A scleral contact lens lies on the sclera, not the cornea, which differs from a rigid gas permeable (RGP) contact lens, and has shown successful clinical outcomes in patients unable to tolerate glasses or RGP contact lenses because of a severely deformed cornea. In addition, a scleral lens forms a tear film between the cornea and contact lens that stabilizes the ocular surface and could be a useful therapeutic option. The mini-scleral contact lens is a useful therapeutic option for visual improvement and symptom control in patients with corneal abnormalities such as keratoconus, corneal opacity, ocular surface disease, and irregular corneal astigmatism.
