Read the full statement (202 words)
The SDJMASTERVISION (fluoroxyfocon 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 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 SDJMASTERVISION (fluoroxyfocon A) Rigid Gas Permeable Contact Lenses are also indicated
for therapeutic use in eyes with ocular surface disease (e.g. ocular Graft-versus-Host disease,
Sjogren’s syndrome, dry eye syndrome and Filamentary Keratitis), limbal stem cell deficiency (e.g.
Stevens-Johnson syndrome, chemical radiation and thermal burns), disorders of the skin (e.g. atopy,
ectodermal dysplasia), neurotrophic keratitis (e.g. Herpes simplex, Herpes zoster, Familial
Dysautonomia), and corneal exposure (e.g. anatomic, paralytic) that might benefit from the presence
of an expanded tear reservoir and protection against an adverse environment. When prescribed for
therapeutic use for a distorted cornea or ocular surface disease, the lens may concurrently provide
correction of refractive error.
The SDJMASTERVISION (fluoroxyfocon A) Rigid Gas Permeable Contact Lenses may be cleaned
and disinfected using a chemical (not heat) lens care system.
