Figure 4: The change of incisional corneal thickness (ICTd) over time both in microincision group and small-incision group. The figure illustrates the ICT healing process both over time in microincision group and small-incision group within 3 months postoperatively. At 1month or 3 months postoperatively, there was statistically significant difference in ICTd between the 2 groups (both P <.05).
