Ophthalmic viscoelastic injector: Overview, Uses and Top Manufacturer Company

Introduction

Ophthalmic viscoelastic injector is a sterile medical device used to deliver an ophthalmic viscoelastic device (OVD) into the eye during surgery or selected procedures. OVDs are gel-like solutions designed to help maintain space, stabilize tissues, and support visualization—most commonly in anterior segment surgery such as cataract operations.

In day-to-day hospital operations, this small piece of hospital equipment can have outsized impact: it touches sterile workflow, surgical efficiency, traceability (lot and expiry documentation), patient safety (sterility and correct product selection), and cost control (high-volume single-use consumables).

This article explains what an Ophthalmic viscoelastic injector is, where it fits clinically, how it is typically set up and used, and how teams reduce risks—from pre-use checks to troubleshooting and infection prevention. It also provides a practical overview of manufacturers, vendors, and a country-by-country snapshot of global market dynamics relevant to procurement and service planning.

What is Ophthalmic viscoelastic injector and why do we use it?

An Ophthalmic viscoelastic injector is a clinical device that pushes a sterile viscoelastic material through a small cannula (a thin, blunt tube) into the anterior chamber or other surgical spaces in the eye. In many workflows, the injector is essentially a sterile syringe system (often prefilled with OVD) designed to deliver a controlled amount with minimal contamination risk.

What problem does it solve?

Ophthalmic surgery is performed in a confined, delicate space where tissues can be easily injured and where visibility is critical. Viscoelastic materials are used to:

• Maintain or create space (so instruments and implants can be introduced safely).
• Stabilize tissues (for example, supporting the iris or capsule during manipulation).
• Coat and protect sensitive structures (notably corneal endothelium, depending on the OVD type and technique).
• Improve visualization by clearing small folds and helping maintain a formed chamber.

The Ophthalmic viscoelastic injector is the delivery tool that makes these goals practical at the operating microscope. Without a reliable injector system, OVD delivery can become inconsistent, slow, or unsafe (for example, due to air injection, contamination, or sudden surges).

Common clinical settings

You will most often see an Ophthalmic viscoelastic injector used in:

• Cataract surgery (including phacoemulsification steps and intraocular lens implantation preparation).
• Corneal procedures (varies by procedure type and surgeon preference).
• Glaucoma procedures where anterior chamber stability is needed (varies by technique).
• Combined anterior segment cases where multiple implants or devices are introduced.

Settings include hospital operating rooms (ORs), ambulatory surgery centers (ASCs), and dedicated eye hospitals. In some regions, high-volume cataract programs rely heavily on standardized injector kits to streamline turnover.

Key benefits for patient care and workflow (general)

Benefits can include:

• More controlled delivery of a viscous material through a small-bore cannula.
• Reduced handling steps when using prefilled systems, which can support sterility.
• Better consistency in dose awareness (through syringe graduations and standardized volumes).
• Faster, more predictable setup for scrub teams when device choices are standardized.

The degree of these benefits varies by manufacturer, OVD type, and local workflow design.

Plain-language mechanism of action

Mechanically, the Ophthalmic viscoelastic injector works like this:

1. A plunger is advanced by hand (or by a mechanical assist in some designs).
2. The force pushes the viscoelastic material out of the syringe barrel.
3. The material flows through a cannula tip into the surgical space.

Because OVDs can be highly viscous, the injector must allow controlled force application. A key safety concept is that resistance can change quickly—if the cannula is obstructed, force builds; when the obstruction clears, flow can surge. That is why secure connections and slow, deliberate injection technique matter.

How OVD categories influence injector “feel”

Clinicians often describe OVDs by behavior (for example, “cohesive” vs “dispersive”). Without making clinical claims, it’s useful operationally to understand that:

• Some OVDs tend to be more “gel-like” and may come out as a bolus.
• Others are more “coating” and may feel different during injection.
• Temperature, storage conditions, and dwell time can change viscosity (varies by manufacturer).

