As an optometrist, one of the questions I get most often — from parents of nearsighted kids, and from adults tired of daily contacts — is whether there's a way to see clearly without wearing anything during the day. For the right patient, orthokeratology is that option.

Orthokeratology uses a specially designed rigid lens, worn overnight, to gently and temporarily reshape the cornea. You take the lens out in the morning, and your vision stays clear throughout the day — no glasses, no daytime contacts. It's been FDA-approved since 2002, and in the clinical trials that led to that approval, over 90% of patients achieved 20/40 vision or better. It's now been prescribed to more than 1.5 million patients worldwide.

What I want patients and parents to understand is that this is a temporary, fully reversible effect — if you stop wearing the lenses, your eyes return to their baseline within about 72 hours. Most patients notice improvement within the first few days of wear, with vision leveling off at its best around 10 to 14 days in.

At Michigan Eye Consultants, I'm certified in both Paragon CRT and Euclid orthokeratology systems, and every fitting is customized — we measure your eye's exact shape and adjust the lens design in small increments to get the fit right for you.

Orthokeratology is one of three myopia management approaches we offer, alongside daytime soft contact lens options — so if overnight wear isn't the right fit for your lifestyle, we have alternatives that can achieve similar goals. The right choice depends on your (or your child's) eyes, age, and daily routine, which is exactly what we'll walk through at a consultation.

Common Questions About Orthokeratology

Is it safe?

Orthokeratology has a safety profile comparable to other forms of contact lens wear, with no serious adverse events reported in the FDA clinical study behind its approval. As with any contact lens, following your prescribed cleaning and wear schedule is what keeps it safe.

Does it hurt, or is it uncomfortable to sleep in?

Most patients adjust within the first few nights. The lenses are custom-fit to your eyes, and any initial awareness typically fades quickly as you get used to overnight wear.

How long until I see results?

Many patients notice improvement within the first few days. Vision typically reaches its best, most stable point around 10 to 14 days into treatment.

Is this a permanent change?

No — orthokeratology is fully reversible. If you stop wearing the lenses, your eyes return to their baseline shape and vision within approximately 72 hours.

Who is a good candidate?

Orthokeratology can be a good fit for both children in myopia management and adults who want daytime freedom from glasses or contacts. A comprehensive fitting exam is the best way to know if it's right for your eyes and lifestyle.

How is it different from LASIK?

Orthokeratology reshapes the cornea temporarily and non-surgically, using a lens instead of a procedure. It's reversible and can be a good option for patients who aren't ready for — or aren't candidates for — surgical vision correction.

Is orthokeratology my only myopia management option here?

No — it's one of three approaches we offer. We'll talk through all of your options at a consultation and help you choose the one that fits your eyes and daily routine best.
