The contact lens can be used for gonioscopy ; for the correction of ametropias, especially in cases of optical keratoconus ; for the correction of astigmatism after corneal transplantation; in cases of monocular aphakia, and for protection of the globe in cases of trichiasis, distichiasis, lagophthalmos and entropion.
