The UltraVue/P, UltraVue/C (hioxifilcon B) Soft (Multifocal) Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and are presbyopic. The lens may be worn by persons who may exhibit astigmatism of .75 diopters or less where the astigmatism does not interfere with visual acuity.
Device Story
UltraVue/P and UltraVue/C are daily wear soft multifocal contact lenses fabricated from hioxifilcon B. Lenses are lathe-cut from dry blanks and become soft/pliable when hydrated in aqueous solution. They function as a refractive medium to focus light from distant, intermediate, and near objects onto the retina, compensating for refractive error. Used by patients with myopia, hyperopia, and presbyopia; prescribed by eye care professionals. The device provides a transparent optical surface over the cornea. Benefits include improved visual acuity across multiple distances for presbyopic patients.
Clinical Evidence
No clinical data provided. Substantial equivalence is based on bench testing, manufacturing/chemistry data, and comparison of physical properties (water content, oxygen permeability, refractive index) to predicate devices.

Device Information:
| Device Classification: | Class II |
|------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------|
| Classification Number: | LPL |
| Classification Name: | Lenses, Soft Contact, Daily Wear |
| Trade Name: | UltraVue/P, UltraVue/C (hioxifilcon B) Soft<br>(Multifocal) Daily Wear Contact Lens (Clear & Blue<br>Visibility Tint, Lathe-cut from Lens Blank) |
{1}------------------------------------------------
#### Equivalent Devices:
The UltraVue/P, UltraVue/C (hioxifilcon B) Soft (Multifocal) Daily Wear Contact Lens is substantially equivalent to the following prodicate devices in terms of intended use and design. Prodicate devices include: the Bi-Soft manufactured by Lombart Lenses, the LifeStyle 4-Vue and LifeStyle Xtra manufactured by The LifeStyle Co., the Horizon 55 Bicon manufactured by Westcon, the Ocu-Flex-53 manufactured by Ocu-Ease Optical, the SimulVue manufactured by Unilens Corp and the BENZ-G 3X manufactured by BENZ Research and Development Corp.
## Device Description:
The Ultra Vue/P, Ultra Vue/C (hioxifilcon B) Soft (Multifocal) Daily Wear Contact Lenses are fabricated from hioxifilcon B. which in the dry (unhydrated) state may be machined and polished. The hydrophilic nature of this material allows the lens to become soft and pliable when immersed in an aqueous solution.
In the hydrated state, the lens conforms to the curvature of the eye covering the cornes and extending slightly beyond the limbus forming a colorless, transparent optical surface. The (hioxifileon B) soft hydrophilic contact lens has a spherical back surface. The hydrophilic properties of the lens require that it be maintained in a fully hydrated state in a solution compatible with the eye. If the lens dries out, it will become hard appear somewhat wareed: however, it will return to its proper configuration when completely rehydrated in the proper storage solution.
The hydrophilic characteristics allow aqueous solutions to enter the lens and in its fully hydrated state the lens is approximately 48% water by weight. The physical properties of the lens are:
| Refractive Index | 1.515 (dry) 1.404 (hydrated) |
|-----------------------------|------------------------------------------------------------------------|
| Color Pigment Name | Phthalocyanine Blue |
| Light Transmission (clear) | greater than 95% T |
| Light Transmission (tinted) | greater than 95% T |
| Water Content | 48 % ±2% |
| Specific Gravity | 1.308 (dry) 1.136 (hydrated) |
| Oxygen Permeability | 15 X 10-11 (cm2/sec) (ml O₂/ml x mm Hg @ 35°C), (revised Fatt method). |
#### Intended Use:
The UltraVue/P, UltraVue/C (hioxifileon B) Soft (Multifocal) Contact Lenses for daily wear are indicated for the correction of visual acuity in aphakic and not aphakic persons with non-diseased eyes with myopia or hyperopia and are presbyopic. The lens may be worn by persons who may exhibit astigmatism of .75 diopters or less where the astigmatism does not interfere with visual acuity.
{2}------------------------------------------------
#### Substantial Equivalence:
The device will be manufactured according to specified process controls and a quality assurance program. The device will undergo manufacturing, packaging and sterilization procedures similar to devices currently marketed and distributed by Les Laboratories Opti-Center Inc. The established safety profile (pre-clinical toxicology and manufacturing/chemistry data) of the device is equivalent to the BENZ-G 3X, 510(k) #K964528. Being similar with respect to indications for use, materials, physical construction and safety & effectiveness to the predicate devices, this meets the requirements per section 510(k) of the act regarding substantial equivalence and does not raise different questions of safety and effectiveness than the predicate devices identified above.
The following matrix illustrates that the production method, lens function and material of the UltraVueP, UltraVue/C (hioxifilcon B) Soft (Multifocal) Daily Wear Contact Lens (Clear & Blue Visibility Tim, Lathe-cut from Lens Blank), are substantially equivalent to the predicate devices. In addition, the water content, polymer, DK value, refractive index, specific gravity, and light transmission are as well substantially equivalent to the 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.
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.
