#### DEVICE DESCRIPTION SUMMARY 6.3
The subject device is the AMO WHITESTAR SIGNATURE PRO Phacoemulsification System, which is an upgrade to the primary predicate device, the AMO WHITESTAR Signature Phacoemulsification System (K111697). Key device components included in this 510(k) submission are the system console, advanced linear (four-button) foot pedal (ALP), and wireless remote control. The system console and wireless remote control of the subject device are substantially equivalent to the console and wireless remote control of the primary predicate device in K111697. The Advanced Linear foot pedal (ALP) used with the subject device is substantially equivalent to the foot pedal used with the secondary predicate device, the COMPACT INTUITIV System, cleared under K133115.
The subject device is classified under 21 CFR 886.4670 as a "phacofragmentation system," described as an AC-powered device with a fragmenting needle intended for use in cataract surgery to disrupt a cataract with ultrasound and extract the cataract. Like the primary predicate device in K111697, the subject device is used to perform phacoemulsification by applying ultrasonic energy combined with the mechanical action of a vibrating phaco handpiece to the cataractous lens of the eye. The system performs four basic functions: phacofragmentation, irrigation of fluid, diathermy (bipolar), and vitrectomy. The functionality, performance, intended use, and fundamental scientific technology of the AMO WHITESTAR SIGNATURE PRO Phacoemulsification System and its accessories are equivalent to the AMO WHITESTAR Signature Phacoemulsification System cleared in K11169. The functionality, performance, intended use, and fundamental scientific technology of the Advanced Linear Foot Pedal (APL) used with the subject device is equivalent to the foot pedal used with the legally marketed COMPACT INTUITIV system, cleared in K133115.
The intended use of the subject device is anterior segment ophthalmic surgery (cataract). which is the same as the primary predicate device. The materials, energy source, operating mechanism, fundamental scientific technology, physical properties, duration and type of contact, and intended use of the subject device are identical to those of AMO WHITESTAR Signature Phacoemulsification System's console and remote control in K111697, and the COMPACT INTUITIV System's foot pedal in K133115 for the subject device's Advanced Linear foot pedal (APL). The FDA-recognized standards used for performance testing of the subject device are equivalent to those used for the primary predicate device in K111697.
#### 6.4 INDICATIONS FOR USE
The AMO WHITESTAR SIGNATURE PRO Phacoemulsification System is a modular ophthalmic microsurgical system that facilitates anterior segment (cataract) surgery. The modular design allows the users to configure the system to meet their surgical requirements.
#### TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE 6.5
The main technological characteristics of the AMO WHITESTAR SIGNATURE PRO Phacoemulsification System include phacoemulsification, diathermy, irrigation and aspiration, and vitrectomy. These technological characteristics are the same as those in the legally marketed device, the AMO WHITESTAR Signature Phacoemulsification System (K111697).
{6}------------------------------------------------
- A The Phacoemulsification mode is used to break up (emulsify) the nucleus of a lens, allowing it to be aspirated from the eye through a small incision.
- > The Diathermy (bipolar) mode is used to coagulate blood vessels during a surgical procedure and, in some cases, to coagulate the conjunctiva following a procedure.
- A The Irrigation/Aspiration mode allows for controlled aspiration of cortical material from the eve. while maintaining intraocular stability by replacing aspirated material with a balanced salt solution. A peristaltic pump provides a predictable and stable aspiration rate. Irrigation is gravity-fed, and intraocular pressure can be regulated by adjusting the height of the balanced salt solution bottle.
- > The Vitrectomy mode is used to cut and remove vitreous from the anterior segment of the eye during secondary intraocular lens implantation, following vitreous loss associated with trauma, or during primary cataract surgery.
These surgery modes are equivalent to the surgery modes of the primary predicate device, the AMO WHITESTAR Signature Phacoemulsification System.
Aside from the technological characteristics, the AMO WHITESTAR SIGNATURE PRO Phacoemulsification System is equivalent to its primary predicate device, the AMO WHITESTAR Signature Phacoemulsification System (K111697), and the Advanced Control Pedal (ALP) of the subject device is equivalent to the secondary predicate device, the foot pedal used in the COMPACT INTUITIV System (K133115), in terms of intended use, design, material, basic scientific concepts, energy source, manufacturing process, and FDArecognized standards used for performance testing. The intended use of the subject device is anterior segment ophthalmic surgery, which is the same intended use as the primary predicate device.
#### SUMMARY OF NON-CLINICAL TESTS 6.6
The AMO WHITESTAR SIGNATURE PRO Phacoemulsification System has undergone preliminary design verification and validation to address requirements, including electromechanical safety testing (IEC testing), and is in compliance with the applicable requirements of safety standards. The subject device passed the acceptance criteria and was found to perform as safely and effectively as the primary predicate device during the following modes of anterior segment ophthalmic surgery: phacoemulsification, irrigation/aspiration, diathermy, and vitrectory. Therefore, the subject device, including the console. ALP and wireless remote control. has similar safety, effectiveness, and performance profiles as the primary and secondary predicate devices in K111697 and K133115.
The AMO WHITESTAR SIGNATURE PRO Phacoemulsification System was developed and tested in accordance with AMO requirements and specifications, which comply with the following FDA-recognized consensus standards:

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.
