Retrospective clinical data analysis of iCare IC200 IOP measurements
Retrospective analysis was used to compare the performance of the new 'Quick Measure' feature against clinical data from the predicate device to demonstrate substantial equivalence and adherence to ANSI Z80.10:2014 performance goals.
Retrospective clinical data analysis of Quick Measure function; Retrospective clinical data analysis
Human eyes (N=149 total); Sample Size: 149 eyes
GAT reference tonometer (Sitting) and Perkins reference (Supine)
Accuracy within ±5 mmHg vs. GAT/Perkins reference
Indications for Use
The iCare IC200 tonometer is intended to be used for the measurement of intraocular pressure of the human eye.
Device Story
Hand-held, battery-operated rebound tonometer; measures intraocular pressure (IOP) without topical anesthesia. Device uses sterile, single-use probe that makes brief contact with eye; measures probe deceleration and rebound time to calculate IOP. Deceleration is slower at low IOP; faster at high IOP. Operated by healthcare professionals in clinical settings. Features 'Quick Measure' mode (2-3 measurements) and 'Default' mode (6 measurements). Provides IOP readings to clinicians to assist in clinical decision-making. Benefits include rapid, non-invasive IOP assessment across various patient positions (horizontal to supine).
Clinical Evidence
Retrospective clinical data analysis compared 'Quick Measure' mode to predicate IC200 data (N=149 eyes). Performance evaluated against GAT (sitting) and Perkins (supine) reference tonometers. Results showed high agreement: 0.0% to 6.2% of measurements outside ±5 mmHg across low, medium, and high IOP subgroups. Bench testing using manometrically controlled artificial cornea confirmed high agreement with manometric pressure and default measurement mode, regardless of operator or angle.
Indicated for measurement of intraocular pressure in human eyes by healthcare professionals.
Regulatory Classification
Identification
A tonometer and accessories is a manual device intended to measure intraocular pressure by applying a known force on the globe of the eye and measuring the amount of indentation produced (Schiotz type) or to measure intraocular tension by applanation (applying a small flat disk to the cornea). Accessories for the device may include a tonometer calibrator or a tonograph recording system. The device is intended for use in the diagnosis of glaucoma.

## 1.4 Indications for Use / Intended Use
"The iCare IC200 tonometer is intended to be used for the measurement of intraocular pressure of the human eye."
The intended use of the iCare IC200 tonometer remains unchanged by this design modification.
## 1.5 Device Description
The iCare IC200 tonometer (model TA031) is a hand-held, battery-operated device which measures intraocular pressure (IOP) without the need for topical anaesthesia by rebound tonometry. The tonometer is to be used by a healthcare professional.
The tonometer uses the rebound method. A small and light, sterile, single-use probe makes brief contact with the eye. The device measures the deceleration of the probe and the rebound time and calculates the IOP from these parameters. Deceleration of the probe is slower at low IOP compared to high IOP. The measurement method, the IOP measurement algorithm and rebound technology (including disposable probe) are identical with the predicate device.
iCare IC200 tonometer can obtain IOP measurements in all angles between horizontal and supine directions. External design has not been modified. The user interface menu has been updated to contain a Quick Measure mode. The new Quick Measure feature is used to measure patient's IOP with fewer rebound measurements and faster measurement cycle. Quick Measure takes two or three rebound measurements; two if both results are within 2 mmHg and third if the difference between the first two measurements is greater than 2 mmHg.

## Table 3 Comparability Chart between IC200 Quick Measure and GAT, and Perkins, within IOP subgroups
Accuracy of the iCare IC200 quick measure mode was assessed in a bench test using a manometrically controlled artificial cornea. Testing compared the new Quick Measure mode against the existing default measurement mode (same as in predicate device IC200), clinically validated subnormal reference tonometer (iCare IC200), and manometric pressure.
Repeatability and accuracy testing completed with iCare IC200 quick measure mode demonstrated high agreement with manometric pressure and reference tonometer used in default measurement mode (iCare IC200).
Reproducibility test completed with iCare IC200 quick measure mode demonstrated high agreement with manometric pressure regardless of the device, operator, or the measurement angle.
{10}------------------------------------------------
## Software Verification and Validation
Testing Software verification and validation testing were conducted, and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "Moderate" level of concern, since a failure or latent flaw in the software could indirectly result in minor injury to the patient or operator through incorrect or delayed information or through the action of a care provider.
## 1.8 Substantial Equivalence
The modified iCare IC200 including the Quick measure mode is substantially equivalent to the predicate device. The devices have the same or substantially equivalent technological characteristics and the iCare IC200 raises no new issues of safety and effectiveness. Performance and safety data demonstrate that the modified iCare IC200 is as safe and effective as the predicate device.

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.
