This page describes products and general information; it is not medical advice.
An Optilock wound dressing is a non-adhesive dressing with a super absorbent polymer core, sold by Medline, that turns wound fluid (exudate) into a gel and holds it in the core away from the wound. This page is for clinic staff, buyers and students who need to know how it is built, how the manufacturer describes it, and how it differs from older or simpler dressings.
What is an Optilock wound dressing?
Medline describes Optilock as “the optimal dressing for locking away exudate.” It is a super absorbent polymer core dressing that takes in wound fluid, including under compression, and is non-adhesive. Medline states that it does not stick to the wound or the skin around it, and that it adjusts its absorption to the amount of drainage. Medline also lists an at-home version of the product.
How is it built?
Medline’s product page lists three layers. Each does one job, which is the main difference from a plain gauze pad.
| Layer | What Medline says it does |
|---|---|
| Dispersion layer | Spreads exudate evenly and quickly transfers it into the core |
| Super absorbent core | Absorbs large amounts of exudate and converts it to a gel that is locked away from the wound |
| Blue protective backing | Helps protect clothing and sheets |
“Locking” refers to the gel: once fluid has become gel in the core, it is held there rather than sitting against the wound bed. Medline’s comparative performance claims (for example, against a silicone-faced foam) cite footnoted data that the catalog page does not show, so they are not repeated here.
Primary or secondary dressing: what do the terms mean?
Medline lists Optilock for use both as a primary dressing and as a secondary dressing. A primary dressing sits on the wound; a secondary dressing covers or secures another layer. The manufacturer’s catalog page gives the full list of indications for each role, and that list governs; this page does not restate it or recommend a dressing for any individual wound.
How does it compare with other dressing types?
Optilock and hydrophilic wound dressings
U.S. regulation (21 CFR 878.4018) defines a hydrophilic wound dressing as a sterile or non-sterile device intended to cover a wound and to absorb exudate, and places that class under general controls. Absorbing exudate is Optilock’s stated function, so it sits in the same general product family; this page does not state a regulatory classification for Optilock itself. For related absorbent products, see highly absorbent wound dressings and hydrophilic wound dressings.
Optilock and non-adherent dressings
Both are described as not sticking to the wound. A non-adherent dressing is primarily a contact surface; Optilock’s stated distinguishing feature is its super absorbent core. See what a non-adherent dressing is.
Labels and handling
Medline publishes directions for Optilock on its catalog pages and on the product package. Retailer descriptions can differ from the manufacturer’s, so the instructions on the package in hand are the reference. Dressing choice and application belong to a trained clinician.
Frequently asked questions
What is a wet-to-dry wound dressing?
Wet-to-dry is a traditional gauze dressing method that is used as a form of mechanical debridement, the removal of devitalized tissue. A review of wound debridement and cleansing lists debridement as surgical, mechanical (wet-to-dry gauze) or chemical (Rodeheaver, Ostomy Wound Manage 1999, PubMed PMID 10085978). A chart review of 202 home-care and health-maintenance-organization patients with open wounds found wet-to-dry dressings accounted for 42% of wound care orders, and that mechanical debridement was not clinically indicated in more than 78% of the wounds treated this way (Cowan and Stechmiller, Adv Skin Wound Care 2009, PubMed PMID 19935135). A 2026 retrospective cohort study of fasciotomy wounds after the 2023 Kahramanmaras earthquakes found dressing-related complications significantly higher with wet-to-dry dressings than with negative pressure wound therapy, with no significant difference in infection rate (Kazez et al., PubMed PMID 42261853). Those studies concerned clinical wound care, not Optilock. Optilock is a manufactured non-adhesive dressing with an absorbent polymer core, a different thing from a gauze method.
What is an Adaptic wound dressing?
Adaptic is a separate product with its own CASRAI guide: what Adaptic is. It is not the same product as Optilock.
Does Optilock stick to the wound?
Medline describes it as non-adhesive and states it does not stick to the wound or the skin around it.
