Can you comment on the pros and cons of ortho-k gentle corneal reshaping (orthokeratology)? Is it safe for older people (over 40)?
The procedure is an alternative to laser vision correction (LASIK or photorefractive kertatectomy) but it does carry risks of corneal abrasion (scratches to the front of the eye), corneal infections, corneal ulceration (sores). And the vision reverts once the ortho-k is stopped, so the changes are not permanent.
