How to Choose an Ortho-K Optometrist: 7 Questions to Ask

How long have you been fitting Ortho-K lenses, and how many patients have you treated?

Experience matters enormously in ortho-k. Ask specifically about paediatric experience — fitting a restless 9-year-old is very different from fitting a motivated adult. Look for an optometrist who has been doing this for at least 3–5 years and has managed at least 100+ patients. High-volume practitioners tend to have better protocols and faster troubleshooting when issues arise.

What is your success rate, and how do you define success?

A good ortho-k practitioner should track and be willing to share their outcomes data. Key metrics to ask about:

Vision correction success: What percentage of patients achieve 20/20 or better within 2 weeks? What percentage achieve 20/30 or better?

Myopia control success: What is the average reduction in myopia progression for your patients versus untreated controls? Can you share any published or internal data?

Dropout rate: What percentage of patients discontinue treatment? High dropout rates may indicate comfort or compliance issues that aren't being managed well.

What does your follow-up care schedule look like?

Ortho-K is not a set-and-forget treatment. Your child will need regular monitoring. A quality practitioner should offer:

Initial follow-up within 1–2 weeks of first fitting, then monthly for the first 3 months, then 3-monthly ongoing. Ask specifically about what happens if a check-up reveals a problem — can you get an urgent appointment? Is there an after-hours line?

Also ask what equipment they use for monitoring — corneal topography (mapping) should be used at every major review to ensure the cornea is responding correctly.

Can you give me a complete cost breakdown — not just the lens cost?

Ortho-K pricing can vary enormously, and some practices make their profit on hidden fees. Ask for a full breakdown including:

Initial consultation and fitting fee, cost of lenses (and whether annual replacement is included), follow-up appointment costs, corneal topography fees, solution and care product costs, emergency appointment fees, and any discontinuation or lens change fees.

Compare practices on the total first-year cost, not just the monthly subscription figure. Some cheap up-front quotes hide high follow-up charges.

Do you have an emergency contact or after-hours support line?

Ortho-K involves a foreign body in your child's eye every night. Problems can develop quickly — a scratched cornea or an ill-fitting lens won't wait until Monday morning. Ask whether the practice offers:

An after-hours phone number for urgent issues, same-day emergency appointments, a direct line to the ortho-k specialist (not just a generic reception), and clear guidelines on what constitutes an emergency vs. a routine concern.

What lens brands do you work with, and why do you prefer them?

There are several reputable ortho-k lens brands including Euclid Systems, Paragon CRT, Emerald, and BEES. A skilled fitter should work with at least 2–3 different systems and be able to explain why they choose a particular lens for different prescriptions and corneal shapes.

Be cautious of practitioners who only offer one brand — this may indicate they are contracted to a particular manufacturer rather than choosing the best lens for each patient.

What does the trial process look like, and what are my options if it doesn't work out?

Before committing to full treatment, ask whether they offer a supervised trial period. This typically involves fitting diagnostic lenses for 1–2 nights, then evaluating the corneal response before proceeding. Ask about:

Whether a trial fitting is included in the initial consultation cost, what happens if your child can't tolerate the lenses during the trial, what percentage of trial patients proceed to full treatment, and whether you get a full refund (or partial refund) if the treatment is deemed unsuitable after the trial.
