prk surgery

When it comes to vision problems, seeking care and treatment is a must. One treatment for correcting vision problems is PRK surgery, which is a type of laser eye surgery. However, determining if this treatment is right for you is dependent on your eye care needs and vision issues.

PRK Explained

PRK is a unique type of refractive surgery used by ophthalmologists and eye doctors to correct several vision problems, including astigmatism, hyperopia (i.e., farsightedness), and myopia (i.e., nearsightedness).

This surgical procedure was created before LASIK surgery and for many patients, it is a better option. Like LASIK, PRK surgery works by reshaping your cornea using a laser. This allows light into the eye and provides for clearer vision.


The main difference between PRK and LASIK surgery occurs during the first steps in the procedure. With LASIK surgery, a very thin flap is created on the cornea of the eye, exposing the corneal tissue that is underneath it. Once the corner has been reshaped with the laser, the flap is put back in place.

With PRK, the cornea’s thinner outer layer will be removed by the eye doctor and then discarded. This is not used for reshaping the cornea. Instead, it will grow back just a few days after the surgery is done.

Another small difference between these two laser surgeries is how long it takes to recover afterward. While PRK does have a longer recovery time because the outer layer of the cornea must regrow, it is still an effective treatment option.

The Top Benefits Offered by PRK

While the recovery time for PRK surgery is slightly longer, there are a few benefits that are offered by this procedure over LASIK.

The top benefits include:

  • The stroma’s entire thickness is available for treatment since the procedure does not require the creation of a flap.
  • Patients with thinner corneas can use PRK surgery but may not be eligible for LASIK surgery.
  • If someone has had LASIK surgery before, but now their cornea is thinner, PRK surgery can still be used if their vision is not completely clear.
  • No corneal flap complications with PRK.
  • Reduced risk of removing excessive cornea compared to LASIK treatment.

Contact Your Eye Doctor to Learn More

If you are interested in PRK surgery or believe it would help to improve your vision, schedule an appointment. Your eye doctor can evaluate your current vision situation and help you decide if PRK surgery is the right solution.

While it may not be the right vision correction procedure for everyone, it offers an array of benefits over LASIK, which makes it a smart option for those who want clearer vision. Being informed is the best way to know if this procedure is right for you.
