These lenses replace the natural shape of cornea and are therefore used in cases of keratoconus. Initially they were used for high refractive errors and astigmatism.
These types of lenses are the most commonly used in clinical practice. Increased oxygen permeability, wetability and overall comfort are the reasons behind its popularity
They are prescribed in cases of astigmatism where the curvature of cornea is irregular in one particular axis.
