Laser Eye Methods (LASIK/SMILE/PRK)

The three most common laser eye surgery methods are LASIK, SMILE and PRK:

  1. LASIK (Laser-Assisted In Situ Keratomileusis): With LASIK, a thin flap is created from the cornea and folded back. An excimer laser is then used to correct the shape of the underlying corneal layer. The flap is then put back into place. LASIK is a popular method for treating nearsightedness, farsightedness and astigmatism.
  2. SMILE (Small Incision Lenticule Extraction): With SMILE, a small, circular incision is made in the cornea through which a piece of tissue (lenticule) is removed. This is done without creating a flap. The excimer laser is then used to correct the shape of the remaining corneal layer. SMILE is a gentle method for treating myopia.
  3. PRK (Photorefractive Keratectomy): PRK involves removing the top layer of the cornea (epithelium) without creating a flap. The excimer laser is then used to correct the shape of the underlying corneal layer. The top layer of the cornea then regenerates itself. PRK is often used for thin corneas or other contraindications to LASIK.

Each of these methods has its own advantages and disadvantages, and the choice of the most appropriate method depends on various factors such as the individual eye anatomy, the type of visual impairment and the patient’s personal preferences. It is important to seek advice from an experienced eye doctor to determine the best option for your specific situation.
