Question: My child’s power is already -4.00D. Is it too late for Ortho-K?
Orthokeratology (Ortho-K Lens)
Answer: It’s not too late, but it is critical. You are standing on the edge of a cliff. If you don't start now, they will hit -6.00D or -8.00D very quickly. At that level, even laser surgery (LASIK) later in life becomes difficult or impossible because the cornea is too thin.