These differences affect injection force, the risk of sudden flow, and cannula choice—so injector handling is part of procedural planning.

How medical students and trainees typically encounter this device

Learners usually meet the Ophthalmic viscoelastic injector in three ways:

• Observation in the OR: Watching how the scrub nurse prepares the device, how the surgeon primes and injects, and how communication happens during critical moments (capsulorhexis, lens implantation, etc.).
• Wet-lab or simulation: Practicing syringe control, avoiding air bubbles, and learning safe hand-offs within a sterile field.
• Post-case debriefing: Understanding how viscoelastic choice and injection technique interact with visualization, tissue behavior, and time.

For trainees, the “technology lesson” is often less about electronics and more about human factors: controlled force, secure connectors, tip control, and sterile handling under time pressure.

When should I use Ophthalmic viscoelastic injector (and when should I not)?

Use decisions should always be made under appropriate clinical supervision and local protocols. The points below are general and informational, not medical advice.

Appropriate use cases (typical)

An Ophthalmic viscoelastic injector is typically used when the procedural plan includes OVD placement to:

• Form or maintain the anterior chamber during intraocular manipulation.
• Protect ocular tissues during energy delivery or instrument passage.
• Create working space for implant insertion or tissue dissection.
• Support visualization and stability during delicate steps.

In practice, the “use case” is often defined by the OVD product selected, because many OVDs are supplied as prefilled sterile syringes intended to be injected via a dedicated cannula.

When it may not be suitable

Situations where an Ophthalmic viscoelastic injector may not be suitable include:

• Compromised sterility: Packaging damage, wet pack, missing seals, or unclear sterility indicators.
• Expired or unknown product: Expired device/OVD, missing lot number, or traceability gaps.
• Wrong product for the planned step: Using an unintended OVD type or concentration can create workflow issues; selection should follow surgeon preference and facility protocol.
• Device incompatibility: Mismatched connectors, cannula type not fitting securely, or incompatibility with the incision strategy (varies by technique and manufacturer).
• Single-use re-use risk: Reusing a single-use injector or cannula is generally not appropriate and creates infection-control and performance risks; always follow the manufacturer’s Instructions for Use (IFU).

Safety cautions and contraindications (general, non-patient-specific)

Because this is a delivery device, many “contraindications” are tied to:

• The OVD formulation (contraindications vary by manufacturer and labeling).
• Material compatibility (for example, latex concerns if applicable—varies by manufacturer).
• Mechanical integrity (cracks, plunger defects, loose fittings).

General cautions include:

• Avoid injecting if the cannula position is uncertain.
• Avoid forcing the plunger against high resistance without reassessing.
• Treat any unexpected resistance change as a potential occlusion/clearance event.
• Do not attempt off-label assembly (mixing components from different systems) unless facility policy and manufacturer guidance support compatibility.

Emphasize clinical judgment and supervision

Even when the device is simple, correct use depends on:

• Case selection and surgical plan.
• Viscoelastic choice and timing.
• Team coordination under the microscope.

For students and new staff, the safest learning approach is supervised practice, consistent device standardization, and a low threshold to ask for a pause when something feels wrong (resistance, air, questionable sterility).

What do I need before starting?

Preparation for an Ophthalmic viscoelastic injector is less about plugging in equipment and more about sterile readiness, correct product selection, and traceability. High-performing eye units treat these injectors like other critical consumables: standardized, checked, and documented.

Required setup, environment, and accessories

Common prerequisites include:

• A sterile procedure environment: Typically an OR or dedicated ophthalmic procedure room with appropriate sterile workflow.
• Sterile field and standard OR supplies: Drapes, sterile gloves, sterile basin if used, sharps container, and instrument table setup.
• The OVD and its delivery components: Often a prefilled syringe plus a sterile cannula; sometimes the cannula is integrated, sometimes separate (varies by manufacturer).
• Microscope-based workflow: Because the injection is performed under high magnification, hand-off technique and tip control are central to success.

