For individuals seeking freedom from glasses or contact lenses, laser eye surgery offers a transformative solution. LASIK (Laser-Assisted In Situ Keratomileusis) and PRK (Photorefractive Keratectomy) are two of the most commonly performed types of laser eye surgery, each with its unique advantages and considerations. In this article, we will compare LASIK and PRK, exploring their differences in procedure, recovery, candidacy criteria, potential risks, and benefits to help individuals make informed decisions about vision correction options [1].

LASIK: LASIK is a widely performed refractive surgery that aims to correct refractive errors such as myopia, hyperopia, and astigmatism. During LASIK, a thin flap is created on the surface of the cornea using a microkeratome or femtosecond laser. The flap is then lifted, and an excimer laser is used to reshape the underlying corneal tissue to correct the refractive error. Finally, the flap is repositioned, allowing for rapid healing and visual recovery [2].

PRK: PRK is an alternative to LASIK, particularly for individuals with thin or irregular corneas. In PRK, the outer layer of the cornea (epithelium) is removed entirely, exposing the underlying stroma. The excimer laser is then used to reshape the corneal stroma to correct the refractive error. As there is no flap creation in PRK, the recovery process is longer compared to LASIK [3].

Flap Creation: LASIK involves the creation of a corneal flap, which is lifted to access the underlying corneal tissue for reshaping. PRK does not involve flap creation; instead, the outer layer of the cornea is removed entirely to expose the stroma for laser treatment. Recovery Time: LASIK typically has a faster visual recovery compared to PRK, as the corneal flap created in LASIK acts as a natural bandage, promoting faster healing. PRK involves the regrowth of the epithelial layer, resulting in a longer recovery time and temporary visual fluctuations during the healing process [4].

Corneal Thickness: LASIK requires sufficient corneal thickness to create a flap and perform the laser ablation. PRK may be preferable for individuals with thinner corneas or irregular corneal anatomy. Occupational Considerations: Individuals in professions with a higher risk of eye trauma or those engaged in contact sports may be better suited for PRK, as it eliminates the risk of flap dislocation associated with LASIK. Refractive Stability: Both LASIK and PRK require stable refractive errors for at least one year before surgery to ensure optimal outcomes [5,6].

Dry Eye Syndrome: Both LASIK and PRK can cause temporary dryness of the eyes following surgery, though it tends to resolve over time with appropriate treatment. PRK may have a slightly higher risk of persistent dry eye compared to LASIK due to the longer recovery time. Corneal Haze: PRK carries a higher risk of corneal haze formation during the healing process, particularly in individuals with higher degrees of refractive error. Flap Complications: LASIK is associated with flap-related complications such as flap dislocation, flap wrinkles, or epithelial ingrowth, though these are rare [7].

Improved Vision: Both LASIK and PRK offer significant improvements in vision clarity and reduce dependence on glasses or contact lenses. Long-Term Results: LASIK and PRK provide long-term vision correction, with the majority of patients maintaining improved vision for years following surgery. Enhanced Quality of Life: Freedom from glasses or contact lenses can lead to an improved quality of life, greater convenience in daily activities, and enhanced self-confidence [8,9].

Medication Regimen: Patients undergoing LASIK or PRK are typically prescribed antibiotic and anti-inflammatory eye drops to prevent infection and reduce inflammation following surgery. Follow-Up Visits: Scheduled follow-up visits with the surgeon are essential to monitor healing progress, assess visual acuity, and address any concerns or complications. Patient Satisfaction and Success Rates: Both LASIK and PRK have high patient satisfaction rates, with the majority of patients achieving their desired visual outcomes. Success rates for both procedures vary depending on factors such as refractive error, corneal thickness, and surgeon experience [10].


LASIK and PRK are both effective options for correcting refractive errors and achieving clearer vision without the need for glasses or contact lenses. While LASIK offers faster visual recovery and a shorter healing time, PRK may be preferable for individuals with thinner corneas or those at higher risk of flap-related complications. Ultimately, the decision between LASIK and PRK should be made in consultation with an experienced eye care professional, taking into account individual preferences, lifestyle factors, and medical considerations. With careful consideration and thorough evaluation, laser eye surgery can provide life-changing benefits and a new perspective on the world
