Evaluation of Wide Corneal Epithelial Remodeling after Small Incision Lenticule Extraction (SMILE) with Wide-Field Optical Coherence Tomography

Figure 2

Preoperative to six-month postoperative epithelial thickness changes, in the central (2 mm), paracentral (2 to 5 mm), mid-peripheral (5 to 7 mm), and peripheral zones (7 to 9 mm). The average ET of the central, paracentral, and mid-peripheral zones significantly increased from one week to three months and stabilized from three months and six months. The average ET of peripheral zone decreased at one day, one week, and six months and underwent an increase from one week to three months (n = 64 eyes).
