Contact lenses and corneal shields.
Contact lens wear has been associated with a wide spectrum of corneal complications.  Disposable contact lenses have not eliminated the problem of corneal ulcers associated with extended-wear contact lenses. Rigid, gas-permeable extended-wear lenses may be considered as an acceptable alternative to extended wear of soft contact lenses. Collagen corneal shields are a clinical indicator of collagenase activity on the ocular surface and serve as a collagenase inhibitor.
