The OPHTHALMIC YAG LASER SYSTEM YC-200 consists of a slit lamp and the YAG Laser and is indicated for the performance of posterior capsulotomy, posterior membranectomy, pupillary membranectomy, iridotomy (hole in the iris) and selective laser trabeculoplasty.
Device Story
The YC-200 is an ophthalmic pulsed laser system using a 1,064 nm Nd:YAG laser for photodisruption and an optional 532 nm laser for selective laser trabeculoplasty (SLT). The system integrates a slit lamp, laser source, control box, and headrest. Operators (ophthalmologists) use the slit lamp to visualize the eye, align the aiming beams, and trigger laser emission via hand or foot switch. In YAG mode, it performs capsulotomy and iridotomy; in SLT mode, it performs trabeculoplasty. A combination delivery unit allows connection to the GYC-500 green laser for photocoagulation, though YAG/SLT functions are disabled when this unit is active. The device assists in surgical precision through focus-shift functions and SLT-NAVI software, which tracks treatment progress. By enabling precise ocular tissue disruption or photocoagulation, the device facilitates various ophthalmic surgeries, potentially improving patient visual outcomes.

## INDICATIONS FOR USE
The OPHTHALMIC YAG LASER SYSTEM YC-200 consists of a slit lamp and the YAG Laser and is indicated for the performance of posterior capsulotomy, posterior membranectomy, pupillary membranectomy, iridotomy (hole in the iris) and selective laser trabeculoplasty.
## PRODUCT DESCRIPTION
The OPHTHALMIC YAG LASER SYSTEM YC-200 is an ophthalmic pulsed laser system using a 1,064 nm Q-switched pulsed Nd: YAG laser as the treatment beam source. The system consists of two types, differing only in the available types of laser emission. The two types are collectively referred to as "YC-200" throughout this 510(k). The operation mode(s) available differs depending on the type.
| Type name | Model name | Emitted laser (wavelength) | Operation mode available |
|------------------|------------|------------------------------------------------|--------------------------|
| YC-200 | YC-200 | Nd: YAG laser (1,064 nm) | YAG mode |
| YC-200 S<br>Plus | YC-200 | Nd: YAG laser (1,064 nm)<br>SLT laser (532 nm) | YAG mode<br>SLT mode |
As shown in the above table, the YC-200 S Plus provides the operator with two treatment modes, YAG mode and SLT mode, whereas the YC-200 type provides the operator with a single treatment mode, YAG mode.
In YAG mode, treatment using the YAG treatment beam whose wavelength is 1,064 nm is available. This mode is used mainly for posterior capsulotomy and iridotomy. The 360-degree rotating two-aiming-beam system that separates the YAG aiming beam into two beams is

{6}------------------------------------------------
used. The focus position is determined according to the alignment of the beams. In YAG mode, single irradiation mode and burst mode are available. In single mode, one shot of the treatment beam is emitted each time the trigger switch is pressed, whereas in burst mode, two or three shots of the treatment beam are emitted each time the trigger switch is pressed. In YAG mode, the focus shift function to shift the focal points of the YAG treatment beam on the basis of the YAG aiming beam is available. This function allows the operator to shift the focal point of the YAG beam to the posterior chamber side compared to the aiming beam in order to prevent pitting of the intraocular lens.
In SLT mode, treatment using the YAG treatment beam whose wavelength is 532 mm is available. This mode is used for selective laser trabeculoplasty. In this mode, a parfocal optical system is used. In the parfocal optical system, the image of an object surface is formed on the target surface. The SLT aiming beam is emitted from the fiber tip (the object surface) so that it appears as a sharply-edged spot on the target surface. The focus position is determined according to the projection status of the beams. In SLT mode, SLT-NAVI assists the operator in surgery by specifying the laser emission positions and sequence before the treatment is available. The progress status of laser treatment is intuitively displayed in real time in the SLT-NAVI area of the main screen based on the premise that the treatment is proceeding as scheduled.
The system is mainly comprised of the YC-200 main body that incorporates a laser source, and a slit lamp that is similar to the previously cleared SL-2000 (K163564), a head rest, a control box that controls laser emission, and a connector box.
To use the YC-200, the operator should first adjust the focus of the evepieces to the operator's refractive error and adjusts the evepieces to the operator's pupillary distance. The operator instructs the patient to place his or her chin on the chinrest, to rest his or her forehead on the forehead rest, and to hold the grips. The operator aligns the level of the patient's eye with the eye level marker, fasten the patient's head with the head belt, and instructs the patient to look at the fixation lamp to stabilize his or her visual axis. The operator looks through the microscope to observe the treatment site. The operator sets laser emission conditions such as laser power output through the control box of the YC-200, turns on the aiming beam, and set the YC-200 to the READY mode. Alignment is achieved when the operator adjusts the joystick

