Although LASIK surgery seems to be the preferred refractive procedure, however in some cases LASIK is not advisable. The PRK is a less complicated procedure, which is appropriate for certain situations.

The majority of surgeons prefer LASIK for patients who have mid to high levels of myopia. The same surgeons prefer PRK to LASIK for patients with thin corneas, inability to get good suction, keratome-related complications, low K readings, deep-set eyes, poor patient cooperation, small lid fissures, severe squeezing, asymmetric astigmatism, or eyes with pachymetry measurements less than 500 um.

Studies show when comparing PRK and LASIK, the results are equal at one year for myopia of two to 5.5 D and myopia up to 14 D. However because of less postoperative pain, faster visual recover, and less corneal haze. Because of this LASIK has become the preferred procedure with the majority of refractive surgeons. Plus LASIK can be used to treat higher degrees of myopia. The majority of patients prefer LASIK to PRK.

There are times when PRK is the preferred procedure. This would be in patients with low myopia and Cogan's dystrophy, corneal erosions, or even with conjunctival scarring after retinal detachment surgery.

Even though the majority of people and surgeons alike prefer LASIK to PRK there are times when PRK is the preferred treatment. The procedures are different with many similarities. The goals of both procedures are the same, so why do people prefer LASIK to PRK. The results of the procedure can be realized much faster with LASIK than with PRK.

There is less discomfort with LASIK than with PRK. The reason for the discomfort with PRK is that most of the pain fibers in the cornea are located in the surface portion and with PRK this is the same area the procedure is performed.

PRK patients will usually need to take pain relief medication for about one to two days following the procedure. It also takes more healing time than LASIK or LASEK. Clear contacts are placed on each eye to prevent infections. After two to five days the lenses will be removed. The layer of epithelial cells will begin to restore itself and the whole healing process will take up to three to four months. During the healing time patients will be given medications to promote healing and prevent infections.

However, PRK is an excellent secondary option for corrective laser eye surgery when LASIK or LASEK is not an option for you for whatever reason.