Accessories may include:

• Cannula of a specific gauge, angulation, and tip design (varies by surgeon preference and manufacturer).
• Caps or protective sleeves for the tip to maintain sterility until use.
• If a reusable mechanical injector handle is used (less common), any required cleaning/sterilization tray and assembly tools per IFU.

Training and competency expectations

Competency typically covers:

• Sterile handling (opening, presenting, and passing the device without contamination).
• Identifying key labeling elements (product name, volume, lot number, expiry date).
• Priming technique to minimize air (as directed by IFU and surgeon preference).
• Recognizing abnormal resistance and knowing when to stop and escalate.

Hospitals often integrate this into:

• OR onboarding checklists.
• Ophthalmology-specific scrub training.
• Annual competency validation (especially in high-volume cataract services).

Pre-use checks and documentation

A practical pre-use checklist usually includes:

• Verify correct product and intended OVD type per case plan.
• Confirm packaging integrity and sterility indicators (if present).
• Confirm expiry date and legibility of lot number.
• Inspect the syringe barrel and plunger for cracks, misalignment, or leakage.
• Verify cannula packaging integrity and correct type.
• Confirm the connector is secure (Luer lock or other design; varies by manufacturer).
• Document traceability: many facilities record lot/expiry in the operative record or supply tracking system (requirements vary by country and facility policy).

If your facility uses Unique Device Identification (UDI) scanning, ensure the barcode is scannable before opening whenever possible.

Operational prerequisites: commissioning, maintenance readiness, consumables, policies

Most disposable Ophthalmic viscoelastic injector systems have minimal commissioning needs, but operations still matter:

• Standardization: Limit the number of injector/cannula variants to reduce errors and training burden.
• Par levels and forecasting: Cataract programs can be high-throughput; stock-outs can stop lists.
• Storage conditions: Follow IFU for temperature and light exposure; storage requirements vary by manufacturer.
• Waste handling: Plan for sharps and contaminated plastics; follow local regulations.
• If reusable components exist: Ensure sterilization capacity, validated cycles, and instrument tracking readiness.

Roles and responsibilities (clinician vs. biomedical engineering vs. procurement)

A clear RACI-style division prevents “ownership gaps”:

• Surgeon/clinician: Confirms indication, selects OVD type, performs injection, and addresses intraoperative issues.
• Scrub nurse/technologist: Maintains sterility, prepares and primes per protocol, and ensures correct hand-off.
• Circulating nurse: Verifies documentation, supports time-out processes, and manages supply availability.
• Biomedical engineering/clinical engineering: Typically limited involvement for fully disposable injectors, but important if reusable injector handles are used (maintenance, inspection criteria, and IFU adherence).
• Procurement/supply chain: Vendor qualification, contract terms, shelf-life management, lot recall readiness, and standardization efforts.

How do I use it correctly (basic operation)?

Exact steps vary by model and by whether the injector is prefilled or assembled from components. The workflow below focuses on common, broadly applicable steps and safety principles.

Basic step-by-step workflow (common pattern)

1. Confirm the correct item before opening – Match the product to the preference card or surgeon request. – Check expiry date, lot number, and packaging integrity. – If multiple OVDs are in the room, physically separate them to reduce selection errors.

2. Open the sterile packaging correctly – Use aseptic technique to peel and present contents onto the sterile field. – Avoid touching the cannula tip or any part that will be sterile-to-eye.

3. Assemble the system (if not pre-assembled) – Attach the cannula to the syringe using the intended connector. – Ensure a secure fit; loose connections can detach under high injection force.

4. Prime the injector (as directed by IFU and local protocol) – Remove the protective cap from the cannula when ready to prime. – Express a small amount of OVD to remove air and confirm patency. – Keep the tip oriented safely away from the patient and sterile field edges.

