To investigate the changes in corneal shape and optical performance during and after discontinuation of overnight orthokeratology for correction of myopia. ⋯ Overnight orthokeratology improved uncorrected visual acuity and reduced refractive error but increased corneal irregularity and impaired contrast sensitivity. However, these changes in visual function and corneal shape were reversed after discontinuation of orthokeratology lens wear.
