CRT – Corneal Refractive Therapy

Shaping Your Eyes with CRT in Rockville

Corneal Refractive Therapy (CRT) is the latest advancement in refractive corneal therapy, also called orthokeratology (ortho-k), options. CRT is the latest advance in non-surgical correction of myopia (nearsightedness). This is achieved by wearing gas permeable contact lenses while you sleep, so that no vision correction is needed during daytime hours.CRT image of cornea shaping rockville

Throughout the night, the lenses reshape your cornea gently so that your vision becomes clear the following morning. The correction is temporary, and ideally no eyeglasses or contact lenses will be needed for the next day or two. In order to maintain sharp visual acuity on a daily basis, you need to wear the reshaping lenses every night.

Picture this – With the help of our eye Doctor in Rockville you can have great vision all day long, without glasses, contact lenses or invasive surgery!

Scientific studies have shown that CRT is able to reduce the development of myopia (nearsightedness) in children and teenagers. Parents never again have to watch their children suffer with progressive myopia, year after year.

Previously, adults who were nearsighted needed to either wear glasses, contacts or have laser surgery.  Now, CRT offers a wonderful non-surgical solution. You never again have to worry about glasses, or daily contact lenses and dust, dry eye or allergies. Additionally, laser surgery is only approved for adults 18 years of age and older, while CRT is ideal for children. Especially ideal for children who are active in sports. There is no age restriction at all for CRT candidates.

Please describe what CRT is and give a basic sense of how it works.

Corneal refractive therapy utilizes therapeutic contact lenses to gently reshape the cornea while you sleep at night, which can correct nearsightedness up to -6 diopters and mild amounts of astigmatism.

See it has been approved by the FDA for nearly 15 years and many people enjoy not having to wear glasses or contact lenses during the day, and are used to wearing them at night.

Am I a candidate for CRT/Orthokeratology?

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, namely because it can be discontinued at any point without permanent effects to the eyes.

People who require vision correction and engage regularly in sports, work in extremely dusty, dirty environments, as well as those who suffer from allergies or dry eye and are uncomfortable wearing contacts during the day, will also appreciate the convenience of CRT.

Can Everyone Wear CRT?

paragon_crt_rockvilleNot everyone can wear Paragon CRT. This lens is designed for individuals with low to moderate myopia (nearsightedness) with or without astigmatism (up to –1.75 diopters). Paragon CRT therapeutic lenses are not yet available in bifocal prescriptions for presbyopia (which requires reading glasses or bifocals).

Depending on your needs, you may be fitted in a monovision mode (one eye corrected for near vision and one corrected for distance vision). You might still need reading glasses. However, since there are variations in patient physiology and visual needs, the decision for CRT, at any age, can only be made after a thorough eye exam. At this time, hyperopia (farsightedness) is not correctable with CRT.

The FDA placed no age restrictions on candidates for Corneal Refractive Therapy with Paragon CRT. CRT is being successfully performed on children 12 years old and younger. It can be a great option for children and teens that are active in sports activities or any other extracurricular activities.

Frequently Asked Questions About
Corneal Refractive Therapy (CRT)

Laser surgery after CRT

Refractive surgeries, are possible after treatment with CRT lenses. Yet because CRT works to reshape your cornea, you are required to stop wearing the lenses for approximately several months before undergoing laser surgery. This allows your eyes to return to their original shape.

It’s important to inform your surgeon if you’ve been wearing CRT lenses, and you will be advised as to how long of a wait is necessary before having the laser procedure.
