“Braces for the eyes” Orthokeratology (also referred to as Ortho-K), Corneal Reshaping Therapy(CRT), Night lens or OK lens in short. These hard lenses are worn at night when you’re sleeping. It is an FDA-approved non-surgical procedure that can temporarily correct refractive errors (mainly for myopia and astigmatism). It also helps to slow down the progression of myopia by utilizing rigid gas permeable contact lenses to reshape the cornea, so that objects can be focused on the retina without wearing glasses or contact lenses. Suitable for both children and adults. 

Ortho-K night lens slows down the growth of our eyeball axial length, this can be measured accurately with an Optical Biometer AL Scan. A more elongated axial length of the eye of the child means worsening of short-sightedness which will lead to higher myopia prescriptions.

An Ortho-K assessment is required to find out your suitability for these lenses.

What You Should Know About Orthokeratology?

Orthokeratology/Ortho-K is a non-surgical procedure using customised hard contact lenses to gently shape the curvature of the cornea to improve vision, most wearers will not need to wear glasses during the day wn they are on Ortho-K. Most are able to achieve 6/6 visual acuity binocularly during the day.

The main advantage is they can see clearly all day long without the need for glasses or contact lenses. Orthokeratology benefits both children and adults. For children and those who have progressive myopia worsening year after year. A major benefit is that Ortho-K have been shown in various clinical studies to slow down myopia progression significantly – CRAYON STUDY from OHIO State University USA ; LORIC Study from Hong Kong Polytechnic University; ROMIO Study Australia.

Ortho-K procedure is FDA approved. It does not permanently alter your cornea shape and is reversible once you stop wearing them. Ortho-K (cornea reshaping) started over 70 years ago. Modern technology in design and production makes it a reliable and precise way of safe vision correction.

It is a process that uses customised specialty gas permeable contact lenses to reshape the curvature of the eye to improve vision. A safe & effective treatment to correct short-sightedness, astigmatism. Most Ortho-K wearers will achieve functional clear vision during waking hours & didn’t feel the need of using any glasses or contact lenses throughout the whole day. The wearers wear the lenses at night to sleep, in the morning they remove the lens after they woke up. They do not need to wear any glasses to school or to work after that.

There is no age limit. However, an Ortho-K assessment is needed to ensure your eye health is optimal to onboard the program. Children as young as 5 yrs old or someone age 70 can be fitted with the lens. Some common causes that are not suitable are underlying eye diseases such as Keratoconus. The reason for children to be on Ortho-K lens is to manage myopia progression. For adults, due to lifestyle like active in sports or somebody that just don’t like to wear glasses. If you are unable to wear a contact lens due to allergy, dry eyes, dusty working environment, or tired eyes after staring at the computer screen, you're a potential candidate to use Ortho-K night lenses.

The wearers need to wear the lenses almost every night to maintain the required shape for optimal effect. Each pair of night lenses may last up to 1 year and differs individually due to handling and aftercare. If you decide to have laser surgery done after wearing Ortho-K for years, you'll need to stop wearing Ortho-K for 2-4 weeks for the cornea to normalise to its original shape before any refractive surgery consultation.
