### Description of Device:
The Welch Allyn iExaminer is comprised of the adapter, the iPhone and the software application. The adapter is specifically designed to hold the iPhone 4 and iPhone 4S in a fixed position in order to align the camera in the iPhone with the optics of the Welch Allyn PanOptic.
The software application allows the user to capture, store, send, and retrieve images of the eye as seen through the PanOptic. With the Retinal image application, iExaminer Professional Version, the user has the ability to capture images of the patient's eye by activating the camera icon at the iPhone tool bar. Additional icons, buttons and pages allow the user to save images, transfer images and retrieve previously saved images.
### Indications for Use:
The iExaminer is an attachment and software used only with the iPhone 4S in conjunction with the Welch Allyn PanOptic Ophthalmoscope to allow users to capture, send, store and retrieve images of the eye. The device is intended to be used by trained personnel within a medical or school environment.
### Technological Characteristics:
The PanOptic is not being changed. None of the technological characteristics and indications for use of the PanOptic are being changed.
The Welch Allyn iExaminer is composed of two components that are used in combination and in conjunction with the PanOptic. The adapter is a plastic bracket that aligns the optics of PanOptic with the camera of the iPhone 4 and iPhone 4S. The software that can be purchased along with the adapter allows the user to document images of the patient's eyes.
The software allows the user to capture images of the Retinal Image button. Next the user can view these images and select the ones to save. The user can name the images for later retrieval. Also, if the iPhone is configured and the user is using the Professional version of the iExaminer software application they can print or email saved images.
The software Application itself has two version and a Professional version. The Free version only allows the user to save ten patient files and does not allow them print or Email the images. These are the only differences between the Free and Professional versions of the iExaminer software.
### Non-Clinical Tests:
Verification and validation were conducted to ensure expected performance of the Welch Allyn iExaminer, compliance to applicable standards, and to demonstrate that it does not affect the functionality or performance of the PanOptic. The Welch Allyn iExaminer is an ophthalmic camera that allows the user to document images of the eye as seen through the PanOptic.
The following FDA Guidance and standards were applied to the modified device.

### Device Comparison Tables
### Overall Comparison.
The 510(k) consists of using the Welch Allyn iExaminer in conjunction with the PanOptic. The Welch Allyn iExaminer compares favorably to the predicate devices listed above in terms of technology, Intended use and Indications for use. The information in the tables below were obtained from 510(k) summaries found on the FDA database along with information obtained from the respective device websites.
### Substantial Equivalence Discussion
The Welch Allyn iExaminer is substantially equivalent in intended use and technology. Like the predicate devices classified in product code HKI, the Welch Allyn iExaminer has a camera with the ability to digitally capture images of the eye along with the ability to store images on the device itself. Also, as with the predicates classified as HKI, the Welch Allyn iExaminer has the ability to electronically send/transfer these images to other Information Technology Equipment (e.g., personal computer). The Welch Allyn iExaminer transfers these images via email. The predicate devices transfer the images via a USB. As with the predicate devices, images on the Welch Allyn iExaminer can be retrieved for viewing at a later time.
As part of the clinical study, the electronic transfer of images by the Welch Allyn iExaminer and the subsequent downloading to a Personal computer were compared to the Optomed images that were electronically transferred and downloaded to the same personal computer. The transferred images were determined to be at least as accurate and adequate (carry sufficient imaging details) to discern important clinical information as the predicate Optomed device, and thus substantially equivalent.
The iPhone does not impart any energy into the eye as part of the iExaminer. The energy released into the eye by the Welch Allyn iExaminer is the same as the Welch Allyn PanOptic. The light source for the iExaminer is the Halogen bulb used by the PanOptic, i.e., no additional light source beyond the PanOptic's halogen bulb is utilized by the iExaminer. In addition, the Welch Allyn iExaminer has been tested and found to be in compliance to applicable industry standards.
### Summary of Device Performance Confirmed by Bench Testing
Several bench tests were completed to confirm the device is substantially equivalent, based on standards, to the predicate device.
### Summary of Device Performance Confirmed by Clinical Testing
As noted above, testing was conducted to confirm that the Welch Allyn iExaminer performed as intended to capture images that have sufficient detail to allow a trained professional to discern clinically important information.

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.
