Short-Term Effects of Overnight Orthokeratology on Corneal Sensitivity in Chinese Children and Adolescents

Figure 1

Changes in corneal sensitivity at both central cornea (a) and temporal cornea (b) during the 3-month OK treatment period. X axis shows the time points (0 = baseline, 1 = 1 day after treatment, 2 = 1 week after treatment, 3 = 1 month after treatment, and 4 = 3 months after treatment), Y axis shows the corneal sensitivity (mm) means ± SD. Solid line represents changes in central corneal sensitivity, and dashed line represents changes in temporal corneal sensitivity. There was a statistically significant difference between the baseline of central corneal sensitivity and the 1-month time period, but no difference between baseline and 3 months.
