Keratoconus is a non-inflammatory corneal dystrophy characterized by progressive steepening and thinning of the paracentral cornea, resulting in high irregular astigmatism. This dystrophy typically manifests during adolescence and progresses until the age of 40 years . Keratoconus develops more aggressively in children and adolescents than in adults. Moreover, a younger age of diagnosis is associated with corneal opacities and rapid progression to advanced-stage disease.


Management options for keratoconus include contact lenses, corneal crosslinking, intrastromal ring segments (INTACS), and corneal transplant. Contact lenses manage the blurry vision from irregular astigmatism in keratoconus. Contact lenses create a smooth refractive surface over the keratoconus eye thus making vision much clearer. This article will review the contact lens option for keratoconus.  




Corneal Rigid Gas Permeable Lenses (RGP) for Keratoconus 


These lenses are small diameter (less than 12.00mm) rigid lenses that rest on the corneal surface. Tears fill in the space between the cornea and the lens which help correct for vision. 




















Scleral Lenses for Keratoconus 


Large diameter rigid lens that vaults completely over the cornea and rests on the scleral conjunctival shape. During wear, these lenses are filled with preservative free saline which rests between the cornea and the back surface of the scleral lens. 






















Hybrid Lenses for Keratoconus


This lens is a rigid gas permeable lens fused to a soft contact lens skirt. 




















Soft Toric Specialty Lenses for Keratoconus 


This soft lens is made to fit the eye shape of patients who have keratoconus. The slightly thicker center helps correct for vision in keratoconus.
