I-Defence (5g), Night-Time Use

Description

Overview

I-Defence is a preservative-free lubricating eye drop formulation designed for immediate relief and long-lasting hydration of dry, irritated eyes. Ideal for patients experiencing mild to moderate dry eye symptoms, contact lens discomfort, or occasional eye irritation. The preservative-free format makes it safe for frequent use throughout the day without risk of preservative accumulation or toxicity — a critical feature for patients managing chronic dry eye.

About this product

Dry eye affects millions of Canadians — from those experiencing occasional seasonal dryness to patients with chronic dry eye disease. The challenge: many patients need to use artificial tears 4+ times daily, making preservative-free formulation essential to prevent chemical irritation that comes with chronic preservative exposure.

I-Defence meets this need with a preservative-free formula that lubricates and hydrates without the risk of toxicity from repeated chemical exposure.

Key Features
– Preservative-Free: Safe for frequent daily use (4+ times daily) without risk of preservative accumulation or epithelial damage
– Immediate Hydration: Fast-acting formula provides relief within seconds of application
– Long-Lasting Comfort: Extended relief duration allows spacing between doses
– Contact Lens Compatible: Can be used with contact lenses in place (verify lens material first)
– Natural Ingredients: Lubricating formula that mimics healthy tear composition
– Convenient Single-Use Vials Optional: Available in multi-dose preservative-free bottles for economy

How It Works

1. Apply: Instill 1-2 drops into the affected eye(s) as needed
2. Frequency: Use as needed for comfort, typically 4-6 times daily or more as directed by your eye care provider
3. Timing: Can be used multiple times daily without concern for preservative toxicity
4. With Contact Lenses: May be used with lenses in place, though removal and re-insertion often provides better comfort

Key benefits

• Preservative-free safety — eliminates risk of chemical irritation with frequent use
• Contact lens compatible — can be instilled with lenses in place (for most soft lenses)
• Fast relief — immediate hydration when eyes feel dry or irritated
• Extended comfort — longer duration of relief reduces frequency of dosing
• Cost-effective — preservative-free multi-dose bottles are more economical than single-use vials
• Suitable for all ages — gentle formula safe for children and seniors
• Works synergistically with other treatments — complements warm compresses, eyelid hygiene, and clinical dry eye therapies
• UDEI-recommended maintenance — ideal for between-visit maintenance when dry eye symptoms are controlled

Suggested use

For Mild Dry Eye:
– Use 4-6 times daily as needed for comfort
– Increase frequency if symptoms worsen

For Moderate Dry Eye Under Clinical Care:
– Use as directed by your UDEI or U Optical eye care provider
– Typically 6-8 times daily during active symptoms

For Contact Lens Wearers:
– Apply before or after contact lens insertion as needed
– Verify your specific lens material is compatible (most soft lenses are; some silicone hydrogel lenses may have restrictions — check product packaging)
– If contact lens comfort doesn’t improve, schedule an appointment at U Optical for lens reassessment

Precautions:
– Do not use if you have a known allergy to any ingredient
– If irritation increases after a few days of use, discontinue and consult your eye care provider
– Do not touch the tip of the bottle to your eye or eyelid (contamination risk)
– Close multi-dose bottles tightly and store at room temperature

Clinical backing

Recommended by:
U Dry Eye Institute (UDEI) — as first-line maintenance therapy for mild to moderate dry eye, and as supplemental lubrication alongside clinical treatments

Why UDEI clinicians recommend it:
Preservative-free lubricating drops are foundational in dry eye management because they provide safe, frequent hydration without chemical irritation. I-Defence’s formulation supports natural tear composition and is ideal for patients requiring multiple daily doses. UDEI recommends it as both standalone therapy for mild dry eye and as maintenance support during and after advanced treatments (IPL, LipiFlow).

Pairs well with

• Heated Eye Mask — Combine lubricating drops with daily warm compresses to address both tear quantity (drops) and meibomian gland function (heat)
• i-LID n LASH — Support eyelid hygiene alongside lubrication for comprehensive dry eye management
• Thealoz Duo — If I-Defence relief duration is insufficient, upgrade to a longer-lasting gel formulation for extended comfort
