How TransPRK is Done?

TransPRK is a laser vision correction that is safe and minimally-invasive as it is surface-based. Here’s a simple step-by-step explanation of how TransPRK procedure is done:



Step 1

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 1050RS 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.

TransPRK surgery process. Firstly, a local anaesthetic in a form of eyedrops is used. Secondly, the removal of epithelium layer using excimer laser. Thirdly, reshaping the cornea structure by using the same excimer laser. Fourthly, temporary placement of bandage contact lens to protect the eye while the epithelium cells are healing
