We CAIR about Keratoconus.
What is CAIRS?
Many patients with keratoconus struggle with reduced best corrected visual acuity or may be contact lens intolerant. While cross-linking only stops progression it does not improve vision. Fortunately, there are other solutions to improve a patients best possible corrected vision. One such option is CAIRS (Corneal Allogenic Intrastromal Ring Segments). This minimally invasive procedure involves implanting corneal donor tissue segments into the cornea to flatten the cone and regularise the cornea. As a result, it can allow for a more stable refraction, improved contact lens tolerance, and in some cases may even achieve functional vision with spectacles alone. It is different from PMMA rings (Intacts/Kerra-ring), having no risk of extrusion, it is biocompatible and therefore safer and more effective.
Who is a suitable candidate for CAIRS?
- BCVA less than 0.5 (6/12 or worse)
- Contact lens intolerance
- Patients wishing to avoid a full-thickness corneal transplant
- Previously cross-linked patients
- Previous corneal transplant patient
