Figure 4 Improvement in refractive error and refraction stability for M, J0, and J45 during the 3 years of follow-up. Error bars represent the SD.

Notes: M is equal to the spherical equivalent of the given refractive error, J0 is the Jackson cross-cylinder with axes at 180° and 90°, and J45 is the Jackson cross-cylinder with axes at 45° and 135°.
