On average, PRK costs between $1,800 and $6,500, depending on the severity of the refractive error and the degree of customization the patient requires. Doctors often price PRK surgery per eye, although most patients will need to correct both eyes.
1 For patients not covered by health insurance, cataract surgery typically costs $5,000 to $10,000 per eye, for a total of $10,000 to $20,000 for both eyes.2  For example, at Park Nicollet, a hospital in Minneapolis, Minn., it costs about $4,365 per eye -- a total of $8,730 for both eyes. Within five years after cataract surgery, one in four patients develop cloudiness on part of the lens capsule that remains in the eye after surgery; to correct this, a five-minute procedure, called YAG laser capsulotomy, is needed. 2  This typically costs $250 to $450 and usually is covered by insurance.