5. Maintain sterility until the moment of use – If there is a delay, recap with the provided sterile cap if permitted by IFU. – Protect the tip from contact with drapes, gloves, or non-sterile surfaces.

6. Hand-off to the surgeon – Pass the syringe in a way that protects the cannula tip and avoids accidental plunger depression. – Confirm verbally: product identity, cannula type, and readiness if this is your local practice.

7. Injection under visualization – The surgeon introduces the cannula and injects slowly and deliberately. – The goal is controlled delivery; sudden plunger movements can cause rapid flow changes.

8. Intraoperative adjustments – Additional OVD may be requested at different steps; keep track of which product is being used. – If the cannula becomes occluded or bent, replacement may be safer than forcing.

9. Post-use handling – Place the used syringe/cannula immediately into sharps or the designated contaminated instrument pathway. – Never place an uncapped cannula on the field in a way that risks needlestick injury.

10. Documentation – Record product used, lot number, expiry, and quantity if required. – Document any device issues or unusual resistance events per facility policy.

Setup, calibration, and “settings” (what applies, what may not)

Many Ophthalmic viscoelastic injector systems are fully manual and have:

• No electronic calibration.
• No programmable settings.
• Only syringe graduations and the tactile feel of injection.

Some systems may include mechanical assists or dedicated injector handles (varies by manufacturer). If your device has a reusable handle or a rate-control mechanism:

• Follow IFU for assembly order and pre-use checks.
• Confirm smooth plunger travel before approaching the eye.
• Perform any manufacturer-recommended functional checks (often a simple patency and connector integrity check).

Typical “controls” and what they mean

Even without electronics, operators still have “controls”:

• Plunger force: More force generally increases flow, but not linearly (viscosity and cannula gauge matter).
• Plunger travel: Indicates approximate volume delivered (be cautious of parallax and partial depressions).
• Cannula angle and depth: Changes flow direction and risk of tissue contact.
• Cannula gauge and length: Influence resistance; selection varies by surgeon and procedure.

The universal principle is slow, controlled injection with constant visual confirmation.

How do I keep the patient safe?

Patient safety with an Ophthalmic viscoelastic injector is mostly about preventing avoidable harm: contamination, wrong product use, unintended air injection, mechanical trauma, and process failures that delay care.

Safety practices that matter every case

• Sterility is non-negotiable: The injector is intended to enter a surgical wound. Any doubt about contamination should trigger replacement, not improvisation.
• Right product, right eye, right time: In busy lists, OVD syringes can look similar. Use labeling checks and clear separation on the sterile table.
• Secure connections: High resistance is common with viscous materials; a loose cannula can detach and create a sudden uncontrolled event.
• Control air: Air bubbles can be introduced during assembly or priming. Follow IFU and local technique to minimize air and confirm flow before use.
• Avoid forcing against resistance: If resistance is unexpectedly high, reassess. Forcing increases risk of sudden surge when occlusion clears.

Monitoring and situational awareness (team-based)

Unlike monitor-based devices, this medical equipment does not generate physiologic alarms. Safety relies on:

• The surgeon’s view and tactile feedback.
• The scrub team’s readiness to provide a replacement cannula/syringe quickly.
• Clear communication: “resistance,” “blocked cannula,” “new syringe requested,” and confirmation of product identity.

In teaching environments, narrating these cues helps trainees learn what “normal” feels like.

Alarm handling and human factors (when alarms exist, and when they don’t)

Most manual injectors have no alarms. If your facility uses an assisted injector mechanism that includes alerts (for example, occlusion detection), alarm behavior and response steps vary by manufacturer. General principles apply:

• Treat occlusion or error alerts as prompts to pause, not push harder.
• Confirm that the correct consumables are being used with that system.
• If the device behaves unexpectedly, switch to a backup method per protocol rather than troubleshooting over the open eye.

