TransPRK Laser Surgery
ASLA / PRK / TransPRK correction
ASLA was the first surface laser treatment available commercially. The epithelium of the eye is removed through scraping action. It was commonly associated with some discomfort and longer visual recovery.
However, there has been a significant improvement to this technology. The surgeon can now use a laser now removes and raconteur the cornea, this is called TransPRK. The advantage of transPRK over its predecessors is only the epithelium which needs to be removed is done so with a laser. This reduces pain and quicken recovery. The laser used to reshape the cornea is the same as the latest technology used in LASIK.
TransPRK is often used in two groups of patients. This technology suits patients with thin cornea as creating a flap (LASIK) can have complication in patients with thin cornea.
Another reason to use TransPRK over LASIK would be if the patient had any sort of scarring over the cornea. In general most patient would prefer LASIK procedure if they are suitable, as recovery is much quicker.
On the day of the surgery the surgeon carefully removes the corneal epithelium. The Excimer Laser ablates the underlying layers during the PRK procedure to alter the cornea to the required shape.
When the treatment is complete a “bandage” contact lens is put on the treated eye. The contact lens will remain in place for 3-4 days to allow greater post-operative comfort until the epithelial layer has regenerated.
Instructions will then be provided on the use and dosage of your drops. A clear shield will be placed on the eye. You may remove the shields in the morning of your first post-operative check.
