What Is Orthokeratology? The Basics of Corneal Refractive Therapy (CRT)

Also known as Corneal Refractive Therapy (CRT) and ortho-k, orthokeratology is a non-surgical treatment for nearsightedness (myopia) and other refractive errors. Thanks to ortho-k, you'll be able to achieve focus without the aid of glasses or laser eye surgery. Here's how it works:

Contact Lenses

Ortho-k involves wearing oxygen-permeable contact lenses overnight. During sleep, the contact lenses safely and temporarily reshape the corneas.

Vision by Day

The next morning, you will experience much sharper vision. That's because the ortho-k lenses change your corneal contour so you can focus properly.

Surgery Required

Ortho-k patients don't need LASIK. This option reduces dependence on glasses and contacts by day. For many, CRT is a sensible LASIK alternative.

Who Can Undergo Corneal Refractive Therapy (CRT)? Orthokeratology Candidates 

Patients of all ages can benefit from ortho-k lenses at our Chicago optometry and vision center, serving Midway and Garfield Ridge. Here are some key criteria for ortho-k candidacy:

Nearsightedness (Myopia) and Astigmatism

Orthokeratology is traditionally used to treat mild to moderate cases of myopia as well as slight astigmatism. We'll perform an eye exam and consult your medical history to diagnose and assess any vision issues.

Farsightedness (Hyperopia) and Presbyopia

While most commonly used to treat myopia, ortho-K lenses are also effective in treating hyperopia and presbyopia. Presbyopia is a type of farsightedness that affects patients during middle age and later.

Avoiding LASIK Surgery

LASIK is an effective vision correction option, but some patients are unable or unwilling to undergo laser eye surgery. Ortho-k allows these patients to experience improved vision without surgical treatment.

Especially Helpful for Children

Children tend to benefit most from ortho-k, including patients as young as seven. Orthokeratology at early ages can halt the progression of childhood myopia.

Your Orthokeratology Appointment Corneal Refractive Therapy (CRT) Patient Education

Do you suffer from a refractive error and want to improve your vision without corrective lenses or surgery? During your meeting with Dr. Chander, he will take several steps to determine if ortho-k lenses are right for you:

Explaining the Process

During your consultation, he will explain all phases of treatment and the initial adjustment process. Some patients may need to wear their ortho-k lenses for part of the day until their eyes fully adjust.

"Closed Eye" Evaluation

We offer no-fee "closed eye" evaluations. The patient wears retainer contact lenses for about 40 minutes to experience the feel of treatment. After removing the retainer lenses, patients can usually expect a 50- to 90-percent improvement in vision.

Exploring Types of Lenses

Since each patient has different needs, we also discuss the type of ortho-k lenses needed. We often use Paragon CRT lenses because they provide high levels of oxygen to the cornea and good overall stability.

Discussing Patient Concerns

Getting answers to your questions from an eye doctor is invaluable. Dr. Chander and his team have the training and knowledge to address all of your concerns about orthokeratology, and you can count on them to help you make an informed decision.
