TransPRK Surgery Steps

TransPRK is an advanced vision correction procedure from epiLASIK. It is a safe, non-invasive and surface-based treatment method which does not require the eye surgeon to cut a corneal flap. With new advances in technology today, TransPRK can eliminate some of the risks in the standard LASIK (cut, flap and zap) procedure such as flap-related medical complications.

How does TransPRK work?

TransPRK is a new one-step, incision-free procedure. Using the one laser, the epithelium (the regenerative outer surface of the eye) is gently removed and the cornea precisely reshaped. Our state-of-the-art laser concentrates a ‘cool’ ultraviolet light beam and high-energy pulses on the cornea. The laser removes a microscopic amount of stromal tissue, calculated on the pre-operative analysis and determination of the power of your eye. The procedure enables the contour of the cornea to be reshaped in less than one minute.

After the cornea of the eye has been re-contoured, clear contact lenses are used to reduce discomfort during the healing of the epithelium and provide protection for the eye. The contact lenses are usually removed 3-4 days after surgery at your first post-operative assessment. Your Ophthalmologist or Surgeon is able to provide the necessary medication to minimise any discomfort during your recovery.

TransPRK Steps

TransPRK is fast, simple and safe. In TransPRK, there are no surgical devices touching the eye at all, making it a truly all laser, one-step, no touch, non-invasive and safe procedure. We use the high-tech, advanced excimer laser.

Step1

Patient lies down and simply looks ahead at a blinking fixation green light. No suction ring nor surgical instrument touches the eye.

Step 2

Epithelium cells are removed with the Schwind Amaris laser

Step 3

Laser goes on to reshape the cornea curvature to correct the refractive power in one step seamlessly.

Step 4

A transparent, high-oxygen permeability content soft contact lens is then placed over the cornea to act as an artificial cornea flap to protect the treated surface while the epithelium cells regenerate.

Step 5

The epithelium cells then take 3 to 5 days to regenerate and heal. It is important to use the eye drops medications prescribed and stay away from strong sunlight for good healing. The high-oxygen permeability contact lens is removed after 5 days.
