6 Carbomer Eye Gel Drops You Need to Know

Carbomer eye gel (also known as carbomer eye drops) is one of the most commonly used eye drops for the treatment of dry eyes. Carbomer is a gel-based eye lubricant, which has thicker consistency (viscosity) as compared to eye drops. In this post, I will discuss the availability of different brands of carbomer eye gels, their side effects, and the essential information about specific brands of carbomer eye gel products.

Where can I buy carbomer eye drops?

The most carbomer eye gel products are pharmacy-only medications, which means they’re available to buy only from pharmacies, including online chemists. Pharmacy-only medicines are kept away from the public and not available for self-selection. Carbomer eye drops are usually kept in the dispensary, which means customers need to ask about the product availability, should they wish to purchase it. Many of the discussed carbomer eye gel products are available from with some great savings for when multiple packs are bought at the same time. Links are provided throughout the post. 

Can you get carbomer eye drops on NHS?

Carbomer eye gel products can be prescribed by a GP, however, the general trend for prescribing in the UK is to buy products over the counter from a pharmacy rather than having it prescribed on NHS. When carbomer eye gel is prescribed by GP on a prescription, it is usually requested as a ‘generic’ product. This means a pharmacy can supply any carbomer brand, usually, the cheapest option is supplied to patients.

Dry eyes treatment recommendations

Lifestyle measures are among the first recommendations in the management of dry eyes, for example:

  • Reducing the time of contact lens wear or changing their type or lens solution
  • Increase blink time when working in front of computer screens or reading
  • Lowering computer screen below eye level
  • Reducing alcohol intake and avoiding cigarette smoke
  • Consideration of medication change that may cause a dry eye syndrome

Eye drops/eye gels are recommended when lifestyle measures failed to improve symptoms.

NICE guideline on the management of dry eyes does not recommend any specific brands of artificial tear products. However, it broadly suggests using eye drops during the daytime, and eye gels/ointments at night, before going to bed as these are more likely to cause temporary blurred vision (NICE, 2017).

Preservative-free formulations of eye drops/gels should be considered when patients are intolerant of preservative and suffer from moderate to severe dry eyes, which require more frequent administration eye drops/eye gels, for example, more than four times a day (ibid).

How does carbomer eye gel work?

Carbomer (chemical name: polyacrylic acid) forms a lubricating film rapidly over the eye (the conjunctiva and cornea). Lubrication time is prolonged due to the nature of carbomer. The retention time of carbomer in the eye is longer as compared to standard eye drops (eMC, 2017).

Carbomer eye drop products used in the management of dry eyes contain 2.0mg/g carbomer (0.2%).

How to use carbomer eye gel?

Carbomer eye gel is usually used 3-4 times a day. When prescribed, please follow the directions of your doctor.

How to instil carbomer eye gel?

Check product information leaflet before use. Also, check the expiry date before using carbomer eye gel. Then:

  • Wash your hands
  • Sit down or lie down and tilt your head backward
  • With one hand hold the gel vertically (you may want to control of the gel by making a fist)
  • Use second hand to pull your lower eyelid downwards.
  • Look upwards.
  • Insert one drop of the gel inside the lower eyelid by squeezing the tube. Care should be taken to avoid contact between the eye and the nozzle of the tube.
  • Blink a few times to spread the eye gel around the eye.
  • If present, excess of the eye gel can be wiped away from the eyelid.

Carbomer eye gel: common side effects

The most common side effect associated with the use of carbomer eye gel is blurred vision. Patients who drive or use operating machines should be aware of this possible side effect and wait until the vision clears before performing any of the tasks mentioned.

Other common side effects may include:

  • Eye irritation
  • Eye discomfort

Dry eyes: alternative treatment options

Patients who experience dry eyes have plenty of products to choose from. Other popular eye drops and eye gels for the management of dry eyes may contain the following active ingredients:


Carbomer eye gels are considered safe and effective in the management of dry eyes. Although there is no high-quality evidence to support carbomer eye gel above other formulations in the management of dry eyes, available information suggests that gel formulation of carbomer offers prolonged lubrication of the eye as compared to eye drops, which may provide better treatment. Patients who failed to respond to the treatment and patients who experience vision loss should see their GP. Any changes to the vision require an urgent appointment with a doctor.

Patients who experience temporary itchy, red and watery eyes, may be experiencing symptoms of hayfever. When in doubt speak to the pharmacist, who may recommend the best product. Management of watery & itchy eyes caused by hayfever include use of sodium cromoglicate eye drops and steroid and other nasal sprays.
