Ophthalmic Lubricants
Key Points
- Ophthalmic lubricants provide temporary relief of burning, irritation, and discomfort from dry eyes.
- Core agents are artificial tears (solution) and white petrolatum/mineral oil (ointment).
- Most products are OTC, so label-directed dosing and contamination prevention teaching are essential.
- Common adverse effects include transient burning, watery/itchy eyes, blurred vision, and photophobia.
- Do not continue use when eye pain, vision change, persistent redness, or worsening irritation occurs.
Class Overview
Ocular lubricants supplement or protect the tear film and reduce ocular-surface irritation from dryness or environmental exposure (for example wind and sun). Depending on formulation, they can reduce tear-film osmolarity and dilute inflammatory substances while replacing missing tear constituents.
Products are available as solutions, gels, emulsions, and ointments. Some formulations include additional components such as vasoconstrictors or antimicrobial ingredients, so clients should follow product-specific instructions carefully.
Common Agents and Typical Dosing
| Drug | Typical Adult Ophthalmic Dosing Pattern | Notes |
|---|---|---|
| Artificial tears (for example glycerin/propylene glycol) | 1-2 drops in affected eye(s) as needed | Do not use if solution is discolored or cloudy |
| White petrolatum/mineral oil ointment | About 1/4-inch ribbon inside lower eyelid as needed | Ointment can cause temporary blurred vision and eyelash stickiness |
Adverse Effects and Contraindications
- Ocular burning/stinging, watery or itchy eyes
- Blurred vision and photosensitivity
- Eye pain or redness with intolerance patterns
- Eyelash stickiness/crusting with ointment accumulation
- Contraindication: allergy to inactive ingredients in specific products
Nursing Assessment and Interventions
- Assess symptom severity and treatment response (relief of burning/irritation vs worsening pattern).
- In intubated, unconscious, or nonblinking clients, inspect eyes frequently and remove old lubricant gently with a damp cloth to prevent buildup/crusting.
- Clean periocular skin to support hygiene and reduce infection risk.
- Monitor for hypersensitivity cues, including rash, dizziness, breathing difficulty, or facial/tongue/throat swelling.
- Reinforce technique return-demonstration for safe instillation.
Client Education
- Avoid touching dropper or tube tip to eye, skin, or other surfaces.
- Use ordered/label dosing and do not double a missed dose.
- Stop the product and contact the prescriber for eye pain, vision change, persistent redness, or worsening irritation.
- Avoid driving or hazardous activity until vision clears after instillation.
- Seek reassessment if symptoms fail to improve.
