LASIK (LASer-assisted In situ Keratomileusis) with the Excimer Laser, is the most performed astigmatism surgery in the context of refractive surgery in USA. Its popularity comes from its advantages: patients recall no pain sensations and experience vision improvement as soon as a day after. This kind of surgery uses a specific instrument called microkeratome to create a thin circular layer (or flap) on the corneal surface.
the thin layer is flipped and placed on a side. Once the inner cornea portion is exposed, it’s time for the excimer laser ray to remodel it, correcting the refractive flaw. Finally, corneal tissue is replaced with no need of suture since tissues have a great adherence right a minure after this procedure.
This process is used to correct astigmatism, myopia and also hypermetropia.
This eye laser surgery is technically complex, but it by far the most comfortable for patients that want to treat myopia. This laser surgery has higher costs if compared to PRK.
