Anterior chamber maintainer: Overview, Uses and Top Manufacturer Company

Introduction

Anterior chamber maintainer is a small but high-impact ophthalmic medical device used during intraocular (inside-the-eye) surgery to keep the anterior chamber (AC) formed and stable. In plain language, it continuously delivers sterile irrigating fluid into the front chamber of the eye so the surgeon can work in a controlled space without the chamber collapsing.

In busy eye theaters and ambulatory surgery centers, this clinical device can support smoother surgical flow, especially during manual or complex anterior segment procedures where stable intraocular pressure (IOP) and consistent chamber depth matter. For hospitals, it also touches multiple operational domains: sterile supply, consumables standardization, staff competency, equipment maintenance readiness, infection prevention, and incident reporting.

This article explains what Anterior chamber maintainer is, where it is commonly used, when it may not be suitable, and what safe operation typically looks like across different models (gravity-fed and machine-assisted). It also covers patient safety practices, common troubleshooting, cleaning and reprocessing considerations (where applicable), and a practical global market overview aimed at both learners and hospital decision-makers.

This is an educational and operational overview only. Specific clinical decisions and surgical technique must follow local protocols, supervision requirements, and the manufacturer’s instructions for use (IFU).

What is Anterior chamber maintainer and why do we use it?

Clear definition and purpose

Anterior chamber maintainer is a sterile infusion cannula system designed to maintain a formed anterior chamber during anterior segment surgery. Its core purpose is to provide continuous, controlled inflow of an irrigating solution (commonly balanced salt solution, often abbreviated as BSS) to help:

• Maintain chamber depth and stability
• Reduce sudden fluctuations in intraocular pressure (IOP) during instrument exchanges
• Support clearer visualization and safer tissue handling in a small surgical space

It is “simple” hospital equipment in appearance, but it sits at the center of intraoperative fluidics: inflow must be appropriate for the outflow and leakage created by surgical incisions and instruments.

Common clinical settings

Anterior chamber maintainer is most often encountered in operating rooms performing:

• Cataract surgery, especially manual techniques or steps where a separate irrigation source is useful
• Anterior vitrectomy (for example, when maintaining the chamber during certain maneuvers)
• Intraocular lens (IOL) procedures where stable chamber depth supports positioning and safety
• Selected corneal and glaucoma procedures where chamber stability is important (use varies by surgeon and facility)

In some settings, surgeons rely on phacoemulsification (phaco) systems and their integrated irrigation to maintain the chamber. In others—particularly high-volume manual cataract programs—Anterior chamber maintainer may be a routine part of the surgical set.

Key benefits in patient care and workflow

From a clinical and operational perspective, typical benefits include:

• More stable surgical field: Less chamber shallowing during instrument entry/exit
• Reduced interruptions: Fewer pauses to reform the chamber
• Supports bimanual workflows: Allows the surgeon to dedicate other hand(s) to instruments rather than chamber maintenance (technique-dependent)
• Teaching value: Trainees can better appreciate intraoperative fluidics when chamber stability is visually obvious
• Predictable consumable planning: Often a standardized item that can be bundled into cataract packs (varies by facility)

These benefits depend heavily on correct setup, priming, and pressure control—areas where small errors can create meaningful risk.

Mechanism of action (plain language)

Most Anterior chamber maintainer systems work by one of two broad methods:

• Gravity-driven infusion: A bottle/bag of irrigating solution is elevated above the patient’s eye. The height of the fluid column provides pressure, producing flow through the tubing and cannula.
• Machine-assisted infusion: The infusion line is driven or regulated by a surgical console or pump capable of maintaining a target pressure/flow (implementation varies by manufacturer).

In both cases, the cannula tip sits in the anterior chamber through a small incision. When infusion is started, fluid flows into the chamber and exits through the main incision, side ports, or around instruments, maintaining a “formed” chamber.

