Approval Order Statement  
Approval for DilightTM (roflufocon E) Overnight Orthokeratology Contact Lens. The lenses are indicated for use in the reduction of myopic refractive error in non-diseased eyes. The lens is indicated for overnight wear for the temporary reduction of myopia up to 4.00 diopters (manifest spherical equivalent) in eyes with astigmatism up to 1.50 diopters.

Failure to do so can affect daily activities (e.g., night driving), cause visual fluctuations, and changes in intended correction.
