All About Ortho K Lenses / CRT

Learn about Ortho K Lenses and CRT

You might have heard about the term Ortho-K, but what does it refer to, and is it suitable for you or your children? CV Optometry enlightens you about it.

Orthokeratology (Ortho-K), also referred to as Corneal Refractive Therapy (CRT), is a non-invasive correction procedure that uses specialized contact lenses to repair vision.

The only two brands of permeable gas material, Ortho-K lenses, approved by the FDA are the following:

- CRT lenses from Paragon Vision Sciences
- VST (Vision Shaping Treatment) from Bausch & Lomb

Ortho- K/CRT at CV Optometry

While traditional contact lenses and eyeglasses offer common eye and vision correction measures, some people desire the convenience and freedom of wearing no lenses during daily activities. Some opt for long-term solutions such as laser surgery (LASIK), while others prefer non-invasive options. The solution is the Ortho-K/ CRT reshaping lenses offered at CV Optometry in Coachella.

How Does Ortho-K/CRT Work?
Ortho- K/CRT uses specialized contact lenses worn overnight. The lenses apply gentle pressure to correct the curvature of your eye cornea to reshape the cornea to focus light properly onto the retina. When the lens wearer removes them in the morning, vision is temporarily repaired according to your prescription from a qualified Optometrist.

The effect lasts for about 12-15 hours at a time, correcting your vision and enabling you to have proper vision during the day without wearing any lenses or glasses.

Ortho-K/CRT lenses have been prescribed in over 50 countries, and over 2 million patients have benefited from using specialized lenses.
Which Type of Eye Patients Can Benefit from Ortho- K?

This treatment is recommended for people with the following conditions:

- Farsightedness (hyperopia)
- Nearsightedness (myopia)
- Blurred near vision (Presbyopia)
- Astigmatism
- Sportsmen
- Workers who are exposed to dirty and dusty environments
- Can help slow down myopia in younger patients

Ortho-K is also ideal for individuals with viable prescriptions and those who want similar benefits of LASIK (Laser-Assisted in Situ Keratomileusis), but through a non-invasive process to avoid the risks of surgery.

How Effective are the Ortho-K/CRT Lenses Results?

Ortho-K can correct your vision up to 20/20 without using contact lenses or eyeglasses during the daytime. FDA trials for VST and CRT project that more than 70% of patients achieved 20/20 visual acuity after wearing ortho-k lenses overnight. Also, nearly 90% of patients reported a 20/40 and above ability of better legal vision requirement.

Success rates are high for mild prescriptions. Consult with certified optometrists to check your prescription level and the range of success with Ortho-k lenses.

Vision improvement starts as early as day one or two of overnight usage. Depending on the prescription level, the process might last several weeks for full effect and repair. Initially, some halos and glares are likely to affect your vision, and some tasks, such as driving, may require temporary eyeglasses until the CRT lenses fully repair your vision.

Can I Perform LASIK After Ortho-K/CRT?

Yes, LASIK is possible after the Ortho-K process. You would have to stop wearing the ortho-k lenses for some months to minimize the effect. A professional LASIK Doctor will guide you on how long you should wait upon consultation.