and contact lens to align the aiming beam focus with the target position. Finally, the operator presses the hand switch or depresses the optional foot switch to emit the treatment beam in the READY mode while observing the operative field with the slit lamp.
One of the reasons for this 510(k) submission is to add the combination delivery unit to connect the subject device to the GYC-500 previously cleared in 510(k) No. K152603.
The combination delivery unit allows the operator to perform photocoagulation using the green laser beam (532 nm) or photodisruption using the Nd: YAG laser pulse beam (1064 nm, hereafter referred to as "YAG laser beam") or SLT laser (532 nm, for YC-200 S plus only) while observing the patient's eve with the slit lamp of the YC-200. The delivery unit is connectable to the previously cleared Green Laser Photocoagulator GYC-500, and the subject YC-200. The photocoagulation unit of the combination delivery unit is mounted on the subiect YC-200's slit lamp and is connected to the GYC-500 main body using a connecting cable and a fiber-optic cable.
The operator selects the laser beam to be emitted by switching the optical path using the laser beam selector of the combination delivery unit. The optical path of the combination delivery unit for the green laser beam is completely independent from that of the subject YC-200 for the Nd: YAG laser beam. When "YC" is selected by the laser beam selector to select the laser beam to be emitted, the laser refractive mirror is stored in the photocoagulation unit of the delivery unit. When "COAG" is selected by the laser beam selector, the laser refractive mirror comes out from the photocoagulation unit.
When the combination delivery unit is attached to the YC-200 and connected to the previously cleared GYC-500 (510(k) No. K152603), the YC-200 works strictly as a diagnostic slit lamp - all photodisruptor and SLT laser functions are disabled.
The combination delivery unit is comprised of the photocoagulation unit, and protective filter. The photocoagulation unit adjusts the spot size of the treatment beam and aiming beam emitted from the GYC-500, while the protective filter protects the operator's eve from the reflected green laser beam that can be emitted only when the protective filter is inserted in the optical path.

YC-200 510(k) 4 of 6
{8}------------------------------------------------
The green laser beam from the GYC-500 requires a delivery unit to be delivered to the patient's eye. The green laser beam is delivered to the patient's eve via the combination delivery unit when it is mounted on the YC-200. The combination delivery unit is intended to save the area occupied by the slit lamp of delivery unit for the GYC-500 by using the slit lamp of the YC-200 consistently during both photocoagulation and photodisruption.
Another reason for this 510(k) submission is to add "posterior membranectomy" is to expand treatment options. With the addition of "posterior membranectomy" to the indications for use, the split mirror illumination tower for posterior membranectomy is added as an optional accessory. The split mirror illumination tower was designed to irradiate the target with slit illumination so that the slit illumination is made incident from the center while allowing the YAG treatment beam to pass between the upper and lower mirrors. The previously cleared illumination tower equipped with a tilting function for SLT mode, and illumination tower with the base fixed for YAG mode do not allow the treatment beam to be delivered to the posterior segment of the eye while the operator observes the posterior segment because these illumination towers themselves interrupt the YAG treatment beam. Thus, the previously cleared ones are inappropriate for posterior membranectomy.
#### SUBSTANTIAL EQUIVALENCE
The YC-200 is equivalent to the predicate devices, NIDEK OPHTHALMIC YAG LASER SYSTEM YC-200, and Ellex Medical Ptv. Ltd. LUMENIS SELECTA DUET. The YC-200, and the predicate devices are Nd:YAG photodisruptor laser and Selective Laser Trabeculoplasty (hereafter referred to as "SLT") laser intended for use in ophthalmic surgical procedures, including posterior capsulotomy, iridotomy, and selective laser trabeculoplasty in the same anatomical sites.
The YC-200 is substantially equivalent to the primary predicate device in principles of operation, technological characteristics, and performance. Any differences in technological characteristics among the subject device, and primary predicate device do not raise any new issues of safety or effectiveness. Thus, the YC-200 is substantially equivalent to the primary predicate device.
## TESTING IN SUPPORT OF A SUBSTANTIAL EQUIVALENCE DETERMINATION
NIDEK CO., LTD.
{9}------------------------------------------------
All necessary bench testing was conducted on the OPHTHALMIC YAG LASER SYSTEM YC-200 to support a determination of substantial equivalence to the predicate and reference devices. The tests performed include:
- Ophthalmic Testing per ISO15004-1
- Testing for Protection against Light Hazard per Z80.36 and ISO15004-2
- Slit Lamp Testing per ANSI Z80.37
- Laser Product Safety Testing per IEC 60601-2-22 and IEC 60825-1
- Usability Testing per IEC 62366-1
- Electrical Safety Testing per ANSI AAMI ES60601-1 and Electromagnetic Compatibility Testing per IEC60601-1-2.
- Risk management per ISO14971
The collective performance testing demonstrates that the YC-200 does not raise any new questions of safety or effectiveness when compared to the primary predicate device. The results of the performance testing demonstrate that the YC-200 performs as intended and does not raise any new questions of safety or effectiveness.

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.
