Figure 4

At the 4th postoperative week, (a) in the SBPRK group, the cornea was slightly hazy (haze stage 1) in the center of the cornea. (b) In the TransPRK group, the cornea was hazier (haze stage 2) in the center of the cornea. (c) OCT showed that the cornea of the SBPRK group had a thin high reflection layer just under the epithelium. (d) In the TransPRK group, the corneal thickness was 448 μm and had diffused high reflection in the anterior stroma.
