As myopia continues to reach alarming numbers, eye specialists are creating new management approaches. Orthokeratology is a myopia control treatment that involves overnight-wear contact lenses. 
 

The nonsurgical treatment controls myopia by gradually reshaping the eye surface while the patient sleeps. Users can go through the day without wearing lenses. Studies show the treatment is safe and effective, but it is not for everyone. 
 

Your Level of Refraction 

Evidence shows that Ortho-K is effective for people with mild to moderate myopia. It is ideal for patients who do not require high correction. The outcomes are less predictable for people with high prescriptions or levels of refractive correction. 
 

Refractive correction from Ortho-K depends on the corneal thickness. Most studies on the effectiveness of Ortho-K in children involve -0.50D to -0.75D of myopia. Results differ for individuals based on their unique cornea.
 

Ideal Age for Ortho-K

The best candidates for Ortho-K are children under 16 years old. But adults between 17 and 35 can also enjoy the myopia control treatment. Response to treatment is delayed or reduced for adults over 40. While the treatment is ideal for younger children, doctors assess each child’s suitability based on other factors. Handling and wearing the lenses as prescribed is vital for effectiveness. 
 

Correcting Astigmatism 

Ortho-K lenses can help to correct certain levels of astigmatism. Studies show spherical designs can correct corneal astigmatism of up to -1.50D. Patients with greater astigmatism require specialized techniques, such as toric Ortho-K lenses, for optimal outcomes. Accurate fitting is vital for the desired refractive correction. If you have astigmatism, your doctor can tell you if you are an ideal candidate for the treatment.
 

Corneal Topography 

Your corneal measurements will help determine whether you are a good candidate for Ortho-K. During the lens fitting, eye specialists measure the corneal topography to evaluate how effective the Ortho-K myopia treatment will be. They measure corneal eccentricity (flattening between the central and peripheral corneas) and apical corneal power. The results affect the ability to achieve refractive change while using the lenses. 
 

Consider Lifestyle Factors 

Ortho-K lenses are a nonsurgical treatment option that offers the freedom to enjoy good vision without wearing eyeglasses or contact lenses. The lenses are a good option if you are physically active or involved in sports.
 

You may be a good candidate for Ortho-K lenses if you work in dusty environments or in industrial occupations. You can benefit from clear vision without worrying about eyeglasses or contact lenses causing discomfort. 
 

Reduce Dry Eye Symptoms 

If you suffer from chronic dry eye syndrome, it can be uncomfortable to wear soft contact lenses. Ortho-K lenses can be a viable option for you. They eliminate the need to wear contacts during the day. Your eyes can rest, and you do not have to deal with potential irritants. 
 

Wearing Ortho-K lenses overnight does not interfere with tear film stability or meibomian gland function. An eye specialist will assess your eye health to determine if you are a good candidate for Ortho-K. You can consider getting the lenses to avoid vision correction surgery. Eye specialists agree that Ortho-K is one of the best myopia control options.
