All PLE cases developed ectasia following myopic LASIK. Normal control eyes were selected from refractive surgery candidates with normal preoperative corneal tomography and no evidence of ectasia during a postoperative follow\u2010up period exceeding 1\u2009year. Corneal topography and tomography were performed using the Sirius imaging system. Uncorrected and corrected distance visual acuities were recorded and expressed in decimal notation. Statistical analysis was performed using the Kruskal\u2013Wallis test with post hoc Mann\u2013Whitney U testing. Normality was assessed using the Shapiro\u2013Wilk test. Due to non\u2010normal distribution, nonparametric tests were used.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 56 eyes were analyzed.
