Increased Corneal Toricity after Long-Term Orthokeratology Lens Wear.

Conclusions: Long-term ortho-k lens wear increases corneal toricity after discontinuation of the treatment, which is associated with an increase in refractive astigmatism. A more pronounced change in corneal toricity was found in subjects who were younger to start ortho-k and have been in a longer period of treatment.
