There are many reasons to promote corneal gas permeable (GP) lenses as a modality in your specialty contact lens practice. For patients with regular corneas, soft lenses have become increasingly popular as parameters expand and toric designs improve. The optics of a corneal GP lens are likely going to beat out the best soft contact lens designs available in the case of significant astigmatism, however.
For patients with irregular corneas, scleral lenses have become a practitioner favorite due to their smooth transition and adaptation period and high rate of success when it comes to vision and comfort.

This modality is associated with fewer health risks and is less complicated than scleral lenses.
