Can Children Have Corneal Refractive Therapy
At this time, the FDA has placed no age restrictions on candidates for Corneal Refractive Therapy. The therapy is being successfully performed on children 12 years old and younger and may be a good option for children and teens that are involved in sports. Visual requirements due to age or activities can only be assessed after a thorough eye exam. Your eye doctor will recommend what is best.
It Can Slow Your Childs Myopia Progression
Many parents are pleased to learn that corneal refractive therapy is FDA approved and has been clinically proven to slow a childs myopia progression in most cases. Many parents like the idea of halting or slowing down myopia, since rapidly progressing or high levels of myopia during childhood increase the risk of developing serious eye diseases in the future.
Thats right CRT can help preserve your childs gift of sight for the long term.
Who Is A Good Candidate For Orthokeratology
Most people with mild to moderate nearsightedness are good candidates for ortho-k.
Because the corneal reshaping effect is temporary, little risk is involved, and you can discontinue wearing the lenses at any time provided you are willing to start wearing glasses or contacts again when your myopia returns.
Children and young adults who want to be glasses-free but are too young for LASIK or are not good candidates for refractive surgery for other reasons often are good candidates for ortho-k.
People who participate in contact sports or work in dusty environments that can pose problems for contact lens wear can also be good candidates.

Is Corneal Refractive Therapy The Same As Orthokeratology
Orthokeratology is defined as the reshaping of the cornea to reduce myopia through the use of rigid contact lenses. So technically, CRT is a type of orthokeratology. However, earlier corneal reshaping designs were limited by the available technology of the time. The newly developed corneal refractive therapy utilizes recent advancements in three highly technical areas: computerized corneal mapping, computerized manufacturing, and oxygen permeable contact lens materials. Each of these produce a therapeutic contact lens design that is unique. This has allowed CRT to become the first corneal reshaping modality to earn FDA approval for nighttime corneal refractive therapy.
Facts About Corneal Refractive Therapy
Millions of people wear contact lenses daily to correct myopia, hyperopia, and astigmatism. Some, however, prefer not to wear contacts during the day and are reluctant to opt for corrective eye surgery.
For those that have low myopia , one option that doesnt require wearing glasses or undergoing a more invasive procedure is Corneal Refractive Therapy . Also known as orthokeratology ortho-K for short it involves wearing special rigid gas-permeable contact lenses designed to gently reshape the cornea during the night, providing temporary clear daytime vision when lenses are removed.

- Inflammation or infection of the eye
- Any eye disease, injury, or abnormality that affects the cornea or surrounding tissue
- Any systemic condition that may affect the eye or be worsened by wearing contact lenses
- Allergic reactions of the eye, which may be caused or exaggerated by wearing contact lenses or use of contact lens solutions
- Eyes that are red or irritated, or suffer severe dryness
In general, ideal candidates can be any age but must have healthy eyes. You should be dependent on glasses or contact lenses and have a desire to reduce this dependence during daytime hours.

Understanding Corneal Refractive Therapy Management
Corneal Refractive Therapy contact lenses are a unique rigid gas permeable design that temporarily corrects nearsightedness by gently reshaping your cornea while you sleep. You may then go throughout the day without wearing contacts or glasses and see great!
How Long Does It Take For Maximum Ortho
This depends on many factors, especially the amount of nearsightedness you have when you begin the ortho-k process.
Some people can have excellent vision after a day or two of overnight ortho-k. But higher prescriptions can take two or more weeks for maximum correction.
Until your eyes are fully corrected, you might notice blurred vision and glare and halos around lights. In some cases, you may need to wear glasses during the ortho-k process.
Also, in some cases, mild glare and halos might persist even after maximum ortho-k correction.

How Much Does Ortho
Fitting ortho-k lenses is a more time-consuming process and requires more expertise than fitting regular contact lenses. It requires a series of office visits and possibly multiple sets of lenses.
Each eye care practitioner determines his or her own fees for orthokeratology, based in part on the doctor’s level of expertise, the time required, and lens costs.
The cost of ortho-k, including follow-up care associated with fitting the lenses, can vary significantly depending on your current eyesight and whether you are choosing ortho-k lenses for long-term myopia control, in addition to the temporary correction of existing myopia.
Costs also can vary based on the region of the country, urban versus rural settings, and the type of practice where you have the procedure performed.
Ortho-k prices in the U.S. generally range from $1,000 to $2,000 , making the procedure about half the cost of LASIK. But particularly difficult cases of ortho-k can cost as much as $4,000.
There are additional costs for replacement ortho-k lenses, lens care solutions and follow-up exams, which can total about $300 to $500 per year.
Normally, orthokeratology is not covered completely by vision care insurance plans, but a portion of the fees may be covered by some plans.
What Should I Expect From The Results
Most patients experience rapid improvement in the first few days of treatment and achieve nearly their optimum vision within 10-14 days. A small percentage of patients will need additional correction to function under all conditions.
CRT is temporary. If you stop wearing the lenses while you sleep, your lens-free vision will return to its original state within a few days.

Corneal Refractive Therapy And Myopia Control
Holly discusses Corneal Refractive Therapy
Corneal molding, or CRT, is a method used to correct or slow the progression of myopia by wearing special hard contact lenses that reshape your eyes overnight, allowing you to be free of glasses or contact lenses during day. While success rates for CRT are generally higher for more mild vision prescriptions, stronger prescriptions can also be corrected. According to FDA trials conducted on CRT lenses, more than 65% of CRT patients were provided with 20/20 visual acuity. A whopping number of more than 90% of CRT patients achieved 20/40 vision or better .
The process is quite simple. The CRT molds are inserted at bedtime and worn as you sleep. Throughout the night, the lenses gently reshape your cornea so that your vision is clear the following morning. The correction is temporary, so in order to maintain sharp visual acuity on a daily basis, you need to wear the CRT reshaping lenses every night.
CRT is very suitable for nearsighted people who are not appropriate candidates for vision correction surgery, such as children. Individuals of all ages with healthy eyes can try CRT. People who require vision correction and engage regularly in sports or work in extremely dusty, dirty environments will also appreciate the convenience of CRT.

How Does Corneal Refractive Therapy Work
Corneal Refractive Therapy works by changing the shape of the cornea so that it is able to refract the light correctly onto the retina and the patient can enjoy clear vision. This is achieved using special contact lenses, which are designed specifically for your eyes and which are worn overnight. While you sleep, the slight pressure that they place onto the eyes, combined with tear film flow, helps to reshape the cornea. However, the cornea is able to retain this shape for some time after the lenses are removed. CRT is progressive, meaning that you need to wear the lenses overnight consistently to achieve the optimal result. You may be able to see an improvement in your vision for a few hours after just one session of wearing them, but your vision will quickly deteriorate as your eye loses the new shape. However, with consistent use, at optimal level patients may be able to achieve and maintain clear vision for as long as 48 hours at a time without glasses or contact lenses. CRT isnt permanent, meaning that if you cease treatment, your vision will return to normal fairly quickly.
Is Crt Safe Reversible
Paragon CRT Lenses have been FDA approved since 2002, and have become a widely accepted and leading alternative to LASIK. The temporary nature of the benefits CRT lenses bring means there is minimal risk involved. Your corneas and eyes will return to normal shortly after you stop wearing the lenses.

If you decide to discontinue CRT, you could choose to pursue a permanent solution like LASIK surgery. Some people are put off by the idea of a permanent surgery because if anything goes wrong, the mistakes are permanent too.
