Presentation Transcript

  1. Management of Keratoconus • Eyeglasses/soft contact lenses • Rigid gas permeable (RGP) contact lenses • Intracorneal rings • Corneal cross-linking • Corneal transplant

  2. Eyeglasses/soft contact lenses • For early stage of KC • Mild astigmatism/myopia • Have a limited role in improving vision

  3. Rigid gas permeable (RGP) contact lenses • primary option for correcting KC vision • masks the underlying irregular cornea • functions as the new refractive surface

  4. 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

  5. Corneal cross-linking • Not a cure but prevents progression of KC • Glasses or contact lenses may still be needed

  6. 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
