Photorefractive Keratectomy (PRK) remains a trusted and effective vision correction surgery, particularly for patients with thinner corneas or those unsuitable for LASIK. At UELC, we pride ourselves on delivering expert care, from comprehensive pre-operative assessments to advanced post-surgical support. However, like any surgical procedure, PRK comes with a spectrum of short-term and long-term side effects. Understanding these effects—and how UELC works to minimize them—can help you set realistic expectations and approach your vision correction journey with confidence.

Common Short-Term Side Effects After PRK Surgery

In the initial days following PRK, most patients experience temporary side effects as part of the natural healing process:

• Eye Discomfort or Mild Pain: It's common to feel irritation, burning, or a gritty sensation for the first 3–4 days post-surgery. UELC typically recommends over-the-counter pain relief, and protective contact lenses are often used to enhance comfort during epithelial regrowth.
  
  
• Light Sensitivity: Your eyes may be particularly sensitive to bright lights and glare during the first week. Sunglasses and dim lighting can help ease this symptom.
  
  
• Blurry Vision: Unlike LASIK, where vision often improves within 24 hours, PRK recovery involves a gradual sharpening of vision as the corneal surface heals.
  
  
• Watery Eyes or Tearing: A normal response to corneal surface disruption, typically resolving within a few days.
  
  

Long-Term Visual Recovery Timeline and Expectations

PRK patients often take longer to achieve optimal visual acuity compared to LASIK. Initial improvements may be noticed within a week, but full recovery—including reaching your best-corrected vision—can take up to 4–6 weeks, and in some cases, longer. It’s important to attend all follow-up appointments at UELC to monitor healing and adjust your care plan as needed.

Comparing PRK and LASIK Side Effects

The most significant distinction between PRK and LASIK is how the cornea is accessed:

• LASIK involves creating a corneal flap, leading to quicker visual recovery but potentially higher risk of flap-related complications.
  
  
• PRK removes the epithelium entirely, eliminating flap risks but extending the healing timeline and potentially increasing short-term discomfort.
  
  

Both procedures have similar safety profiles and long-term visual outcomes when performed by skilled surgeons using modern laser technology.

Patient-Specific Risks: Thin Corneas and Previous Eye Conditions

PRK is often recommended for patients with thin corneas, surface irregularities, or a history of eye trauma—cases where flap-based procedures like LASIK pose increased risk. During your consultation, UELC’s specialists will assess corneal thickness, eye health, and lifestyle needs to determine candidacy and develop a personalized treatment plan.

How UELC Minimizes Post-Surgical Discomfort

At UELC, patient safety and comfort are paramount. Here's how we support you:

• State-of-the-Art Laser Systems: Our excimer lasers are calibrated for precision and safety.
  
  
• Anesthetic Eye Drops: Administered before the procedure to ensure a pain-free experience.
  
  
• Therapeutic Contact Lenses: Placed after surgery to protect the eye and enhance comfort.
  
  
• Advanced Aftercare Protocols: Personalized use of anti-inflammatory drops, artificial tears, and post-operative pain management strategies.
  
  

Recovery Tips: What You Can Do to Help Healing

Your role in recovery is just as important. Here’s what we recommend:

• Use Prescribed Eye Drops as Directed: These help reduce inflammation and prevent infection.
  
  
• Avoid Rubbing Your Eyes: Even minor pressure can disrupt healing.
  
  
• Rest Your Eyes Frequently: Minimize screen time and bright light exposure.
  
  
• Protect from UV Exposure: Wear high-quality sunglasses when outdoors.
  
  
• Stay Hydrated and Well-Nourished: Supports tissue regeneration and overall healing.
  
  

Recognizing Unusual Side Effects: When to Contact UELC

While rare, some side effects may signal complications. Contact your UELC provider if you experience:

• Severe or worsening pain beyond the first few days
  
  
• Persistent hazy vision or halos that don’t improve
  
  
• Sudden decrease in visual acuity
  
  
• Signs of infection (redness, discharge, swelling)
  
  

Prompt evaluation can prevent complications and preserve your vision.

Why PRK Remains a Safe, Effective Option

Despite a slower healing curve, PRK continues to be a gold standard for patients unsuitable for LASIK or seeking flap-free correction. Its long-term benefits—stable vision, high safety profile, and suitability for a wide range of patients—make it an excellent investment in your eye health.
