Astigmatism is a common refractive mistake that happens when the cornea is irregularly formed, resulting in obscured or distorted vision.

Both treatments aim to fix astigmatism by improving the cornea, however they vary in the method the outer layer of the cornea is accessed.
LASIK is the more prominent selection among individuals due to its faster healing time as well as much less discomfort contrasted to PRK. In LASIK, a slim flap is produced on the cornea using either a microkeratome blade or a femtosecond laser. The flap is after that raised, as well as an excimer laser is made use of to improve the underlying cornea. Finally, the flap is rearranged, acting as a natural plaster.
On the various other hand, PRK includes the elimination of the external layer of the cornea (epithelium) to access the underlying tissue, which is then reshaped making use of an excimer laser. As PRK does not involve the creation of a corneal flap, the healing duration is longer, as well as pain might be extra noticable in the days following the procedure. Nevertheless, PRK is frequently advised for individuals with thin corneas or other contraindications for LASIK.
