Photorefractive Keratectomy (PRK)
What is PRK?
Photorefractive keratectomy (PRK) is a form of laser vision correction in which a laser eye surgeon removes the surface layer of the cornea (the epithelium) and then reshapes the corneal bed with the laser in the same way as LASIK vision correction. This technique is usually used for people whose cornea may be too thin to safely allow for the creation of the corneal flap required for LASIK.
PRK’s advantage is that it can be used for:
Patients whose cornea may be too thin to make the corneal “flap” one receives with LASIK.
Patients with irregular astigmatism or previous eye surgery. For some patients with risk of future eye trauma, such as people with certain occupations and people who do particular sports.
PRK can be used for nearsightedness, farsightedness, and astigmatism. After undergoing the procedure, most patients can return to most of their regular daily routines in 5-7 days. The improvement in vision achieved after PRK is gradual and can take longer to obtained than with LASIK, but PRK is preferred by many surgeons for particular cases. Talk to our team at BC LASIK about the PRK option.

There is no maintenance associated with the lens and they can remain in place as long as you are satisfied with your vision. If at any point your vision changes or you wish to have them removed, it can be done easily and without compromising your current vision.
