What is TransPRK?

Transepithelial PhotoRefractive Keratectomy (or TransPRK for short), represents a very recent iteration of laser refractive surgery. The evolution of this form of surgery started with PRK, which was soon overtaken by LASIK, or laser in situ keratomileusis. The reasons for this takeover were that LASIK offered much faster recovery of vision and eye comfort than PRK, where recovery was delayed by the need for the surface cells of the cornea to heal. There is also less risk of corneal scarring and refractive regression with LASIK compared with PRK. Correct your vision without the need to cut a cornea flap with no touch, no blade TransPRK However, LASIK may not be suitable for everyone. Hence, TransPRK has been introduced as a form of laser surface ablation to cater for the group of individuals who are not suitable for LASIK. TransPRK is a non-invasive, no blade surface-based procedure; a safer procedure that is suitable for almost everyone, especially if you have been rejected for LASIK. TransPRK may be a second chance for patients with thin cornea and for patients who have had complications from LASIK and Epi-LASIK.

How perform the TransPRK operation?

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. The Sydney Eye Clinic is able to provide the necessary medication to minimise any discomfort during your recovery.

After TransPRK

In PRK with older techniques required improved recovery time for corneal surface cells. But with the advent of technology and new techniques, the TransPRK operation was introduced, which could almost certainly overcome the shortcomings and limitations of older methods. In PRK, the patient experienced a lot of pain and burning after surgery and during his recovery. The patient also had a blurred vision for a long time. But nowadays, immediately after the laser treatment, your vision will already be clearer than normal. However, your vision will be slightly blur over the next 3 to 4 days because the surface cells (Epithelium) will take some time to regenerate over the corneal surface which is not as smooth as before. A transparent thin contact lens is placed over the eye immediately after surgery to protect the cornea and speed up the recovery of these epithelial cells. Your vision will continue to improve in the following week and you should be able to see tremendous improvement by the end of this period.
