Ophthalmic Equipment Servicing Checklist for Clinics

Reliable diagnostic equipment supports consistent testing, efficient appointments and confident clinical decisions. Servicing can become reactive when practices lack a clear maintenance schedule, complete equipment records or defined staff responsibilities.

A structured ophthalmic equipment servicing checklist helps practice managers and biomedical teams identify small faults before they interrupt consulting sessions. It gives multi-site operators a consistent method for tracking calibration, cleaning, repairs and scheduled technical work across each location.

This checklist covers routine user checks, planned technical servicing, high-risk warning signs and service-log requirements. The exact schedule for each instrument must follow its current instructions for use, warranty terms and manufacturer service requirements.

Key Highlights

Create one service schedule: Bring daily checks, monthly controls and technical servicing dates into one system.
Track every clinical asset: Record the model, serial number, room, service history and next scheduled visit.
Treat calibration failures as clinical risks: Remove affected measuring equipment from use until it has been assessed.
Standardise checks across every site: Use the same checklist, fault labels and escalation process in each clinic.
Plan maintenance before appointments are affected: Book preventive servicing rather than waiting for a full breakdown.

Daily, Monthly and Annual Checks

A preventative maintenance checklist should separate tasks that clinic staff can complete from work that requires a trained service technician.

Australian medical-device guidance treats the manufacturer’s instructions for use as the main source for safe operation and device requirements. Current guidance for reusable medical devices states that reprocessing must align with applicable standards and manufacturer instructions.

The intervals below provide a clinic-planning framework. The equipment manufacturer’s instructions and service advice take precedence.

Frequency	Clinic checks	Person responsible	Record required
Before use or daily	Inspect for visible damage, confirm normal movement, test start-up, review image or measurement quality and clean approved surfaces	Trained equipment user	Fault entry when an issue is found
Monthly	Review calibration checks where applicable, inspect leads and accessories, test backup processes and review unresolved faultsand screening	Equipment lead or practice manager	Monthly checklist
Quarterly or six-monthly	Review asset condition, software status, recurring faults, environmental conditions and upcoming service dates	Practice manager or biomedical team	Asset review
Annual or manufacturer-defined interval	Complete internal inspection, calibration, optical alignment, mechanical assessment and safety testing where applicable	Qualified technician	Service report and certificate
After relocation or impact	Check alignment, operation, connections and measurement performance before clinical use	Qualified staff member or technician	Relocation or incident record

Daily Checks Before the First Appointment

Daily checks should be brief enough to complete without delaying the clinic. They should focus on visible condition, basic operation and results that appear abnormal.

Clinic staff can check:

The instrument is stable and correctly positioned.
Electrical leads, plugs and data cables have no visible damage.
Chin rests, forehead rests, handles and controls are secure.
Joysticks, tables, arms and locking mechanisms move normally.
Lenses, mirrors, screens and camera windows are free from visible marks.
Illumination starts correctly without flickering or unusual delay.
The instrument completes its normal start-up sequence.
Test images or readings do not show new artefacts or unexplained variation.
Patient-contact components have been reprocessed under the approved procedure.
Dust covers and approved protective accessories are used when the device is idle.

Never apply an unapproved cleaner to coated optics, displays, measuring prisms or camera windows. The product instructions should identify suitable agents, concentrations, contact times and drying methods.

A systematic review of Goldmann tonometer disinfection found only 19 primary studies and could not identify one disinfectant as the best choice across every situation. This supports a device-specific process rather than a single clinic-wide chemical rule.

Monthly Equipment Controls

Monthly reviews can identify gradual changes that daily users may begin to accept as normal.

Your monthly optometry equipment maintenance checklist may include:

Complete any manufacturer-approved user calibration test.
Compare recurring readings or image concerns recorded during the month.
Check instrument tables for unwanted movement or loose locks.
Inspect frequently handled controls for wear.
Review air vents and external filters without opening the housing.
Confirm data exports, network connections and approved backup routines.
Check that calibration tools, test eyes and reference accessories are present.
Review outstanding service requests.
Confirm that fault labels remain attached to equipment removed from use.
Check the next scheduled technical service date.

Haag-Streit’s July 2025 calibration guide recommends a visual inspection before each use and a calibration check at least monthly for the listed Goldmann applanation tonometers. Any unit that fails the prescribed check should be assessed for servicing.

Annual or Manufacturer-Scheduled Servicing

Annual planning gives clinics a practical point for reviewing each instrument, but not every device follows a 12-month interval. Some systems require more frequent checks. Others use service intervals based on operating hours, model age or manufacturer instructions.

