Laser eye surgery helps rectify a number of eye problem related to vision. It also help one get rid of spectacles and contact lenses. Before undergoing an eye laser surgery the feasibility of operation is determined by the surgeon, who takes into account medical history and present health of the patient. The most popular form of such surgery is LASIK which has a very high success rate. PRK (Photo Refractive Keratectomy) is another type of laser eye surgery for people with a thin cornea. PresbyLASIK is a type of LASIK which is used to treat bifocal disorders.
The basic difference between all of the above procedures is that in the way the outer layer of eye is removed to reshape the cornea. While LASIK requires a part of the upper layer to be cut and folded back, PRK cuts a very small part of it to perform the procedure. It is actually up to the doctor to determine which type of surgery one requires. The other point one needs to keep in mind is that the cost associated with eye laser surgery varies according to a number of factors and the type of surgery is only one of them and there are no major difference in costs associated in these two types of surgeries.
One should always look into the experience and credentials of the surgeon before choosing one to ensure that the chances of complications are reduced both during and after the procedure.
