Glasses have been the most popular method to control nearsightedness, farsightedness, and astigmatism; however, we all understand the inconveniences of wearing prescription glasses. LASIK surgery is a method to eliminate refractive errors, but not everyone is suitable for surgery. Ortho-K is the solution to these problems.

Ortho-K contact lenses

What is Ortho K?

Ortho K is a non-surgical treatment for refractive error.

This method uses contact lenses worn at night at bedtime to reshape the cornea and correcting myopia. After 1 to 4 weeks, maximum visual acuity can be achieved to stop using prescription glasses.

Who can use Ortho K glasses?

The Ortho-K method is a great solution for those of you who have a desire to get rid of glasses for work, aesthetics, or a yearning for visual freedom. Ortho K is suitable for those who:

• Myopia is less than 8 diop, astigmatism is less than 2 diop.
• Patients who are not old enough for surgery.
• Patients who do not want surgery, or cannot have surgery.
• Demand for high visual quality.
• Job requirements cannot use frame glasses.

It can be said that the Ortho-K method is suitable for treating refractive errors for all ages. However, it is recommended to treat children 8 years of age and older. This is the right age for children to have enough awareness about proper wearing and caring for the lenses.

How safe is Ortho-K?

Ortho-K was approved by the FDA (US Food and Drug Administration) in 2002. It is now widely used in 56 countries. With a wide range of glasses from famous brands in the US such as Fargo, Isee, Paragon CRT... can treat high myopia and astigmatism.

The material of Ortho K is Fluorosilcon Acrylate Polymer with high permeability 100DK. Ensuring an adequate supply of oxygen is crucial to the health of the cornea.

The risks with the Ortho-K method are minimal and the safety is higher than with other lenses.

Why are Ortho-K suitable for treating refractive errors in children?

Nowadays, the percentage of children with myopia in school is increasing day by day. And become a matter of concern for many parents. In addition to wearing glasses to support vision, Ortho K is the optimal method to help treat children's nearsightedness.

Children's eyes are in the developing stage, not yet stable. Therefore, the increase in myopia is a concern when children wear glasses.

The great advantage of Ortho K lenses is that it helps to CONTROL the worsening of myopia. This means when the child uses Ortho K lenses, the increase in prescription will be limited. Or if there is an increase, the increase is less than with wearing glasses.

To achieve high efficiency when using Ortho K glasses, you need to combine with a healthy lifestyle. Get enough sleep, eat well, get enough nutrients. Study and work in moderation in front of computers, phones, with blue light.

Children should start using Ortho-K as soon as possible

Age greatly affects the increasing trend of refractive errors. At different ages, the eyes will develop and change in vision. This directly affects the incidence and progression of refractive errors.

From 0 to 18 years old. This is the period when the eyes develop the most and also the age when the most refractive errors appear. Children with myopia in this stage, if not detected early, can lead to strabismus, amblyopia, affect vision and later life of children.

Myopia in this age group can increase quite rapidly. On average, each year can increase from 0.75 to 1 Diop. If the eyes are not well taken care of, or not ensured a suitable learning environment, myopia can increase faster.

To be able to detect refractive errors early, parents need to take their children to have their eyes checked when they are 6 months old. And periodic eye exams every 6 months to monitor eye health.
