Shop by Ingredient and Mechanism
Sometimes you do not want a category, you want a molecule. This is the cross-reference: the active ingredients and mechanisms behind the shelf, what each one does, and where to find it, so you can match a product to the exact problem in front of you.
Key Takeaways
- Mechanism comes first. Pick the action you want on the surface, then the ingredient, then the product.
- Preservative status is the single most important attribute on a frequently dosed product.
- HA holds water, lipids rebuild the oily layer, HOCl lowers bacterial load, and terpinen-4-ol targets Demodex. Four mechanisms cover most decisions.
- Omega and carotenoids are the nutritional mechanisms: support and risk reduction, taken daily and long term.
- Use this page to translate a finding into an ingredient, then send the product through RescueLink or pull it from your shelf.
Quick Answer
Decide the mechanism you want first. For surface hydration, reach for hyaluronate in a preservative-free base. For an unstable, oily-deficient film, reach for a lipid or emulsion. For lid bacterial load, reach for HOCl; for Demodex, terpinen-4-ol. For long-term support, omega in re-esterified triglyceride form and macular carotenoids. The table below maps each mechanism to where it lives on the shelf, with example products you can stock or route.
The Core Mechanisms
Most product decisions come down to a handful of actions on the surface and lid.
Hydration
Hyaluronate (HA)
Binds and holds water on the surface for longer retention between blinks.
Stability
Lipid and Emulsion
Rebuilds the oily layer so the film stops evaporating in evaporative and MGD patterns.
Tolerability
Preservative-Free (PF)
Removes the preservative insult on frequently dosed or compromised surfaces.
Lid bacteria
Hypochlorous (HOCl)
Lowers lid bacterial load and inflammation with minimal sting.
Demodex
Terpinen-4-ol
The tea tree component that targets Demodex and the collarettes that follow.
Nutrition
Omega and Carotenoids
Daily, long-term support: omega for the surface, carotenoids for the macula.
Ingredient to Action to Where It Lives
A cross-reference. Example products are ones we reach for; confirm each on its current label.
| Ingredient or mechanism | What it does | Where to find it |
|---|---|---|
| Sodium hyaluronate (HA) | Holds water on the surface for longer retention | Eye drops, e.g. iVIZIA |
| Lipid or emulsion | Rebuilds the oily layer, slows evaporation | Eye drops, e.g. Refresh Optive Mega-3, Systane Complete |
| Preservative-free base | Removes preservative insult for frequent dosing | PF multidose, PF vials |
| Ointment, overnight | Maximum contact time while eyes are closed | Gels and ointments, e.g. HYLO Night |
| Hypochlorous acid (HOCl) | Lowers lid bacterial load and inflammation | HOCl cleaners, e.g. Avenova, OCuSOFT HypoChlor |
| Terpinen-4-ol (tea tree) | Targets Demodex and cylindrical collarettes | Tea tree cleansers, e.g. Cliradex |
| Omega-3 (rTG form) | Daily surface support as an adjunct | Omega vitamins, e.g. PRN DE3 |
| Carotenoids (lutein, zeaxanthin) | Macular pigment support and AMD risk reduction | Macular vitamins |
These mechanisms map to the standard categories of dry eye and lid management: tear replacement and retention, lipid layer support, preservative reduction, lid hygiene, and nutritional adjuncts (TFOS DEWS III). Confirm active ingredients and concentrations on each product's current label.
Send the Exact Ingredient to the Patient
Once you know the mechanism, RescueLink sends the matching product to the patient by text or email in under 60 seconds, with one-tap ordering, same-day shipping, and optional auto-ship. The recommending relationship stays with your practice.
DER Clinical Pearl
When two products look interchangeable, compare them at the ingredient level. The preservative status, the lipid content, and the omega form tell you more about how a product will perform than the brand on the front. Mechanism first, brand second.
Frequently Asked Questions
Why shop by mechanism instead of brand?
Because the mechanism predicts performance. Two brands with the same active ingredient and base behave alike; two products in the same category with different mechanisms do not.
What is the single most important attribute on a drop?
Preservative status, especially for frequent dosers and compromised surfaces. It is the variable most likely to keep a surface inflamed.
HA or lipid, how do I choose?
Match the failure point. Low retention and dryness favor HA; an unstable, oily-deficient film favors a lipid or emulsion. Mixed patients often use both.
What does terpinen-4-ol do?
It is the tea tree component that targets Demodex. Plain wipes without it will not clear the mites.
Why does omega oil form matter?
Re-esterified triglyceride omega tends to absorb better than ethyl ester, so the form affects how much usable omega the patient gets.
Where do carotenoids fit?
They are the macular mechanism: lutein, zeaxanthin, and meso-zeaxanthin for pigment support and AMD risk reduction, not a dry eye treatment.
How do I get the matched product to the patient?
Pull it from your shelf or send it through RescueLink. The patient orders in one tap with same-day shipping, and the refill stays in your practice. Ordering help is at providers@dryeyerescue.com or (561) 468-8747.
