Have you heard of the new technology known as Corneal Refractive Therapy (also known as Orthokeratology, Ortho-K ?
Menicon Alpha Ortho k is produced at the factory which is located in Arafa, Kamiina-gun, Nagano Prefecture, Japan. They are 100% assured made in Japan, with thorough safety design . Rest assured, the user can have a peace of mind!
The patient can wear the lens with unprecedented comfort! The lens is produced by using the world’s most advanced production equipment at which the cutting accuracy is as high as “1/10000mm”. It is a fully automated production and it has a thorough management in the quality control. According to the corneal shape of each patient, a completely customized and precised lens is achieved.
Since its establishment in 1970, it has nearly 50 years of research and clinical experiences in Japan!
Even though after Alpha ORTHO-K was approved by the Ministry of Health, Labour and Welfare of Japan, there is still a safety investigation conducted for three-year. There were no reports of severe complications during the investigation period, and the results of effectiveness and safeness were good!
Alpha Ortho k fitting requirement
A careful assessment will be carried out during fitting.
1. Inquiry / vision examination / anterior eye examination
Experience regarding wearing glasses, contact lens usage, cases of eye diseases and systemic diseases will be asked by the optometrist. The condition of the eyelids, eyelashes, cornea, and conjunctiva has to check to confirm whether the patient is suitable to wear “α ORTHO®-K“.
2.Corneal shape refractive examination
Refractive examination and subjective refraction based on the eye chart and refractive lens insert will be conducted. After that, the optometrist will analyze the shape of the cornea and calculate the corneal radius of curvature according to the keratometer and corneal topography.
3. Other tests
Slit lamp microscopic examination, fundus examination, measurement of intraocular pressure, tear secretion test, corneal thickness test, corneal endothelial cell count test, etc.
Follow regular follow-up visit schedule for inspections. After 1 week of wearing the lens or later in future during the inspection, the fluorescein staining will be applied when necessary . If the lens is misaligned, or vision desired after correction is not obtained, the patient will have to come and recheck again in 1 or 2 weeks. If there is no problem in the inspection, the follow up schedule is 1 month, 3 months and regular follow-up visits every 3 months.
Lastly, in order to keep the lens clean, the lens casing must be replaced regularly. It has been reported many eye infections happened due to dirty lens casing.

Menicon Ortho-K Lenses works as a continuous wear lenses to correct myopia. Myope is an eye condition of where distance image appear blur and near image look clear. Normally, the standard correction available for myopia correction is using glasses, contact lens or lasik surgery. Today, there is another great alternative way to correct myopia condition, named as orthokeratology.
Orthokeratology, also known as Ortho-K is a non-surgical procedure of reshaping the cornea gently while you sleep, with a specially designed therapeutic gas permeable contact lens. This type of contact lenses can have a successful fitting by correcting the refractive error, primarily myopia (near-sighted) but astigmatism and hyperopia (long-sighted). Ortho-K sometimes called corneal reshaping (CR), corneal refractive therapy or even vision shaping.
Ortho-K lenses gradually change the cornea curvature overnight to reduce corneal refractive power, resulting in images being focused on the retina. The successful of Ortho-k fitting occurs as vision will be improved after remove the lenses without the needs of wearing any glasses or contact lenses during the day.
The main objective of Ortho-K is help to slow down myopia progression in children. The myopia epidemic in Asia is evident because the prevalence of high myopia among young adults is higher among Asian (6.8% – 21.6%) compared to non-Asian populations (2.0% – 2.3%). [YL Wong et al 2016]
Besides that, Ortho- K lenses is a non-surgical and reversible vision correction treatment. For those children who wish spectacle free during day time activities but too young for LASIK, Ortho-K is the most suitable option. Ortho-K is a specially designed gas permeable contact lens which offers high oxygen transmission to maintain eye health.
Jennifer (2018) stated that when Ortho-K used for partial or full correction of myopia, has been shown to slow down myopic progression in children by 35-56 % as compared to controlled group who wearing spectacle or contact lenses.
The criteria for Ortho-K including myopia below -6.00D and astigmatism below -2.00D. Children and teenagers with myopia progression (power increment) are suitable for Ortho-K treatment. Individuals who are active in sport, individual whose occupation do not encourage eyewear. Ortho-K is another best alternative to LASIK. Compliance and independent characteristics is very important as well.
Ortho-K is a specially designed gas permeable contact lens that wears overnight to reshape the corneal curvature and correct the refractive error which provide a spectacle free clear vision to carry on dailies activities. For more information, do contact your best optometrist in KL
With all that is positive about Ortho-K and their high percentage rates of slowing down the rate of increase Myopia (Nearsightedness), there are side effects that you have to look out for.
Ortho-keratology or Ortho-K is the usage of a specially designed gas permeable contact lens. It is a lens that gently reshapes the cornea or the front surface of the eyeball to reduce or control myopia. Myopia is referred as Shortsightedness or “Rabun jauh”. Some people refer to it as Hard Lens or OK lenses. You wear these lens overnight and you can see clearly when you wake up. After you remove them of course.
