How listings work
What each label means, where facts come from, and what we don't claim.
Where listings come from
Every listing is built from official public pages: the office's own website or its institution's program pages. For each fact (name, address, phone, each service) we keep the page link and the date we checked it. The current listings were checked between 2026-10-20 and 2026-10-22; each listing shows its own date.
We do not include listings from reviews, ads, scraped directories or guesses. If a detail isn't on an official page, we leave it out.
Service labels
- On site: the location's own page says the service is performed there.
- Referral: the office's page says it refers patients elsewhere for that service. Cross-linking by referral is never shown as performed on site.
- Program lists it; location to confirm: a department or program page names the service but does not tie it to this address. These are shown separately in search, and you can hide them with "Show only location-page evidence".
- Not stated on source: unknown. It does not mean the office doesn't offer it. Ask the office.
Three different kinds of checking
- Source checked: we saw the fact on the official page on the date shown. All current listings are at this level.
- Office confirmed: the office confirmed specific details directly. A listing says which fields and when. Until then it reads "Office confirmation pending".
- License verification: we do not verify licenses or credentials. You can check a clinician's license with your state licensing board.
How search works
You can search by city and state, a state, an exact 5-digit ZIP, or a city name alone. A city name alone matches that city in every state, and results show each listing's state.
ZIP and city searches show listings within a chosen radius. Distances are straight-line estimates between U.S. Census ZIP-area or place centers, not driving distances or geocoded office addresses. There are no map pins. A program may list a contact address without confirming where a service is performed, so confirm the care location with the program.
Results are alphabetical within each group: location-specific matches first, then program listings to confirm, then nearby records whose source doesn't state the service. There are no ratings and no paid ranking.
Coverage
The directory is growing and does not include every keratoconus specialist. State pages show how many source-checked listings we have; a zero means we have no record yet, not that care isn't available. Browse all states.
Insurance, costs and appointments
We don't list insurance plans, prices, wait times or appointment availability, because they change often and vary by plan. Ask the office directly.
Sponsorship
Any paid placement is labeled "Sponsored". It never changes a listing's evidence, labels or search order. Listing is free. Sponsorship.
Updates and corrections
Anyone can report a correction. Send the correct detail and an official page that shows it; we recheck the source before changing a listing and update the checked date. Every listing page has a prefilled "Report a correction" button.
Other places to look
Independent organizations with their own criteria. We don't control or verify their lists, and inclusion there is not a KeratoconusRegistry listing.
- National Keratoconus Foundation: Keratoconus referrals(opens in a new tab)
NKCF's own referral service. Their criteria and review are theirs, not ours.
- American Optometric Association: Find a doctor(opens in a new tab)
A general optometrist locator. It does not indicate keratoconus experience; ask each office.
- Scleral Lens Education Society: For patients(opens in a new tab)
Patient information about scleral lenses, including how to look for a fitter.
Your own eye doctor can also refer you to a cornea or specialty lens practice.
