Is PRK Eye Surgery Safe?
Most of the patients we treat are generally familiar with LASIK. However, there’s another highly effective alternative known as PRK (Photorefractive Keratectomy). PRK has been safely used for over three decades and is a preferred option for patients with certain eye characteristics, such as thin corneas. But is PRK eye surgery safe?
The short answer is that PRK is a safe, proven, and reliable procedure for the right individual. It does involve a slightly longer recovery period than LASIK, but it also eliminates some of the risks that may occur as a result of flap-based surgery. Understanding how it works and why it’s chosen in specific cases will give you complete confidence in your decision.
What Is PRK and How Does It Compare to LASIK?
PRK was the first type of laser eye surgery developed and still to this day is a popular choice, especially in cases where LASIK may not be the right treatment option.
Here’s how it compares:
| Feature | PRK | LASIK | SILK |
|---|---|---|---|
| Flap creation | No | Yes (corneal flap is created) | No |
| Healing time | 1–2 weeks for vision clarity | 24–48 hours | 24–48 hours |
| Ideal for thin corneas | Yes | Not recommended | Not recommended |
| Risk of flap dislodgement | None | Possible with trauma or pressure | None |
| Long-term outcomes | Excellent | Excellent | Excellent |
Understanding the Main Benefits of PRK Surgery
It’s Safe for Thin Corneas
PRK will often be the first option discussed for patients who are not suitable for LASIK or SILK because of thin or irregularly shaped corneas. The procedure doesn’t involve creating a corneal flap or removing a lenticule to leave more of the corneal structure intact. This preserves its strength and stability.
Proven to be Safe and Effective
PRK has been studied extensively over the years, and it’s produced consistently strong outcomes. Clinical research shows that it delivers excellent long-term vision correction and with that comes a very low risk of serious complications.
No Corneal Flap Required
Unlike LASIK, PRK does not involve creating a flap in the cornea. This reduces the risk of flap-related issues like dislodgement or inflammation beneath the flap (DLK), making for a simpler structural procedure with less to go wrong.
Permanent Vision Correction
For the right individuals, PRK can help you achieve a permanent improvement in unaided vision. It reduces or eliminates the need for glasses or contact lenses entirely.
Suitable for Active Lifestyles
Because PRK leaves no flap, it’s well-suited to patients involved in contact sports, military roles, or high-impact physical activities, where trauma to the eye might otherwise risk flap displacement.
How PRK Eye Surgery Works
Pre-Surgery Assessment
Before undergoing PRK, every patient will carry out a comprehensive pre-operative assessment. Our specialists will conduct advanced diagnostic testing to evaluate your eye health, corneal thickness, and prescription stability. Your surgeon will also review any medical history, screen for conditions such as dry eyes or irregular corneas, and talk through your own personal vision goals. This stage is essential to confirm your suitability for PRK and to set realistic expectations about your recovery period.
The Procedure
PRK is a quick but precise procedure that takes around 10–15 minutes per eye to complete. It begins with pre-surgery preparation where anaesthetic, antibiotic and anti-inflammatory eye drops are applied to the eye. An icepack is also held over the eye for 10 minutes.
The surgeon gently polishes away the outer layer of the cornea (the thin, transparent part of the eye) and uses a cool beam of laser light to sculpt the corneal tissue into a new shape to correct the refractive error. Next, a ‘bandage’ contact lens is placed on the eye to promote comfort and healing. Patients can expect the surface layer to grow back over the next few days, after which the bandage contact lenses will be removed.
Post-Surgery Recovery
Recovery from PRK takes a little longer than flap-based procedures like LASIK but remains straightforward. The epithelial layer will heal within 3 to 4 days and in this time it’s fairly common to experience some discomfort, grittiness, or light sensitivity. Vision usually improves gradually over the week to functional vision to drive a car or watch TV, and most patients will experience full clarity in the following weeks. Follow-up appointments are scheduled to monitor healing progress and any discomfort is managed with prescribed lubricating drops, anti-inflammatory medications, and protective eyewear where necessary.
