Transepithelial PRK is a no touch, one step laser only treatment for shortsightedness, longsightedness, and astigmatism. Compared to PRK, many patients find there is a speedier recovery. Compared to LASIK, Transepithelial PRK does not require an additional procedure to create a flap in order to expose the layer where laser treatment is applied. Using anaesthetic drops, your Doctor will numb your eyes. Rather than create a flap in the cornea, Transepithelial PRK uses a laser to remove a thin layer of cells which naturally grow back after surgery. Transepithelial PRK is therefore preferred in patients with a thinner cornea. You will be asked to look at a blurry light. Once you're ready, the laser treatment is applied. Advanced computer calculations determine the number of laser pulses from measurements taken before surgery. Once complete, drops and a temporary contact lens are applied to allow the eye to heal.
