The Truth About Healing: A Short-Term Sacrifice for Lifelong Stability

At EyeLaser Vienna, we don’t sugarcoat anything. Transparency is our top priority. While the procedure itself is absolutely painless, Trans-PRK differs significantly from Femto-LASIK in the healing phase.

Why does it hurt after surgery?

The laser removes the top cell layer (epithelium). Fine nerve endings lie in this layer. Until the body has regenerated this layer (which takes about 3 to 5 days), these nerve endings are unprotected. This is comparable to a harmless but painful abrasion.

Haze Prevention: Our Strict Medical Protocol

The biggest risk with surface treatments is so-called “haze”—a milky clouding of the cornea due to scarring. To prevent this, at EyeLaser we implement an uncompromising medical protocol on three levels:

  1. Intraoperative (Mitomycin C): While you’re still on the operating table, we apply the medication Mitomycin C (MMC) to the cornea for a few seconds. It blocks scar formation at the cellular level.
  2. Postoperative (Cortisone & Vitamin C): You receive a precise drop schedule with cortisone-containing eye drops. We also recommend high-dose vitamin C (e.g., 1000 mg/day), as it massively supports healthy collagen formation in the cornea.
  3. Lifestyle (100% UV Protection): UV radiation is the main trigger for haze. You must wear high-quality sunglasses outdoors for the first 3 to 6 months—even under cloudy Viennese skies.

The Big Method Comparison: When Is Trans-PRK the Best Choice?

Ein Mann während einer Augenuntersuchung in der Eyelaser-Klinik
Feature / Method Trans-PRK (SmartSurfACE) Femto-LASIK 7D SmartSight (Lenticule)
Incision Technique 🥇 No incision (“No-Touch”) Flap incision (approx. 20 mm) Minimally invasive (< 3 mm)
Biomechanical Stability 🥇 Maximum (100% intact) Very high (flap heals) 🥇 Maximum (No flap)
For Extremely Thin Corneas? 🥇 Yes (The safest choice) No Conditional (tissue limit)
Pain-Free After Surgery 🔴 Painful (Day 1-3) 🥇 Excellent Excellent
Visual Recovery (Sharp Vision) Longer (sharp from approx. week 1-2) Fastest (on day 1) Very fast (1–2 days)
Downtime (Work) Approx. 4 to 5 days 1 day 1 to 2 days

The EyeLaser Suitability Check: Traffic Light System for Trans-PRK

🟢 Green Light (Ideal Conditions):

  • Myopia (short-sightedness): Up to approx. -6.0 diopters (higher values increase haze risk).
  • Extremely thin corneas (where Femto-LASIK or SmartSight are no longer possible).
  • Professional athletes, martial artists (MMA, boxing), and emergency personnel (police/WEGA).
  • People with an absolute phobia of an “incision” in the eye.

🟡 Yellow Light (Precise Medical Clarification Needed):

  • Astigmatism over 3 diopters (healing at the surface is often less predictable than in depth).
  • Hyperopia (long-sightedness): Trans-PRK for plus values is often associated with a long and difficult healing phase. Here we preferably recommend Femto-LASIK.

🔴 Red light (Not suitable):

  • Very high myopia over -8 diopters. Here, the implantable contact lens (EVO ICL) is often the perfect and safe alternative.
  • Keratoconus (pathological corneal weakness) without accompanying crosslinking.
  • Severe rheumatic or autoimmune diseases (healing disorders).

“Trans-PRK is a fascinating procedure from a medical perspective. I always tell my patients: We artificially put your eye into the state of a harmless abrasion. That’s uncomfortable for a few days. But the biological reward is immense. Since we leave the static architecture of the cornea untouched, your eye is just as resistant after healing as that of a person who has never been operated on. Those who make this short-term sacrifice receive the ultimate, lifelong gold standard for safety.”
– Dr. med. univ. Victor Derhartunian, FEBO
