Imagine this: contact lenses worn while you sleep for perfect, lens-free vision during the day

While most people are familiar with corrective lenses, they usually associate them with daytime wear. In fact, there is a lesser known alternative: orthokeratology, or ortho-k for short.

Doctors discovered the benefits of reshaping the cornea with glass lenses as early as the 1940’s but rarely applied the technology, before 17 years ago. The alarming rise in myopia among the Asian populations has brought about an increased awareness of ortho-k lenses as research has shown that it is a good method for controlling the progression of myopia in children.

What it is

Orth-k employs the use of specialty gas permeable contact lenses, worn overnight. As you sleep, these lenses gently reshape your corneas (the clear front surface of your eyes). When you wake up, you remove them and see clearly for the remainder of the day.

The effects of ortho-k typically last one to two days but, for best results, you should wear the lenses every night. Unlike laser eye surgery, where the outcome is permanent, the results are reversible. This lens technology allows you to function without contacts or eye wear throughout the daytime hours.

What the process involves

Your optometrist will use a machine called a topographer to map out the front surface of your eye, allowing for the design of custom lens that will temporarily reshape your cornea. A highly oxygen-permeable material is used to make these lenses, which allows your eyes to breathe while wearing them. Once a lens is designed, your optometrist will ensure the design is optimal for your eye, as well as teach you to insert and remove the lens safely.

Who is a candidate

Ortho-k is a great option for patients who have mild to moderate myopia (nearsightedness) with or without astigmatism. It has also been shown to slow the progression of childhood myopia. A 5-year study initiated in 2009 evaluated the effect on

A 5-year study initiated in 2009 evaluated the effect on orth-k on myopia progression in 138 patients. Results after one year revealed that subjects wearing the ortho-k lenses exhibited significantly less progression compared to control subjects.It is also great for patients who are ineligible for LASIK refractive surgery; for people who find contact lenses uncomfortable or; for those who engage in sports and have active lifestyles.

The risks

Orthokeratology is a safe and reversible procedure. All contact lens wear comes with a small amount of risk. These can include: infection, pain, redness, tearing, irritation, discharge, abrasion of the eye or distortion of vision. The risks are usually temporary conditions which will be resolved if you visit your eye care professional promptly.

Ortho-k is a terrific option for

Individuals who are nearsighted, with or without astigmatism; people who do not desire the permanent effects of laser eye surgery, and; as an aid for controlling the progression of myopia in children. See your optometrist to learn more about orthokeratology and to determine your candidacy.
