Keratoconus
When glasses and soft lenses stop giving a steady picture
A lens corrects how you see. It does not change the cornea.
In keratoconus the cornea thins and bulges toward a cone shape, which bends light unevenly. Glasses and soft lenses may not correct that, and vision can shift from one month to the next. A scleral lens puts a smooth optical surface in front of the uneven cornea. It does not change the cornea or the condition, and your cornea doctor can speak to that. Results vary.
How we fit for keratoconus
Maps of the cornea at every visit
Lens changes as the eye changes
Your cornea doctor kept in the loop, with your permission
- Sudden vision loss, flashes of light, a curtain over your vision, a chemical splash or an eye injury needs care now. Call our office right away or go to an emergency room. If you can't reach us, call 911.
Alongside your other doctors
Your lenses and your corneal care work together
With your cornea doctor
With your permission, we send our measurements and lens notes to your cornea doctor, and we ask them about anything that could change your plan.
Between checks
Keratoconus can change over time, so we compare the maps from each visit with the last and tell you what has moved.
When we refer
If an exam shows something that needs a cornea doctor or a medical eye doctor, we refer you, and we say so plainly.
Keratoconus and lenses, answered
Can a lens slow keratoconus?
No. A scleral lens corrects how you see. Whether anything can slow the condition is a question for your cornea doctor, and we are glad to work with them.
Do I need a referral to book?
Not to book a fitting. If you have a cornea doctor, tell us who it is and we will ask your permission to share our notes with them.
Will I need new lenses if my eye changes?
Possibly. When the shape of the eye changes, a lens may need changes or a new design. We check the fit at every follow-up visit.
Bring your last corneal maps
If you have maps or a letter from your cornea doctor, bring them to your first visit. If not, we start with our own.
