How effective is ortho-k for myopia?
Ortho-K was shown in several individual studies and meta-analyses to reduction the rate of myopic refractive change by 40%-60% when compared to spectacle wearing. 2 Who is the ideal candidate for Ortho-K?
What are the treatment options for myopia and ocular elongation?
• Alterative/medical therapies. Topical atropine 1%, a nonselective muscarinic antagonist, may be used to slow the progression of myopia and ocular axial elongation.
What are the benefits of Ortho K lenses?
It might be a particularly good option for swimmers and athletes, as contact lenses cause problems in situations where an active lifestyle is involved in many situations. Ortho K is achieved by wearing orthokeratology lenses (ortho k lenses) which enable corneal reshaping therapy, also known as cornea refractive therapy.
Can you decrease myopia progression without wearing glasses?
Imagine what it must feel like to tell a patient that you can decrease his or her myopia progression and they would no longer need to wear glasses or contacts during the day. Not only that, but in order to do this they would wear a contact lens at night, much like how some people might wear a retainer to keep their teeth straight.
Can Ortho-K lenses reduce myopia?
Ultimately, Ortho-k lenses can help to slow the progression of myopia in children which is the leading reason why many optometrists and eye experts consider this type of lens to be the most effective solution for this condition.
Can Ortho-K cure myopia permanently?
Is Orthokeratology Permanent? No. It's temporary. If you stop wearing Ortho-K Lenses regularly while you sleep, your vision will return to its original state in as little as 72 hours.
Is Ortho-K suitable for high myopia?
Ortho-K can correct most prescriptions — myopia (short-sighted), astigmatism (uneven eye surface curvature), hyperopia (long-sighted) and even presbyopia (difficulty focusing with age).
Does Ortho-K improve eyesight?
Ortho-k lenses gently flatten your cornea, allowing light to enter and refract properly. This ultimately gives you better, clearer vision. Ortho-k has even been shown to slow down the progression of myopia by an average of 50%, an important benefit that prevents the condition from worsening.
Is Ortho-K better than LASIK?
Ortho-k has been clinically proven to slow the progression of myopia in children and young adults, making it an excellent treatment for nearsightedness. LASIK, on the other hand, offers no such benefits.
What are the risks of Ortho-K lenses?
Safety Concerns and Side Effects As with all contact lens use, the two most common side effects that occur in patients with ortho-k lenses are corneal edema and staining. Other potential side effects include pain, redness, tearing, irritation, discharge, ocular abrasion or visual distortion.
How much does Ortho-K reduce myopia progression?
Ortho-k has been shown to reduce myopia progression by slowing axial length elongation by slightly less than 50%;14,33,34 ranging from 41-45% in most meta-analyses. When treating patients for myopia control with ortho-k, axial length measurements at baseline and throughout the treatment process are critical.
Who is candidate for Ortho-K?
Ortho-K works best for people with blurry distance vision (myopia or nearsightedness) who require a corrective lens prescription of up to -6.00. Low to moderate astigmatism (un-even eye curvature) may also respond well to Ortho-k contact lenses.

Treatment for Myopia
Many Americans are familiar with the effects of myopia, or nearsightedness. If you’ve ever had difficulty seeing distant objects clearly, then you know how much frustration this common vision problem can cause.
Myopia Lens
This treatment requires specially calibrated, gas-permeable contact lenses that allow oxygen to flow directly to the cornea. Since oxygen is a critical element of eye health, restoring healthy levels is the first step to solving many common problems.
Orthokeratology Treatment in the San Fernando Valley (SFV)
Because the benefits of Ortho-K contact lenses overnight are temporary, it’s important that patients regularly follow up with an orthokeratology specialist. Dr. Leonard and Associates offer orthokeratology treatment at their Panorama City optometry office.
Why do orthokeratology lenses cause myopia to decrease?
Orthokeratology lenses will cause the central cornea to become flatter and the mid-peripheral cornea to become steeper. The reason behind how this causes a decrease in myopia varies among researchers, but a commonly agreed upon theory is that it reshapes the cornea to have an oblate curve.
How does MiSight help with myopia?
