EyeDream: Ortho-K Vision Correction

Eyesite offers patients Ortho-K lenses, a vision correction therapy that provides clear, comfortable vision without the need to wear contact lenses during the day. We supply EyeDream Ortho-K Lenses as they are some of the best Ortho-K lenses available. These are specially-designed contact lenses that reverse the power of the cornea, at the front of the eye during overnight wear. Once the full effect has taken place, the eye is effectively ‘normal’ and can see clearly during the day.

Benefits of Ortho-K Contact Lenses

There are many advantages of Ortho-K for people of all ages. This nonintrusive eye correction therapy provides an easy way to have clear, natural vision. Ortho-K is a process of gently moulding the cornea to reduce eye conditions by the application of contact lenses worn during sleep.

The goal of Orthokeratology is to give sharp daytime vision without the need for glasses or contacts and without the need of refractive surgery. The cells in the eye can be manipulated and forced to change shape under the lightest external pressure. This allows the lenses to carefully and painlessly change the shape of the eye in order to correct vision. The pressure can be manipulated as the eye changes and grows; a feature very useful in children, whose eyes are not yet fully grown

One of the major advantages of Ortho-K is having clear vision without the need for glasses or contact lenses. This makes Ortho-K an excellent option for professions where such aids could be compromised, such as sports, fire-fighting or work involving dust or dirty environments. They are also a solution for jobs requiring a degree of uncorrected vision, such as pilots or police.Orthokeratology is a safe alternative to laser eye surgery. Laser eye surgery can be expensive and require several consultations.

Children have a great deal to gain from the advantages Ortho-K offers. Studies have demonstrated that adoption of Ortho-K in children can slow the advancement of myopia by significant degrees.

Advantages of Orthokeratology

• Clear daytime vision without the need for glasses or contact lenses.
• No surgical procedures needed
• Reversible process
• No hazy vision of similar post-laser-surgery conditions
• Modifiable as your eye conditions change
• Pain-free
• Child-safe
• Safe and well-understood technology

How Does Ortho-K Work?

Essentially, Ortho-K works by using firm contact lenses to reshape the eye, allowing 20/20 vision without the need for glasses.

While rigid lenses are generally considered to be not as comfortable as soft lenses, overnight Ortho-K is generally very well accepted, since the main cause of rigid lens discomfort during waking hours is the feeling of the eyelids moving over the lens edges while blinking. Since Ortho-K lenses are worn when you’re asleep, there is no blinking and therefore generally no residual feeling of the lens after the adaptation period.

60% of your eye’s focusing power comes from the cornea. The cornea is extremely sensitive to very small changes. For example, 6 µm flattening of corneal thickness (around 5% of the thickness of a human hair) results in 1 diopter of changed vision in myopia. So a specially shaped lens can be used to lightly press the cornea, causing it gradually to be reshaped to the correct shape for focused vision.

The corrective effect lasts up to 72 hours once initially acclimatized, which is long enough to be a practical means of eyesight correction. There is some evidence that unlike other eyesight correction mechanisms, Ortho-K may also reduce future or ongoing eyesight changes or increased myopia, particularly in children.

Risks are comparable to ordinary contact lenses, since they are typically worn for much shorter periods (6–8 hours rather than daytime or 24/7) and while asleep rather than while active. They also compare favourably to surgical correction since no surgery is involved.

Corrections to the shape of the eye are handled over time, and it is considered generally safe for children. In addition, Ortho-K is broadly not new from a safety viewpoint; contact lens safety generally speaking is considered to be well understood. However it is important, as with all contact lenses, to maintain good cleaning and hygiene discipline.

How Long Does Ortho-K Last?

The effects of Ortho-K last for around 72 hours. Once patients have acclimatised themselves to Ortho-K, they commonly experience noticeable improvements within a few hours of use. With regular use of Ortho-K, you can expect to experience 20/20 daytime vision after a week.

Ortho-K lasts as long as it is implemented regularly. Because of the nature of the correction, they must be used on a regular basis. After a few days of not using the lenses, the cornea will start to lose its shape and return the patient’s vision to its original state. However, with regular use and an upkeep of good eye health and hygiene discipline, Ortho-K can be used for a lifetime.

Ortho-K For Children

Orthokeratology (Ortho-K) for children is an easy and convenient way to correct your child’s vision. Ortho-K allows for overnight vision correction, removing the need for glasses or conventional lenses. This gives your child the confidence to play without the fear of losing a lens or breaking their glasses. No more standing on the sidelines!

Myopia can lead to a shopping list of eye problems in later life. The same is true of short-sightedness. Short-sighted eyes are more susceptible to retinal tears or detachments because of the stretching but upon the eye. Thankfully, Ortho-K allows children to slow the advancement of degenerative eye problems using firm, ‘retainer-like’ contact lenses.

Ortho-K For Astigmatism Sufferers

If you suffer from Astigmatism, Orthokeratology can be a non-intrusive way to correct your sight. Ortho-K lenses reshape your cornea to improve your vision.

Astigmatism is a common and usually minor eye condition that causes blurred or distorted vision. It occurs when the cornea or lens isn’t a perfectly curved shape. People who suffer from myopia or hypermetropia may also suffer from astigmatism. Ortho-K can help with all of these refractive error conditions.

If left untreated, astigmatism can cause headaches, eye strain and tiredness. These symptoms are compounded after periods of concentration and long-term focus.

Astigmatism is usually the result of an irregular-shaped cornea or lens. The cornea should be regularly curved like the surface of a football, but in cases of astigmatism it has an irregular curve, more like the shape of a rugby ball. This means that light rays entering the eye aren’t focused properly, creating a blurred image.