How medical students typically encounter it in training

Medical students and residents typically meet Anterior chamber maintainer in three ways:

• Observation in the OR: Recognizing the infusion line and side-port cannula and understanding why it is used
• Wet-lab or simulation: Learning the basics of ocular fluidics, chamber stability, and the consequences of air bubbles or incorrect pressure
• Instrument familiarization: Understanding how this medical equipment differs from viscoelastic (ophthalmic viscosurgical device, OVD) and from integrated irrigation on phaco systems

For trainees, the high-yield learning point is that chamber stability is a dynamic balance of inflow, outflow, incision architecture, and instrument movement—not a fixed “setting.”

When should I use Anterior chamber maintainer (and when should I not)?

Appropriate use cases (general)

Use of Anterior chamber maintainer depends on surgeon preference, procedure type, and the facility’s standard technique. Common scenarios where teams may consider it include:

• Procedures where consistent chamber formation is needed while instruments are frequently exchanged
• Manual cataract workflows where separate irrigation helps maintain chamber stability
• Cases where the team anticipates higher leakage from incisions or a need for longer intraocular time
• Training environments where a stable chamber can help reduce nonessential variability while teaching fundamentals
• Situations where the surgical plan benefits from having irrigation available independently of aspiration or phaco steps (workflow-dependent)

In many facilities, the decision is protocol-driven (for example, included in a cataract tray) rather than case-by-case, but exceptions still occur.

When it may not be suitable

Anterior chamber maintainer may be less suitable or used differently when:

• The surgical platform already provides adequate irrigation and the additional port adds unnecessary complexity
• The incision strategy does not support an additional cannula without increased leakage risk
• The team cannot ensure correct sterile setup, priming, and secure connections
• The patient’s clinical context requires specialized decisions beyond a general overview (the operating surgeon determines appropriateness)

It is also important to consider the system-level suitability: if a facility struggles with sterile processing capacity, supply chain reliability, or staff competency, adding steps and consumables can increase risk unless those gaps are addressed.

Safety cautions and contraindications (general, non-prescriptive)

Because Anterior chamber maintainer directly affects intraocular pressure and fluid dynamics, general cautions include:

• Overpressure risk: Excess infusion pressure can raise IOP and stress intraocular tissues.
• Underpressure risk: Too little infusion can allow chamber collapse and reduce control.
• Air embolus/bubble risk: Air in the line can enter the eye, compromising visibility and safety.
• Wrong fluid risk: Incorrect solution selection or contamination can create serious harm.
• Mechanical trauma risk: Poorly positioned or unstable cannula placement can injure tissues.
• Connection integrity risk: Leaks or disconnections can rapidly change chamber stability.

Contraindications are procedure- and patient-specific and are typically defined by the manufacturer IFU and the surgeon’s clinical assessment. In practice, the safest framing for trainees and hospital teams is: use Anterior chamber maintainer only within established protocols, under appropriate supervision, and with the correct sterile consumables and setup.

What do I need before starting?

Required environment and core accessories

Most setups require:

• Sterile ophthalmic operating room environment (or equivalent clean procedure space where indicated)
• Operating microscope and standard anterior segment instrument set
• Sterile irrigating solution (commonly BSS; exact type depends on local protocol)
• Sterile infusion tubing compatible with the fluid source and cannula connector (often Luer-based; compatibility varies)
• Flow control component (roller clamp and/or stopcock, depending on the set)
• A stable IV pole or bottle hanger capable of consistent height positioning (for gravity systems)
• If machine-assisted, a compatible surgical console/infusion regulator (varies by manufacturer)

From an operations standpoint, this is both a consumable pathway (cannula, tubing, solution) and an equipment pathway (stands, consoles, clamps).

Training and competency expectations

Because this clinical device can directly influence intraocular pressure, facilities typically define competency for:

• Surgeons/trainees: Indication selection, safe intraocular handling, and response to fluidics problems
• Scrub staff: Sterile assembly, priming, connection integrity checks, and anticipating surgeon needs
• Circulating staff: Fluid inventory management, documentation, and supporting troubleshooting without breaking sterility
• Biomedical engineering (clinical engineering): Preventive maintenance and safety checks for pumps/stands/consoles, where relevant
• Sterile processing (SPD/CSSD): Reprocessing steps for any reusable components (varies by manufacturer)

Competency should be documented and refreshed when models, tubing sets, or connectors change.

