## Purpose of 510(k) Submission:
#### ~ New Technology ~
The SynergEves® SiH (petrafocon A hem-larafilcon A) Hybrid Daily Wear Contact Lensescleared under 510(k) K083921 and K113586-are modified to include Hydra-PEG Technology (HPT), which is a thin, polyethylene glycol (PEG)-based polymer designed to improve the wettability of the contact lenses. Specifically, HPT treated contact lenses demonstrate a measureable improvement in the contact angle in comparison with the untreated lenses. The application of HPT to the surface of SynergEyes® SiH contact lenses does not change the design or indications for use in comparison with the untreated lenses, the predicate device (K083921 and K113586).
#### Predicate Devices:
The SynergEyes® SiH with Hydra-PEG (petrafocon A hem-larafilcon A) Hybrid Daily Wear Contact Lenses are substantially equivalent to the following predicate devices:
> "SynergEyes® SiH (petrafocon A hem-larafilcon A)" By SynergEyes, Inc. 510(k) number; K083921 and K113586 -primary predicate
"IntelliWave4 with HPT (safrofilcon A)" by Art Optical Contact Lens, Inc. 510(k) number; K152046 -reference predicate
"UltraHealth® SiH (petrafocon A hem-larafilcon A)" By SynergEyes, Inc. 510(k) number: K142510 -reference predicate
#### Device Description:
The SynergEves® SiH with Hydra-PEG Hybrid Daily Wear Contact Lens is a combination of high Dk rigid gas permeable contact lens-at the central optical portion of the lens corresponding to the cornea-and soft hydrophilic silicone-hydrogel skirt-straddling the limbus of the eye peripherally. The lenses are manufactured by lathe cutting process for custom Rx, and fabricated from petrafocon A (rigid, central portion) and hem-larafilcon A (soft, peripheral portion). The soft skirt is comprised of silicone hydrogel copolymer (hem-larafilcon A). The lens consists of 28% water and 72% (petrafocon A and hem-larafilcon A). The (petratocon A and hem-larafilcon A) names have been adopted by the United States Adopted Names Council (USAN). When placed on the human cornea, the SynergEyes® SiH with Hydra-PEG Hybrid Daily Wear Contact Lens acts as a refractive medium to focus light rays onto the retina.
The SynergEyes® SiH with Hydra-PEG Hybrid Daily Wear Contact Lens incorporates a violet visibility tint in the rigid gas permeable center, and a UV absorber. The device is available in the spherical, aspheric, multifocal (progressive), post-surgical, & irregular cornea design configurations

| • Power Range (sphere) | -25.00D to +25.00D |
| • Add Power | +1.00D to +4.00D |
The Physical properties of the lens are:
| | RGP Center | Soft Skirt |
|---------------------------------------------------|-------------|-------------|
| Refractive Index (wet) | 1.442 | 1.435 |
| Luminous Transmittance<br>(tinted) (380nm to 780) | 87% | 97% |

| Oxygen Permeability<br>(revised Fatt method) | 130 | 84 |
The SynergEyes® SiH with Hydra-PEG Hybrid Daily Wear Contact Lens is treated to incorporate Hydra-PEG Technology (HPT)-which is a thin polyethylene glycol (PEG)-based polymer that is covalently (permanently) bonded to the surface of the contact lens and is designed to enhance the surface properties of the contact lens while retaining the mechanical properties of the underlying material. When treated with HPT, the underlying material (petrafocon A hem-larafilcon A) is encapsulated in a thin layer of polymer that results in measurable improvement of wettability (dynamic contact receding angle) compared to untreated lenses. The resulting layer is hydrophilic and approximately 30nm in thickness. The following table depicts the enhanced contact angle of the SynergEyes® SiH with Hydra-PEG Hybrid Daily Wear Contact Lens versus the predicate device:
| Wettability -- captive bubble contact angle (degrees) (advancing contact angle)* | | |
|----------------------------------------------------------------------------------|---------|-------|
| Lens | Average | Stdev |
| SynergEyes® SiH with Hydra-PEG (New Device) | 21.75° | 2.2 |
| SynergEyes® SiH (Uncoated) (Predicate Device) | 33.50° | 9.5 |
* Hydra-PEG coated lenses demonstrate a 35% improvement in wettability vs. uncoated lenses (n = 20). Statistically significant difference for mean contact angle with respect to lenses had a lower average contact angle than the un-coated lenses (ANOVA, p=0.000)
The lens is supplied sterile in vials containing a buffered saline solution. Vial labeling is printed with appropriate lot numbering, expiration dating and lens parameter identification. Expiration dating has been established based on studies of product stability, package integrity, and validation of the sterilization process.

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

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.
