There was an even apical clearance and a small kidney-shaped bubble positioned either inferiorly or at the temporal limbus. While coverage by the right upper eyelid is now quite adequate in blinks and during sleep, he still occasionally suffers dryness and epiphora, and he continues to use viscotears as a lubricant to the right eye. He will retain the lens in case this problem recurs. Within this framework, the potential advantages of contact lenses as a therapeutic device in cases of facial nerve palsy are their ability to provide a protective barrier, pain relief, an improvement in vision, the promotion of re-epithelialisation and the prevention of desiccation. As the lens is supported by the sclera, centration is independent of corneal topography and distortion.
Mechanical trauma is avoided as the lens vaults over the corneal surface.
Also, the lens acts as an ideal moisture chamber for the cornea. They seem to prefer non-fenestrated scleral lenses. However, if the practitioner has the skill to provide a small, mobile air bubble, which avoids unwanted visual and desiccation effects, the use of fenestrations is acceptable. Our patient, who was in this category, is a good example of their successful use. The use of soft bandage lenses in corneal disease.
