Two used slit lamps with the same model name may be offered with different accessories or illumination configurations. Before comparing prices, ask for a clear description of the actual unit and the components included in the sale.
1. Identify the instrument and its configuration
Request the model, serial number, photographs of the labels, and an itemized component list. Confirm the eyepieces, available magnifications, illumination type, and supplied power unit against documentation for that configuration.
For example, Haag-Streit’s accessory information lists optional eyepieces and LED upgrade packages for specific models. This illustrates why a model name alone does not establish which options a used instrument has. Confirm any upgrade on the actual unit rather than assuming it from a current brochure.
2. Ask what was checked in the optics and illumination
Have the seller describe the inspection and any service performed. Ask about the condition of the viewing optics, illumination controls, filters, and slit adjustment. Request clarification of any visible damage or known limitation.
Arrange for a qualified person to evaluate the instrument using the manufacturer’s instructions. Photographs and a video can help identify questions, but they do not replace an appropriate functional assessment or the checks required before clinical use.
3. Review movement and positioning
During a demonstration, ask to see the base movement, joystick operation, height adjustment, and applicable locks. Have the intended examiner assess whether the setup works comfortably with the planned chair and table.
Include the patient support assembly in the discussion: ask what chin rest, forehead rest, and related components are supplied. If the instrument will replace one on an existing table, obtain confirmation of the mounting requirements before ordering.
4. Treat accessories as separate line items
List any tonometer, mounting hardware, camera, beam splitter, observation attachment, or table shown in the photographs. Ask which items are included and which are pictured only to demonstrate a possible setup.
Have the relevant supplier confirm compatibility by exact model and part number. If imaging is part of your plan, ask separately about the camera, computer, software, licenses, and support. Do not count a photographed camera as a complete working imaging package without confirmation.
5. Compare what it takes to put the unit into service
Request the applicable manual and confirm delivery, assembly, installation, and any staff instruction arrangements. Ask for the warranty terms in writing, including the process for reporting a problem and arranging service.
A useful comparison sheet has one column for each proposed unit and rows for configuration, included accessories, documented inspection, installation requirements, and total quoted cost. Mark unanswered items as questions rather than treating them as included.
