The inclusion criteria for this surgical technique in our institution were as follows: unsatisfactory correction with spectacles or contact lenses, manifest spherical equivalent of -1.25 to -9 diopters (D), manifest cylinder of 0 to 4 D, sufficient corneal thickness (estimated total postoperative corneal thickness 400 micro-m or more and estimated residual thickness of the stromal bed 250 micro-m or more), endothelial cell density 1800 cells/mm or more.
No history of ocular surgery, severe dry eye, progressive corneal degeneration, cataract, or uveitis. Eyes with keratoconus were excluded from the study by using the keratoconus screening test of Placido disk videokeratography (TMS-2, Tomey, Nagoya, Japan)
