What is Keratoconus?

Keratoconus is a bilateral non-inflammatory disorder that causes progressive thinning of the cornea. Keratoconus is a genetic condition, but ocular allergies, eye rubbing, and connective tissue disorder may enhance progression. The treatment is determined by the stage of the condition. Early keratoconus or keratoconus suspect patients can be managed with spectacles, contact lenses, and routine eye examinations. If the condition is still progressive, progression should be inhibited, this is done by doing corneal cross-linking. Intra-stroma corneal rings, laser vision correction, and scleral contact lenses can all be used as part of the treatment plan. If the keratoconus is already in an advanced stage a corneal transplant will be considered.
