Management of Keratoconus

• Eyeglasses/soft contact lenses• Rigid gas permeable (RGP) contact lenses • Intracorneal rings• Corneal cross-linking• Corneal transplant

Eyeglasses/soft contact lenses

• For early stage of KC• Mild astigmatism/myopia• Have a limited role in improving vision

Rigid gas permeable (RGP) contact lenses

• primary option for correcting KC vision

• masks the underlying irregular cornea• functions as the new refractive surface

Intracorneal rings

• Semi-circular rings inserted into the mid layer of the cornea

• Flatten the cornea change the shape and location of the cone

• Eliminates some or all of the irregularities caused by keratoconus

• Glasses or contact lenses may still be needed

Corneal cross-linking

• Not a cure but prevents progression of KC• Glasses or contact lenses may still be needed

Corneal transplant

• May be done when:– cornea becomes dangerously thin– sufficient visual acuity to meet the individual’s

needs can no longer be achieved by contact lenses• steepening of the cornea• scarring • lens intolerance irregular cornea can no longer be

fitted with a contact lens
