Name of Device: VX130 ophthalmic diagnostic device Common name: Ophthalmic diagnostic device Classification: tonometer , AC powered Regulatory class: II Product code: HKX Requlation number: 886.1930
#### III. PREDICATE DEVICES
The VX130 is claimed to be substantially equivalent to the following currently marketed devices:
#### . VX120 Ophthalmic Diagnostic Device
Manufacturer: LUNEAU SAS FDA K143086 issued June 1, 2015. Product code: HKX
### . CM3910 ROTATING DOUBLE SCHEIMPFLUG CAMERA (Galilei G4)
Manufacturer: SIS LTD. SURGICAL INSTRUMENT SYSTEMS Allmendstrasse 11 Port Bern, SWITZERLAND CH - 2562 FDA K051940 issued July 15, 2005. Product code: MXK
The VX130 is equivalent to VX120 for tonometry and pachymetry functions and other functions not subject to 510(k) : combined wave front aberrometer, corneal topographer and retroilluminator. It is equivalent to CM3910 for its pachymetry function.
{4}------------------------------------------------
#### DEVICE DESCRIPTION IV.
The VX130 is a multifunctional ophthalmic diagnostic device.
The VX130 combined wavefront aberrometer, corneal topographer, cataract screening device, Scheimpflug pachymeter, and non-contact tonometer is a single platform that contains five different measurement units.
The wavefront aberrometer works on the Shack-Hartmann principle and is used as an advanced autorefractometer that measures both lower and higher order aberrations of the eye. Retro illumination is used to image ocular opacities. The corneal topographer uses a Placido disk to measure keratometry and the detailed shape of the cornea. A linear scanning Scheimpflug pachymeter measures the thickness of the cornea by illuminating it with a slit of light and photographing it using the Scheimpflug technique. Anterior and posterior corneal shape are also measured from the Scheimpflug images. An air puff non-contact tonometer is included for measurement of the intraocular pressure. The device is fully automated and a number of different measurements can be performed by a single command including alignment and focusing.
#### V. INDICATIONS FOR USE:
The VX130 is a multi-function diagnostic device combining wavefront aberometer, corneal topographer, retro-illuminator, tonometer and pachymeter, indicated for:
Measuring the refraction of the eye giving both lower and higher order aberrations Measurement of the shape of the cornea
- Retro-illumination imaging of the eye
Measuring the intraocular pressure without contacting the eye for glaucoma evaluation Photographing the eye and taking images of the eye to evaluate the thickness of the central cornea.
- Full cornea thickness map
- Scheimpflug imaging
- Anterior chamber imaging
- Pupil image
- Image of the cornea relative to the iris
{5}------------------------------------------------
- VI. COMPARISON OF INTENDED USE AND TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICES
### Comparison with VX120
The VX130 has same hardware as VX120. The difference is that VX130 provides multi-slits of the Scheimpflug camera resulting of multiple results of the same indication in different place in the cornea as well as additional maps, while VX120 provides only one Scheimpflug image. That doesn't affect indications for use below:
"Indications for use:
The VX120 is a multi-function diagnostic device combining wavefront aberometer, corneal topographer, retro-illuminator, tonometer and pachymeter, indicated for: Measuring the refraction of the eye giving both lower and higher order aberrations Measuring the shape of the cornea Retro-illumination imaging of the eye Measuring the intraocular pressure without contacting the eye for glaucoma evaluation Photographing the eye and taking images of the eye to evaluate the thickness of the cornea."
This variant doesn't impact on performances and safety. VX130 is not different in safety or efficacy, and is substantially equivalent to VX120
### Comparison with Galilei
Indications for use:
The pachymeter function of the VX130 has the same intended use as the Galilei G4 for photographing the eye and taking images of the eye to evaluate the thickness of the central cornea.

### Rationale for Substantial Equivalence
The pachymeter function of the VX130 has the same intended use as the Galilei G4 for photographing the eye and taking images of the anterior segment of the eye to evaluate the thickness of the cornea.
