What is Safe Sight TransPRK?

Safe Sight 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, Safe Sight TransPRK can eliminate some of the risks in the standard LASIK (cut, flap and zap) procedure such as flap-related medical complications.

How does Safe Sight TransPRK work?

Safe Sight TransPRK at Clearvision is fast, simple and safe. In Safe Sight 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 Schwind Amaris 1050RS excimer laser. The Schwind Amaris 1050RS laser is the world’s fastest laser machine, equipped with a zero latency eye tracker. It is also the only laser technology with the ability to track all 7-dimensionals of eye movements, resulting in fast and accurate treatment.




First, the Schwind Amaris laser gently ablates the surface epithelium cells. (Patient looks ahead at a green blinking fixation light)


Step 2

The Schwind Amaris laser goes on to reshape the cornea curvature to correct the patient’s myopia in one seamless step.

(Patient simply continues to fixate gaze on green blinking light)


Step 3

Cornea epithelium regenerates itself in 3 – 5 days with the help of the high-oxygen content soft lens which acts as an artificial flap.

(Patient wears the contact lenses for about 5 days. Contact lenses are then removed by the eye surgeon during the follow up review)

Corneal Cross-Linking (CXL)

CXL is an additional treatment to the Safe Sight TransPRK procedure that helps to strengthen the cornea through corneal collagen cross-linking. It is a relatively fast procedure, taking an additional two minutes of time.

Using the Avedro KXL system, CXL can help to minimize the weakening effects that comes with the laser sculpting of the cornea in refractive surgeries. As laser sculpting with the excimer tissue involves tissue ablation, corneas will naturally become thinner after refractive surgeries. The higher your spectacle power, the more corneal tissue is required in laser sculpting.

CXL is especially suitable for patients with:

  1. Thin or weak cornea
  2. Very high spectacle power