Human factors to plan for:

• Gloved grip and wet surfaces: Syringes can slip; use a stable hand position and avoid accidental plunger depression.
• Look-alike packaging: Reduce mix-ups through color coding, shelf segregation, and standardized preference cards.
• Time pressure: High-volume cataract lists can increase error risk; build in micro-pauses for checks.

Risk controls hospitals can implement

• Standardize to a small number of injector/cannula SKUs.
• Use two-person verification for high-risk look-alike items where feasible.
• Implement lot traceability (scanning or manual documentation).
• Maintain an “open pack” policy (what to do if a device is opened but not used).
• Encourage incident reporting for device failures or near misses without blame, so procurement and quality teams can act.

Labeling checks that support safety

Before opening (ideal) or immediately after opening (if necessary), confirm:

• Product name and intended use (OVD vs other ophthalmic syringe products).
• Volume and concentration information (varies by manufacturer).
• Sterility status and packaging integrity.
• Lot number and expiry date.
• Any labeled storage requirements and warnings.

If anything is unclear or not legible, replace the device and quarantine the questionable pack per facility policy.

How do I interpret the output?

An Ophthalmic viscoelastic injector usually does not produce a digital “output” like a monitor. Interpretation is based on physical cues and clinical visualization, with any numeric information coming from syringe markings or device indicators (if present).

Types of outputs or feedback you may have

• Syringe graduations: Approximate volume delivered by plunger position.
• Tactile resistance: The “feel” of flow through the cannula, which changes with viscosity, temperature, cannula gauge, and occlusion.
• Visual response under the microscope: Chamber formation, tissue coating, and space maintenance.
• Mechanical indicators (some designs): Plunger stops, clicks, or controlled travel mechanisms (varies by manufacturer).
• Electronic displays (less common): If a powered injector mechanism is used, it may show delivered volume or rate; features vary by manufacturer and model.

How clinicians typically interpret what they see

Interpretation is qualitative and procedure-specific, for example:

• “Is the chamber formed and stable?”
• “Is the OVD where it needs to be?”
• “Is visibility adequate for the next step?”
• “Is injection smooth and controlled without sudden surges?”

For trainees, a key learning point is that the same plunger movement can result in different flow depending on resistance, so observation and feel matter as much as markings.

Common pitfalls and limitations

• Parallax and partial depression: Syringe markings can be misread if viewed at an angle or if the plunger is not aligned.
• Hidden air: Small air bubbles can be missed until injection begins; priming technique matters.
• Temperature effects: Viscosity can change with temperature; storage outside IFU ranges can alter injection force.
• Occlusion artifacts: A blocked cannula may suddenly clear, making delivered volume unpredictable.
• Clinical correlation is required: The “right amount” is not a number alone; it depends on the surgical step and visualization, guided by the surgeon and protocol.

What if something goes wrong?

When an issue occurs with an Ophthalmic viscoelastic injector, the safest approach is usually to pause, maintain sterility, and switch to a backup device rather than “fixing” a questionable system over the patient.

A practical troubleshooting checklist

If there is no flow or minimal flow:

• Confirm the protective cap is removed from the cannula.
• Check that the cannula is not bent, kinked, or blocked.
• Verify the connector is fully seated and secure.
• Gently attempt priming away from the patient (if appropriate and allowed by workflow).
• If resistance remains abnormal, replace the cannula/syringe rather than forcing.

If there is sudden loss of resistance (unexpected surge risk):

• Stop advancing the plunger immediately.
• Reassess cannula position and stability.
• Communicate clearly to the team; prepare a replacement device if needed.

If there is leakage at the connector:

• Stop use; leakage suggests poor connection or device defect.
• Replace the system; do not try to “tighten” a contaminated or leaking interface over the field.

If you suspect contamination:

• Discard and replace.
• Treat it as a safety event; follow local incident reporting and quarantine rules.

If the wrong product is opened or presented:

• Do not use it “to avoid waste.”
• Replace with the correct product and document per policy.

