LASIK (Laser-Assisted In Situ Keratomileusis)
Definition - What does LASIK (Laser-Assisted In Situ Keratomileusis) mean?
LASIK (laser-assisted in situ keratomileusis) is a laser eye surgery that is performed in order to correct refractive errors and it is considered one of the most popular laser eye surgeries. With this method, the correction of the refractive error is not performed on the surface but inside the cornea.
TheConsultation explains LASIK (Laser-Assisted In Situ Keratomileusis)
The surgeon initially creates a thin superficial flap of corneal tissue with the help of a special tool, the microkeratome. This flap isn't completely cut off, but it remains united with the cornea on one side. Then the flap is lifted, revealing the inner layers of the cornea. Through this flap, the ophthalmologist uses the excimer laser, in order to reshape the cornea and correct the refractive error.
Finally, the surgeon puts the flap back in place, without the need for any sutures. In order to eliminate the pain, numbing eye drops are applied before surgery, while the procedure takes a few minutes for each eye to complete and the patient can return home the same day. As with other laser eye surgeries, the results are permanent.
