The document describes a standard soft contact lens made from polymacon, focusing on its material properties and intended use for vision correction. There is no mention of any computational or analytical capabilities that would suggest the use of AI or ML.
Yes
The device is indicated for the correction of visual acuity, which is a therapeutic function addressing a medical condition (myopia, hyperopia, astigmatism).
No
Explanation: This device, a soft contact lens, is indicated for the "correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia." Its purpose is to correct vision, not to diagnose a medical condition.
No
The device description clearly states it is a physical contact lens made from polymacon, a material that becomes soft and pliable when hydrated. It describes the physical properties and manufacturing process of a tangible medical device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVDs are used to examine specimens from the human body. The provided text describes a contact lens, which is a medical device placed on the eye to correct vision. It does not involve the analysis of biological samples like blood, urine, or tissue.
- The intended use is for correcting visual acuity. This is a therapeutic and corrective function, not a diagnostic one.
- The device description focuses on the physical properties and function of the contact lens. It doesn't mention any diagnostic tests or procedures.
Therefore, based on the provided information, the ALDEN CLASSIC contact lens is a medical device, but not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The ALDEN CLASSIC (polymacon) Spherical Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia. The lens may be worn by persons who exhibit refractive astigmatism of 1.50 diopters or less where the astigmatism does not interfere with visual acuity.
The ALDEN CLASSIC (polymacon) Toric Soft Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and/or possesses refractive astigmatism not exceeding 10 Diopters.

Device Description
The ALDEN CLASSIC (polymacon) Soft (Spherical & Toric) Daily Wear Contact lenses are fabricated from polymacon, which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution.
In the hydrated state, the lens conforms to the curvature of the eye covering the cornea and extending slightly beyond the limbus forming a colorless, transparent optical surface. The (polymacon) soft hydrophilic contact lens has a spherical back surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eve. If the lens dries out, it will become hard and appear somewhat warped; however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 38% water by weight. The physical properties of the lens are:
Refractive Index: 1.52 (dry) 1.43 (hydrated)
Light Transmission: greater than 95% T
Water Content: 38 %
Specific Gravity: 1.28 (dry) 1.18 (hydrated)
Oxygen Permeability: 9 X 10-11 Fatt Units (cm2/sec)(ml O2/ml x mm Hg @ 35° C), (revised Fatt method)

§ 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.

Substantial Equivalence:
The device will be manufactured according to specified process controls and a quality assurance program. The device will undergo manufacturing, packaging and sterilization procedures similar to devices currently marketed and distributed by Alden Optical Laboratories. The established safety profile (preclinical toxicology and manufacturing/chemistry data) of the device is equivalent to BENZ-38, 510(k)# K961103. Being similar with respect to indications for use, materials, physical construction and safety & effectiveness to the predicate devices, this meets the requirements per section 510(k) of the act regarding substantial equivalence and does not raise different questions of safety and effectiveness than the predicate devices identified above.
The following matrix illustrates that the production method, lens function and material of the ALDEN CLASSIC (polymacon) Soft (Spherical & Toric) Daily Wear Contact Lens (Clear & Tinted, Lath-cut from Lens Blank), are substantially equivalent to the predicate devices. In addition, the water content, polymer, DK value, refractive index, specific gravity, and light transmission are as well substantially equivalent.

Dear Mr. Dalsing:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
