Moderate to severe dry eye – a promising indication for scleral lenses

Summary The space between the scleral lens and the ocular surface is called the reservoir and can be filled with aqueous agents, thus allowing for a permanent hydration of the cornea. This property is a major advantage of scleral lenses in dry eye. Furthermore, the lenses protect the epithelium from lid frictions and may also promote corneal epithelial growth. Finally, scleral lenses decrease sensory nerve stimulation, decreasing symptoms, even in moderate dry eye patients.
