LASIK vs PRK: Which is Right for Me?

October 26, 2020


PRK and LASIK are two of the most popular options for vision correction. They both can help patients get rid of their contact lenses and glasses, resulting in years of crystal-clear eyesight. But what’s the difference between PRK and LASIK, and which procedure is best for you?

Read our guide below to find out!


The biggest difference between PRK and LASIK is how they are performed. Photorefractive Keratectomy, or PRK, involves removing the cornea’s outer layer to expose the tissue underneath. Then, an excimer laser is used to reshape the cornea. Once the surgery is complete, the doctor places a soft contact lens on the eye to keep it protected. The lens can also help the cells of the cornea’s outer layer grow back.

LASIK also uses an excimer laser to reshape the cornea in order to correct eyesight. However, instead of removing the outer layer, the surgeon creates a flap in the eye. The LASIK flap is then lifted to reveal the underlying corneal tissue. When the procedure is finished, the flap is put back into place, which allows your eyes to heal naturally.


PRK and LASIK are quick and easy surgeries that provide excellent results. However, you will still need to consider the pros and cons of both to decide which option is best for you.

    • PRK is an innovative solution for many patients, including those who may not qualify for LASIK. In fact, one of the best things about it is that most people can be a candidate for the procedure.
    • While minor, there are a few disadvantages to PRK that you should keep in mind. For example, this procedure may require longer recovery time. Since the outer layer of the cornea will be removed during the surgery, it can take a few days for the cells to regenerate and cover the surface of the eye.
    • You can also experience hazy vision as well as discomfort in the days following the procedure. To help you deal with these common recovery symptoms, the doctor will prescribe eye drops to reduce irritation and promote healing.
    • Improvements in vision will also be gradual as the cornea’s outer layer grows back. With that said, your eyesight may still be a little blurry for a few days after your surgery.
    • Unlike PRK, LASIK has a very fast recovery time. Typically, patients can see clearly as early as the morning after the surgery. You can also resume normal activities within a day or two depending on how your eyes are healing.
    • For a little while after the procedure, you may also experience dry eyes and difficulty driving at night, because of the halos in your vision around lights. However, how long patients will experience these symptoms will depend entirely on the person and their eyes.
    • Furthermore, not everyone will be considered a candidate for LASIK.


The best way to decide between PRK and LASIK vision correction is to consult an eye doctor. They will go over your medical history to determine if you qualify for either of these procedures and help you decide which one is the best option for your specific situation.