Pre-use checks and documentation (practical)

Common pre-use checks include:

• Confirm correct item: “Anterior chamber maintainer” and compatible tubing set for the planned technique
• Check packaging integrity and sterility indicators
• Check expiration date and lot/serial identifiers (as available)
• Inspect the cannula for bends, burrs, cracks, or blocked lumen (visual check only; do not compromise sterility)
• Confirm connector compatibility (avoid forcing mismatched fittings)
• Confirm irrigating solution type, clarity, and labeling
• Prime the line to remove air (a critical safety step)
• Confirm the flow control device (clamp/stopcock) operates smoothly
• Document according to policy: lot number, product code, and any deviations or issues

Documentation matters operationally because consumable traceability supports investigation of adverse events and supply quality issues.

Operational prerequisites (commissioning, maintenance readiness, consumables, policies)

Hospitals typically need:

• A clear policy on single-use versus reusable components (Varies by manufacturer; some cannulas are single-use, others may be reusable if validated)
• Sterile processing instructions aligned with the IFU, including validated sterilization cycles
• Backup stock for high-volume cataract lists (avoid last-minute substitutions)
• Commissioning checks for any infusion regulators or pumps used with the system
• A standard work instruction (SWI) or checklist that matches the chosen workflow
• A procurement plan that considers total cost: consumables, reprocessing labor, sterilization packaging, and wastage from opened-but-unused items

Roles and responsibilities (who does what)

• Clinician (surgeon): Decides whether to use Anterior chamber maintainer and directs intraoperative adjustments
• Scrub nurse/technologist: Assembles the sterile circuit, primes, hands off, and maintains sterile field discipline
• Circulating nurse: Manages fluid supply, documentation, and supports troubleshooting logistics
• Biomedical engineering: Ensures any related hospital equipment (pumps/stands) is safe, calibrated as applicable, and serviceable
• Procurement/supply chain: Sources standardized SKUs, manages vendor qualification, and maintains continuity of supply
• Infection prevention and SPD/CSSD: Validates and audits reprocessing pathways and compliance

Clear role boundaries reduce errors during fast-paced, high-volume surgical lists.

How do I use it correctly (basic operation)?

Universal workflow principles (model-agnostic)

Exact steps vary by manufacturer and surgical technique, but several steps are commonly universal:

1. Confirm intended use and compatibility
   Ensure the cannula, tubing, and fluid source are intended for intraocular irrigation and are compatible with each other.

2. Maintain sterile setup
   Open and assemble the sterile components using standard aseptic technique.

3. Assemble the infusion circuit
   Connect the irrigating solution container to tubing, then to the cannula hub (connector style varies). Keep the distal end sterile.

4. Prime the tubing completely
   Remove all air from the line before the cannula is introduced. Small air bubbles can matter in eye surgery.

5. Control flow before insertion
   Use a clamp/stopcock to keep flow off until the surgeon requests infusion.

6. Position the pressure source
   – Gravity systems: position the bottle/bag at the planned height and ensure the stand is stable.
   – Machine-assisted systems: confirm the device is in the correct mode and any self-checks are complete.

7. Surgeon introduces the cannula
   The surgeon inserts the cannula through an appropriate incision per the surgical plan and confirms stable positioning.

8. Start infusion and confirm chamber stability
   Begin infusion gradually and confirm the chamber is formed and stable. Adjust pressure/height as needed.

9. Continue intraoperative monitoring
   Monitor for leakage, line kinks, disconnections, unexpected chamber shallowing, or excessive deepening.

10. Stop infusion prior to removal
    Clamp/stop infusion before cannula removal to reduce sudden pressure changes and fluid egress.

11. Post-use handling
    Dispose of single-use components per policy or send reusable components for reprocessing per IFU. Document lot numbers and any issues.

