PRK was the first laser vision correction surgery to be approved by the FDA to correct refractive error. As with all laser refractive surgeries, (the) vision correction occurs by changing the shape of the cornea through the removal of corneal tissue. While proven safe, PRK is now largely replaced by other refractive procedures such as LASIK, SMILE, and ICL for most patients. It is still the preferred method of vision correction for certain branches of the military andcan also be a good option for people with a low prescription. Finally, PRK is often performed as an enhancement surgery following LASIK.
Dr. Paul C. Lee, at CCRS, has been performing PRK since 1997.
In PRK or photorefractive keratectomy, a laser is used to correct vision by reshaping the cornea. However, unlike LASIK, a corneal flap is not made. Due to the longer recovery time and discomfort, PRK has been largely replaced by other forms of vision correction surgery such as SMILE or ICL. PRK is still a good option in certain cases.
PRK is considered to be one of the safer procedures. Accordingly, PRK is done when a patient does not qualify for other forms of laser vision correction. However, there are now other procedures such as SMILE and ICL, which are also very safe while not having the disadvantages seen with PRK.
Yes, PRK can be repeated.
PRK is safe and effective; however, the outcome depends on the amount and type of correction. For small corrections, the outcome is the same as LASIK.
While the procedure is not painful, people may experience a different degree of discomfort during recovery. For this reason, we give our patients various medications to help them during their recovery.
As with all vision correction procedures, you want to not wear your contact lenses for several days before the surgery. A longer resting period is needed for hard contact lens wearers.
