PRK and LASIK use lasers or tiny blades to modify the cornea of your eye to either resolve myopia (nearsightedness), hyperopia (farsightedness), or astigmatism (irregular eye shape).
A small incision is made allowing an opening into the epithelium. Then an excimer laser is used to reshape the cornea.
Pros: Quick Recovery, no stitches, fewer follow up appointments or medications, high rate of success
Cons: Not viable for people with high risk of eye injury, greater chance of dry eye, greater risk of poor night vision
A part of the top layer of the cornea is removed called the epithelium. then an excimer laser is used to reshape the cornea.
Pros: Long history of success, small chance of long term complications, High success rate
Cons: Long recovery time (30 days), requires bandages, more discomfort (lasts several weeks)
Both procedures cost around $2500-$5000 however PRK may be more overall than LASIK due to more post-op check ups
