The summary describes a standard contact lens with color additives and UV protection, with no mention of AI or ML technology in its design, function, or intended use.
Yes.
The device is indicated for the correction of refractive ametropia (myopia and hyperopia), which is a physiological condition, thereby making it a therapeutic device.
No
The device is a contact lens intended to correct refractive ametropia and/or alter eye color, not to diagnose a medical condition.
No
The device is a physical contact lens made of specific materials and containing color additives, not a software program.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health. This information is used for diagnosis, monitoring, or screening.
- Device Function: The Largan U38 Color Contact Lens is a medical device that is placed on the eye. Its function is to correct vision and/or alter the appearance of the eye. It does not analyze any biological samples from the body.
- Intended Use: The intended use clearly states it's for correcting refractive errors and/or enhancing eye color. This is a direct interaction with the body, not an analysis of a sample.
Therefore, based on the provided information and the definition of an IVD, this contact lens is not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The Largan U38 Color (Polymacon) Daily Wear Soft (hydrophilic) Contact Lens is a daily wear soft contact lens indicated for daily wear to enhance or alter the apparent color of the eye and/or for the correction of refractive ametropia (myopia and hyperopia) in phakic or non-aphakic persons with non-diseased eyes who exhibit refractive astigmatism of 1.00D or less where the astigmatism does not interfere with visual acuity.
Eye care practitioners may prescribe the lens for either single-use disposable wear, or for frequent/planned replacement wear, with cleaning, disinfection, and scheduled replacement. When prescribed for single-use disposable wear, the lens is to be discarded after each removal, therefore no cleaning or disinfecting is required. When prescribed for frequent replacement, the lens may be disinfected using a chemical disinfection system only.
