## Intended Use
The EXCELSIOR Software is intended for use in importing, processing, measurement, analysis and storage of ophthalmic clinical images as well as in management of clinical data, through a computerized network for use in analysis of images and data obtained in clinical trials.
## Device Description
The EXCELSIOR software is a cloud-based software that provides a grading platform integrating remote data collection, quantitative analysis and measurement, storage and management of ophthalmic data and images for clinical trials.
EXCELSIOR provides secure access through user authentication and role authorization, and is adherent to HIPAA and CFR 21 part 11 requirements for clinical investigations. EXCELSIOR user accounts can only be initiated by EXCELSIOR administrators or project managers: administrators or project managers enter in user information, and the user is prompted by email to setup his own user name and password. Once setup, the user access is defined by its role associated with a particular trial. EXCELSIOR provides 128-bit secure network encryption and audit trail logging to ensure that changes to the data are retraceable and re-constructible.
## Performance Data
The EXCELSIOR Software has been tested and found in compliance with the following recognized consensus standard:
DICOM (Digital Imaging and Communications in Medicine) - Developed by the American College of Radiology and the National Electrical Manufacturers Association. Specifies the format for the communication of digital images between individual devices and over networks.
Additionally, software validation and verification tests were performed which confirmed that the software performed as intended.

## Technological Characteristics and Substantial Equivalence
The EXCELSIOR Software is intended for use in importing, processing, measurement, analysis and storage of ophthalmic clinical images as well as in management of clinical data, through a computerized network for use in analysis of images and data obtained in clinical trials. Both the identified predicate devices are ophthalmic image management systems intended for use in review and processing of ophthalmic images. Both EXCELSIOR and Synergy (K093313) are intended for use in importing, processing, measurement, analysis and storage of ophthalmic clinical images as well as management of data. Both systems receive the data through a computerized network. The differences between the intended uses primarily relate to the type of data being processed. In the case of EXCELSIOR, images and data related to subjects participating in a clinical trial is processed while Synergy processes data from patients in clinical practices. EyeKor believes that the similarity of the functions performed by the software products is sufficient to allow the intended uses to be determined to be similar.
-- --
The EXCELSIOR Software has very similar technological characteristics to the Forum and Synergy software programs. All of the software programs are client-server based applications with web-based viewing of ophthalmic images. All images are stored in a central database. All of the software programs are accessed from a PC using a Windows server operating system.
All of the software programs are built in a SQL database and support DICOM files for fundus photographs and OCT images. All of the systems support use of PDF files for reviewing ophthalmic reports. All of the systems allow the user to search for records related to a particular patient. One of the differences between the EXCELSIOR Software and the predicate devices is that images and reports accessed in the EXCELSIOR Software are accessed using subject identification numbers while Synergy and Forum access records based on the patient's name or other identifiable information. Since EXCELSIOR is used in a clinical trial environment this type of access is required.
In regards to measurements that may be made with the software programs, EXCELSIOR performs distance measurements, area measurements, ETDRS grid measurements, OCT layer thickness measurements, and macular grid summary. These are the same measurements performed by Synergy.
Therefore, the technological characteristics of the EXCELSIOR Software program are similar to the identified predicate devices.
{3}------------------------------------------------
In summary, the company's EXCELSIOR Software has a similar intended use as the previously cleared predicate devices. In addition, the EXCELSIOR Software has similar technological characteristics and principles of operation as its predicates. Although there are differences between EXCELSIOR and its predicate devices, those differences do not raise new questions of safety or effectiveness. Thus, the EXCELSIOR Software is substantially equivalent.

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.
Try it yourself
Head to the search page and work through a few of these AI/ML fuzzy searches to build intuition: perivascular fat on CT · aortic valve calcification opportunistic screening on noncontrast CT · breast cancer prediction on digital pathology slides · autism detection · gestational age prediction · a hearing aid that can also detect a pulse · foundation model based analysis of ECG · large language models · penetration test. Watch how the relevance scores, intended use, and AI Performance tables tell you when results stop being meaningful.
