2. γ-polyglutamate-based eye care product
1. Medical grade sodium γ-polyglutamate (γ-PGA) is a highly biocompatible biomaterial that has successfully passed various biocompatibility tests for medical devices. In October 2022, Vedan Biotech became the world's first company to obtain the US FDA Master File for Device (MAF) number for γ-PGA, allowing safe and reliable use of γ-PGA for the development of medical devices and related products. γ-PGA is a fully biodegradable natural biopolymer with exceptional hydrophilic water retention properties and high affinity for cations, making it highly suitable for developing medical devices such as wound dressings, dermal fillers, bone and joint lubricants, bone medical materials, and ophthalmic devices.
2. Vedan Biotech has conducted various experimental tests to demonstrate the alternative application of γ-PGA-based eye care product. Through these tests, it has been confirmed that γ-PGA-based eye drops can enhance tear secretion, alleviate dry eye symptoms, and reduce corneal damage. This product's uniqueness lies in its long-lasting protective effect without requiring frequent application.
