PRK AND LASEK surgery
PRK (photorefractive keratectomy) was the earliest type of laser eye surgery for vision correction, before the more popular LASIK procedure was invented. PRK is a type of refractive surgery for correcting myopia (short-sightedness), hyperopia (far-sightedness) and astigmatism, a condition where the cornea or the lens becomes curved, causing blurred or distorted vision.
Although the recovery time from PRK is a bit longer than LASIK eye surgery, PRK is still performed in cases where it is better suited to a patient’s individual needs.
Like other types of laser eye surgery, PRK reshapes the cornea using an excimer laser, allowing light that enters the eye to be properly focused onto the retina, leading to clearer vision. The main difference between LASIK and PRK lies in the first step.
During LASIK surgery, a microkeratome or a femtosecond laser is used to create an ultra-thin flap exposing the underlying corneal tissue. Once an excimer laser has reshaped the cornea, the corneal flap is smoothed back into place.
During PRK surgery, the thin outer layer of the cornea (the epithelium) is removed before the underlying corneal tissue is reshaped with an excimer laser. In this type of surgery, the epithelium is not smoothed back into place, but allowed to regenerate in the days after surgery.
LASEK surgery is very similar, and is a variation of PRK. Instead of removing the cornea’s outer epithelial layer as with PRK, during LASEK surgery it is lifted and then returned it to its position on the eye at the end of the procedure.
Generally speaking, the best candidates for LASEK or PRK surgery are patients who are not eligible for LASIK surgery, for instance those with a particularly thin cornea.
Our team of ophthalmologists and surgeons will determine your suitability for laser eye surgery and explain the different treatment options. Once your eligibility has been assessed, you’ll be able to make a fully-informed decision about undergoing the type of laser eye surgery that will give you the best possible visual outcome.
