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
