The summary describes a contact lens made of a specific material and manufacturing process, with no mention of AI or ML in its function or development.
Yes
The intended use of the device is for the correction of visual acuity, which improves a physical function (vision).
No
Explanation: The device is a contact lens intended for correcting visual acuity, which is a treatment, not a diagnostic function.
No
The device description clearly states it is a contact lens, which is a physical medical device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "for the correction of visual acuity." This is a therapeutic or corrective function, not a diagnostic one. IVDs are used to diagnose diseases or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease or its sequelae.
- Device Description: The description details the material composition and physical properties of a contact lens. This aligns with a medical device used for vision correction, not a diagnostic test.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing information for diagnosis.
Therefore, the Sunsoft (methafilcon A) Soft (Hydrophilic) Contact Lens, as described, is a medical device for vision correction, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
The Sunsoft (methafilcon A) Soft ( Hydrophilic) Contact Lens is a random copolymer of 2-hydroxyethylmetharcylate and methacrylic acid. When hydrated, the lens consists of 45% methafilcon A and 55% water by weight when immersed in normal saline. It is indicated for the correction of visual acuity.

Summary of Performance Studies
Biocompatibility, Physical/Optical Characteristics, and Manufacturing Process Validation studies were conducted.
- Biocompatibility: Cytotoxicity, acute systemic toxicity, and ocular irritation studies were conducted with samples of tinted lenses produced with the proposed static molding and lathing process. Results showed no evidence of cellular or systemic toxicity, or ocular irritation.
- Physical/Optical Characteristics: Light transmittance, refractive index, linear expansion, oxygen permeability, and tensile strength were determined in samples of tinted lenses produced by static and centrifugal molding. Lenses were of similar thickness and power, and comparison of data showed the lenses were equivalent in physical and optical characteristics.
- Manufacturing Process Validation: Two replicate production batches of three lens designs (toric, asphere, and sphere) were produced. Thirty samples per batch were evaluated for axis and cylinder power (toric), base curve (sphere and asphere), diameter, lens thickness, and dioptric power. All measurements were within specification. Evaluation of process capability for dioptric power resulted in Cok values of 1.2 or greater for all batches.

§ 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.

Trade Name
Sunsoft (methafilcon A) Soft (Hydrophilic) DW Contact Lens
Generic Name:
Soft Contact Lens
Equivalent Device:
Sunsoft (methafilcon A) Soft (Hydrophilic) Contact Lens
Description and Intended Use:
The Sunsoft (methafilcon A) Soft ( Hydrophilic) Contact Lens is a random copolymer of 2-hydroxyethylmetharcylate and methacrylic acid. When hydrated, the lens consists of 45% methafilcon A and 55% water by weight when immersed in normal saline. It is indicated for the correction of visual acuity.
Assessment Of Equivalence:
Biocompatibility
Cytotoxicity, acute systemic toxicity and ocular irritation studies were conducted with samples of tinted lenses produced with the proposed static molding and lathing process. Test results showed no evidence of cellular or systemic toxicity, or ocular irritation.
Physical/Optical Characteristics
Light transmittance, refractive index, linear expansion, oxygen permeability and tensile strength were determined in samples of tinted lenses produced by static and centrifugal molding. Lenses were of similar thickness and power. comparison of the data from this study showed that the lenses were equivalent in physical and optical characteristics.
Manufacturing Process Validation
Two replicate production batches of three lens designs, that is, toric, asphere and sphere, were produced using the proposed production method. Thirty samples per batch were evaluated for axis and cylinder power (toric) base curve (sphere and

asphere), diameter, lens thickness and dioptric power. All measurements were within specification. Evaluation of process capability for dioptric power resulted in Cok values of 1.2 or greater for all batches.
Conclusions
Biocompatibility studies of tinted lenses produced with the proposed manufacturing process showed no evidence of cellular or systemic toxicity, or ocular irritation. A comparative evaluation of this lens with lenses manufactured using the approved centrifugally molded/back lathed process showed that the two methods of production result in lenses that are equivalent in physical and optical characteristics. The static molding process is highly capable, as evidenced by a process validation study in which the manufacture of sphere and toric lens designs met all specifications of lenses manufactured by currently approved molding technology.
