Keratoconus, a non-inflammatory corneal ectasia, is characterized by progressive corneal thinning and apical protrusions. Due to the cornea ectasia, optic problems can occur and the contact lens plays very important role in the correction. Increased irregular astigmatism due to the corneal ectasia, specialized CL designs are required to improve the vision.With recent advances in materials and design technology, treatment of Keratoconus with contact lens have developed greatly and there are various types of contact lenses are available. In this review, we will know about the wide variety of contact lens such as rigid and soft lenses, hybrid lenses, scleral lenses, piggyback contact lens (PBCL), softtoric lenses. In this article, we discuss about selection of the contact lens depending on the type of Keratoconus and fitting technique of different types of contact lenses.
