Although both methods aim to achieve correction of myopia (short sight) they are radically different. Laser Vision Correction (LVC) is a surgical procedure which creates permanent corneal tissue changes, with all the potential risks and complications, which may arise in a surgical procedure which is irreversible.

Corneal Refractive Therapy (CRT) is a therapeutic, non surgical, reversible tissue manipulation, also known as Ortho- Keratology, which aims to achieve all the benefits of a completely successful LVC without the potential complications. CRT always allows the option to return to normal glasses and contact lenses or even to have LVC if desired.

The permanency of LVC and the reversibility of Ortho-K could be viewed as an advantage and a disadvantage depending on the personal aim of the patient. I think it is appropriate for each individual to consider these options according to their personal perspective. 

Ortho K has a very good safety record; it is a FDA approved procedure. Nevertheless it has to be practiced professionally and used responsibly with strict attention to personal and contact lens wear hygiene.
