Artificial Tears

Artificial tears are lubricating eye drops that supplement natural tears. They're used for dry eye syndrome and to protect the eye surface in many neuro-ophthalmic conditions.

Common Uses

• Dry eye syndrome
• Thyroid eye disease—exposure
• After Botox injections
• Blepharospasm
• Bell's palsy—poor lid closure
• Post-surgical care

Types of Artificial Tears

By Viscosity

• Thin/watery—less blur, shorter lasting
• Medium—good balance
• Thick/gel—longer lasting, more blur

By Preservative Status

• Preserved—OK for occasional use
• Preservative-free—better for frequent use (>4x/day)

Specialized Formulations

• Lipid-containing—for evaporative dry eye
• Hyaluronic acid—enhanced lubrication
• Osmoprotectants—protect cells

How to Use

• Wash hands before use
• One drop per eye
• Close eyes gently after instillation
• Wait 5 minutes between different eye drops
• Use as often as needed (preservative-free)

When to Use Preservative-Free

• Using more than 4 times daily
• Sensitive eyes
• Contact lens wear
• After eye surgery
• Chronic use

Tips for Best Effect

• Use regularly, not just when symptomatic
• Room humidifier may help
• Avoid air blowing directly on eyes
• Warm compresses for meibomian gland dysfunction
• Consider omega-3 supplements

When Artificial Tears Aren't Enough

• Prescription drops (cyclosporine, lifitegrast)
• Punctal plugs (block tear drainage)
• Moisture chamber glasses
• See ophthalmologist for evaluation
