Keratoconus is a progressive corneal disorder that affects about 1/100,000 people. The condition onsets in adolescence and can advance rapidly causing irregular astigmatism and distorted vision. This can lead to the need of specialty contact lenses in order to see with functional vision and eventually to a corneal transplant at advanced stages. Luckily a new treatment called corneal cross-linking has been developed in recent years to stop this progressive loss of vision before it can disable our patients.
Over the past 3 years Dr. Stelzer was a clinical investigator involved in the FDA ACOS Avedro study for corneal cross-linking. In 2016 the FDA approved this procedure. Avedro is the first and only FDA approved therapeutic treatment for progressive keratoconus and post-refractive ectasia.
· Safety and effectiveness not established in pediatric patients below the age of 14 years
· Early keratoconus cases are better than moderate or late stage cones
· Progressive Keratoconus patients are ideal
· Central corneal thickness over 400 microns
· Minimal to no corneal scarring
· Patients with healthy immune systems taking no immunosuppressive agents
· No patientswho are pregnant or lactating
1. Corneal epithelial removal and 30 mins of riboflavin application (eye drops)
2. 30 mins of UV Irradiation
3. Bandage contact lens (worn for about 4-5 days to allow healing)
Post-Op Regimen and Follow-Up Schedule:
1. Antibiotic and steroid eye drops are used for the first few days-weeks. Preservative free artificial tears hourly for the first month
- 1 Day (followed daily for first 2-3 days)
- 4 Days (BCL Removal)
- 2 weeks
- 1 Month
- 3 Months
- 6 Months (if needed)
Keys for successful treatment:
1. Time is of the essence. Treat young early cones ASAP. Teenagers are ideal.
2. Some corneal flattening of 1-2 diopters may occur as result. This doesn’t generally improve vision and only stops ectasia progression.
3. The second eye can be treated after the first eye’s 1 Month follow-up
4. Contact lens wear can be resumed 1 Month after treatment
5. All patients diagnosed with keratoconus shouldn’t rub their eyes before or after the procedure.
If you or anyone you know has keratoconus or blurry vision, please call to schedule an exam with our eye doctor. Seeing an optometrist is crucial in determining if you have this eye condition and if you qualify for treatment.
