#### DEVICE DESCRIPTION 4.4
The LenSx Laser System uses focused femtosecond laser pulses to create incisions and separate tissue in the lens capsule, crystalline lens, and the cornea. Individual photodisruption locations are controlled by repeatedly repositioning the laser focus. The light pulse 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. The surgical effect is produced by scanning thousands of individual pulses per second to produce a continuous incision or tissue separation.
The location of the tissue photodisruption is controlled by moving the focus of the laser beam to the desired surgical target location. A computer-controlled scanning system directs the laser beam throughout a three-dimensional pattern to produce an incision. The laser pulses are delivered through a Patient Interface accessory that is placed on the surface of the cornea and fixes the eye with respect to the delivery system.
This 510(k) premarket notification is being submitted to seek clearance for an additional patient interface accessory to be offered for use with cataract procedures in addition to the original patient interface accessory to the LenSx Laser System (cleared under K120732 for cataract and lamellar resection procedures). The SoftFit Patient Interface differs from the original Patient Interface (K120732) in that it has an extended suction ring skirt that enables positioning of a soft contact lens against the internal surface of the patient interface glass. The soft contact lens is similar to a standard daily wear contact lens indicated for the correction of ammetropia, with a slightly modified edge to enable fitting into the SoftFit Patient Interface. The materials and manufacturing processes used for the soft contact lens component of the proposed SoftFit Patient Interface accessory are identical to the processes used for the predicate daily wear soft contact lens (K100244).
With the soft contact lens insert in place, the SoftFit Patient Interface is then mounted onto the LenSx laser system for docking onto the eye in a manner that is identical to the original LenSx Laser Patient Interface. As a result, use of the soft contact lens substantially reduces intraocular pressure (IOP) during the laser procedure, enhancing comfort and addressing potential concerns in patients with a history of glaucoma.
For cataract procedures, either a LenSx Laser Patient Interface or a SoftFit Patient Interface may be used. The original LenSx Laser Patient Interface is used for keratoplasty and corneal flaps.
{2}------------------------------------------------
# INDICATION FOR USE 4.5
The following indications for use for the LenSx Laser System are unchanged from the previously cleared device (K120732):
- · In the creation of corneal cuts/incisions, anterior capsulotomy and laser phacofragmentation during cataract surgery. Each of these procedures may be performed either individually or consecutively during the same surgery.
- · In the creation of a lamellar cut/resection for lamellar keratoplasty, and in the creation of a penetrating cut/incision for penetrating keratoplasty
- · In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea
# TECHNOLOGICAL CHARACTERISTICS COMPARISON 4.6
The LenSx Laser is unchanged and this 510(k) is intended to introduce an alternative Patient Interface accessory (the SoftFit Patient Interface) for use with cataract surgery procedures. The original Patient Interface (cleared under K120732) will continue to be available for use with cataract, keratoplasty and corneal flap procedures.
The SoftFit Patient Interface consists of a slightly modified Patient Interface and a daily wear soft contact lens insert. The SoftFit PI has an extended suction ring skirt that enables positioning of the contact lens against the internal surface of the patient interface glass. The soft contact lens is identical to standard daily wear contact lens indicated for the correction of ammetropia (K100244), with a slightly modified edge to enable fitting into the SoftFit Patient Interface. The outer curvature of the soft contact lens matches the internal curvature of the patient interface glass. The inner curvature of the soft contact lens approximates the average corneal curvature. With the soft contact lens in place, the SoftFit Patient Interface is then mounted onto the LenSx Laser system for docking onto the eye in a manner that is identical to the original Patient Interface. The SoftFit Patient Interface results in a significantly lower intraocular pressure elevation during the laser procedure than the original Patient Interface.
#### BRIEF SUMMARY OF PERFORMANCE TEST RESULTS 4.7
The performance data supporting substantial equivalence of the SoftFit Patient Interface accessory include:
- Evaluation of the holding force and average intraocular pressure increase . generated by original and SoftFit Patient Interfaces.
- Evaluation of the accuracy and reproducibility of the depths and geometry of each . of the previously cleared cataract treatment patterns for the LenSx Laser when the SoftFit Patient Interface is used.

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.
