LASIK vs. PRK: Choosing the Best Vision Correction Surgery

Refractive eye surgeries like LASIK (Laser-Assisted in Situ Keratomileusis) and PRK (Photorefractive Keratectomy) have transformed the way people correct vision problems, eliminating the need for glasses or contact lenses. Both procedures are highly effective in treating myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, but they differ in technique, recovery time, and patient suitability.

This comprehensive guide compares LASIK vs PRK, helping you decide which vision correction surgery aligns with your needs.

What is the PRK Procedure?

PRK was the first laser vision correction procedure approved by the FDA in 1995. Although it requires a longer recovery period compared to LASIK, it offers advantages such as better long-term corneal stability and reduced risk of flap complications. Since PRK removes the entire outer layer (epithelium), it takes 3–5 days for the new epithelial cells to regenerate, leading to discomfort and blurry vision initially. However, PRK remains an excellent alternative for individuals with corneal irregularities or those who engage in high-impact sports.

A study published in the Journal of Cataract and Refractive Surgery found that PRK and LASIK have similar long-term visual outcomes, with over 90% of PRK patients achieving 20/20 vision. The healing process, however, varies significantly, making PRK more suitable for individuals willing to endure a longer recovery period for added safety.

PRK is the predecessor of LASIK and follows a different approach:

  1. Removal of the Epithelium – The outer corneal layer is removed entirely.
  2. Reshaping the Cornea – An excimer laser reshapes the cornea to correct vision.
  3. Healing Process – A bandage contact lens is placed over the eye for protection during healing.

Since PRK does not involve a flap, it is suitable for people with thin corneas.

Pros of PRK Surgery

  • No Flap Complications: Ideal for those with thin or irregular corneas
  • Long-Term Stability: Less risk of corneal weakening. 
  • Suitable for Athletes and Military Personnel: No risk of flap dislocation. 
  • Effective for High Prescriptions: Works well for high myopia.

Side Effects of PRK Surgery

  • Longer Healing Time (up to 1–2 weeks for vision stabilization)
  • More Discomfort due to epithelium removal
  • Light Sensitivity lasting a few weeks

Risks of PRK Surgery

  • Haze Formation: Slight risk of corneal scarring.
  • Longer Recovery Period: Patients require 3–6 months for full visual improvement.

Cost of PRK Surgery

PRK is slightly cheaper than LASIK:

  • USA: $1,500 – $3,000 per eye
  • UK: £1,200 – £2,200 per eye

What is the LASIK Procedure?

Unlike traditional corrective measures like glasses and contact lenses, LASIK provides a permanent solution by directly altering the corneal shape. The entire procedure typically takes less than 15 minutes per eye, and most patients experience improved vision within a few hours post-surgery. The corneal flap created during LASIK ensures faster healing and reduced pain compared to other laser surgeries.

Over 700,000 LASIK surgeries are performed annually in the U.S. alone, with a success rate exceeding 96%. This procedure is especially effective for individuals who struggle with daily visual aids and seek long-term convenience. However, a comprehensive eye examination is necessary to determine eligibility, as factors like corneal thickness, eye dryness, and overall eye health play a crucial role in candidacy.


LASIK is the most popular refractive surgery worldwide. It involves the following steps:

  1. Creating a Corneal Flap – A femtosecond laser or microkeratome creates a thin flap in the cornea.
  2. Reshaping the Cornea – An excimer laser reshapes the corneal tissue to correct vision.
  3. Flap Repositioning – The corneal flap is repositioned, which adheres naturally without stitches.

LASIK is widely chosen due to its quick recovery and minimal discomfort.

Pros of LASIK Surgery

  • Quick Procedure: The surgery takes about 10–15 minutes per eye. 
  • Fast Recovery: Most patients achieve clear vision within 24 hours
  • Minimal Pain: The corneal flap reduces post-op discomfort. 
  • Long-Lasting Results: Vision correction remains stable for years. 
  • High Success Rate: Over 90% of LASIK patients achieve 20/20 vision or better.

Side Effects of LASIK Surgery

  • Dry Eyes (experienced by 30–50% of patients in the first few months)
  • Night Glare and Halos (common in 20% of cases but usually temporary)
  • Flap Complications (rare but possible)

Risks of LASIK Surgery

  • Corneal Ectasia: A rare condition where the cornea bulges outward.
  • Under- or Overcorrection: May require enhancement surgery.
  • Flap Displacement: Can occur with trauma to the eye post-surgery.

Cost of LASIK Surgery

The cost of LASIK varies depending on location and technology used:

  • USA: $2,000 – $3,500 per eye
  • UK: £1,500 – £2,500 per eye

Factors to Consider for Both

1. Suitability

LASIK is best suited for individuals with adequate corneal thickness, while PRK is recommended for those with thin or irregular corneas. A comprehensive eye evaluation is necessary to determine which procedure aligns with a patient’s eye health.

2. Healing Time

LASIK patients typically experience clear vision within 24–48 hours, whereas PRK recovery takes longer, often 1–2 weeks for functional vision and up to 3–6 months for full clarity.

3. Lifestyle Considerations

People engaged in high-impact sports or professions where eye injuries are common may find PRK more suitable, as it eliminates the risk of flap displacement. LASIK, however, is ideal for those seeking a quick return to normal activities.

4. Long-Term Results

Both LASIK and PRK provide similar long-term vision correction outcomes, with stable results over time. PRK may have an edge in cases where corneal stability is a concern, particularly for individuals with pre-existing corneal conditions.

Who is Ideal for LASIK or PRK?

LASIK is ideal for:

LASIK is well-suited for individuals with a normal corneal thickness who prioritize a quick recovery time and minimal post-operative discomfort. It is an excellent option for those with mild to moderate prescriptions and individuals who prefer a procedure with fewer restrictions in the days following surgery. Patients who require immediate visual clarity for work or daily activities often find LASIK to be the most convenient choice.

PRK is ideal for:

PRK is often recommended for individuals with thin corneas, as it eliminates the risk of flap complications associated with LASIK. This procedure is particularly beneficial for athletes, military personnel, and individuals in high-impact professions, where physical activity may put them at risk of flap displacement. PRK also tends to be preferred for patients with severe myopia or irregular corneas, ensuring a more stable and long-term vision correction outcome.

Which Is Better, PRK or LASIK?

There is no one-size-fits-all answer. Both procedures achieve excellent visual outcomes, but the choice depends on individual factors.

  • If you want a quick recovery and have a suitable corneal thickness, LASIK is the best choice.
  • If you have thin corneas or are involved in contact sports, PRK is a better option.

LASIK = Faster recovery, minimal pain, but has flap-related risks. 

PRK = Longer healing, more discomfort, but safer for thin corneas.

Conclusion

Both LASIK and PRK offer permanent vision correction with high success rates. Before making a decision, consult an experienced ophthalmologist to determine which surgery best suits your eye health and lifestyle.

With advances in laser technology, both procedures remain highly effective choices for those looking to eliminate glasses and contacts forever.
