PRK (No Touch Laser) Surgery
PRK Laser Eye Surgery: Precision and Safety in Vision Correction
Photorefractive Keratectomy (PRK) is a time-tested refractive surgery designed to correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. As the predecessor to LASIK, PRK remains a primary choice for many patients, offering exceptional long-term visual outcomes.
What Makes PRK Unique?
Unlike LASIK, which involves creating a thin flap on the cornea, PRK works by gently removing the outermost layer of the cornea (the epithelium). The surgeon then uses a specialized excimer laser to reshape the underlying corneal tissue.
Because no flap is created, PRK is often the ideal solution for:
Patients with thinner-than-average corneas.
Individuals with active lifestyles or professions (such as athletes or military personnel) where eye trauma is a risk.
Those with specific corneal surface irregularities.
The Procedure: Step-by-Step
Preparation: Numbing drops are applied to ensure the patient feels no pain.
Surface Removal: The epithelium is carefully removed to expose the corneal bed.
Laser Reshaping: A computer-controlled excimer laser applies pulses of light to reshape the cornea in seconds, correcting the refractive error.
Protection: A clear, "bandage" contact lens is placed over the eye to protect it while the epithelium regenerates naturally.
The Recovery Timeline
The recovery process for PRK is slightly longer than LASIK because the surface layer of the eye needs time to grow back.
The First 3–5 Days: Some discomfort, light sensitivity, and tearing are normal as the epithelium heals.
The First Week: The bandage contact lens is typically removed by your specialist.
Long-Term Results: While initial vision may be blurry, patients usually achieve peak visual clarity within 3 to 6 weeks, with results that are often identical to or even more stable than other laser methods.
