What is photorefractive keratectomy (PRK) surgery, and how does it work? Photorefractive keratectomy (PRK) is a refractive surgery performed using a laser. A refractive issue occurs when your eyes do not bend light correctly, preventing you from seeing clearly. It’s possible that you won’t need your glasses or contact lenses after your PRK or that you’ll only need them for particular activities like reading or driving at night.
- What Is the Purpose of Photorefractive Keratectomy (PRK)?
As you are aware, there are different types of eye surgery, and you may be asking yourself what the difference between PRK vs LASIK. Well, this article talks in-depth about PRK, but later on, you will see an elaborate difference between the two. To cure refractive defects in the eyes, a photorefractive keratectomy is done. This technique enhances the way light rays are focused on your retina by changing the curvature of your cornea using a laser. If you’ve been diagnosed with any of the following eye problems, you may require a PRK: Myopia (nearsightedness), Hyperopia (farsightedness), Astigmatism (the shape of your eye that causes blurry vision).
- Advantages of PRK Surgery
- PRK Is an Excellent Option for Patients Who Have Thin Corneas
PRK is the only laser eye surgery option accessible to a patient in some instances. SMILE and LASIK may not be possible if your corneas are too thin. Short-sightedness, long-sightedness, and astigmatism are all treated with PRK. However, long-sightedness is not yet treated with SMILE (difficulty seeing things up close).
- PRK Is Beneficial to Those Who Participate in Contact Sports or Work in Physically Demanding Employment
Because PRK does not make an incision in the cornea, it causes less structural damage. This means it’s ideal for persons who participate in contact sports or work in physically demanding jobs like the military. A corneal ‘flap’ is created during the LASIK process, which can become detached if the patient receives a substantial blow to the head.
- PRK Has A Decreased Risk of Infection or Dry Eye
Because PRK is less intrusive, it has a decreased risk of infection and does not interfere with the eye’s regular watering. This reduces the risk of dry eye, which can be particularly noticeable after LASIK.
- TransPRK Is the Only Method That Does Not Require Any Contact
All laser eye surgery techniques needed an instrument of some kind to come into contact with the eye before TransPRK (Transepithelial PRK). TransPRK is performed in the same way as traditional PRK, except that the SCHWIND AMARIS 750 laser eliminates the need for suction, blades, or alcohol contact with the eye. This means it’s less intrusive and easier on the eyes.
- PRK Is the Most Cost-Effective Procedure
In general, PRK laser eye surgery is less expensive than other laser eye surgery options. This is mainly because PRK was the first and most widely available technique determined by demand and supply economics. People typically choose LASIK or SMILE over PRK because of the lengthier recovery durations, even though the final vision quality is different.
Many patients choose PRK eye surgery because it is the only operation that fits their lifestyle, job, or budget or because it is the only procedure recommended by their doctor. If PRK is the treatment of choice, you may rest assured that it will provide you with identical aesthetic results at a cheaper cost and with a little more time to relax in recovery.
- PRK Vs. Lasik
You may be asking yourself the difference between PRK vs LASIK. Both PRK and LASIK are laser eye surgery procedures in which the cornea is modified to correct vision. Nearsightedness, farsightedness, and astigmatism may all be fixed with any of these lenses. Although PRK has a more extended history, both approaches are still commonly employed today.
The procedure to modify the corneal tissue to improve vision differs by technique. The cornea’s epithelium, or top layer, is completely removed during PRK. Your eye surgeon will then use lasers to reshape the other corneal layers and correct any curvature anomalies. On the other hand, LASIK creates a small flap in the epithelium using lasers or a tiny blade. To access the tissues beneath, your eye surgeon will lift the layer and shift it to the side. The cornea will be reshaped with lasers. They’ll place the bandage on when the procedure is finished.
- Minor effects Of PRK
You should anticipate being in pain or discomfort for up to three days after PRK surgery. In most cases, over-the-counter pain relievers are adequate to alleviate the discomfort.
Ask your doctor for pain medication if you’re worried about pain or are experiencing more than you can bear. It’s also possible that your eyes are inflamed or watery. While your eyes are recovering, you may notice that they are more sensitive to light. Some patients, especially at night, see halos or flashes of light for days or weeks after PRK.
For a short time following surgery, you may have corneal haze, a foggy coating that can considerably limit vision. PRK surgery is not without danger, even if it is deemed safe. Loss of eyesight that cannot be restored with eyeglasses or contact lenses is one of the dangers.
The PRK eye surgery is a quick treatment that requires little downtime. It can help with astigmatism, nearsightedness, and farsightedness. Keep in mind that you should have realistic expectations for your PRK. After the procedure, you may still require your glasses or contact lenses. As soon as you find issues with your eyes, talk to your optometrist and ophthalmologist about your concerns and choices.
