Device Description

Paraperm® EW (pasifocon C) rigid gas permeable contact lenses for daily wear are available as lathe cut or molded firm contact lenses with spherical, aspheric, bifocal or toric anterior and/or posterior; or, bitoric surfaces in clear and tinted versions. Paraperm® EW rigid gas permeable contact lenses for extended wear are available as lathe cut or molded firm contact lenses with spherical or aspheric anterior or posterior surfaces in clear and tinted versions. The posterior curve is selected so as to properly fit an individual eye and the anterior curve is selected to provide the necessary optical power to correct refractive error. A peripheral curve system on the posterior surface allows tear exchange between the lens and the cornea. The Paraperm® EW rigid gas permeable contact lens material is a thermoset copolymer derived from siloxane and methylmethacrylate. The Paraperm® EW rigid gas permeable tinted lenses offer a handling aid for locating the lens.

GMDN Terms

Code	Name	Definition	Implantable	Status
47840	Rigid-gas-permeable corrective contact lens, daily-wear, non-customized	A prefabricated (non-customized) rigid ophthalmic lens intended to be worn directly against the cornea of the eye to correct refractive vision conditions (e.g., myopia, hyperopia, astigmatism, presbyopia); it is designed to be removed prior to sleeping each night. The device is made of various materials (e.g., cellulose acetate butyrate, polyacrylate-silicone, silicone elastomers) whose main polymer molecules generally do not absorb or attract water but permit diffusion of oxygen (O2) to the ocular surface. This is a reusable device.	No	Active
47944	Rigid-gas-permeable corrective contact lens, extended-wear	A rigid ophthalmic lens intended to be worn directly against the cornea of the eye to correct refractive vision conditions (e.g., myopia, hyperopia, astigmatism, presbyopia); it is designed for continuous overnight wear for up to 7, 15, or 30 consecutive nights. The device is made of various materials (e.g., cellulose acetate butyrate, polyacrylate-silicone, silicone elastomers) whose main polymer molecules generally do not absorb or attract water but permit diffusion of oxygen (O2) to the ocular surface. The lens may last for years and is a reusable device.	No	Active
