"What are the Differences Between Sodium Hyaluronate Eye Drops and Polyethylene Glycol Eye Drops?"

Sodium hyaluronate eye drops and polyethylene glycol eye drops are both commonly used ophthalmic medications. The difference between the two lies in their different compositions and functions. Detailed analysis is as follows:

1. Different Drug Compositions:

The main component of sodium hyaluronate eye drops is sodium hyaluronate, which belongs to linear polysaccharides. In contrast, polyethylene glycol eye drops are primarily composed of polyethylene glycol and propylene glycol, a high-molecular-weight polymer with film-forming and hydrophilic properties.

2. Different Functions:

Sodium hyaluronate eye drops are primarily used to treat xerophthalmia, mechanical damage to the corneal epithelium, and have a water-retaining effect. On the other hand, polyethylene glycol eye drops are intended to temporarily alleviate discomforts such as stinging and burning sensations caused by dry eyes, primarily serving a lubricating role.

Therefore, when using eye drops, it is crucial to strictly follow medical advice and administer medications according to their functions, avoiding self-medication. Furthermore, those allergic to the drug components are prohibited from using them. If eye irritation, allergic reactions, or other adverse effects occur after medication, discontinue use immediately and seek medical attention promptly.
