What is PRK (Photorefractive Keratectomy) ?

.

Why do you need PRK ?

PRK is indicated for:

  • Refractive errors:
    • Myopia: Nearsightedness (-1 to -8 diopters, depending on corneal thickness).
    • Hyperopia: Farsightedness (+1 to +4 diopters).
    • Astigmatism: Irregular corneal shape (up to 4 diopters).
  • Specific candidates:
    • Thin corneas (<480–500 microns): Unsuitable for LASIK flap creation.
    • Active lifestyles: High risk of flap trauma (e.g., athletes, military personnel).
    • Stable vision: Prescription unchanged for at least 1 year; typically for ages 18–40.
  • Healthy eyes:
    • No corneal diseases (e.g., keratoconus), severe dry eyes, or contraindications (e.g., uncontrolled glaucoma).

The procedure aims to improve vision to 6/6 or 6/9 (normal or near-normal) by removing the corneal epithelium and reshaping the underlying stroma with a laser, reducing dependency on glasses or contact lenses.

PRK Procedure

  • Before Surgery Evaluation:
    • Assessment:
      • Corneal topography: Maps corneal shape and thickness.
      • Refraction: Confirms prescription (e.g., myopia, astigmatism).
      • Pachymetry: Measures corneal thickness (must allow safe ablation).
      • Slit-lamp exam: Checks for dry eyes, corneal scars, or abnormalities.
      • Pupil size: Large pupils (>6 mm) may increase risk of glare/halos.
      • Blood tests: Not typically needed unless systemic conditions (e.g., diabetes) suspected.
    • Medications: Stop contact lenses 1–2 weeks prior (to avoid corneal molding); antibiotic eye drops (e.g., moxifloxacin) 1 day pre-surgery.
    • Consent: Risks, including delayed healing, are explained.
  • Surgical Techniques:
    • PRK:
      • Performed under topical anesthesia (e.g., proparacaine drops), lasting 10–15 minutes per eye.
      • The corneal epithelium (outer layer, 50 microns) is removed using a diluted alcohol solution (20% ethanol) or a rotating brush.
      • An excimer laser reshapes the corneal stroma by removing precise amounts of tissue (e.g., flattens for myopia, steepens for hyperopia).
      • Mitomycin-C (MMC, 0.02%) may be applied for 20–60 seconds in high corrections to reduce haze risk.
      • A bandage contact lens is placed to protect the cornea during epithelial healing (removed after 3–5 days).
    • Variations:
      • TransPRK: Laser removes epithelium and reshapes stroma in one step; no alcohol used.
      • LASEK: Epithelium is loosened with alcohol and flipped back (like a flap) before laser treatment; less common.
    • Intraoperative Tools:
      • Excimer laser: Reshapes cornea.
      • Bandage contact lens: Protects cornea post-procedure.
      • Speculum: Keeps eyelids open.
  • After Surgery:
    • Observation: 30–60 minutes; same-day discharge.
    • Eye care: Antibiotic drops (e.g., moxifloxacin) and steroid drops (e.g., prednisolone) for 1–2 weeks; artificial tears for dryness.
    • Pain management: Moderate pain for 2–3 days (due to epithelial removal); managed with oral analgesics (e.g., ibuprofen) and cycloplegic drops (e.g., cyclopentolate).
    • Instructions: Avoid rubbing eyes, swimming, or makeup for 2 weeks; wear sunglasses for UV protection.

Recovery After PRK

  1. Immediate Recovery: Same-day discharge; vision blurry for 3–5 days due to epithelial healing.
  2. Post-Surgery Care:
    • Pain: Moderate discomfort for 2–3 days (due to epithelial removal); managed with analgesics and cycloplegic drops.
    • Vision: Improves gradually; functional vision in 1–2 weeks; stabilizes in 1–3 months; 90–95% achieve 6/6 or 6/9 vision.
    • Eye care: Antibiotic/steroid drops for 1–2 weeks; artificial tears for 1–3 months (dryness common); bandage lens removed after 3–5 days.
    • Activity: Avoid rubbing eyes, swimming, or dusty environments for 2 weeks; normal activities (e.g., reading) in 3–5 days; driving in 1–2 weeks (if vision meets legal standards).
    • Light sensitivity: Common for 1–2 weeks; sunglasses help.
  3. Follow-Up:
    • Visits at 1 day, 1 week (bandage lens removal), 1 month, then 3–6 months to monitor vision and healing.
    • Refraction: Confirms final vision at 1–3 months.

Most resume normal activities in 1–2 weeks; full recovery takes 1–3 months. Success rate: 90–95% achieve target vision; 5–10% may need enhancement (repeat PRK or LASIK) for residual refractive error.

Risks and Complications

  • Surgical Risks:
    • Infection (1–2%): Corneal infection (keratitis); treated with antibiotics, may lead to scarring.
    • Corneal haze (5–10%): Temporary cloudiness, esp. with high corrections; usually resolves in 6–12 months; MMC reduces risk.
    • Under/Overcorrection (5–10%): Residual refractive error; may need glasses or enhancement.
  • Post-Surgery:
    • Dry eyes (10–20%): Common for 1–3 months; managed with artificial tears; severe cases rare.
    • Glare/Halos (5–10%): Night vision issues, esp. with large pupils; usually improve in 3–6 months.
    • Delayed epithelial healing (2–5%): Prolongs discomfort; may increase infection risk.
    • Corneal scarring (1–3%): Permanent haze; may affect vision, rare with MMC.
  • Long-Term:
    • Regression (2–5%): Vision changes over years; may need enhancement.
    • Corneal ectasia (<0.1%): Rare; corneal bulging if undiagnosed keratoconus; may need cross-linking or transplant.

Report severe pain, sudden vision loss, or redness promptly. 

Frequently Asked Questions (FAQs)

Who is a candidate for PRK?

Age 18–40, stable vision, refractive errors within treatable range, thin corneas, or high risk of flap trauma (unlike LASIK); no severe dry eyes or keratoconus.

Can I avoid PRK?

Yes, alternatives include glasses, contact lenses, LASIK, SMILE, or IOL implantation for high refractive errors.

Is PRK painful?

Moderate pain for 2–3 days (due to epithelial removal); managed with medication; less discomfort after epithelial healing.

How soon can I resume activities?

Light activities in 3–5 days; normal routines in 1–2 weeks; full recovery in 1–3 months.

Is PRK covered by insurance in India?

Rarely, as it’s considered cosmetic; confirm with your provider.

Signs of complications?

Severe pain, sudden vision loss, or increased redness.

How does PRK compare to LASIK?

PRK: No flap, longer recovery, more initial discomfort, better for thin corneas; LASIK: Faster recovery, less discomfort, but flap-related risks.

Lifestyle changes post-surgery?

Avoid rubbing eyes for 2 weeks, use prescribed drops, wear sunglasses for UV protection, avoid swimming for 2 weeks, and attend follow-ups.
