The RTVue XR with Normative Database is an optical coherence tomography system indicated for the in vivo imaging and measurement of the retinal nerve fiber layer, and optic disc as a tool and aid in the diagnosis and management of retinal diseases by a clinician. The RTVue XR with Normative Database is also a quantitative tool for the comparison of retina, retinal nerve fiber laver, and optic disk measurements in the human eye to a database of known normal subjects. It is intended for use as a diagnostic device to aid in the detection and management of ocular diseases.
Device Story
RTVue XR is an ophthalmic imaging system using low coherence interferometry to capture cross-sectional images of cornea, anterior chamber, and retinal tissue. Device utilizes a line-scan camera to acquire A-scan sequences at ~70,000 A-lines per second. Operated by clinicians in clinical settings, the system processes reflectivity data to generate structural images and quantitative measurements. Output is displayed via a graphical user interface for clinician review. Comparison against a normative database aids in detection and management of ocular diseases. Faster image acquisition compared to predecessor reduces scan time while maintaining equivalent imaging results. Cornea scanning requires attachment of a specific lens module (CAM).
Clinical Evidence
Bench testing only. Comparison of RTVue XR against predicate RTVue with NDB demonstrated equivalent imaging performance. Safety and stability verified per IEC 60601-1 (Amendments 1 and 2) and IEC 60601-1-2.
Technological Characteristics
Non-invasive OCT imaging system; low coherence interferometer; computer-controlled; ~70,000 A-lines/sec acquisition speed; includes Cornea Anterior Module (CAM) for anterior segment imaging; graphical user interface for image acquisition and analysis; complies with IEC 60601-1 and IEC 60601-1-2 standards.
Indications for Use
Indicated for in vivo imaging and measurement of retinal nerve fiber layer and optic disc in humans to aid clinicians in diagnosis and management of retinal and ocular diseases; includes quantitative comparison of retina, retinal nerve fiber layer, and optic disc measurements against a normative database.

The RTVue XR with Normative Database is an optical coherence tomography system indicated for the in vivo imaging and measurement of the retinal nerve fiber layer, and optic disc as a tool and aid in the diagnosis and management of retinal diseases by a clinician. The RTVue XR with Normative Database is also a quantitative tool for the comparison of retina, retinal nerve fiber laver, and optic disk measurements in the human eye to a database of known normal subjects. It is intended for use as a diagnostic device to aid in the detection and management of ocular diseases.
## Technological Characteristics
The RTVue XR is a non-invasive diagnostic device for imaging the cornea, anterior chamber, and retinal tissue structure with micrometer range resolution. The RTVue XR OCT is based on the same Optical Coherence Tomography (OCT) technology used in its predicate device, RTVue with NDB OCT.
The RTVue XR is a computer controlled ophthalmic imaging system. The device scans the patient's eye using a low coherence interferometer to measure the reflectivity of the retinal tissue. The cross sectional retinal tissue structure is composed of a sequence of Ascans. It has a traditional patient and instrument interface like most ophthalmic devices. The computer has a graphic user interface for acquiring and analyzing the image.
RTVue XR offers three scan types: Retina, Glaucoma, and Cornea. For the Cornea scan, a lens must be attached to the front of the device for proper scanning. This lens is called the CAM (Cornea Anterior Module-cleared under K111505)
The upgrade of the line scan camera is designed to provide faster image acquisition. The RTVue XR is an updated version of RTVue with NDB that operates at ~70,000 A-lines per second while the RTVue-100 operates at ~27,000 A-lines per second. The RTVue XR machines will be equipped with new line-scan cameras capable of operating at ~70,000 Alines per second while delivering equivalent imaging results as the older generation RTVue line-scan cameras operating at ~27,000 A-lines per second.
## Performance Data
Elliot lab Certification Testing and Report (ref: R64363 Rev.3 and R63863 Rev. 4) in accordance to IEC 60601-1 Amendment 1 and 2 and IEC-60601-1-2. In addition a Bench test was also performed, with the results for comparison of the RTVue XR with the predicate device RTVue with NDB. The RTVue XR meets the safety and stability requirements of IEC 60601-1and IEC-60601-1-2 as well as the bench test requirements results.
#### Substantial Equivalence
The RTVue XR has the same intended use and similar indications, principles of operation, and technological characteristics as the RTVue with NDB OCT. The minor difference in the RTVue XR OCT is a new line scan camera for faster image acquisition and this upgrade does not raise any new questions of safety or effectiveness. Performance data demonstrates that the RTVue XR is as safe and effective as RTVue with NDB OCT. Thus, the RTVue XR is substantially equivalent to its predicate devices.

Two short videos show you everything — or skip straight to the written tutorial if you'd rather read. You can reopen this any time from the Tutorial button in the top bar.
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.
