What is TransPRK?

Transepithelial PhotoRefractive Keratectomy (TransPRK) is the most recent technique of laser refractive surgery. TransPRK may be known to some as No Touch LASIK, No Touch Laser Epi-LASIK, SmartSurface PRK or Transepithelial Surface Ablation (TESA).

The Procedures

Numbing eye drops

TransPRK surgery is painless - numbing eye drops are applied before the procedure.

Removal of surface cells

The laser removes the outmost layer of cells. No surgical equipment or suction rings touch the eyes.

Reshaping of cornea

The laser then goes on to seamlessly reshape the corneal curvature - vision is now corrected!

Bandage contact lens

A bandage contact lens is placed over the eye to protect it during recovery; it will be removed after 5 days.

Advantages of TransPRK

Touch-free procedure

No risk of flap-related complication

Quick surgery

No blades or incisions

Tissue-saving procedure

Our Equipment

Corneal Topography Machine

A corneal topography machine is used to accurately scan the cornea curvature and thickness to detect corneal disorders and to determine if your eyes are suitable for TransPRK.

Excimer Laser

An excimer laser is used for corneal stroma ablation of the to treat the refraction or ‘power’. Both the SCHWIND AMARIS and Bausch & Lomb TENEO laser machine can perform the no-touch TransPRK in a single step.

During FemtoLASIK, a femtosecond laser (VISUMAX 800) is used to create a flap on the cornea before the stromal ablation by excimer laser.

Yes, laser vision correction such as TransPRK, LASIK and SMILE pro considered safe and effective for most people. These procedures have been widely performed for over two decades, boasting a high success rate, with the majority of patients achieving 20/20 vision or better. Serious complications are rare and most side effects like dry eyes are usually temporary with quick recovery times.
Medical insurance cannot be used to claim for laser vision correction as the procedure falls under the category of an elective or cosmetic procedure.

Yes, you should stop wearing your contact lenses before the assessment.
