How Does Ortho-K Work?
Dr. Sweeney at Vision Source Insight Eyecare is an Ortho-K specialist serving Sandy Springs, Dunwoody, Buckhead, and Atlanta. He has been helping patients achieve vision correction using Ortho-K for over 15 years.
What Is Ortho-K? What is Orthokeratology?
Ortho-k or Orthokeratology is a vision correction technique performed by Optometrists such as Dr. Sweeney. The treatment uses specially designed and fitted contact lenses to temporarily reshape the cornea to improve vision. Many refer to this treatment as Corneal Reshaping and it works in a similar way to dental braces but for the eyes. These eye retainers are worn at night, then removed in the morning and vision is perfectly corrected all day. They replace the need for daytime eyeglasses or regular contact lenses without surgery.
How Does Ortho-K Work?
Ortho-K is often referred to as Corneal Reshaping and can achieve vision correction by gently changing the shape of the cornea with the use of special Ortho-K contacts. The cornea is a clear, flexible, dome-shaped window in the front of your eye that is responsible for focusing light onto the retina and attributes the ability of the eye to focus. A slight reshaping of the cornea can have dramatic effects on vision acuity.
The patient will receive a scan from a corneal topographer, an instrument that will map and measure the surface of the cornea. The results of the scan are used to match the unique shape and curves of the patient’s cornea to a precise, custom design of contact lens.
A course of Ortho-K contact lens wear gently reshapes the patient’s cornea. The Ortho-K lenses flatten the center of the cornea thereby changing the trajectory of light entering the eye and how it is refracted onto the retina. A small change in corneal curvature can have dramatic effects on vision correction. The lenses are gas permeable contacts and are sturdy enough to reshape the cornea when worn overnight. The contacts are removed in the morning and the cornea retains the optimized shape for 18-24 hours. The cornea reshaping is repeated the following night when the patients reapply the same Ortho-K contact lens. It can take an initial ramp up period (up to 5-10 days) to achieve a level of reshaping that can then be maintained only by wearing lenses while sleeping at night.
Does Ortho-K Work?
In FDA trials performed in 2005, Ortho-K treatment achieved 20/20 vision in 60% of patients and 20/40 in 90% of the patients. When used as a response to Myopia, specifically in children, it was found to slow the rate of progression by 40-60% versus those treated with eyeglasses.
