## Indications for use
The Acuity 100 (hexafocon A), Acuity 85 (oprifocon A), Acuity 58 (enflufocon B) and Acuity 18 (enflufocon A) Rigid Gas Permeable Contact Lenses are indicated for daily wear for the correction of refractive error (myopia, hyperopia, presbyopia and/or astigmatism) in aphakic and non-aphakic persons with non-diseased eyes. The lens may be prescribed in spherical and aspheric powers ranging from -20.00 D to +20.00 D for daily wear. The lenses may be prescribed for daily wear in otherwise non-diseased eyes that require a rigid contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive (e.g., LASIK) surgery. The lens may be disinfected using a chemical disinfection system only. The lenses may be stored in a multipurpose solution (BOSTON SIMPLUS or Menicon Unique pH) solution up to 30 days.
