Ophthalmic Equipment Service — Level 2: Fault-Finding
From the bad image or wrong reading to the failed assembly: illumination, optics, measuring modules, OCT, lasers and data
Part of the program: Ophthalmic Equipment Service Engineer — program (8 h) →
Level 1 taught you to keep an eye clinic's instruments safe, clean and verified. Level 2 starts when the right lamp, a clean window and a reseated cable have not helped. This course teaches the engineer to turn a clinician's complaint into a repeatable test on a test eye or target, place the fault on the instrument's block map, and follow it through illumination, optics and mechanics, refraction, keratometry and tonometry modules, biometers and OCT scanners, treatment lasers, cameras, PCs and data links to the assembly that has actually failed - and then return the instrument to service with the checks, safety tests and records that prove it, while knowing exactly what belongs to the manufacturer.
The quote was for a mainboard. The supply had been failing for months.
- Mainboards, measuring heads and PC modules are condemned because they reported the error, while a tired power supply, a dusty position sensor or a flat backup battery upstream was the real cause.
- Instruments are 'corrected' with offsets, local LEDs, home-made filters or reset lamp counters, and the clinic goes on measuring and treating patients with numbers and light that no longer mean what they say.
- After a repair, refractometers, tonometers and lasers go back to patients without test-eye checks, output measurements, electrical safety tests or a record, and nobody can say whether the instrument was fit for use.

Curriculum
Turn a clinician's complaint into a reproducible test on a test eye or target, place the fault in the instrument's block map, separate suspects by swapping and isolating one thing at a time, and know which adjustments are yours and which go back to the manufacturer.free
22 min02Illumination: halogen and LED modules, supplies, housings, heat and filters
Trace a dim, uneven, flickering or dead light on a slit lamp, microscope or measuring instrument through the lamp, its socket and supply, the driver, the housing and its cooling, and the filters, and know which parts must stay original because they protect the patient's eye.22 min03Optical path and alignment: safe cleaning, fogging and fungus, misalignment, joystick, chin rest and motors
Locate dirt, fog or fungus in an optical path without opening what you should not, clean only what you are allowed to clean without harming coatings, recognise misalignment and its causes, and repair joysticks, bases, chin rests and motor drives down to the screw, sensor, gear or cable.22 min04Refraction, keratometry and tonometry: test eyes, calibration checks and typical faults
Verify auto-refractometers, keratometers and non-contact, rebound and applanation tonometers on their reference devices, separate a measurement fault from an alignment, optics, drive or patient problem, and keep verification apart from adjustment.23 min05Biometry and OCT: optical biometers, ultrasound A/B probes and OCT scanners
Separate patient, optical, light-source, reference-arm, scanner, camera and PC faults on optical biometers and OCT units, fault-find ultrasound A and B scan probes, protect the unique calibration data, and know which calibrations need the manufacturer's targets and authorisation.24 min06Ophthalmic lasers: YAG, SLT and photocoagulation, laser safety, aiming beam and energy checks
Work safely in a laser room under IEC 60825-1 and local rules, fault-find the safety chain, aiming beam, delivery system and energy output of YAG, SLT and photocoagulation lasers without ever defeating an interlock, and know where the manufacturer's work begins.24 min07Cameras, PCs, software and data: fundus cameras, licences, DICOM and EMR export, backups
Fault-find fundus camera capture, flash and image faults, treat the instrument PC as part of the device (batteries, BIOS, displays, touchscreens, firmware), report licence and software faults to the manufacturer with the right evidence, and keep exports, DICOM links and backups working without exposing patient data.22 min08Complex cases and return to service: performance checks, electrical safety, eye-contact parts, records and fitness for use
Work through multi-fault and intermittent ophthalmic cases with a written timeline, prove a repair with performance checks and electrical safety tests, check that eye-contact parts are safe to use and correctly reprocessed, and write a record that lets the hospital's responsible person decide on clinical use.24 min—Exam

FAQ
Is this manufacturer training?
No. It is independent, vendor-neutral training. It does not replace the manufacturer's service procedures, does not grant authorisation or access to service software, passwords, licences or calibration tools, and every repair must still be followed by the checks the manufacturer and national rules require.
Do I need Level 1 first?
Ophthalmic Equipment Service — Level 1 is the prerequisite: the instruments, light, laser and electrical safety basics, cleaning rules, test eyes and the first fault-finding habits are assumed here. Electronics and Power Supplies, Electrical Safety for Medical Equipment and DICOM, PACS and Networks are recommended alongside.
Will I work on lasers?
The course explains laser safety, the safety chain, aiming beam and output checks at the level of a field engineer working under local rules with the laser safety officer. Work inside the laser head, alignment and energy calibration are left to the manufacturer or authorised engineers. Interlocks are never defeated.
Does it teach board-level repair?
It teaches fault-finding to the assembly and the replaceable module. Some field cases end in a component repair; that is workshop work, covered in the Electronics and Power Supplies course.
What does the certificate say?
Your name, the course, the hours, the date and your exam score, with a unique number and a public verification page.
Can my company buy seats for a team?
Yes: five seats and a progress overview for the manager.