Typical “settings” and what they mean (general)

Anterior chamber maintainer commonly has indirect “settings” rather than a complex user interface:

• Bottle/bag height (gravity): Higher height generally increases infusion pressure and flow; lower height decreases it.
• Clamp/roller control: Adjusts or stops flow without changing height.
• Stopcock position: Directs flow on/off or allows flushing pathways (depending on configuration).
• Cannula gauge and lumen size: Affects resistance and achievable flow; selection is technique-dependent.
• Console pressure/flow targets (machine-assisted): Some systems display infusion pressure or target values, but the displayed number may not equal true IOP.

Because these variables interact, teams should avoid making rapid, large changes unless directed by the surgeon and supported by protocol.

Steps that deserve extra attention in real-world ORs

• Priming: Many intraoperative problems trace back to incomplete priming or air bubbles.
• Connection security: Luer-style connections can loosen if tubing is under tension.
• Tubing routing: Prevent kinks and avoid pulling across the sterile field.
• Stand stability: A bumped pole can change height and therefore infusion pressure.

Even when the cannula itself is uncomplicated, the full system behaves like a fluidics circuit and should be treated accordingly.

How do I keep the patient safe?

Understand the main risk categories

Anterior chamber maintainer changes intraocular conditions in real time. Safety risks are typically grouped into:

• Pressure-related risks
  Over-infusion can raise IOP; under-infusion can lead to chamber collapse. Either can reduce surgical control.

• Air and particulate risks
  Air bubbles, particulate contamination, or precipitates can enter the anterior chamber if the line is not properly managed.

• Mechanical risks
  Poor cannula stability, inappropriate positioning, or unintended movement can injure delicate tissues.

• Infection and sterility risks
  Because the device enters a sterile intraocular environment, breaches in sterility are high-consequence.

• Human factors risks
  Confusion over clamps/stopcocks, pressure source height, or “who is adjusting what” can cause abrupt changes.

Safety practices (practical, team-based)

Common safety controls used by high-performing teams include:

• Pre-procedure briefing: Confirm whether Anterior chamber maintainer will be used, and who will manage the infusion source (scrub vs circulating, per local practice).
• Right fluid, right label: Verify the irrigating solution type and expiration, and keep it visually distinct from non-ocular fluids.
• Prime-and-verify: Prime until bubble-free, then perform a final visual check of the line immediately before intraocular entry.
• Secure connections: Avoid tension on tubing; ensure connectors are fully seated without over-tightening.
• Controlled initiation: Start infusion gradually and confirm chamber response before proceeding.
• Avoid unnecessary adjustments: If multiple staff can change bottle height or console settings, define a single point of control to prevent conflicting actions.
• Monitor the system, not just the eye: Observe bottle level, clamp position, kinks, and drape routing during critical steps.
• Use standardized communication: Simple phrases like “infusion on,” “infusion off,” and “hold pressure” reduce ambiguity.

Monitoring and situational awareness

Monitoring is typically continuous and visual/tactile:

• Chamber depth and stability (surgeon view)
• Leakage from incisions
• Cannula position stability
• Presence of bubbles migrating in tubing
• Infusion source level (avoid running dry)
• Console alarms (if using machine-assisted infusion)

Because the Anterior chamber maintainer does not “diagnose” anything, safety comes from process control rather than interpreting a single numeric value.

Alarm handling and human factors

If connected to a console or pump, alarms may relate to:

• Occlusion or high pressure
• Air detection (in some systems)
• Door open or cassette issues (system-dependent)
• Low fluid level (system-dependent)

General best practices:

• Do not silence or override alarms without understanding the cause.
• Treat alarms as prompts for a structured check: line patency, clamp position, connections, fluid source, and cannula position.
• Report recurrent nuisance alarms to biomedical engineering; they can indicate calibration, maintenance, or consumable compatibility issues.

Follow guidance, build a reporting culture

• Follow the manufacturer IFU for compatible fluids, priming steps, connection torque, and single-use restrictions.
• Use facility protocols for time-outs, traceability, and sterile field management.
• Encourage reporting of near-misses (e.g., air found in line before insertion). Near-miss learning is often the fastest way to improve reliability in high-volume cataract programs.
• Preserve packaging and lot details if a device defect is suspected.

