The patient will be asked to look in a particular direction. The physician will apply laser spots to the desired areas of the retina.
Patients will notice flashes of light and a mild-moderate burning sensation associated with each laser spot. The procedure may take anywhere from 5-20 minutes, and may need to be repeated 1-2 times.
Many patients find it helpful to take a tylenol prior to the procedure.
The vision will be dark followed by different colors for a few minutes after the procedure, but thereafter, the central vision should return near normal. There may be a slight blurriness, which typically resolves after any remaining gel from the contact lens is rinsed out. The eye is typically sore for approximately 1-2 days. Tylenol may help with any discomfort. Artificial tears may be useful for any irritation of the front of the eye. Sensitivity to light is common, and it may be helpful to use sunglasses when outside.
PRP is known to cause a decrease in the peripheral vision as well as prolong the time needed to adapt to a dark environment. That being said, most patients do not notice any change in vision. This procedure is only recommended in patients who have sight-threatening eye conditions, which if untreated, would lead to blindness and possible loss of the eye.
