Patients of age group 20\u201340 years, best-corrected visual acuity of 20\/20, intraocular pressure (IOP) &lt;22 mmHg, pre-LASIK pachymetry &gt;500 microns, and corneal astigmatism \u22643.00 D were included. Subjects with a prior history of refractive surgery, any other ocular or systemic disease, poor-quality scans, intraoperative complications, and missing data were excluded. Corneal biomechanical properties including SSI were analyzed using Corvis ST and compared using the Paired T-test for each group separately at pre-LASIK, and 1-month post-operatively.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Overall, 202 eyes were reviewed, and 79 eyes fulfilled the inclusion criteria.
