Laser Eye Surgery Risks and How to Minimise Them

Understanding Laser Eye Surgery

Laser eye surgery is a widely used procedure designed to correct refractive errors, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. By reshaping the cornea with advanced laser technology, patients can significantly reduce or even eliminate the need for glasses or contact lenses.

Common techniques include LASIK (Laser-Assisted In Situ Keratomileusis), PRK (Photorefractive Keratectomy), SMILE (Small Incision Lenticule Extraction), and Wavefront-guided LASIK. Each technique has unique advantages and potential risks, which must be carefully considered.

While laser eye surgery is generally safe and effective, understanding the risks and how to minimise them is critical for a successful outcome.

Preparing for Your Procedure

Proper preparation is key to reducing complications and ensuring a smooth recovery.

1. Comprehensive Eye Examination

  • Conducted by a qualified ophthalmologist, including corneal mapping, vision tests, and pupil measurements.
  • Identifies conditions like thin corneas or severe dry eyes that may increase risks.

2. Discontinuing Contact Lenses

  • Soft lenses: stop wearing 1–2 weeks prior.
  • Rigid lenses: longer discontinuation required.
  • Ensures accurate corneal measurements for precision laser treatment.

3. Lifestyle and Health Review

  • Inform your ophthalmologist about medications, chronic illnesses, and prior eye conditions.
  • Avoid eye makeup or lotions on the day of surgery.

4. Scheduling and Support

  • Arrange transportation; you won’t be able to drive immediately after surgery.
  • Plan downtime, especially if undergoing PRK, which may have a slower visual recovery.

What Happens During Laser Eye Surgery

Laser eye surgery is fast, precise, and generally painless.

Step-by-Step Overview

  1. Eye Preparation
    • Numbing drops applied to minimise discomfort.
    • Eyelid holders keep eyes open during the procedure.
  2. Technique-Specific Procedure
    • LASIK: Flap creation, corneal reshaping, flap repositioning.
    • PRK: Removal of corneal surface layer, laser reshaping, natural regeneration.
    • SMILE: Small incision, removal of lens-shaped tissue, minimal disruption.
    • Wavefront-guided LASIK: Customized treatment based on detailed corneal topography.
  3. Duration
    • Typically 15–30 minutes for both eyes.

Tip: Wear sunglasses after surgery to reduce light sensitivity.

Recovery and Aftercare

Proper aftercare is essential to minimise risks and ensure effective healing.

Immediate Post-Surgery

  • Mild burning, tearing, or blurred vision is common.
  • Follow eye drop schedules and avoid rubbing your eyes.

First Week

Laser Eye Surgery lens
  • Limit screen time and exposure to smoke or dust.
  • Attend follow-up appointments to monitor healing.

First Month

  • Recovery depends on technique; LASIK and SMILE generally recover faster than PRK.
  • Avoid swimming, hot tubs, or eye makeup to prevent infection.

Recovery Tips

  • Use lubricating drops as prescribed.
  • Wear sunglasses outdoors.
  • Rest adequately and follow all post-operative instructions from your ophthalmologist.

Risks, Benefits, and Long-Term Results

Common Risks

  • Dry eyes and temporary glare or halos.
  • Under-correction or over-correction, sometimes requiring enhancement.
  • Rare complications include infection or flap-related issues in LASIK.

How to Minimise Risks

  1. Choose a qualified ophthalmologist with experience in your chosen technique.
  2. Follow all pre- and post-operative instructions carefully.
  3. Avoid risky activities during early recovery, such as swimming or rubbing eyes.
  4. Attend all follow-up appointments for monitoring and early intervention if needed.

Benefits

  • Reduced dependence on glasses or contacts.
  • Quick, precise, and generally painless procedure.
  • Long-lasting visual improvement for most patients.

Long-Term Results

  • Most patients achieve 20/25 vision or better.
  • Vision may change naturally with age, requiring occasional adjustments.

(FAQ)

Is laser eye surgery safe for everyone?
Candidates must have stable vision, healthy corneas, and no severe eye conditions.

How long is recovery?

  • LASIK/SMILE: 1–2 days for basic recovery.
  • PRK: 3–5 days or longer for full visual clarity.

What are the common side effects?
Temporary dry eyes, glare, halos, or slight under/over-correction may occur.

How much does it cost in Australia?
Costs generally range from $2,000–$4,000 per eye, depending on the clinic and procedure.

Can complications be treated?
Most complications are rare and manageable if caught early; follow-up care is essential.
