Patients aged 18 years or older with myopia up to -12.00 D and\/or astigmatism up to -6.00 DC and who underwent femtosecond LASIK were recruited. Patients were divided into three subgroups: low myopia (-0.50 to -3.00 D), moderate myopia (&gt;-3.00 to \u2264-6.00 D), and high myopia (&gt;-6.00 D), according to their pre-LASIK spherical equivalent (SE). The variables included for analysis were PCC (central 0\u20133.0 mm, pericentral 3.0\u20136.0 mm, and peripheral region 6.0\u20139.0 mm), PCE, PCA, internal anterior chamber depth, intraocular pressure, and central cornea thickness at the pre- and post-LASIK stages.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      The central PCC remained unchanged across all three myopia subgroups at 1 month when compared to the pre-LASIK stage and remained stable at 6 months.

This trend was not seen in the peripheral cornea regions, which remained unchanged at 1 and 6 months post-LASIK when compared to pre-LASIK mean readings. There were minimal changes in post-LASIK posterior cornea astigmatism throughout follow-up.