When to stop use immediately

Stop and replace the device if:

• Packaging was compromised or sterility is in doubt.
• The cannula detaches or the connection is unstable.
• The syringe cracks, plunger binds, or leakage is seen.
• Resistance is abnormal and does not resolve with simple checks.
• There is any uncertainty about correct product identity.

When to escalate to biomedical engineering or the manufacturer

Escalation pathways differ by facility, but typical triggers include:

• Repeated failures with the same lot number or shipment.
• Suspected manufacturing defect (cracked barrels, misfitting connectors, unusual plunger behavior).
• Performance concerns in a reusable injector handle (if used), including wear, sticking, or incomplete sterilization indicators.

Biomedical engineering may assess reusable components and reprocessing workflows. Procurement and quality teams typically coordinate communication with the manufacturer and manage any field safety notices or recalls.

Documentation and safety reporting expectations (general)

Good operational practice includes:

• Documenting device identity (lot/expiry) and the nature of the problem.
• Saving packaging (when policy allows) for investigation.
• Reporting near misses, not just adverse outcomes, to support system improvement.
• Quarantining remaining stock from the same lot if a systemic defect is suspected, pending review.

Infection control and cleaning of Ophthalmic viscoelastic injector

Infection prevention for an Ophthalmic viscoelastic injector starts with a simple question: is the device single-use disposable, or does it have reusable parts? The answer is “varies by manufacturer,” and the IFU should be treated as the primary authority.

Cleaning principles (what’s universal)

• Maintain sterility until point of use.
• Do not reprocess single-use components unless the IFU and local regulations explicitly allow it.
• Prevent cross-contamination by immediate, correct disposal or transport in closed containers.
• Keep sharps safety central: cannulas should be managed like other sharp instruments.

Disinfection vs. sterilization (general)

• Disinfection reduces microbial load and is typically used for non-critical surfaces or equipment that does not enter sterile tissue.
• Sterilization aims to eliminate all microorganisms and is required for devices that enter sterile tissue or the eye.

Most disposable Ophthalmic viscoelastic injector systems arrive sterile and are discarded after use. If a reusable injector handle exists, it generally requires sterilization, not just disinfection—exact requirements vary by IFU.

High-touch points and contamination risks

Even with disposable systems, contamination risk can come from:

• Cannula tip contact with gloves, drapes, or table edges.
• Handling during assembly (touching the sterile connector or tip).
• Recapping practices that bring the cap into contact with contaminated surfaces.
• Misplacement on the instrument table where it can be bumped or inadvertently depressed.

If reusable components exist, high-touch points include the handle grip, plunger mechanism, and any joints where bioburden can accumulate.

Example cleaning workflow (non-brand-specific)

For a single-use Ophthalmic viscoelastic injector:

• Use once within the sterile case workflow.
• Immediately dispose into sharps (if cannula attached) or contaminated waste per policy.
• Do not attempt to flush or clean; this is not a validated process for most single-use devices.

For a reusable handle with disposable sterile cartridges (if applicable):

• Remove and discard the disposable cartridge and cannula as regulated waste.
• Transport the reusable handle in a closed container to decontamination.
• Follow IFU for disassembly, brushing/flush steps (if lumens exist), detergent type, rinse quality, drying method, and sterilization cycle.
• Document reprocessing in instrument tracking systems where used.

Always prioritize IFU and local infection prevention policy

Because materials, tolerances, and validated reprocessing methods differ, do not generalize one product’s cleaning method to another. Your infection prevention team and sterile processing department (SPD) should be involved in onboarding any reusable Ophthalmic viscoelastic injector components.

Medical Device Companies & OEMs

In procurement discussions, “manufacturer” and “OEM” are related but not identical concepts:

• A manufacturer is the company that markets the finished medical device under its name and is responsible for regulatory compliance, labeling, and post-market surveillance obligations (requirements vary by jurisdiction).
• An OEM (Original Equipment Manufacturer) may design or produce components or finished goods that are then marketed by another company (sometimes called private labeling). OEM relationships can exist for syringes, cannulas, connectors, and packaging.

