Figure 3
At the 1st postoperative week, (a) in the SBPRK group, the cornea of one of the eyes had light edema, and the epithelium had an irregular defect about 3 mm in the central area, while the BL was well-positioned. (b) In the TransPRK group, the cornea was slightly edematous with nearly intact epithelium. (c) OCT showed a high reflection layer under the epithelium layer in the SBPRK group. (d) The cornea of the TransPRK group had a high reflection obscure layer under the epithelium and some high reflection materials in the stroma.
