What is Orthokeratology?
Orthokeratology, also referred to as Ortho-K, Overnight Vision Correction, Corneal Refractive Therapy or CRT is a sophisticated non-surgical process that temporarily reshapes the cornea while you sleep using specially designed oxygen permeable therapeutic contact lenses. You remove the Ortho-K Lenses when you wake up and can go throughout the day without any other vision correction.
I’ve never heard of Orthokeratology, is it new?
The idea of contact lens corneal reshaping is not a new concept. The process was referred to previously as Orthokeratology and was only as successful as technology allowed. For this reason, many doctors and patients elected not to participate in Orthokeratology. Recent advancements in computerized corneal mapping, computerized manufacturing, and oxygen permeable contact lens materials have produced therapeutic contact lens designs that were not possible before.
Is Orthokeratology safe?
Ortho-K Lenses are very safe. Ortho-K Lenses are therapeutic lenses designed and approved by the FDA for overnight application. We use only FDA approved materials from reputable manufacturers. It is safe for children and adults.

Do all eye doctors perform Orthokeratology?
No. Doctors who perform Ortho-K are specially trained and certified to perform Ortho-K. Dr. Mendelson, FIAOMC, Dr. Johnson, and Dr. Lau, FSLS, have extensive training in Ortho-K and have performed this technique with a combined experience of nearly 40 years with thousands of satisfied Ortho-K Lens patients. Dr. Mendelson has the designation of FIAOMC, a Fellow of the International Academy of Orthokeratology and Myopia Control. This designation is earned after fitting hundreds of patients and passing extensive written and oral exams with case study reports.