A technical service may cover:

Internal inspection for wear or contamination
Optical alignment and illumination assessment
Measurement calibration
Mechanical movement and lock testing
Inspection of electrical components
Replacement of approved wear parts
Software and firmware review
Error-log assessment
Cleaning that requires housing removal
Performance verification
Service documentation
Advice on remaining service life or parts availability

BOC Instruments supports clinics through professional servicing ophthalmic instruments, preventive maintenance, fault assessment and equipment repairs. A planned service program can help practices coordinate technical work before an overdue check or emerging fault affects clinical capacity.

Haag-Streit recommends annual servicing for its applanation tonometers, supported by calibration checks and a service certificate. Model requirements may differ, so clinics should confirm the schedule for each unit.

A planned service window can be booked during a quieter clinic period, staff training day or room closure. Multi-site groups can schedule one location at a time to retain testing capacity elsewhere.

Instruments That Need Scheduled Servicing

Every clinical device benefits from routine care, but instruments that measure, image or move near the patient warrant closer control.

Instrument	Main maintenance concerns	Routine clinic check	Reasons to request service
Applanation tonometer	Calibration, free arm movement, prism condition and mechanical wear	Approved calibration check and pre-use inspection	Failed calibration, sticking movement, impact damage or inconsistent readings
Slit lamp	Optical alignment, illumination, joystick movement and table stability	Check image clarity, light output and movement	Blurred view, drifting table, flickering illumination or stiff controls
OCT system	Scan quality, fixation, image artefacts, data storage and software	Run approved quality checks and review scan consistency	Repeated artefacts, failed scans, errors or unstable connectivity
Fundus camera	Focus, illumination, camera window, fixation and image transfer	Inspect sample images and external optical surfaces	New shadows, uneven lighting, focus problems or failed exports
Autorefractor or keratometer	Measurement repeatability, alignment and print or data output	Use an approved test eye where supplied	Repeatability changes, alignment errors or abnormal readings
Optical biometer	Measurement verification, fixation and software operation	Follow the manufacturer’s quality-control procedure	Unexpected variation, failed calibration or error messages
Visual field analyser	Fixation tracking, response controls, bowl condition and software	Test controls and review reliability warnings	Failed internal check, display fault or recurring fixation issue
Chairs, stands and tables	Movement, stability, locks, switches and cables	Inspect movement before patient use	Jerking, drift, noise, loose fittings or control failure

Tonometer Calibration

Tonometer calibration deserves a defined place in the clinic’s maintenance plan. Small mechanical errors can affect the reliability of intraocular pressure readings.

One hospital study assessed 43 Goldmann applanation tonometers. Ninety-three per cent were outside the manufacturer’s stated ±0.5 mmHg calibration range, and 28% had errors greater than ±2.5 mmHg. The researchers stated that further work was needed to connect calibration error directly with clinical error, yet the findings show the value of routine checks.

A separate study tested 132 tonometers and found that 21% were faulty at one or more testing levels. Among the faulty units, 53% displayed calibration variability of at least 2 mmHg. The authors advised against estimating the correct reading from a faulty instrument.

Clinics planning a replacement can compare available Tonometer models against their testing environment, mobility needs, patient flow and preferred measurement method. Calibration requirements, consumables and technical support should form part of the purchasing decision.

A failed calibration check should lead to a clear response:

Stop using the instrument for clinical measurements.
Attach a visible “Do Not Use” label.
Record the date, result and staff member.
Check that the test was completed under the manufacturer’s procedure.
Arrange assessment by a suitable service technician.
Record the repair, calibration result and return-to-use approval.

Slit Lamp Servicing

Regular slit lamp servicing can cover areas that daily cleaning cannot address. These may include optical alignment, internal dust, illumination systems, joystick movement, bearings and table stability.

The maintenance requirements of a slit lamp may vary by model, illumination source, imaging configuration and frequency of use. Clinics should retain the relevant instructions for use and keep any approved test procedures with the asset record.

Request an assessment when staff report:

A blurred view that remains after approved external cleaning
Double images or alignment concerns
Illumination that flickers or changes intensity
A joystick that sticks, drifts or moves unevenly
A table that lowers during an examination
Loose chin-rest components
New electrical noise, heat or odour
Imaging attachments that lose connection

Staff should not open the housing or attempt optical realignment unless they hold the required technical training and authorisation.

OCT Systems and Fundus Cameras

Imaging equipment may continue operating after image quality starts to decline. This can make early problems harder to identify.

