When it comes to achieving clear and lasting vision, there are numerous eye treatment options available, but few offer the same combination of effectiveness and safety as PRK surgery. For those seeking an alternative to LASIK, or for those who are not ideal candidates for LASIK, PRK surgery is an excellent solution. At SNU Eye Clinic, located in the heart of Gangnam, Seoul, this non-invasive laser eye surgery is performed with precision and care by expert ophthalmologists who specialize in refractive surgery. In this article, we will explore how PRK surgery works, its benefits, and why SNU Eye Clinic is a top choice for patients seeking corrective eye surgery.
What is PRK Surgery?
Photorefractive Keratectomy, or PRK, is a laser eye surgery cost eye surgery that aims to correct common refractive vision problems, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It is a form of refractive surgery that works by reshaping the cornea, the clear front surface of the eye, to improve how light is focused on the retina, which in turn enhances vision.
PRK differs from LASIK (Laser-Assisted in Situ Keratomileusis) in that it does not involve creating a flap in the cornea. Instead, the surgeon removes the thin outer layer of the cornea (the epithelium) and uses an excimer laser to reshape the corneal tissue beneath it. This process results in permanent changes to the curvature of the cornea, allowing light to be properly focused on the retina and improving vision.
One of the main benefits of PRK surgery is that it does not require the creation of a flap, which can sometimes lead to complications in LASIK patients. As a result, PRK is considered to be a safer alternative for certain individuals, particularly those with thin corneas or those who have concerns about the risks of LASIK surgery.
How Does PRK Surgery Work?
The PRK procedure at SNU Eye Clinic begins with a thorough eye examination to determine if the patient is a good candidate for the surgery. The ophthalmologists at the clinic take into account the patient’s eye health, vision needs, and medical history before recommending the procedure.
Once the patient is deemed suitable for PRK surgery, the procedure itself typically takes about 15 to 30 minutes. The first step involves administering anesthetic eye drops to numb the eyes, ensuring that the patient feels no pain during the procedure. Next, the surgeon carefully removes the epithelium, the outermost layer of the cornea. This is done using either a laser or a mechanical instrument.
After the epithelium has been removed, the excimer laser is used to reshape the underlying corneal tissue. The laser is highly precise, targeting only the areas that need reshaping. The laser energy removes microscopic layers of tissue, correcting the refractive error and ensuring that light is focused properly onto the retina.
After the laser treatment is complete, a special bandage contact lens is placed on the eye to protect the healing surface. The patient is typically required to wear this contact lens for a few days as the cornea heals. Although the recovery time is longer than LASIK, PRK surgery is generally a safe and effective method for vision correction.

Who is a Candidate for PRK Surgery?
PRK surgery is suitable for individuals with nearsightedness, farsightedness, or astigmatism who are seeking a reliable solution for correcting their vision. However, not everyone is a candidate for PRK surgery. To be eligible, patients must meet certain criteria, including:
- Stable Vision: Candidates should have a stable prescription for at least one year before undergoing PRK surgery.
- Healthy Eyes: Patients should have no history of serious eye conditions, such as glaucoma or cataracts.
- Good Overall Health: Candidates should be in good overall health and free of systemic conditions that could affect healing, such as autoimmune disorders.
Recovery After PRK Surgery
While the PRK procedure is highly effective, the recovery period can take longer compared to LASIK. After surgery, patients may experience some discomfort, including a gritty or dry feeling in the eyes. These symptoms typically subside within a few days, but full recovery can take up to several weeks.
During the recovery process, it is essential for patients to follow all aftercare instructions provided by their ophthalmologist at SNU Eye Clinic. This includes using prescribed eye drops, avoiding rubbing the eyes, and attending follow-up appointments to monitor healing.
