Ocular lubricant (artificial tears)

Carbomer: uses, side effects & precautions

Also known as Viscotears, GelTears, Liquivisc, Liposic.

This information is for general guidance only and does not constitute medical advice. Always consult a qualified healthcare professional for personal medical concerns. In an emergency, call your local emergency number.

What it is used for

  • Dry eyes
  • Eye discomfort, grittiness or burning from reduced tear production
  • Tear-film support in conditions causing dry eye

How it works

Carbomer is a thick, water-based gel that mimics natural tears, coating the surface of the eye to keep it moist and reduce the gritty, dry feeling. It does not treat an underlying cause but soothes and protects the eye surface.

How it is taken

Comes as a clear eye gel (and similar lubricant drops). A small amount is placed into the affected eye(s). Wash your hands first and keep the nozzle from touching your eye. Use as often as needed for comfort within the limits your pharmacist or label gives. Apply other eye medicines first and the gel last, spacing them apart, and ask a pharmacist about contact lenses.

No doses here on purpose. The right strength and schedule depend on you — only a doctor or pharmacist should set them. Always follow your prescription and the label.

Common side effects

  • Temporary blurred or sticky vision after applying
  • Mild stinging on application
  • Eyelids feeling slightly tacky

Serious effects — get help

  • Signs of an allergic reaction such as facial swelling, severe rash or breathing difficulty
  • Worsening eye pain, redness or vision changes (which may signal a different problem needing assessment)

If a reaction is severe — for example trouble breathing, swelling of the face or throat, or collapse — go to the nearest emergency room now or call your local emergency number. Do not wait for an online consultation.

Interactions to watch

  • Other eye drops (apply the gel last and space applications apart)
  • Contact lenses (many gels are not for use with lenses; check the label)

Who should take care

  • Persistent dry eye should be assessed by a clinician to find the cause
  • If your vision is affected, wait until it clears before driving
  • Discard after the opened-bottle period on the label
  • Tell a pharmacist if symptoms do not improve

Frequently asked questions

How often can I use artificial tears?
Many lubricants can be used as often as needed for comfort, but follow your specific product's label and ask a pharmacist if you find yourself needing them very frequently.
Why does my vision blur after the gel?
The gel is thick and briefly clouds vision before it spreads. Wait until it clears before driving. Some people prefer to use it at bedtime.
Will it cure my dry eye?
It relieves symptoms but does not fix the underlying cause. If dry eye is ongoing, see a clinician to investigate why.
Can I use it with contact lenses?
Many thicker gels are not designed for use with lenses. Check the label and ask your pharmacist for a lens-friendly option if needed.
Is Carbomer safe to take?
For most people it is safe when taken exactly as a doctor or pharmacist advises and as printed on the label. Tell your clinician about your other medicines and health conditions, and seek urgent care for any serious reaction.
