In PRK the Excimer Laser is used to reshape the eye but
does not involve creating a flap. The top layer of cells (the epithelium) is
removed and the laser applied to the exposed surface.
The epithelium is the very thin surface layer of cells of
the eye which regenerate quickly. They are removed by softening with an alcohol
solution and then being wiped away. The excimer laser removes tissue in exactly
the same way as in the LASIK procedure. A clear, bandage contact lens is then
placed on the eye and the epithelium regrows beneath it over the next 4-5 days.
During the PRK surgery procedure itself, there is very
little pain or discomfort. However we recommend patients have a week away from
work as there is some pain and stinging for the first 2-3 days after the surgery
and increased light sensitivity. We provide pain relief as needed. Visual
recovery is slower than LASIK, taking up to 7-10 days.
It is essential to use eyedrops for a period of time after
surgery. It is also recommended to refrain from strenuous exercise for 2 weeks
and from swimming for 4 weeks after surgery.
PRK can be a safer alternative than LASIK for thinner,
irregular corneas. PRK is recommended over LASIK for patients who are at higher
risk of eye injury than normal, such as boxers, kick-boxers and professional
Although there is more discomfort and longer ‘down time’
than LASIK, there are less possible risks and complications as there is no flap
created. The final visual outcome is the same as with the LASIK procedure.
