A recently granted patent (Publication Number: US12012238B2) discloses a novel packaging system for ophthalmic devices. The system includes a sealed container containing unused ophthalmic devices immersed in an aqueous packaging solution. This solution comprises ectoine or an ophthalmologically acceptable ectoine derivative, along with a modified glycosaminoglycan. The aqueous solution meets specific criteria, including an osmolality of at least 150 mOsm/kg and a pH range of 6 to 9. The modified glycosaminoglycan is a reaction product of different glycosaminoglycans and crosslinking agents, providing a unique composition for preserving ophthalmic devices.
Furthermore, the patent details variations in the packaging system, such as the use of specific glycosaminoglycans like hyaluronic acid and chondroitin sulfate, as well as different ectoine derivatives like L-ectoine and hydroxyectoine. The aqueous packaging solution contains precise concentrations of ectoine or its derivatives and the modified glycosaminoglycan to ensure stability and efficacy. Additionally, the modified glycosaminoglycan can be further enhanced with glycophospholipid polymers or grafted glycosaminoglycan polymers, providing versatility in the packaging system. Overall, the patent highlights a comprehensive approach to packaging ophthalmic devices, focusing on maintaining their integrity and functionality through innovative formulations and compositions.