How do I interpret the output?

What “output” looks like for this device

Anterior chamber maintainer typically provides functional output rather than diagnostic output. Common “outputs” include:

• Visual chamber stability: A formed anterior chamber that remains stable during instrument exchanges
• Observed flow behavior: Whether inflow appears smooth and continuous versus intermittent or absent
• Console values (if applicable): Some setups show infusion pressure targets, estimated pressure, or flow-related metrics (Varies by manufacturer)

Importantly, an Anterior chamber maintainer does not inherently measure true intraocular pressure unless paired with additional technology. Many systems infer or approximate pressure based on the infusion system, which can be affected by resistance, leakage, and positioning.

How clinicians typically interpret it (general)

Clinicians interpret performance by correlating:

• The surgical view (stable anatomy and working space)
• The responsiveness of the chamber when infusion is adjusted
• The presence or absence of sudden fluctuations when instruments are inserted/removed
• Any changes that coincide with line manipulation (kink, clamp movement, bottle height change)

This is an applied fluidics assessment, not a single-number interpretation.

Common pitfalls and limitations

• Bottle height is not the same as eye pressure: Leakage and resistance change the relationship.
• Leaks mimic “low pressure”: A stable bottle height may still produce a shallow chamber if leakage increases.
• Occlusion mimics “high pressure”: A kinked line can create upstream pressure with poor inflow.
• Air bubbles can be missed: Small bubbles may cling to tubing walls and move later.
• False reassurance from “normal-looking” tubing: Patency problems can occur at the cannula tip even when tubing looks fine.

The safest interpretation approach is to treat chamber behavior as a system response and troubleshoot both the eye-side and equipment-side contributors.

What if something goes wrong?

A practical troubleshooting checklist (sterile-field aware)

When performance is not as expected, a structured checklist helps:

1. Pause and stabilize
   If safe and directed by the surgeon, stop infusion changes and stabilize the field.

2. Check flow control first
   Confirm clamp/roller and stopcock position (a common source of error).

3. Check the fluid source
   Ensure the bottle/bag is not empty, the spike is correctly placed, and the venting method (if used) matches the container type.

4. Check tubing routing
   Look for kinks under drapes, pinched segments, or tension pulling on connectors.

5. Check connectors for leaks or loosening
   Confirm connections are seated and not cross-threaded (where applicable).

6. Assess for air
   If bubbles are present, stop, re-prime as appropriate, and follow local protocol.

7. Check cannula patency and position
   Cannula tip obstruction, malposition, or instability can reduce effective inflow.

8. Reassess pressure source settings
   Gravity: verify bottle height has not changed.
   Machine-assisted: confirm correct mode and settings; acknowledge and address alarms.

9. Swap consumables if needed
   If sterility and protocol allow, replacing the tubing/cannula is often faster than prolonged troubleshooting.

When to stop use

Stop using the Anterior chamber maintainer (and follow the team’s escalation pathway) if:

• Sterility is in doubt (contamination, dropped tip, packaging breach discovered late)
• Air cannot be reliably cleared
• Connectors are damaged, leaking, or incompatible
• Chamber stability cannot be achieved despite standard checks
• A device defect is suspected that could pose ongoing risk

Clinical decisions on intraoperative alternatives belong to the surgical team and local protocol.

When to escalate to biomedical engineering or the manufacturer

Escalate to biomedical/clinical engineering when:

• A console/pump shows repeated alarms or inconsistent performance
• A pole/stand cannot maintain stable height or has mechanical instability
• Electrical safety or maintenance status is uncertain
• There is repeat failure across multiple cases suggesting a system issue

Escalate to the manufacturer/vendor when:

• A consumable defect is suspected (blocked lumen, connector failure, packaging integrity issue)
• Multiple units from the same lot show anomalies
• IFU ambiguity affects safe use (request clarification through formal channels)

Documentation and safety reporting (general expectations)

• Record lot numbers, item identifiers, and the nature of the issue.
• Save the device and packaging when feasible for investigation (follow policy).
• File an internal incident report, including near-misses.
• Follow local regulatory reporting obligations as defined by your facility (requirements vary by country).

