## Description of Device:
The LenSx Laser System is an ophthalmic surgical laser which uses focused femtosecond laser pulses to create incisions and to separate tissue within the lens capsule, crystalline lens, and the cornea. A femtosecond light pulses is focused into a sufficiently small spot in order to achieve photodisruption of the tissue inside the focus. A tiny volume of tissue, a few microns in diameter, is thereby photodisrupted at the laser focus. A computer-controlled scanning system directs the focused laser beam throughout a threedimensional pattern to produce an incision. The surgical effect is produced by scanning thousands of individual pulses per second to produce a continuous incision or tissue separation.
The laser pulses are delivered through a Patient Interface accessory that is placed on the surface of the cornea and fixes the position of the eye with respect to the delivery system. Two models of the Patient Interface accessory are offered for use with the LenSx Laser System: the LenSx Laser Patient Interface and the LenSx SoftFit Patient Interface. Both models consist of a sterile, disposable applanating lens and suction ring assembly that contacts the cornea and fixes the eye with respect to the delivery system. In addition, LenSx SoftFit Patient Interface model comes with a soft contact lens that is positioned against the internal surface of the patient Interface glass. For cataract procedures, the LenSx SoftFit Patient Interface is used. For corneal flap procedures, the LenSx Laser Patient Interface is used.
## Indications for Use:
The LenSx Laser System is indicated for use:
- · In the creation of corneal cuts/incisions (single-plane, multi-plane and arcuate), anterior capsulotomy and laser phacofragmentation during cataract surgery. Each of these procedures may be performed either individually or consecutively during the same surgery.
{5}------------------------------------------------
- · In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea
#### Description of Safety and Substantial Equivalence:
The subject of this Traditional 510(k) premarket notification is the software and hardware modifications to the LenSx Laser System and the removal of the indication for lamellar keratoplasty from the Indications for Use statement. All modifications were tested to show substantial equivalence to the predicate devices and do not alter the safety and effectiveness of the devices.
The LenSx Laser System is essentially the same device as the predicate LenSx Laser System. These modifications are categorized as follows:
- Hardware updates to improve manufacturability and serviceability. Hardware ● modifications to implement switchable laser operation at 50 or 150 kHz.
- . Software updates to implement the use of a planner Ethernet device for cataract surgery, re-enabling flap functionality that was previously cleared, and introducing an optional lens fragmentation pattern whose parameters are within previously cleared treatment ranges.
- Labeling updates to the operator's manual to reflect the implementation of the ● changes described above.
- . A revised Indications for Use statement that removes the indication for lamellar keratoplasty.
- . Extension of shelf-life to two (2) years for the sterile disposable LenSx Laser SoftFit Patient Interface.
All modifications were tested to show substantial equivalence to the predicate devices and do not alter the safety and effectiveness of the devices. Table A summaries the substantial equivalence between the modified device and the predicate devices.

## Table A: Substantial Equivalence Comparison
## Performance Data
The performance data supporting substantial equivalence of the LenSx Laser with the above modifications include:
- . Evaluation of the accuracy and reproducibility of the depths and geometry of each of the previously cleared treatment patterns using the modified LenSx Laser in comparison to acceptance criteria established for the predicate LenSx Laser.
{7}------------------------------------------------
- Evaluation of the accuracy and reproducibility of energy stability using the . modified LenSx Laser in comparison to acceptance criteria established for the predicate LenSx Laser.
#### Non-clinical Testing:
Successful verifications and process validations were performed on the modified device demonstrating equivalence to the predicate devices for the creation of corneal flaps, and for the creation of phacofragmentation patterns including lens fragmentation, capsulotomy treatments and corneal incision/cuts. Additionally, successful verification was performed on the modified device to verify the accuracy and reproducibility of laser energy at laser repetition rates of 150 kHz and 50 kHz. Finally, all hardware modifications were verified to demonstrate equivalence to the predicated device.
Non-clinical performance testing demonstrated that:
- . The modified LenSx Laser delivers a high degree of accuracy and reproducibility for the creation of corneal flaps suitable for LASIK compared to the predicate devices.
- The modified LenSx Laser delivers a high degree of accuracy and reproducibility ● for the creation of phacofragmentation patterns, including lens fragmentation treatments, capsulotomy treatments and corneal incisions/cuts.
- The modified LenSx Laser delivers a high degree of accuracy and reproducibility in the generation of laser pulse energies up to 2.6 uJ (for 150 kHz) and 15 uJ (for 50 kHz).
- Hardware modifications were verified to demonstrate equivalence of the ● modified device to the predicate devices. All hardware modifications met required verification criteria.
#### Clinical Testing:
The scope of the software and hardware modification did not require clinical testing to establish safety and effectiveness of the modified device.
#### Conclusions
The subject of this Traditional 510(k) premarket notification is the hardware and software modifications to the LenSx Laser System, the extension of shelf life for the LenSx Laser SoftFit Patient Interface, the removal of the indication for lamellar keratoplasty from the Indications for Use statement, and labeling changes to support
{8}------------------------------------------------
these modifications. All hardware and software modifications to the LenSx Laser System were tested to show substantial equivalence to the predicate devices and do not alter the safety and effectiveness of the devices.
With the exception of the removal from the indication for use for the creation of a cut/resection for lamellar keratoplasty, the modified device in this 510(k) is substantially equivalent to the predicate devices.

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.
