How long does it take the eye to go back to its original shape after wearing orthokeratology lenses?

I wear orthokeratology lenses and I need to get new glasses. How long do I have to wait before my eye turns back to its natural state and prescription?

Orthokeratology involves wearing rigid gas permeable contact lenses overnight to temporarily reshape the cornea with the goal of changing the overall prescription. This allows you to see without glasses or contact lenses the following day.

If you are planning to stop wearing the orthokeratology lenses, it can take several months for the cornea to return to its original shape. Your ophthalmologist will test your vision over different visits until he or she feels that the prescription is stable. If you are planning on getting refractive surgery such as LASIK, it is essential that you wait until your corneal shape has fully stabilized. In the interim, you may decide to get a prescription for glasses made with the knowledge that it may need to be redone at a later date.
