What is it indicated for?

The Unicon Hydrogel (Hioxifilcon A) Soft (Hydrophilic) Contact Lens is indicated for the correction of ametropia (myopia and hyperopia) in aphakic and non-aphakic persons with non-diseased eyes and 6.00 diopters (D) or less of astigmatism.

Eye Care Professionals may prescribe the lenses either for single-use disposable wear or frequent/planned replacement wear with cleaning, disinfection and scheduled replacement. When prescribed for daily disposable wear, the lens is to be discarded after each removal. When prescribed for frequent/planned replacement wear, the lens may be cleaned and disinfected using a chemical disinfection system only.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