Why OEM relationships matter to hospitals

OEM arrangements can influence:

• Consistency of component quality (connectors, cannula tolerances, plunger smoothness).
• Supply continuity (single-source components can be a vulnerability).
• Service and complaint pathways (who investigates failures, who replaces stock).
• Documentation availability (certificates, traceability data, and change notifications).

Hospitals benefit from asking: Who actually manufactures the critical components, and what is the escalation route if failures occur?

Access and product variety are usually stronger in large urban centers than in remote regions.

Turkey

Turkey has a well-developed healthcare sector with significant surgical capacity in both public and private hospitals. Demand for Ophthalmic viscoelastic injector is supported by high ophthalmology case volumes and an active medical device distribution ecosystem. Urban regions typically have strong access to branded consumables and service support, while smaller facilities may rely more on distributor-led standardization.

Germany

Germany’s market is characterized by strong regulatory compliance expectations, structured procurement, and high emphasis on traceability and validated sterile workflows. Ophthalmic viscoelastic injector purchasing is often integrated into standardized surgical packs and closely managed inventory systems. Access is generally broad, though procurement decisions may be influenced by regional contracting and hospital network policies.

Thailand

Thailand’s demand is driven by a mix of public hospital services, private sector growth, and established ophthalmology centers in major cities. Import dependence for some consumables makes distributor reliability and regulatory navigation important for continuity. Urban access to product options and training is typically strong, while rural areas may face narrower product selection and longer supply lead times.

Key Takeaways and Practical Checklist for Ophthalmic viscoelastic injector

• Treat Ophthalmic viscoelastic injector as a sterile, eye-entering clinical device.
• Confirm correct product identity before opening any sterile pack.
• Check packaging integrity; discard if seals are damaged or wet.
• Verify expiry date and lot number for traceability and recalls.
• Separate look-alike OVD syringes on the sterile field to prevent mix-ups.
• Use only compatible cannulas and connectors specified by the IFU.
• Ensure the cannula connection is secure before applying injection force.
• Prime per protocol to reduce air and confirm patency.
• Never force the plunger against unexpected resistance without reassessing.
• Expect viscosity-related resistance; injection should be slow and controlled.
• Treat sudden loss of resistance as a potential surge risk.
• Protect the cannula tip from contact until the moment of use.
• Use safe hand-off technique to avoid accidental plunger depression.
• Keep a spare injector/cannula immediately available during critical steps.
• Document product used in the operative record when required.
• Use UDI scanning where available to strengthen device traceability.
• Discard single-use injectors and cannulas after one case.
• Do not reprocess single-use components unless IFU explicitly permits it.
• Manage cannulas as sharps; dispose immediately in approved containers.
• If contamination is suspected, replace the device without debate.
• If leakage is seen at the connector, stop and replace the system.
• If repeated issues occur, quarantine remaining stock and notify leadership.
• Build a non-punitive culture for reporting device failures and near misses.
• Standardize SKUs to reduce training burden and selection errors.
• Align preference cards with formulary-approved OVD and injector options.
• Store products within labeled temperature and handling limits.
• Train scrub staff on assembly, priming, and sterile presentation.
• Include Ophthalmic viscoelastic injector steps in OR time-out readiness checks.
• Clarify escalation pathways to procurement, quality, and biomedical engineering.
• Keep manufacturer IFU accessible in the OR and sterile processing areas.
• Audit waste and opened-but-unused packs to identify process improvements.
• Validate distributor reliability for high-volume cataract service continuity.
• Plan for supply disruptions by qualifying acceptable alternatives in advance.
• Review labeling language needs for multilingual teams and compliance.
• Integrate lot/expiry capture into digital systems where feasible.
• Coordinate with infection prevention on any reusable component onboarding.
• Reassess training after staff turnover or when product models change.
