Inclusion criteria
Inclusion criteria: Patients were included if they were >18 years old, their central corneal thickness (CCT), bilaterally, was between 510um and 560um and their manifest spherical equivalent between -3.00D and -8.00D with 18 years old, their central corneal thickness (CCT), bilaterally, was between 510um and 560um and their manifest spherical equivalent between -3.00D and -8.00D with <1.50D cylinder. The patients myopic course had to be relatively stable, with no greater than 0.50D of myopic shift per year for two years prior to enrollment.
