This study aims to assess the corneal epithelial remodeling within a 9\u2009mm diameter zone induced by small incision lenticule extraction (SMILE) and evaluate its relationship with the refractive outcomes. Methods. A total of 64 eyes of 64 patients were included. Wide-field optical coherence tomography (OCT) was used to measure the epithelial thickness (ET) across a 9\u2009mm diameter area, preoperatively, and after one day, one week, one month, three months, and six months postoperatively. The ET changes were compared among the different time points and analyzed zones. Results. The ET increases from one week to three months and stabilized from three months to six months. Compared to the preoperative values, the mean ET changes at six months in central (2\u2009mm), paracentral (2\u20135\u2009mm), mid-peripheral (5\u20137\u2009mm), and peripheral (7\u20139\u2009mm) zones were 4.37, 4.36, 1.61, and \u22121.59\u2009\u03bcm, respectively. The correlation between the epithelial thickening and the amount of myopia correction was positive in central (<jats:inline-formula>\n                     <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\">\n                        <a:mi>P<\/a:mi>\n                     <\/a:math>\n                  <\/jats:inline-formula>\u2009=\u20090.001) and paracentral zones (<jats:inline-formula>\n                     <c:math xmlns:c=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\">\n                        <c:mi>P<\/c:mi>\n                     <\/c:math>\n                  <\/jats:inline-formula>\u2009&lt;\u20090.001) and negative in peripheral zone (<jats:inline-formula>\n                     <e:math xmlns:e=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\">\n                        <e:mi>P<\/e:mi>\n                     <\/e:math>\n                  <\/jats:inline-formula>\u2009=\u20090.006).
