PRK/LASEK Laser Eye Surgery
PRK (Photorefractive Keratectomy) Laser Eye Surgery is a treatment that corrects refractive error just like LASIK (Laser-Assisted in Situ Karetomileusis). Unlike the most commonly used Lasik technique, PRK method does not create a flap with the incision in the cornea and the laser starts directly from the outer surface. PRK technique laser is the process of applying the Excimer Laser to the underlying tissue by stripping the thin live tissue called the epithelium over the cornea. At the end of the surgery, a transparent and unnumbered contact lens is placed on the cornea for several days to protect the cornea surface. The process of gaining a good vision is longer compared to Lasik and can last up to 3-4 weeks. About 2-4 days after the procedure are painful and uncomfortable, the reason is that the healing of epithelial tissue is completed within this period.
Lasek technique laser eye surgery is based on the principle of removing the epithelial tissue in the eye with the aid of alcohol eye drops. Once the laser is applied, the epithelium is replaced on the eye. Although the results are safe in these two surface methods, patients may have burning, stinging and watering for 2 -3 days. Within 1 week-10 days on average, vision becomes clear. Although clearer net results can be achieved in the third month with this treatment method, patients can continue their daily life in this process in a week time without glasses.