Infection control and cleaning of Anterior chamber maintainer

Why infection control is especially strict here

Anterior chamber maintainer interfaces with a sterile intraocular environment. As a result, infection prevention standards are typically more stringent than for non-invasive hospital equipment. Even small process deviations can have high consequences.

Single-use vs reusable: know what you have

Reprocessing status varies by manufacturer:

• Many anterior segment cannulas and tubing sets are intended as single-use sterile disposables.
• Some cannulas may be reusable when supplied with validated reprocessing instructions and compatible sterilization pathways.

Facilities should avoid informal “workarounds” such as reprocessing items labeled single-use, unless there is a legally compliant, validated reprocessing program in place (which varies by jurisdiction).

Disinfection vs sterilization (general concepts)

• Cleaning: Physical removal of soil and bioburden; always required before further processing.
• Disinfection: Reduces microorganisms but may not eliminate spores; often insufficient for intraocular instruments unless explicitly validated for that use.
• Sterilization: A validated process to eliminate all forms of microbial life; typically required for instruments that enter sterile body sites.

For devices entering the anterior chamber, sterilization is commonly expected, but the exact method must follow the IFU (steam, low-temperature sterilization, etc., depending on materials).

High-touch points beyond the cannula

In addition to the sterile cannula itself, infection control programs often focus on:

• IV poles and bottle hangers (frequently handled, sometimes overlooked)
• Pump/console buttons and touch surfaces
• Clamps and reusable flow-control accessories
• Storage bins, trays, and transport containers used for sterile components

These are “small surfaces” that can drive cross-contamination when cleaning routines are inconsistent.

Example cleaning workflow (non-brand-specific)

For a reusable component (only if allowed by IFU):

1. Point-of-use care
   Keep lumens from drying when possible (per policy) and prevent gross contamination from hardening.

2. Safe transport
   Send to SPD/CSSD in a closed, labeled container to prevent environmental contamination.

3. Cleaning
   Use approved detergents, lumen flushing, and appropriate brushes for cannulated instruments (exact tools depend on lumen size).

4. Rinse and dry
   Ensure detergent residue is removed and lumens are dried as required by the sterilization method.

5. Inspection and function check
   Verify patency and inspect for damage, corrosion, or deformation.

6. Packaging and sterilization
   Package with appropriate indicators and run validated sterilization cycles per IFU.

7. Storage and traceability
   Store in a protected, clean area and maintain traceability to sets and cases as required.

For a single-use item:

• Discard immediately after use in accordance with facility policy for sharps/clinical waste.
• Do not attempt to clean, sterilize, or repackage.

Align with IFU and facility policy

• The manufacturer IFU is the primary source for validated reprocessing steps.
• The facility infection prevention policy defines what is permitted in practice, including audits, monitoring, and documentation.
• If there is a mismatch between IFU and local capability (e.g., sterilizer type not available), treat that as an operational risk that requires resolution before routine use.

Medical Device Companies & OEMs

Manufacturer vs. OEM: what the terms mean in procurement

• Manufacturer (brand owner/legal manufacturer): The entity responsible for the device design, labeling, quality management system, regulatory filings, and post-market surveillance obligations (definitions vary by jurisdiction).
• OEM (Original Equipment Manufacturer): A company that produces components or complete devices that may be sold under another company’s brand.

In ophthalmic consumables, OEM relationships are common. An Anterior chamber maintainer may be branded by one company but physically produced by another under contract.

How OEM relationships affect quality, support, and service

OEM structures are not inherently good or bad, but they affect what hospitals experience:

• Quality consistency: Depends on supplier qualification, incoming inspection, and process controls across the supply chain.
• Availability and substitutions: Multiple branded products may share similar designs; during shortages, substitutions may occur, raising connector compatibility and training issues.
• Support pathways: Complaints and technical questions may route through the brand owner, not directly to the OEM, which can influence response time.
• Documentation: IFU clarity, traceability, and change control (e.g., connector redesign) matter operationally.

