Laser Vision Correction
PRK Eye Surgery
Photorefractive Keratectomy or PRK is a form of laser vision correction where a surgeon removes the cornea's surface layer, also known as the epithelium. They will then reshape the corneal bed with the laser, similarly to LASIK.
This specialized technique is usually reserved for patients whose cornea may be too thin to safely allow for the creation of the corneal flap essential for LASIK surgery. Sometimes, patients may come into UELC hoping to have LASIK surgery and are instead directed to PRK. This is an assessment that is made on a case-by-case basis.
Key similarities between PRK and LASIK surgery include: Both are used to correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.Both are known to be equally safe procedures. The visual results with both procedures are the same.
PRK Eye Surgery
Photorefractive Keratectomy, commonly known as PRK surgery, is a type of laser eye surgery that is used to correct vision problems caused by refractive errors such as nearsightedness, farsightedness and astigmatism. This surgical procedure involves reshaping the cornea, which is the clear dome-shaped outer layer of the eye, to improve visual acuity. PRK surgery was first introduced in the early 1980s and has been continuously improving over time.
How PRK Surgery Works
During PRK surgery, an excimer laser is used to reshape the cornea. The surgeon first removes the thin outer layer of the corneal tissue, known as the epithelium. This layer grows back naturally within a few days after surgery. Then, the excimer laser is used to precisely remove small amounts of tissue from the underlying corneal tissue. The goal of the surgery is to change the shape of the cornea so that light can be properly focused on the retina, resulting in improved vision.
Advantages and Disadvantages of PRK Surgery
One of the main advantages of PRK surgery is that it does not involve creating a flap in the cornea like other types of laser eye surgeries such as LASIK. This makes it a better option for people with thinner corneas or other eye conditions that may make flap creation risky. PRK surgery also has a lower risk of complications compared to other forms of laser eye surgery.
One disadvantage of PRK surgery is that the recovery period can be longer than other laser eye surgeries. The outer layer of the cornea takes a few days to regenerate, during which time the patient may experience discomfort and blurry vision. It may take a few weeks for full recovery and visual acuity to be achieved.
The Bottom Line
PRK eye surgery is an effective and safe option for correcting refractive errors and improving vision. It offers advantages such as a lower risk of complications and suitability for patients who may not be eligible for other types of laser eye surgery. However, it may also have a longer recovery period compared to other procedures. It is important to consult with the experienced team at UELC to discuss the potential risks and benefits based on your individual needs and circumstances. If you have been struggling with vision problems caused by refractive errors, PRK surgery may be a viable solution to help you achieve clear and improved vision. Take the first step towards better vision and explore PRK surgery with UELC today. Your eyes deserve the best care and attention, so don't hesitate to invest in your visual health.

FAQ
Your Questions Answered
What is the difference between Lasik and PRK?
PRK and LASIK are very similar, however, they are difference in one major way. During LASIK, a flap is created on the topmost layer of the cornea which allows the cornea to be reshaped before the flap is set back down. During PRK, on the other hand, the epithelium is removed to allow the laser to reshape the cornea. This tissue will grow back as part of the healing process.
Who are ideal candidates for PRK?
Ideal candidates for PRK are people who would like to achieve a great vision without reliance on corrective lenses. They experience refractive errors (myopia, hyperopia, astigmatism).If you are considering laser eye surgery but fear that you may be too old, you’ll be pleased to know that there is no age limit. Once you’ve reached the minimum recommended age, you can undergo laser vision correction at any point in your life. While you are never too old for this procedure, there is a lower age limit requirement. It is not recommended for those under the age of 18, as their eyes are still developing, and their eyesight will likely continue to change as they age. After 18, surgery may be considered for those under 21 as long as they have had a consistent prescription for two or more years.
What is the age limit for PRK eye surgery?
18 years old and above is an ideal age range. Your general health and cornea must be healthy.
Is PRK surgery painful?
Some discomfort or mild pain can be expected for around 3 days following PRK Laser Vision Surgery. Over-the-counter pain medications are effective for pain management in most cases.
How should I prepare for surgery
Before the Surgery: In preparation for PRK, please avoid the use of contact lenses for several days. Our eye surgeon will conduct various examinations to calculate and determine the proper course of treatment.
Immediately Before the Procedure: Before surgery, our specialists will prepare you with anesthetic drops to numb the eye.
During the Eye Surgery: Our expert eye surgeon will perform the procedure with utmost comfort, using the appropriate laser and other required technologies. UELC has state-of-the-art machines to ensure you receive the best results.
After the Laser Vision Correction: Post-surgery, you may experience sensitivity to light and slight discomfort immediately following treatment. A follow-up appointment will be scheduled to observe and analyze your progress.
What is refractive error?
Refractive error is a common eye disorder that occurs when the shape of the eye does not allow light to focus directly on the retina. This can result in blurry or distorted vision. The three most common types of refractive error are myopia (nearsightedness), hyperopia (farsightedness) and astigmatism.
How much does PRK eye surgery cost?
The cost of PRK surgery varies depending on factors such as the location, the surgeon's fees, and any additional procedures required. On average, PRK surgery can cost anywhere from $1,500 to $2,500 per eye. In some cases, insurance may cover a portion of the cost if the surgery is deemed medically necessary.
