Several reasons and factors lead individuals to choose PRK over LASIK. The first reason is that they may not be suitable candidates for LASIK. The two most common disqualifying factors are chronic dry eyes or corneas that are too thin. As no corneal flap is created with PRK, patients with chronic dry eyes may be far less affected during the recovery process, and less cornea tissue is disturbed in PRK than what is
necessary to make a LASIK flap.
The other main reason that people will choose PRK over LASIK, despite being a good candidate for both, is because PRK is much more appealing for those with active lifestyles. Since there is no residual corneal flap present, PRK patients will never experience flap-related complications that LASIK patients can experience in sports, certain types of jobs, etc.
