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.