The Galilei G4 and the VX130 systems are based on the Scheimpflug Principle for slit image photography. The measurement systems use blue light (UV-free) through a slit to illuminate the eye, and a Camera for photography. The devices take a series of images of the anterior segment of the eye and analyse the images.
- The devices have the same intended use
- The devices utilize the same measuring principles (Slit Scan)
- The devices utilize the same photographic medium
- . Similar measurement wavelengths are used
The devices use the same features like a
- Head stabilizing device
- . Fixation target
- All devices are considered "non-invasive" as defined in 21 CFR §812.3(k)
The VX130 for all functions other than pachymetry is identical to the VX120
#### Safety
The VX130 is a non-invasive diagnostic system, which contacts the patient only on his/her chin and forehead. The VX130 does not present or pose any new or additional risks for the prescribed intended uses. The light output is of an eye safe intensity and wavelength. The electrical safety requirements for medical devices are met. The VX130 is proven effective for its intended uses through internal performance tests.
The following performance data were provided in support of the substantial equivalence determination:
- 1. Electrical safety and EMC testing were conducted on the VX130. The device complies with IEC60601-1:2006, and the IEC60601-1-2 for EMC.
- 2. Software verification and validation testing was done according to IEC62304.
{7}------------------------------------------------
- 3. Risk management: VX130 was evaluated according to ISO14971: 2012. All risks have been reduced to safe levels thus there is no conflict between risk and benefit.
- 4. Tests for ophthalmic products: VX130 was evaluated in accordance with ISO15004-1:2009 and ISO15004-2:2007 standards and was found to meet all requirements of the standards.
- 5. For optical hazards, VX130 was evaluated in accordance with IEC60825-1: 2008: the result is VX130 is laser class 1.
### Tests for pachymetry:
- 1. A comparison study of anterior segment parameters done with VX130 and Galilei G4 shows that there are only small differences between the devices. Table 1 shows the differences between the two devices for a range of anterior segment parameters. Table 2 shows a repeatability measurement of the VX130. There is not a significant difference between the repeatability measurement and the comparison measurement. The two devices can therefore be considered equivalent.

Part 1 — Search, results, and everyday workflows 16 min
Part 2 — Embeddings: the galaxy map 3 min
1. Search: exact and fuzzy
Type a phrase like "coronary artery calcification" into the search box. You get two kinds of results. Exact results match the literal phrase — prefix searches work ("coronary artery calcificati") but suffix searches do not. Fuzzy results match on the meaning and intent of your phrase rather than the exact words, and are sorted by relevance score. Hover over the Exact or Fuzzy badge on any row to see exactly why it matched.
Use the checkboxes above the results to narrow: SaMD keeps only software-only devices, AI / ML keeps only devices with AI.
Exact vs. fuzzy search: what's the difference?
Exact matches on the literal phrase (prefix search works, suffix does not). Fuzzy matches on the meaning and intent of the phrase rather than the exact words. Hover over the badge on any row to see why it matched.
You search "coronary artery calcification" and want only software devices with AI. What two filters do you apply?
Narrow by SaMD (software-only devices), then narrow by AI/ML (devices with AI).
2. The results table
Scroll right in the results table. The intended use is extracted for you — no need to open the PDF. The device story gives a high-level snapshot of what the device does and how it's used. The AI Performance sub-table shows each output name, acceptance criteria, observed values, and development/test dataset descriptions — the same format Innolitics uses for regulatory strategy outputs, and the fastest high-level fingerprint of an AI device. It is AI-generated but has been very reliable in practice.
Where do you find a device's intended use without opening the PDF?
Scroll right in the search results table. The intended use column is extracted for you; no need to dig into the 510(k) summary PDF.
What does the AI Performance sub-table show, and why is it useful?
Output name, acceptance criteria, observed values, development dataset description, and test dataset description. It's the same format we use for regulatory strategy output and Fast 510(k) input, and the fastest high-level fingerprint of an AI device. AI-generated but reliable in practice.
