What is PRK (Photorefractive Keratectomy) Vision Correction?

PRK (Photorefractive Keratectomy) is a vision correction method based on the principle of reshaping the cornea's curvature, similar to LASIK. However, it differs in its surgical procedure. PRK is a technique that dates back to the 1980s, preceding the development of LASIK, and it remains popular due to its permanent and effective results.

PRK is suitable for individuals with nearsightedness (myopia), nearsightedness in one eye, or astigmatism. It can correct nearsightedness up to approximately -5.00 diopters and astigmatism up to -2.00 diopters. It is particularly recommended for those with thin corneas or dry eye syndrome who may not be candidates for LASIK, as LASIK requires the creation of a corneal flap, which can worsen dry eye symptoms.

What Vision Problems Can PRK Correct?

PRK is a safe and effective vision correction alternative, especially for individuals who are not suitable for traditional LASIK. PRK can help correct the following vision problems:

👀 Nearsightedness up to -5.00 diopters 
👀 Nearsightedness in one eye (anisometropia) 
👀 Astigmatism up to -2.00 diopters

How Does PRK Differ from Standard LASIK?

The difference between PRK and LASIK lies in the surgical method and the part of the cornea the laser treats. With PRK, the surgeon gently removes the cornea's outer surface layer (the epithelium) before applying the laser to reshape the cornea. With LASIK, the surgeon creates a thin flap in the cornea, lifts it, and applies the laser to the underlying corneal tissue.

Who Should Choose to Have PRK?

For those seeking a safe and effective vision correction option, PRK is an excellent choice. Ideal candidates for PRK meet the following criteria:

✅ Must be 18 years of age or older. 
✅ Must have a stable vision prescription for at least one year. 
✅ No history of corneal diseases, such as corneal abrasions or recurrent erosions. 
✅ No systemic diseases that could affect eye surgery, such as uncontrolled diabetes. 
✅ Have nearsightedness or astigmatism within the correctable range. 
✅ Suitable for individuals with thin corneas, difficult-to-treat dry eyes, or irregular corneal shapes. 
✅ Some patients with glaucoma may be eligible but require a thorough evaluation and consultation with a doctor first. 
✅ Ideal for individuals pursuing careers with strict vision requirements where flap-related injuries are a concern, such as pilots, police officers, or military personnel.

What to Know and How to Prepare Before PRK

To ensure a smooth and safe PRK procedure, candidates should follow these pre-operative instructions:

⏩ Discontinue soft contact lens use for at least 3 days before the eye examination and the day of the procedure. ⏩ Discontinue hard contact lens (RGP) use for at least 7 days before the eye examination and the day of the procedure. 
⏩ You may wear your regular eyeglasses. This helps prevent contact lenses from compressing the cornea, allowing it to return to its natural shape. 
⏩ Plan to take at least 5-7 days off from work starting from the day of the PRK procedure to allow for adequate recovery time. 
⏩ Do not drive yourself on the day of the examination. You should arrange for someone to accompany you, as your vision will be blurry for about 4-6 hours after the exam. 
⏩ Be cautious when traveling home after the examination, as your vision may be impaired during this time. 
⏩ If you notice any eye abnormalities before or on the day of your appointment, inform the staff before the examination begins. 
⏩ Avoid using perfumes, oils, hair gels, roll-on deodorants, or any scented sprays on your body and clothing, as these can interfere with the laser's performance. 
⏩ Do not wear makeup or apply any creams to your face on the day of the procedure. 
⏩ Wear a button-front shirt for convenience when changing. 
⏩ Bring sunglasses with you to protect your eyes from bright light after the procedure. 
⏩ You may eat as usual, but avoid tea and coffee before the procedure.

Frequently Asked Questions about PRK (FAQ)

Here are some popular questions about PRK with clear and complete answers to help you make an informed decision.

How long does it take to see results after PRK? 
Vision typically starts to become clearer within about 1 week, but in some cases, it may take longer than 2 weeks to achieve full visual clarity.

Can PRK be performed a second time? 
Yes, a PRK enhancement can be performed if it is deemed necessary and only after a recommendation from your ophthalmologist.

Can I have PRK if I have thin corneas? 
Yes, PRK is often the recommended procedure for people with thin corneas. Because it does not require the creation of a corneal flap, it is an excellent option for those with thin corneas or other specific vision limitations.
