No-Touch PRK (Photorefractive Keratectomy) is a modern laser eye treatment performed without any physical contact with the eye surface. The method is based on the complete vaporization of the surface layer of the cornea using laser technology. Since no flap is created, it is a safe option, especially for individuals with thin corneas.
No-Touch PRK is also known as TransPRK or surface laser treatment. It is used to correct refractive errors such as myopia, astigmatism, and mild hyperopia. Thanks to its no-contact nature, the recovery process is controlled and safe.

How Is No-Touch PRK Laser Eye Treatment Performed?
-
Preparation: Local anesthesia is provided with eye drops; patient comfort is a priority.
-
Epithelium Removal: The epithelial tissue on the cornea is gently vaporized with a laser. No physical contact is made with the eye.
-
Corneal Reshaping: Using the same laser system, the cornea is reshaped to correct refractive errors.
-
Protective Lens Application: A transparent, soft contact lens is placed on the eye to support healing.
-
Medication and Instructions: Antibiotic and moisturizing eye drops are prescribed, and usage instructions are provided.
-
Post-Procedure Check: The eyes are examined, and the patient is discharged with a prescription and care guidelines.
The entire treatment takes about 15 minutes. The clinic visit may last 2 to 2.5 hours.
Post-Treatment Care After No-Touch PRK
-
Burning, stinging, and tearing may occur in the first few days—this is temporary.
-
Vision may be blurry at first and gradually become clearer over a few weeks.
-
Avoid rubbing your eyes for at least 2 weeks.
-
Wear sunglasses for the first 2 weeks.
-
Avoid makeup for 3 days; apply with care afterward.
-
Stay away from dusty or smoky environments for 2 weeks.
-
Avoid sauna, tanning, sunbathing, and swimming during the first 2 weeks.
-
Use protective nighttime goggles during the first few days.
-
Do not exercise for the first 3 days and avoid sweat contact with the eyes.
When Will Results Be Noticeable?
Recovery after No-Touch PRK may vary by individual. Although vision usually begins to improve within the first few days, the final results typically settle between 1–3 months. Temporary glare, light sensitivity, or dryness may occur but gradually subside.
Most patients return to their daily routines within 4–5 days. Follow-up sessions are scheduled if needed. The need for additional treatment is very low.
Tips for Using Eye Drops
-
Apply drops with clean hands and your head tilted back.
-
Do not let the bottle tip touch your eye.
-
Keep your eyes closed for a few seconds after applying drops.
-
Use as prescribed in terms of frequency and duration.
-
If wearing a bandage lens, follow the lens usage guidelines carefully when applying drops.
