Photorefractive Keratectomy (PRK) is the original excimer eye laser technique. Dr David Kent was the first surgeon to perform PRK in the South Island in 1997.
PRK is recommended as an alternative to LASIK or SMILE eye laser for people with a thin cornea; a cornea that does not have a symmetrical shape; or anyone whose lifestyle places them at high risk of an eye injury.
Advanced Surface Treatment is also the chosen procedure for re-treatment to anyone who had LASIK many years ago, and to correct under corrections after SMILE eye laser.
Patients with the very early stages of keratoconus and a low correction can have PRK combined with corneal collagen cross linking.
The evolution of PRK laser eye surgery has continued since the 1990s with large improvements in excimer laser technology such multi-dimensional eye tracking, customised treatments, the use of Mitomycin-C (MMC) and much better management of post operative discomfort. Advanced Surface Laser Ablation is the new term to refer PRK to acknowledge the newer, superior delivery of PRK.
At the end of the procedure Dr Kent will place a soft therapeutic contact lens on the eye to help to reduce post operative discomfort.
