Ortho-K

Did You Know?

Orthokeratology has gained popularity as an alternative to traditional vision correction methods, particularly for those seeking freedom from daytime glasses or contact lenses. It also has the added benefit of slowing down the progression of nearsightedness in children.

OrthoK Lenses Q&A

What is Orthokeratology?

Orthokeratology, often referred to as Ortho-K or CRT, is a non-surgical procedure where specially designed rigid gas permeable contact lenses are worn overnight. These lenses reshape the curvature of the cornea temporarily, thereby correcting nearsightedness and astigmatism. The reshaping effect of Ortho-K lenses allows people to see clearly during the day WITHOUT the need for glasses or contact lenses.

Key points about orthokeratology include:

1. Overnight Wear: Ortho-K lenses are worn overnight while sleeping. During this time, they gently reshape the front surface of the eye.
2. Temporary Effect: The reshaping effect is temporary and reversible. If lenses are not worn consistently, the cornea will gradually return to its original shape, necessitating regular use to maintain corrected vision.
3. Vision Correction: Ortho-K is primarily used to correct myopia and astigmatism.
4. Advantages and Considerations: Benefits include improved daytime vision without corrective eyewear and potentially slowing down myopia progression in children. However, Ortho-K requires commitment to nightly lens wear and follow-up care.

Who can wear OrthoK lenses?

OrthoK is for all ages – both children and adults.

I thought it was unhealthy to sleep in contact lenses?

OrthoK retainer lenses are specifically designed to be worn while you sleep. They are a hard lens, but designed for comfort, with features that help retain moisture, and provide high oxygen flow to the eye while asleep. Proper hygiene and care are essential to prevent complications, as with any contact lens wear. Regular follow-up visits are necessary to monitor eye health and ensure the lenses are fitting correctly.

How long does it take to have good vision once starting treatment?

In most cases, at least half of your nearsightedness is corrected within the first 2-3 days. It can take up to 3-4 weeks to achieve optimal vision correction that holds for most of the day. The recommended sleep time in the lenses is at least 6 hours, with best performance of 8 hours.

What happens if I miss a night of wear?

Missing a night of wear will result in slightly blurred vision the next day, depending on your level of correction and vision needs. While it’s not recommended to skip wear at night, it is understandable that it may happen from time to time.

Is OrthoK permanent?

No. OrthoK is not a permanent affect. If you decide to discontinue wear, the shape of the eye will revert back to its original shape.

Does my insurance cover OrthoK?

No. Insurance, both vision and medical, consider Orthokeratology as an elective procedure, so all costs would be out of pocket. However, we have multiple payment plan options available for use.
