Preservative‑free solutions are eye drops or saline products that do not contain chemical preservatives used to inhibit bacterial growth in multi‑dose bottles. They are designed to be gentler on the ocular surface.
Forms and Uses
These products are commonly supplied in single‑use vials or special multi‑dose containers that keep contents sterile mechanically. They are often recommended for people with sensitive eyes, frequent drop use, or contact lens wear.
- Reduce the risk of preservative‑related irritation or allergy
- Particularly useful in moderate to severe dry eye needing regular lubrication
- Single‑use vials must be discarded after opening
- Some are suitable for use with contact lenses; check the label
Considerations
Preservative‑free options may be more expensive but can improve comfort and tolerance of long‑term treatment. Choice should be guided by an eye care professional.
- Ideal where drops are needed more than four times a day
- Patients with ocular surface disease often benefit from these formulations
- Storage and expiry instructions should be followed carefully
- Do not share vials with others, even if single‑use
