Lacryvisc (Carbomer 974p)

• Lacryvisc is used as an ocular lubricant that addresses dry eye and supports post‑operative eye care.
• Dry eye syndrome: provides sustained lubrication to relieve discomfort and visual disturbance.
• Post‑operative eye care: helps maintain moisture and comfort after ocular surgery.
• Contact lens wear: offers temporary relief of lens‑related dryness when recommended by an eye care professional.

• Carbomer 974p is a high‑molecular‑weight polymer that swells upon contact with aqueous tear fluid, forming a gel‑like matrix. This increases the viscosity of the ophthalmic solution, prolonging its residence time on the corneal surface and creating a stable, moist environment that protects and lubricates the eye.

Lacryvisc may cause ocular reactions, ranging from mild irritation to rare serious events.

Common Side Effects

• Transient stinging or burning sensation upon instillation
• Temporary blurred vision
• Mild conjunctival redness

Serious or Rare Side Effects

• Allergic conjunctivitis with swelling
• Corneal epithelial defect
• Persistent eye pain or vision loss

• When using Lacryvisc, consider the following safety measures.
• Allergy screening: verify patient has no known hypersensitivity to Carbomer 974p or formulation components.
• Infection control: avoid use in eyes with active bacterial or viral infection unless directed.
• Contact lens use: remove lenses before instillation and re‑insert after the drop has been absorbed.
• Pregnancy and lactation: use only if benefit outweighs potential risk, under professional advice.
• Eye surgery: follow surgeon’s postoperative regimen; do not substitute without guidance.
• Store at room temperature: keep in original container, protect from moisture and direct light.

Lacryvisc may interact with other ophthalmic products; monitor patients accordingly.

Major Interactions (Avoid)

• Concurrent use with ophthalmic solutions containing preservatives that may increase irritation.
• Use with anti‑inflammatory eye drops that could alter viscosity and drug distribution.
• Combination with ocular antibiotics that require a clear visual field may be compromised.

Moderate Interactions (Monitor Closely)

• Simultaneous administration with other lubricating drops may affect overall tear film stability.
• Use with contact lens solutions may cause temporary lens discomfort.
• Co‑administration with intra‑ocular pressure‑lowering agents should be monitored for any change in drug absorption.
