Frequently Asked Questions

What is Orthokeratology?

Orthokeratology (Ortho-K) is an FDA-approved, non-surgical procedure in which Dr. Rozenberg personally designs a series of rigid lenses that are customized to create a change in the shape of the cornea. They are worn while you sleep, and removed when you wake. The result is clear vision, with no glasses or contacts while you are awake.


How does it work?

Ortho-K works by gently and painlessly changing the shape of the cornea while you sleep.

The process begins with the design of a tear layer. The gentle pressure of the tears behind the Ortho-k lens causes the cornea to change from its original shape to a newly designed and preferred contour that gives the patient clear eyesight without glasses or contacts while awake.

Software analyzes Dr. Rozenberg’s design and converts this information into a contact lens that will be created for you with multiple complex curves that are matched to the unique shape of your cornea (similar to your fingerprint).


Is ORTHO-K safe?

Yes, completely. Orthokeratology is an FDA-approved, non-surgical procedure that Dr. Rozenberg has practiced for nearly 4 decades. Ortho-K is completely reversible and you are able to stop at any signs of discomfort.


Is ORTHO-K right for me?

If you want to be able to see throughout the day without the need of contact lenses or glasses and you don't want to get surgery, then Ortho-K is right for you and you should chat with Dr. Rozenberg.

Orthokeratology (Ortho-K) is ideal for both children and adults, nearsighted, farsighted, and astigmatic patients, as well as those over 40 who find they need help for everyday reading (presbyopia) but don’t want to wear reading glasses.

Ortho-K is a perfect choice for any adult who is active during the day and doesn’t want to deal with contact lenses or glasses. It’s also a great choice for children who need vision correction – without the hassles of caring for contact lenses or glasses during school, at sport or other daytime activities.


Should kids do Ortho-K?

YES! Especially for kids and young adults, Ortho-K can stop the eyes from progressively getting weaker. This can be a gigantic health benefit. 

Studies show that Ortho-K lenses can stop the progression of myopia in children as well as adults. Dr. Rozenberg has patients who started Ortho-K at an early age and avoided anticipated vision loss as they grew older. Patients may stop using Ortho-K at anytime, resulting in a return to their original/natural corneal shape.


How long does it take to get results?

Most patients will see a difference in the clarity of their vision within in the first few days.


How long will my clear vision last?

In most cases you’ll have clear vision for all your waking hours. If this is not so, Dr. Rozenberg will work with you to perfect your lenses in order to ensure this result.


How much does Ortho-K cost?

During your complimentary consultation, Dr. Rozenberg will evaluate your case and discuss the fees and time frame expected for your treatment.
