Intrastromal Corneal Rings

Surgery Duration:

  • Approximately 20 minutes.

What Does It Involve?

  • Intrastromal corneal rings are used to treat corneal deformation caused by keratoconus.
  • The procedure involves inserting rings between the layers of the corneal stroma to flatten and stabilize the corneal cone.

When Is It Carried Out?

  • Indicated for cases of keratoconus where contact lenses can no longer correct the condition.
  • Suitable only if the corneal thickness allows for the insertion of the rings.

Prior Examination:

  • A comprehensive eye examination and corneal topography are required.

Surgery:

  • The surgery takes between 15 and 20 minutes.
  • Performed under topical anaesthesia on an outpatient basis.

Recovery and Results:

  • The effect of the rings on corneal deformation takes several months to manifest.
  • Visual recovery is typically slow.

Risks:

  • No significant risks are associated with the procedure.

Associated Pathologies:

  • Keratoconus
  • Myopia
  • Astigmatism
