For those who are nearsighted, farsighted, or have astigmatism, traditional corrective lenses like glasses and contacts can be inconvenient. While LASIK is a popular solution, it’s not always suitable for everyone. Khanna Vision Institute offers Photorefractive Keratectomy (PRK) and Custom Wavefront PRK, advanced laser vision correction procedures that provide an alternative path to clear, natural vision without the need for glasses or contacts.
Photorefractive Keratectomy (PRK) is the original laser eye surgery from the nineteen eighties. It’s the original laser-based procedures which was invented before Lasik. It corrects all common vision issues such as myopia or near-sightedness, hyperopia or farsightedness, and astigmatism. Even today it still remains a great option for certain candidates due to its safety and effectiveness. Unlike LASIK, PRK reshapes the cornea without creating a flap, making it ideal for those with thinner corneas or a little abnormality in cornea shape who might not qualify for LASIK nor want EVO ICL.
What PRK Offers?
PRK offers a lasting way to sharpen your vision without glasses or contacts. It is especially recommended for those in contact sports like basketball, football, boxing. It gives you the freedom to live an independent natural life. You may want to eliminate glasses and contacts if you are an active sportsperson, outdoor person, follow all the latest fitness trends, living your aesthetic life, or just want the convenience of clear vision without the hassle of contacts and glasses.
PRK vs LASIK: What’s the Difference?
Both PRK and LASIK reshape the cornea to improve your vision, but here’s how they differ:
PRK doesn’t create a corneal flap, making it suitable for people with thinner corneas or those involved in high-contact activities.
LASIK involves creating a corneal flap, which results in quicker visual recovery but may not be suitable for those with thinner corneas.
If you’ve been researching vision correction, you may have noticed that PRK can take longer to heal than LASIK. This is true; however, PRK is often recommended for those who want a “no-flap” option or have unique eye needs. PRK is sometimes called a “foundation” laser procedure because of its simplicity and stability over time.
Why PRK Might Be Perfect for You
If you’re thinking about laser vision correction but want to know which procedure is right for you, here’s what makes PRK stand out, especially if you’re in the 18–35 age range:
1. No Corneal Flap: In LASIK, a small flap is created on the cornea, which heals but may cause issues for people with active lifestyles. With PRK, the outer layer of the cornea (epithelium) is removed and grows back naturally. If you’re into sports, fitness, or any activity where eye safety is a factor, PRK might be the right choice.
2. Stability and Longevity: PRK has been around since the late 1980s and is a proven, stable option for correcting vision. Once your eyes heal, the correction is permanent, making it a great investment in yourself for decades to come.
3. Clear Vision Without Compromise: For those with thin corneas or unique eye shapes that don’t work with LASIK, PRK is a safe and effective alternative. A thinner cornea is common in people who are genetically predisposed or those who have worn contact lenses for many years.
4. Thin Cornea: If your Cornea is thinner than 475 microns PRK would be safer for you. Normal Corneas are over 500 microns. Even if the cornea is normal thickness but your prescription is high for LASIK, PRK would be a good choice.
5. Abnormal shape of Cornea: IF there is asymmetry of the shape of the cornea, PRK becomes the superior choice.
The PRK Procedure: What to Expect
Knowing what to expect can make a huge difference, especially if this is your first big procedure. Here’s a breakdown of what happens during PRK:
1. Pre-surgery Consultation: The process starts with a thorough eye exam. Your doctor will measure your eyes, check your vision, and discuss your medical history. They’ll also look at the thickness of your cornea to make sure PRK is right for you.
2. The Procedure: On the day of surgery, you’ll be given numbing eye drops to ensure your comfort. Using an advanced laser, your surgeon will carefully reshape the cornea’s surface, correcting the way light enters your eye. The procedure itself takes about 10–15 minutes per eye.
3. Recovery and Healing: Since the outer layer of the cornea needs to grow back, the healing process is slightly longer with PRK than with LASIK. You may experience mild discomfort for a few days, but your doctor will give you drops to manage any irritation. Clear vision typically begins to return within a few weeks, and full visual acuity may take one to three months to settle in.
4. Results: By the time your healing is complete, you’ll be enjoying sharp, natural vision that can last a lifetime. Many people who undergo PRK achieve 20/20 vision or better, making a real impact on daily life, work, and adventures.
