The BostonSight® Specialty Lenses (roflufocon D, roflufocon E, tisilfocon A, hexafocon B, oprifocon A, fluoroxyfocon A) for daily wear are indicated for the correction of refractive ametropia (myopia, astigmatism, and presbyopia) in aphakic and non-aphakic persons with non-diseased eyes. The lenses may be prescribed in otherwise nondiseased eyes that require a gas permeable contact lens for the management of irregular corneal conditions such as keratoconus, pellucid marginal degeneration, or following penetrating keratoplasty or refractive surgery. Furthermore, eyes suffering from certain ocular surface disorders may benefit from the physical protection, aqueous hydrated environment, and the saline bath provided by scleral lens designs. The BostonSight Specialty Lenses for daily wear in the scleral lens designs are indicated for therapeutic use in eyes with ocular surface disease including, but not limited to, ocular Graft-versus-Host disease, Siögren's syndrome, dry eve syndrome and Filamentary Kerattis, 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. Additionally, the BostonSight Specialty Lenses for daily wear in the scleral lens designs are indicated for therapeutic use for the management of irregular and distorted corneal surfaces. Common causes of corneal distorion include, but are not limited to, corneal infections, trauma, tractions as a result of scar formation secondary to refractive surgery (e.g. LASIK or radial keratotomy) or corneal transplantation. Causes may also include corneal degeneration (e.g. keratoconus, keratoglobus, pellucid marginal degeneration, Salzmann's nodular degeneration) and corneal dystrophy (e.g., lattice dystrophy, granular corneal dystrophy, Reis-Bucklers dystrophy). When prescribed for therapeutic use for a distorted cornea or ocular surface disease, the BostonSight Specialty Scleral Lenses for daily wear may concurrently provide correction of refractive error. Eye care practitioners may prescribe the lenses for frequent/planned replacement wear, with cleaning, disinfection and scheduled replacement. When prescribed for frequent/planned replacement wear the lens may be cleaned and disinfected using a chemical (not heat) lens care system.

The BostonSight® Specialty Lenses for daily wear are lathe cut from one of the following hydrophobic, FDA Group #3 fluoro-silicone acrylate rigid gas permeable (RGP) lens materials: roflufocon D, roflufocon E, tisilfocon A, hexafocon B, oprifocon A, fluoroxyfocon A. The lenses fabricated from roflufocon D, roflufocon E, tisilfocon A, hexafocon B, fluoroxyfocon A are available with or without Tangible® Hydra-PEG coating. The lenses fabricated from oprifocon A are not available with Tangible® Hydra-PEG. The lenses may be shipped "dry" or "wet" in a polypropylene contact lens case. When shipped "wet", the lenses are packaged non-sterile in Boston SIMPLUS® Multi-Action Solution.
