What is PRK Laser Eye Surgery? Photorefractive keratectomy (PRK) is another option for laser vision correction similar to LASIK laser eye surgery. Just as with the LASIK procedure, your Ophthalmologist uses the excimer laser to correct your vision however there is no flap created but only a small portion of the top layer of the cornea moved in order to sculpt the cornea. How Do I Know if I am a Candidate for PRK vs LASIK Eye Laser Surgery? You and your Ophthalmologist will discuss your options thoroughly following your eye exam. If your corneas are too thin to make the larger flap as in LASIK, PRK may be the recommended choice. In the case of previous LASIK eye laser surgery or if other eye health concerns exist, your surgeon may choose PRK as the better option.
