10.3 Surgical Instrument Handling, Tray Setup & Sterilization

Instrument Handling, Tray Setup, and Sterilization

Ophthalmic instruments are delicate and may enter sterile tissue. A safe reprocessing chain preserves both microbial safety and device function. The technician follows the instrument instructions for use, reprocessing policy, sterilizer instructions, detergent label, and applicable standards.

Point-of-use care and transport

After use, prevent soil from drying by applying the approved point-of-use method. Do not soak instruments in saline unless the manufacturer permits it; chloride can corrode metal. Remove disposables and sharps into their assigned containers without hand manipulation. Transport contaminated devices in a closed, labeled, leak-resistant container to the decontamination area.

Separate contaminated and clean flow. Wear task-appropriate personal protective equipment. Never carry an exposed sharp or open tray through a clean corridor.

Cleaning

Cleaning removes blood, protein, medication, viscoelastic, and debris before a microbicidal process. Disassemble and open instruments as directed. Use the specified water, detergent concentration, temperature, contact time, brush, flushing volume, and ultrasonic cycle. Fine lumens and handpieces require validated adapters and flow.

Ultrasonic cleaning may be appropriate for some hinged instruments but not for every powered, coated, glued, or delicate device. Keep dissimilar materials separated when the instructions require it. Change solution and degas the unit according to policy. Do not substitute household bleach, tap-water additives, or an unapproved enzyme.

Rinse thoroughly using the specified water quality. Residual detergent, enzyme, endotoxin, metal ions, or viscoelastic can contribute to toxic anterior segment syndrome or instrument damage.

Inspection and assembly

Under magnification, inspect tips, joints, teeth, insulation, lumens, optics, alignment, corrosion, cracks, residue, and function. Remove a damaged or soiled item from service. Lubricate only with a compatible product. Assemble the tray so steam or the selected sterilant can contact all surfaces and so fine tips are protected without being compressed.

Count and identify instruments against the tray list. Verify that no single-use device has entered an unauthorized reuse process.

Packaging and sterilization

Choose wrap, pouch, rigid container, filter, and indicator compatible with the instrument and cycle. Label the package with load and traceability information without compromising the barrier.

Steam cycles differ by sterilizer type, load, packaging, instrument design, altitude, and manufacturer validation. A common teaching number cannot replace the cycle selected in the current instructions. The same principle applies to ethylene oxide, hydrogen-peroxide systems, and other low-temperature methods. Aeration time for ethylene oxide depends on device material, cycle, temperature, and validated instructions; it is not universally 12 or 24 hours.

Monitor the process with:

• physical records: time, temperature, pressure, alarms, and cycle printout;
• chemical indicators: exposure inside and outside packages as required;
• biological indicators: used at the frequency and for the sterilization method specified by policy and standards;
• load documentation: sterilizer, cycle, contents, operator, results, and release decision.

Do not release a load after an aborted cycle, failed indicator, missing record, wet package, torn wrap, or unresolved alarm. Quarantine and follow recall procedures when a monitoring failure affects prior loads.

Storage and procedure setup

Store sterile packages in a protected, dry area and handle them as little as possible. Event-related contamination includes moisture, crushing, tearing, puncture, opened seals, or questionable handling. Inspect every package before presentation.

At setup, reconcile the procedure and surgeon preference card, verify sterility and expiration where applicable, and arrange items to protect tips and maintain count visibility. A package that looks different or lacks traceability is not used until verified.

TASS and incident prevention

Toxic anterior segment syndrome is sterile postoperative inflammation associated with contaminants introduced during surgery. Prevention focuses on complete cleaning and rinsing, validated water, correct detergent and enzyme use, medication preparation, instrument separation, and documentation. Report a cluster or unusual residue immediately so infection and toxic causes can be investigated.

The governing rule is simple: current validated instructions control every step, and an uncertain device remains out of service.

Point-of-use care and traceability

At point of use, keep soil from drying by the method permitted for that device; do not immerse powered components or use saline when the instructions prohibit it. Count sharps and delicate tips, segregate damaged items, and transport contaminated instruments in a closed, labeled container. Cleaning must precede high-level disinfection or sterilization because retained organic material can shield organisms and interfere with the process.

Inspection under adequate light and magnification should check hinges, lumens, insulation, alignment, corrosion, residue, and function. Assemble and package only as the device and sterilizer instructions allow. Traceability links the load and cycle to the patient or procedure when required. A wet, torn, opened, expired under local event-related policy, or otherwise compromised package is not presented as sterile. When a biological, chemical, or physical monitor fails, quarantine the load and follow the facility's investigation and recall procedure rather than rerunning items without documentation.
