Photorefractive Keratectomy
Photo-refractive keratectomy (PRK) was the first refractive surgery procedure performed using the Excimer laser. Initially, this advanced laser technology was developed by IBM for the production of computer chips. In its medical applications, the Excimer laser was found to provide enhanced levels of precision, safety and control in the treatment of various refractive conditions. During the PRK procedure, the outer skin of the cornea is removed and a cool light beam from the Excimer laser is applied to the surface, correcting your vision by reshaping the cornea. Low levels of nearsightedness, farsightedness and astigmatism can be corrected using PRK and Excimer laser technology.
The point of focus is shifted from in front of the retina to directly on the retina by removing tissue from the center of the cornea, making it flatter.
Treating farsightedness
The point of focus is shifted from behind the retina to directly on the retina by removing tissue from the outside of the central optical zone, making the cornea steeper.
Treating astigmatism
A single point of focus on the retina is created by shaping the cornea to be more spherical, eliminating the multiple points of focus. Think of your eye being reshaped to resemble a basketball instead of a football. Astigmatism can be treated while correcting nearsightedness or farsightedness.
PRK is for those who:
- are looking to reduce or eliminate their dependence on contact lenses or glasses
- are 21 years or older
- have had no changes in their prescription for at least two years
- have no health issues affecting their eyes such as Glaucoma or Cataracts
- have corneas too thin for LASIK
Schedule your complimentary evaluation to determine if PRK is the right choice for your vision correction needs. After a thorough exam and testing, our doctors will determine if PRK is an option for you. Contact us at any of our 5 convenient locations for additional information on this exciting procedure.
Alternatives to PRK
Thanks to advancements in laser vision correction technology, patients now have many options for correcting nearsightedness, farsightedness and astigmatism. Dependent upon your vision needs, our experience staff can determine if alternatives to PRK such as all-laser iLASIK, Refractive Lens Exchange (RLE) or the Implantable Contact Lens (ICL) are right for you. At Eye Associates, we are committed to working with each patient through thorough assessment, precise testing and comprehensive patient education to help you make the right choice for your eyes.
