The Adypi Etafilcon A Hydrophilic Contact Lens was cleared by the FDA via the PMA pathway on November 20, 1989. It is manufactured by Hanita Contact Lens Laboratory and classified as a Class 2 device.
What It Is
The Adypi Etafilcon A Hydrophilic Contact Lens is a soft contact lens designed for vision correction. It is made from etafilcon A, a hydrophilic material that enhances comfort and wettability.
Clinical Applications
This contact lens is commonly used in patients requiring vision correction for conditions like myopia. It is also applied in cosmetic scenarios, such as in cases of microcornea.
Evidence Summary
The available literature includes 10 studies, comprising various study types such as RCTs and case series, published between 2008 and 2025. These studies investigate aspects like wettability, antimicrobial properties, and cosmetic applications.
Reported Outcomes
Published studies report that the Adypi Etafilcon A lens improves wettability and retains antimicrobial properties when coated with Mel4. It is noninferior to silicone hydrogel lenses concerning hypoxic stress and has potential applications in myopia control.
Safety Profile
Reported complications include discomfort and microbial infections, which are common issues with contact lens wear. However, the addition of antimicrobial coatings may mitigate some of these risks.
Evidence Limitations
The evidence is limited by a lack of large-scale, long-term studies. Further research is needed to explore the full potential of atropine delivery via these lenses and to confirm long-term safety and efficacy.
