TransPRK Laser Surgery
ASLA was the first surface laser treatment available commercially. The epithelium of the eye is removed through a scraping action. It was commonly associated with some discomfort and longer visual recovery.
However, there has been a significant improvement in this technology since it began. The surgeon can now use a laser to remove and recontour the cornea.
The advantage of TransPRK procedure over its predecessors is that the epithelium (surface layer of the eye) is modified with a laser. This reduces pain and quickens 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 complications in patients with a thin cornea.
Another reason to use TransPRK over LASIK would be if the patient had any sort of scarring over the cornea. Most patients would generally prefer LASIK if they are suitable, as recovery is much quicker.
With TransPRK, on the day of the procedure, the surgeon carefully removes the corneal epithelium. The Excimer Laser then ablates the underlying layers to reshape the cornea.
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.