3. Judging fuzzy relevance
Fuzzy results trail off in relevance as you scroll. Use three signals to decide how far down to go: the fuzzy badge explanations, the intended use column, and whether your target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, you're past the relevant zone. A top hit with a low score (~0.4) and a stretched explanation is a hint the closest predicates are far away — the project may be headed for De Novo. Note the fuzzy search is a pattern match: it doesn't handle negation ("not") well, and hardware devices can appear — filter by SaMD/AI ML to cut them.
How do you judge how far down fuzzy search results to go?
Use the relevancy signals: the fuzzy badge explanations, the intended use column, and whether the target output (e.g., Cobb angle) still appears in the AI Performance sub-table. Once it stops appearing, results are trailing off in relevancy.
4. Device detail page: chat and citations
Click a device name to open its detail page: device facts on the left, a chat window on the right. Ask something like "Describe the training data". The answer carries little citation bubbles — click one to jump to the highlighted passage in the source PDF, so you can verify every AI answer against the document. There's also a Download PDF button for sharing.
How do you verify an AI chat answer on the device detail page?
Click the citation bubbles to jump to the relevant highlight in the source document.
Reading rule for every project: how many summaries do you read in full?
At least the three most relevant 510(k) or De Novo summaries, in full. After that, use targeted chat questions to confirm your memory quickly. The tool supports this professional habit — it doesn't replace it.
5. Side-by-side comparison
Select multiple rows in the results table (aim for under ~10), then open the PDF Viewer tab. Ask one question — it goes to all selected devices in parallel, each with citations. This is the fastest way to compare and contrast devices: training data, PCCP scope, how they handled adding new scanners, and so on.
What does the side-by-side PDF viewer mode do?
Select multiple devices, open the PDF viewer tab, and ask one question (e.g., "Describe the training data"). It queries all selected devices simultaneously with citations, so you can compare and contrast quickly.
6. Collections
With rows selected, go to the Collections tab and create a labeled collection (e.g., "Cobb Angle Project"). Reload that selection any time — before a client call, pull up the collection and ask questions across all of its devices at once.
How do you save a set of selected devices for later use?
Select the rows, go to the Collections tab, and create a labeled collection (e.g., "Cobb Angle Project"). You can reload the selection anytime and carry it into the PDF viewer and other tabs that support selections.
7. Product codes and the regulations tree
Click a product code in the results to jump to it in the regulations tree — identification text, sibling product codes, and devices you can open in a PDF viewer on the right. Click a regulation number to see its identification, special controls, and related product codes. You can also search by product code or regulation number at the top of the tree. Always read the special controls if any exist for your device — it broadens your search and sharpens pre-kickoff research.
What can you do from the regulations tree view?
Browse product codes and regulation numbers, read the identification text and special controls, browse sibling product codes, open device PDFs on the right, and search by product code or regulation number at the top of the tree.
8. Chart view
Click Show Chart and segment by regulation number (or product code) to see which regulations dominate your result set. Clicking a regulation takes you into the regulations tree. Great for spotting that most matches are, say, hardware laparoscopic devices — a cue to go back and filter.
How do you see which regulations dominate a search result set?
Click "Show Chart" and segment by Regulation Number. Clicking a regulation takes you to the regulations tree.
9. The predicate graph
Open the Predicates tab for a family-tree view of predicate relationships. Click a node to trace its parents and children; selections from search carry over pre-selected. Commonly predicated devices are worth reading — a lot of people predicated them for a reason. The visual lineage is also handy on client calls, e.g. to show how a predicate family evolved and justify why your predicate still holds.
In the predicate graph, why are commonly predicated devices worth reading?
A lot of people predicated them for a reason. Clicking a node traces parents and children, and selections from search carry over pre-selected.
10. Embeddings: the galaxy map
The Embeddings tab plots every matching document in a 2-D "galaxy map" where semantically similar devices cluster together. Hover or click clusters to explore, and let AI label the clusters for you. Embeddings beat product codes for grouping: two devices can carry different product codes (LLZ vs. QIH) yet do the same thing — the embedding captures the meaning of the intended use and device story. This is also exactly how retrieval-augmented generation (RAG) works under the hood, and it makes a great visual on client calls.
