In ophthalmology, hyaluronic acid (HA) products are primarily used as ophthalmic viscoelastic devices and eye drops. Ophthalmic viscoelastic devices are mainly used in various eye surgeries, including glaucoma and cataract surgeries, while eye drops are primarily used for treating dry eye syndrome and corneal burns.
1. Hyaluronic Acid for Eye Surgery
Application Scenarios
Principle
Glaucoma Surgery
Prevents the formation of excessive scarring post-surgery, maintains a functional bleb, improves early and long-term control of intraocular pressure, and reduces complications such as shallow anterior chambers.
Cataract Surgery
Minimizes damage to intraocular tissues caused by surgical instruments and artificial lenses during the procedure.
Corneal Laser Surgery
Reduces post-operative pain and corneal haze after refractive corneal ablation and helps avoid complications related to the creation of corneal flaps in laser in-situ keratomileusis (LASIK).
Eye Trauma Surgery
Maintains corneal transparency, prevents vitreous extrusion and minor anterior chamber bleeding, and prevents posterior iris adhesion.
2. Hyaluronic Acid For Eye Drops
Application Scenarios
Principle
Treating Dry Eye Syndrome
Interacts with the corneal surface and tear film to stabilize the tear film, providing moisture, lubrication, and protection, and relieving eye discomfort.
Treating Corneal Burns
Functions as a large molecule glycosaminoglycan within the intercellular matrix of various tissues, aiding in cell adhesion and osmotic regulation, and promotes corneal epithelial cell proliferation and wound healing through a subepithelial basal membrane effect.
For Contact Lens Wearers
Applied as eye drops before or after wearing contact lenses to alleviate dryness and eye fatigue, and reduces adverse reactions caused by preservatives in the drops.
