Device Description

The dimensions of DuraSoft® 3 and DuraSoft® 3 UV (phemfilcon A) Spherical and OptiFit Toric hydrophilic contact lenses in Clear, Colors, Complements, ColorBlends and Handling Tint are the same as approved in PMA 830037/S41 and K982344.

The lens material (phemfilcon A) is a hydrophilic copolymer of 2-hydroxyethyl methacrylate and 2-ethoxyethyl methacrylate. The DuraSoft® 3 UV (phemfilcon A) contact lenses are made by adding the UV absorber to the monomer mixture. The physical properties of the lenses are listed below. The light transmittance table has been added as approved for the Supplement No. 42 PMA P830037 and 510(k) K991550 (FreshLook Bifocal UV-absorbing (phemfilcon A) contact lenses). The data to support this table is available in Section X, Exhibit -3.

Regulation Number and Section

§ 886.5925 Soft (hydrophilic) contact lens.

(a)
Identification. A soft (hydrophilic) contact lens is a device intended to be worn directly against the cornea and adjacent limbal and scleral areas of the eye to correct vision conditions or act as a therapeutic bandage. The device is made of various polymer materials the main polymer molecules of which absorb or attract a certain volume (percentage) of water.(b)
Classification. (1) Class II if the device is intended for daily wear only.(2) Class III if the device is intended for extended wear.
(c)
Date PMA or notice of completion of a PDP is required. As of May 28, 1976, an approval under section 515 of the act is required before a device described in paragraph (b)(2) of this section may be commercially distributed. See § 886.3.