Myopia control can also be achieved with soft multifocal contact lens options, such as MiSight, which is the first multifocal contact lens that is FDA approved to reduce myopia progression by slowing down the change in spherical equivalent refraction and reducing the rate of axial length elongation. 5.
When was ortho K invented?
Although it has been highlighted in the past few years as more companies join the mission to reduce myopia with contact lenses, the first ortho-k lens was created in 1962. 1 Dr. George Jessen created his ‘orthofocus’ flat-fitting lenses from polymethyl methacrylate (PMMA).
What is a good candidate for Ortho K?
Good candidates include patients who were older at the start of the Ortho-K treatment, older in age of myopia onset, having larger pupils and a smaller central treatment zone due to higher peripheral myopia. 2.
What Is Ortho-K?
Ortho-k, or orthokeratology, is an innovative non-invasive treatment that removes the need for eyeglasses or daytime contact lenses. The treatment improves vision by lightly reforming your eyes while you are sleeping. It uses specially designed contact lenses you only need to wear before you sleep.
Importance of Myopia Control
Myopia, or shortsightedness, is an extremely prevalent problem that is at epidemic levels. Unfortunately, if you had a diagnosis of myopia as a child, it may mean a higher risk of developing serious conditions such as glaucoma and retinal detachment.
The Basics of Ortho-K
In its most basic terms, this accelerated overnight treatment works by changing the shape or curvature of the cornea. The aim is to change how light focuses on the retina. The cornea is the dome-shaped, clear, and flexible tissue at the front of your eye. Its purpose is to focus light onto the retina. It also plays a huge part in focusing your eye.
Managing Nearsightedness With Ortho-K
If you choose this vision correction option, your eye doctor will need to perform a few important tests. The most important among them is determining whether your eyes are healthy. The doctor will examine your retina and the health of the exterior surface of your eyes. They will also map your corneas using a topographer to determine their shape.
What is Ortho K contact lens?
Ortho-k contact lenses gently reshape the focus of the eye to improve vision and control myopia progression. Nearly 30 percent of Americans suffer from myopia. Myopia, also known as nearsightedness and shortsightedness, is a refractive error that affects the ability to see distant images clearly. Myopia occurs when light enters ...
How does ortho K work?
How does ortho-k correct vision? Ortho-k lenses are designed to float on top of the eye’s tear film and apply gentle water-based (hydraulic) pressure to the front layer of the cornea, called the epithelium. The hydraulic pressure causes the cells of the epithelium to move from the center of the cornea to the periphery.
What causes the epithelium to move from the center of the cornea to the periphery?
The hydraulic pressure causes the cells of the epithelium to move from the center of the cornea to the periphery. This migration of corneal cells leads to a temporary reshaping of the cornea and correction of the refractive error.
How long does it take for ortho K lenses to work?
After the ortho-k lenses are removed, improved vision is generally noticed for 24 to 72 hours. Your eye doctor will inform you how often you will need to wear your ortho-k lenses— some patients require nightly wear, while others may only need to wear them every other night.
Does ortho K help with myopia?
In contrast, by reshaping the cornea for vision correction, ortho-k can help to reduce the rate of myopia progression. As a result of its safety, efficacy, and convenience, ortho-k has become one of the most recommended methods for myopia management and vision correction. LEARN MORE: Guide to Myopia Management.
What Is Orthokeratology?
Orthokeratology, or ortho-K, is a method of myopia correction involving the use of specially fitted gas permeable contact lenses that a patient wears overnight. As the patient sleeps, the lenses gently and temporarily reshape the surface of the eye.
Who Is a Good Candidate for Ortho-K?
Most people who have mild to moderate myopia are good candidates for ortho-K therapy, whether they have astigmatism or not. However, this treatment can be especially helpful for people who work in dusty environments or participate in contact sports, conditions which make contact lens use problematic.
What to Expect
When you begin ortho-K, your local eye doctor will painlessly measure the curvature of your corneas to produce a topographical map of the surface of your eye. He or she may use an existing inventory of lenses for fitting your eyes or empirically order custom lenses to fit later.
