About PRK Laser eye Surgery
PRK (Photo-Refractive Keratectomy) is another method of surgically reshaping the cornea using the excimer laser. PRK is used for the correction for myopia, hyperopia, and astigmatism. The main difference between LASIK and PRK, is that there is no flap created with PRK. PRK is primarily performed when a patient's corneas are too thin for LASIK. Dr. Rohr may also perform PRK after LASIK when patients visit him to have their vision improved after unsuccessful procedures at other facilities.
During this gentle procedure, Dr. Rohr uses eye drops to numb the eye. The outer epithelial layer is gently removed and the excimer laser is used to reshape the cornea to correct the vision, as done with LASIK. Dr. Rohr then places a protective bandage contact lens to assist with the healing process.
Typically, for the first couple days after PRK, there is slightly more discomfort and blurriness than with LASIK. However, normal work activities can usually be resumed within a week. The protective contact lens used to aid in the healing of the cornea is generally left on the eye for up to a week. Dr. Rohr will painlessly remove this bandage lens in the office. Eye drops are generally used for approximately one month, compared to one week with LASIK.
