Difference between Sodium Hyaluronate Eye Drops 0.1 and 0.3

The main difference between sodium hyaluronate eye drops 0.1 and 0.3 lies in their concentration. Sodium hyaluronate eye drops with a concentration of 0.3 have higher viscosity and stronger moisturizing effect, making them suitable for patients with moderate to severe dry eye syndrome; A concentration of 0.1 is more suitable for mild dry eyes or daily eye moisturizing.

Sodium hyaluronate eye drops with a concentration of 0.1 belong to low concentration preparations, with an osmotic pressure close to natural tears. After use, it can quickly form a protective film on the ocular surface, relieving mild dryness caused by excessive eye use and dry environment. This type of eye drop has a refreshing texture and no obvious foreign body sensation after application, making it suitable for daily use by workers who wear contact lenses or electronic screens for a long time. However, due to its short moisturizing duration, it needs to be repeated multiple times a day to maintain its effectiveness.

Sodium hyaluronate eye drops with a concentration of 0.3 contain higher molecular weight sodium hyaluronate, which significantly improves the viscoelasticity of the solution and can form a more durable protective layer on the corneal surface. This concentration is particularly suitable for patients with severe insufficient tear secretion and corneal epithelial damage, and has a significant effect on relieving moderate to severe dry eye symptoms such as burning sensation and foreign body sensation. Due to its high viscosity, there may be a brief blurring of vision after dripping. It is recommended to use it at night or take a short rest with your eyes closed after use. When choosing eye drops, it is necessary to determine the degree of dryness. For mild symptoms, using a 0.1 concentration can avoid the burden caused by high viscosity preparations, while for corneal injury patients, it is recommended to use a 0.3 concentration preparation under the guidance of a doctor. Daily eye care can be combined with physical therapies such as hot compress and blink training to avoid prolonged exposure to air-conditioned rooms or strong wind environments. If persistent eye redness or pain occurs, seek medical attention promptly to diagnose other ocular surface diseases.
