- Title
Scleral lenses in the management of exposure/neurotrophic keratopathy in patients with cranial nerve palsy.

- Abstract
Scleral lenses are increasingly being recognized as a viable option for management of exposure keratopathy. Unlike more aggressive surgical interventions, the lenses can provide complete protection of the ocular surface without compromising visual clarity or restricting visual field. Preservation of corneal epithelial integrity is of utmost importance when lid function is compromised or absent. The fluid reservoir between the posterior surface of a scleral lens and the anterior corneal surface provides continuous hydration of the corneal epithelium and allows for healing of any epithelial defects. Furthermore, the lens itself protects fragile epithelial tissue from shear forces arising from lid movement over the cornea during the blink. Preservation of visual function is also important for these patients. Those who suffer from decreased vision due to irregularity of a desiccated ocular surface frequently note improvement in visual function with scleral lens wear, because the lens provides a smooth optical surface and neutralizes any corneal irregularity. This presentation will review and summarize visual and ocular outcomes of scleral lens therapy for management of exposure keratopathy at the Mayo Clinic.
