We thank Dr Davidorf for his letter to the editor concerning the Contact Lens and Myopia Progression Study.1 We hope to clarify Dr Davidorf’s concerns about the effect of contact lenses on corneal curvature. Subjects in the Contact Lens and Myopia Progression Study did not discontinue contact lens wear prior to their annual examinations; we examined the children while they were wearing their habitual vision correction. This study design decision did not concern us because multiple interruptions of contact lens wear would be inconvenient and might have a negative impact on compliance. We feel we accounted for the effects of the cornea by monitoring corneal curvature and by measuring the axial growth of the eye, which is unaffected by changes in the cornea.
