LASIK, commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hypermetropia and astigmatism. It is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap that exposes the corneal stroma, then uses an excimer laser to reshape the corneal stroma in order to improve visual acuity.

How is LASIK different from PRK?
PRK scrapes away the corneal surface layer; LASIK cuts a flap in the stroma and folds it back.
Both operations use the same type of laser to reshape the cornea, and often the exact same laser. The difference is how the stroma, the middle layer of the cornea, is exposed before the laser works on it. In photorefractive keratectomy, known as PRK, the top layer of the cornea, called the epithelium, is scraped away. In LASIK, a flap is cut in the stromal layer and folded back.