Record and report recurring issues such as:

New lines, shadows or artefacts
Reduced scan quality under normal acquisition conditions
Repeated fixation or tracking failures
Slow start-up or processing
Unplanned software closure
Lost network connections
Failed image transfer
Storage warnings
Changes after equipment relocation
Faults that appear across several operators

Service planning for imaging equipment should cover the device, workstation, approved accessories and relevant connections. A problem that looks like an instrument fault may come from software, cabling, network access or storage capacity.

Signs Your Practice Is Carrying Downtime Risk

A clinic does not need to wait for equipment failure to identify a maintenance gap. Warning signs often appear in service records and staff workarounds.

Your practice may carry higher downtime risk when:

Service dates are stored in separate calendars or spreadsheets.
Equipment has no visible asset number.
Staff cannot find the current instructions for use.
Different sites use different fault-reporting processes.
A key diagnostic service depends on one instrument.
The same fault has been closed more than once without a lasting repair.
Team members need to restart equipment during normal sessions.
Image or measurement concerns are passed on verbally rather than recorded.
Service certificates cannot be matched to serial numbers.
Equipment has been moved without a post-relocation check.
Parts availability or software support has not been reviewed.
New staff have not received device-specific care training.

BOC Instruments offers repairs, preventive maintenance, installation and relocation support for ophthalmic equipment. Its service information states that loan equipment may be available for selected products, subject to stock, location and service needs.

Do not treat loan access as the full continuity plan. Identify which devices are essential for daily patient flow and document the temporary process for each likely failure.

How to Build a Service Log

A useful service log needs enough detail to guide action without becoming difficult to maintain.

Create One Record for Each Asset

Assign every instrument a unique asset number, including devices of the same model.

Record these fields:

Service-Log Field	Information to Capture
Asset identity	Internal asset number, device type, manufacturer and model
Equipment details	Serial number, purchase date and warranty status
Location	Site, room and department
Service contact	Supplier, technician or contract details
Maintenance schedule	User-check frequency and technical service interval
Last service	Date, type of work and service-report reference
Next service	Planned date and booking status
Calibration	Check date, result, person and certificate number
Fault history	Reported problem, error code, impact and action
Parts	Components replaced and relevant batch details
Return to use	Date, approval and any operating limits
Lifecycle status	Active, restricted, awaiting parts, retired or replaced

Define Who Can Close a Fault

A fault should remain open until the right person has confirmed the outcome. Staff may close minor user issues such as an incorrectly seated cable after testing normal operation. Calibration failures, internal repairs and clinical-performance concerns need technical review.

Use clear status labels:

Reported
Removed from use
Awaiting assessment
Awaiting parts
Under repair
Tested
Returned to use
Retired

Review Service Data Across Sites

Multi-site operators can review service logs each month or quarter. Useful measures include:

Percentage of assets serviced by their scheduled date
Number of open faults
Planned services compared with reactive repairs
Repeat faults by model
Days unavailable for clinical use
Instruments awaiting parts
Service spend by device and location
Equipment approaching the end of manufacturer support

These measures help teams set service priorities and prepare replacement budgets using recorded asset condition rather than age alone.

Frequently Asked Questions

How often should ophthalmic equipment be serviced?

The interval depends on the manufacturer, model, usage, age, clinical role and service history. Use the current instructions for use and the technician’s service schedule. An annual planning review can confirm whether each device is current.

Can clinic staff complete equipment servicing?

Staff can complete approved cleaning, visual inspections, basic operation checks and manufacturer-defined user tests. Internal repairs, technical adjustments and formal calibration should be handled by people with suitable training and equipment.

Does preventive servicing stop every breakdown?

No. Components can still fail without warning. Preventive work can identify wear, calibration changes and recurring faults before some problems cause a full interruption.

What should we do when a tonometer fails calibration?

Remove it from clinical use, label it, record the failed result and arrange technical assessment. Do not apply a correction figure to patient readings unless the manufacturer provides an approved method.

How can a clinic compare tonometer types?

The suitable measurement method depends on the clinical setting, portability needs, examination workflow and patient population. BOC’s Tonometer buying guide compares Goldmann, Perkins and Tono-Pen options to help clinical teams review their practical differences.

Is cleaning the same as preventive maintenance?

No. Cleaning controls visible contamination and supports infection-control procedures. Preventive maintenance may include internal inspection, alignment, lubrication, calibration, part replacement and performance testing.

Should equipment be checked after moving rooms?

Yes. Movement can affect physical setup, alignment, connections and table stability. The level of assessment depends on the instrument and the manufacturer’s relocation requirements.

What information does BOC need for a service enquiry?

Provide the equipment type, brand, model, serial number, clinic location, fault description, error codes and recent service history. Photos of damage or error screens may help the service team review the next step.
