Orthokeratology, or Ortho K, is a method of correcting and controlling short-sightedness (myopia) in children and adults through the use of specialised contact lenses worn only during sleep.
Wouldn't it be great if you could be free of glasses and contact lenses throughout the day, without having to undergo surgery?
The recent advances in contact lens design, combined with the latest technologies used to measure the exact dimensions of your eye,has made this possible!
What is Orthokeratology?
Orthokeratology, also known as Ortho-k or Corneal Reshaping Therapy (CRT), is a non-surgical treatment that reshapes the cornea (front surface of your eye)using specially designed contact lenses thatare worn whilst you sleep. Orthokeratology is used in the management of myopia (short-sightedness) and low to moderate astigmatism (irregularly shaped cornea).View Video
What is myopia and astigmatism?
Myopia, often called short-sightedness, is a common focusing condition of the eye. In myopia, the eye ball tends to be longer than usual and therefore the eye cannot focus objects clearly on the retina (the back inner surface of the eye that relays visual information to the brain).
Astigmatism is also a common focusing condition of the eye. Astigmatism is usually caused by an irregularly shaped cornea or lens inside the eye. The eye is therefore unable to focus objects clearly on the retina and the object of interest appears blurred or distorted. For a detailed description of myopia and astigmatism please watch the short web-videos provided (see right).
How does orthokeratology work?
Similar in appearance to standard contact lenses, CRT therapeutic lenses gently reshape the corneal surface during sleep and provide clear, natural vision when the lenses are removed upon waking. The result is temporary correction of myopia (short-sightedness) with or without moderate astigmatism (irregular surface of the cornea). For some people, Orthokeratology slows down or even halts the progression of short-sightedness altogether! This is a very exciting therapeutic treatment, especially for today's teenagers who seem to be affected more than previous generations due to excessive indoor activity and computer use.
What are the benefits of Orthokeratology?
Ortho-k offers freedom from glasses and the hassle of wearing contact lenses during the day, enhancing the lifestyle of those requiring vision correction. Active individuals can freely participate in sports without the interference of glasses or bother of contact lenses. As these special lenses are worn whilst sleeping, eye irritation and dryness often associated with the combination of contact lens wear, extended computer use and outside dust and pollutants, is eliminated. Orthokeratology is a safe and effective, surgery free method of managing myopia and low to moderate astigmatism.
Why have I not heard about Orthokeratology before?
Orthokeratology has been around for decades, however the recent advances in contact lens technology has brought it to the forefront of myopia/astigmatism control. The practice of Ortho-K requires a great deal of technical skill and specialized equipment. The Eye Practice specialises in contact lens fittings and Orthokeratology and we have achieved excellent results in the management of myopia and low to moderate astigmatism.
