About No Touch Laser
Excimer laser is a high-precision technology that permanently corrects refractive errors by reshaping the corneal surface. No Touch Laser (transepithelial PRK) offers a no-contact approach in which laser energy removes the corneal epithelium and reshapes the stroma in a single step.
Because no blade or mechanical instrument touches the eye surface, the risk of infection is reduced. This makes No‑Touch Laser a suitable option for patients with thin corneas or steep corneal anatomy.
What is No Touch Laser?
No‑Touch Laser is a surface ablation technique performed entirely with the laser — no alcohol solution or mechanical scraping is needed to remove the epithelium. The patient fixates on a light target while the laser pulses reshape the epithelium and stroma in sequence.
Contactless treatment
Because no instrument touches the surface, trauma to delicate tissues is minimized.
Single‑step procedure
Epithelial removal and refractive correction are completed in the same session, reducing overall procedure time.
Who No Touch Laser For Is suitable?
Candidate Profili
- Patients with myopia, hyperopia or astigmatism within the treatment range for surface laser
- Individuals with corneas too thin for LASIK but suitable for a surface laser
- Patients who have had previous cataract surgery or who are at increased risk of retinal tears
Personalized considerations
In eyes with a steep cornea, surface laser may be preferred as it does not require a corneal flap. It does not cause an increase in intraocular pressure in eyes previously treated for retinal disease.
Specialist assessment
Topography, pachymetry and tear tests are used to determine safe treatment parameters.
No Touch Laser How Is performed?
The procedure is performed under topical anesthesia; most patients feel little or no pain. The laser head is positioned over the eye and the patient focuses on a green fixation light. Because there is no physical contact, sterilization is simplified and early healing is facilitated.
Preparation
Topical anesthetic drops are applied, the eyelids are gently opened and the patient is asked to fixate on the target light.
Epithelial removal
The excimer laser gently ablates the epithelial layer, preparing the corneal surface in a single step.
Shaping & protection
The refractive error is corrected and a bandage contact lens is placed to protect the cornea during early healing.
Smooth corneal surface and clear vision
Which laser method is suitable for you?
We compare No‑Touch Laser, PRK and LASIK based on corneal thickness, lifestyle and occupational needs to find the right option for you.
Contactless comfort
Because the corneal surface is not touched, the risks of infection and mechanical trauma are reduced.
- Ideal for sensitive corneas
- Blade‑free and suture‑free
Advanced safety
Modern eye‑tracking systems pause the laser if patient movement is detected, improving safety.
- Both eyes often treated in ~60 seconds
- Personalized ablation profiles
Broad applicability
No‑Touch Laser can be safely considered for patients with thin corneas or those who have had prior retinal treatment.
- Post‑cataract cases
- Options for high astigmatism
No Touch Laser After Recovery
A protective bandage contact lens is placed after the procedure; the epithelium typically re‑forms within 3–4 days. Stinging, tearing and light sensitivity are common in the first days and usually resolve as healing progresses.
- Use lubricating artificial tears and pain relievers as prescribed.
- To prevent infection, use antibiotic eye drops exactly as directed.
- Protect your eyes from UV light with sunglasses and avoid rubbing your eyes.
- Avoid swimming, using eye makeup and strenuous exercise during the first week.
- The bandage lens is removed during follow‑up appointments and vision checks are performed.
Vision typically improves within 1–2 weeks; complete stabilization may take several months.