For procurement teams, the practical question is whether the supplier can provide reliable documentation, consistent product specifications, and responsive post-market support.

Vendors, Suppliers, and Distributors

Role differences: vendor vs supplier vs distributor

These terms are sometimes used interchangeably, but procurement teams often distinguish them:

• Vendor: The entity you contract with and pay; may be a distributor, manufacturer, or group purchasing organization partner.
• Supplier: The organization that provides goods into your supply chain; could be the manufacturer or an intermediary.
• Distributor: A company focused on warehousing, logistics, and fulfillment, often carrying multiple brands and supporting delivery, returns, and sometimes basic technical coordination.

For Anterior chamber maintainer, the distributor’s role is often critical because timely delivery, correct SKUs, and lot traceability matter as much as unit price.

Key Takeaways and Practical Checklist for Anterior chamber maintainer

• Anterior chamber maintainer is primarily a fluidics-stability tool, not a diagnostic device.
• Define “anterior chamber (AC)” and “intraocular pressure (IOP)” early when teaching trainees.
• Treat the infusion line as a high-risk pathway because it enters a sterile intraocular space.
• Select the cannula and tubing set that matches the planned workflow and connectors.
• Verify packaging integrity, sterility indicator status, and expiration before opening.
• Confirm the irrigating solution type and labeling per local ophthalmic protocol.
• Prime the tubing until bubble-free; visually re-check immediately before insertion.
• Keep the cannula tip sterile at all times; avoid contact with non-sterile surfaces.
• Use a clamp or stopcock to control flow predictably before intraocular entry.
• Ensure the IV pole or bottle hanger is stable and unlikely to be bumped mid-case.
• Remember that gravity bottle height influences pressure; avoid unplanned height changes.
• If using a console, confirm the correct infusion mode and complete self-checks.
• Assign one person to adjust infusion settings to reduce conflicting actions.
• Use standardized phrases like “infusion on” and “infusion off” for closed-loop communication.
• Watch for tubing kinks under drapes; reroute early rather than repeatedly correcting.
• Monitor connections for loosening when the line is under tension.
• Do not assume bottle height equals true IOP; leakage and resistance change the relationship.
• Treat sudden chamber changes as system problems: eye-side plus equipment-side causes.
• If flow is poor, check clamp/stopcock position before changing any settings.
• If alarms occur, investigate the cause; do not routinely silence without correction.
• Keep track of fluid level to prevent the infusion source from running dry.
• Consider having a spare sterile set available on high-volume cataract lists.
• Stop and escalate if sterility is compromised or air cannot be reliably cleared.
• Document lot numbers and product identifiers to support traceability and investigations.
• Preserve the device and packaging if a defect is suspected, per facility policy.
• Align use with a standard work instruction (SWI) that matches the local technique.
• Clarify whether components are single-use or reusable; reprocessing status varies by manufacturer.
• Never reprocess items labeled single-use unless a compliant validated program exists.
• If reusable, ensure SPD/CSSD has validated cleaning tools for cannulated lumens.
• Separate cleaning, disinfection, and sterilization concepts in staff training.
• Include IV poles, clamps, and console touchpoints in environmental cleaning routines.
• Build competency assessment into onboarding for scrub and circulating staff.
• Engage biomedical engineering for maintenance readiness of pumps, consoles, and stands.
• Procurement should standardize SKUs to reduce connector variability and training burden.
• Evaluate total cost of ownership: consumables, reprocessing time, packaging, and waste.
• Require clear IFU access in the local language(s) used by staff when feasible.
• Use incident reporting for near-misses (e.g., bubble found pre-insertion) to improve systems.
• Review recurring issues in multidisciplinary forums: surgery, nursing, SPD, biomed, procurement.
• Plan supply buffers where import dependence or logistics variability can disrupt cataract lists.
• In global programs, match device choice to sterilization capacity and distribution reliability.
• Standardization and disciplined priming practices often deliver the biggest safety gains.
