefit from it.
The advantage of Femto-Lasik
Femtosecond laser (one of the fastest medical lasers) is used in femtolysis surgery, and for this reason, those who use this method to remove glasses from their daily life in the first days after the operation:

It is also necessary to mention that choosing the right type of surgery for each person is the responsibility of the ophthalmologist and this choice is made based on the results of a complete examination and necessary imaging.
How is femto-lasik performed?
In the femto-lasik operation, the eyes are first numbed with a special drop while you are fully conscious; Then you will be directed to the laser machine and after lying on the bed of the machine, your eyes will be kept open with a special device; So don’t worry about blinking. At this stage, the surgeon uses a femtosecond laser to make a very precise and delicate cut in the depth of about 90 to 110 microns of the cornea.
After this stage, the refractive errors of your eyes will be corrected by irradiating the surface of the cornea with excimer laser.
At the end of the procedure, the cut layer is returned to the original place and protects the lasered tissue as a natural dressing. This delicate layer heals very quickly and does not require stitches.
