Hyaluronic acid (HA) is commonly used in ophthalmology for its biological safety and water retention properties. It is often utilized in intravitreal injections, dry eye treatment, and contact lenses. HA in contact lenses can improve wearer comfort and gradually release to the eyes to treat dry eye.
Hyaluronic acid (HA) is a glycosaminoglycan that was first isolated and identified from the vitreous body of a bull's eye. HA is ubiquitous in the soft connective tissues of animals and therefore has high tissue compatibility for use in medication. Because of HA's biological safety and water retention properties, it has many ophthalmology-related applications, such as in intravitreal injection, dry eye treatment, and contact lenses. Due to its broad range of applications, the identification and quantification of HA is a critical topic. This review article discusses current methods for analyzing HA. Contact lenses have become a widely used medical device, with HA commonly used as an additive to their production material, surface coating, and multipurpose solution. HA molecules on contact lenses retain moisture and increase the wearer's comfort. HA absorbed by contact lenses can also gradually release to the anterior segment of the eyes to treat dry eye. This review discusses applications of HA in ophthalmology.
