Lakrimont (Carbomer 980)

Lakrimont, containing Carbomer 980, is employed in ophthalmic products that require viscosity enhancement. It supports several ocular care applications:

• Dry Eye Syndrome: improves tear film stability and reduces ocular dryness.
• Ocular Surface Irritation: provides a protective lubricating layer to soothe irritated eyes.
• Post‑Surgical Eye Care: maintains moisture and comfort after ocular procedures.
• Contact Lens Wear: assists in maintaining lens hydration and comfort.
• Allergic Conjunctivitis: helps to reduce symptom severity by stabilizing the tear film.

• Carbomer 980 is a high‑molecular‑weight acrylic acid polymer that swells in aqueous media to form a gel matrix. When incorporated into eye drop solutions, it increases viscosity by creating a three‑dimensional network that entraps water molecules, thereby prolonging residence time on the ocular surface and enhancing lubrication without interacting with ocular receptors.

Carbomer 980 may cause local ocular reactions when used in eye drop formulations.

Common Side Effects

• Stinging or burning sensation upon instillation.
• Transient blurred vision.
• Mild eye redness.
• Temporary tearing.
• Mild ocular irritation.
• Sensation of foreign body in the eye.

Serious or Rare Side Effects

• Allergic hypersensitivity reaction (e.g., swelling, itching).
• Corneal epithelial damage.
• Severe conjunctival inflammation.
• Vision loss (very rare).
• Persistent ocular pain.
• Development of ocular infection secondary to irritation.

When using Lakrimont, consider the following precautions:

• Allergy Assessment: verify no known hypersensitivity to carbomers.
• Contact Lens Use: avoid wearing contact lenses immediately after administration.
• Ocular Monitoring: observe for persistent irritation or worsening symptoms.
• Concomitant Medications: separate instillation times from other eye drops to prevent dilution.
• Pediatric Use: use only under professional supervision.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Carbomer 980 may interact with other ophthalmic agents, influencing comfort or efficacy.

Major Interactions (Avoid)

• Preservative‑rich eye drops: may increase irritation when combined.
• Surfactant‑containing solutions: can destabilize the polymer gel matrix.

Moderate Interactions (Monitor Closely)

• Other viscosity‑enhancing agents: may cause excessive thickening.
• Systemic antihistamines: may reduce tear production, affecting overall lubrication.
• Topical corticosteroids: monitor for altered healing response.
• Anticholinergic eye drops: assess for additive drying effects.
• Ocular anesthetics: watch for heightened sensitivity.
