#### INDICATIONS FOR USE
The Green Laser Photocoagulator GYC-500 is intended to be used in ophthalmic surgical procedures including retinal and macular photocoagulation, iridotomy and trabeculoplasty.
#### PRODUCT DESCRIPTION
The Green Laser Photocoagulator GYC-500 ("GYC-500") is a laser photocoagulator for ophthalmology using the 532 nm diode-pumped solid-state laser (green laser beam) as the treatment beam and 635 nm diode laser (red laser beam) as the aiming beam. Like other conventional laser photocoagulation system, the GYC-500 can be used in ophthalmic surgical procedures including retinal and macular photocoagulation, iridotomy and trabeculoplasty. The GYC-500 is a modified version of the GYC-1000 which was the subject of premarket notification number K 032085.
The GYC-500 is mainly comprised of the main body that incorporates a laser source, the control box that controls laser emission, and a delivery unit that guides the laser beam emitted from the main body to the patient's eye.
To use the GYC-500, the operator sets laser irradiation conditions such as laser output and laser application time according to the condition of treatment site through the control box of the GYC-500 or operation part of the connected delivery unit. When using a (attachable) slit lamp delivery unit, the operator observes the treatment site with the slit lamp, and aligns the treatment beam and aiming beam to the site. Then the operator presses the foot switch to
{5}------------------------------------------------
emit the treatment beam and aiming beam to the treatment site from the exit end of the GYC-500 system in a READY status while observing the operative field with the slit lamp. As the treatment beam is optically coaxial to the aiming beam, alignment is achieved when the user aligns the aiming beam to the treatment site. When the foot switch is pressed under the condition, the treatment beam of the set spot size is irradiated at which the aiming beam is projected. The operator can also select the laser irradiation pattern from a single laser spot and multiple laser spots in a predetermined pattern in a scanning manner.
Various types of the delivery units are available for the GYC-500. As the delivery units using a slit lamp, broadly speaking, two types of delivery units are available. One is called "Slit lamp delivery unit" integrating a slit lamp and a laser delivery unit. The other is called "Attachable delivery unit" that is the laser delivery unit integrating a protective filer and so on for connection to the slit lamp owned by the user. Either the slit lamp delivery units or attachable delivery units are divided into three types: 1) the unit only with the fixed protective filter that remains inserted into the optical path and without the micromanipulator (used for fine adjustment of the laser beam position), 2 ) the unit with the fixed protective filter or electrically-powered one (either filter is factory configured) and with the micromanipulator, and 3) the unit only with the electrically-powered protective filter, with the micromanipulator, and with the spot size control which is different from the aforementioned two types in mechanical structure.
Furthermore, the slit lamp delivery units are classified into "Slit lamp delivery unit" that delivers a single laser spot only, and "Scan slit lamp delivery unit" that delivers multiple laser spots in a predetermined pattern while scanning the laser spots as well as the single laser spot. In a similar manner, the attachable delivery units are further classified into "Attachable slit lamp delivery unit" that delivers a single laser spot only, and "Scan attachable slit lamp delivery unit" that delivers multiple laser spots in a predetermined pattern while scanning the laser spots as well as the single laser spot. The GYC-500 connected with a scan (attachable) delivery unit is called "Green Scan Laser Photocoagulator GYC-500 Vixi".
Various slit lamp delivery units are available that allow for the adaptation of the GYC-500 to a slit lamp. A fiber optic cable is connected from the GYC-500 main body to the slit lamp,
{6}------------------------------------------------
thereby allowing the laser beam to be sent to the delivery unit. With the delivery unit, the patient can be treated in a seated position. The following slit lamp types are available: Slit lamp delivery unit (NIDEK SL-1800 type), Scan slit lamp delivery unit (NIDEK SL-1800 type), Attachable delivery unit (NIDEK SL-1800/SL-1600 type, ZEISS SL 130 type, ZEISS 30 SL/M type, HAAG 900BM/900BQ type), and Scan attachable delivery unit (NIDEK SL-1800/SL-1600 type, ZEISS SL 130 type, ZEISS 30 SL/M type, HAAG 900 BQ type).
Other than the (scan and/or attachable) slit lamp delivery units, a binocular indirect ophthalmoscope (B.I.O.) delivery unit and a combination delivery unit are available.
The B.I.O. delivery unit allows the operator to perform photocoagulation while observing the fundus with a binocular indirect ophthalmoscope. With the delivery unit, the patient can be treated in a supine position. The B.I.O. delivery unit (Heine Omega 500 type and Keeler All Pupil II type) connects to the GYC-500 main body via a fiber optic cable. The B.I.O. delivery unit consists of a binocular indirect ophthalmoscope (with headband), a 20 D condensing lens illumination lamp, and stand. The headband fits over the operator's head and has height and circumference adjustment knobs. A working distance control sets the working distance, which can be varied within a range of 300 to 700 mm. The treatment and aiming laser spot size can also be selected by changing working distance (with the 20D condensing lens).
The combination delivery unit is mounted on the NIDEK Ophthalmic YAG Laser System YC-1800's slit lamp and is connected to the GYC-500 main body using a connecting cable and a fiber-optic cable. The delivery unit allows the operator to perform photocoagulation using the green laser beam (532 nm) or photodisruption using an Nd: YAG laser beam while performing observation of the eye with the slit lamp of the YC-1800. The optical path for the green laser beam is completely independent from that for the Nd: YAG laser pulse beam. The operator selects the laser beam to be emitted by switching the optical path using the laser beam selector of the delivery unit. This delivery unit is intended to save the area occupied by the slit lamp for the GYC-500 and that for the YC-1800 by using the slit lamp of the YC-1800 consistently for both photocoagulation and photodisruption.
The delivery units allow transpupillary photocoagulation using a slit lamp or binocular
{7}------------------------------------------------
indirect ophthalmoscope. The operator chooses the optimal delivery unit for the purpose of photocoagulation of the patient's eye.
### SUBSTANTIAL EQUIVALENCE
The GYC-500 is substantially equivalent to the predicate devices, Green Laser Photocoagulator Model GYC-1000, Multicolor Laser Photocoagulator System MC-500, and Multicolor Scan Laser Photocoagulator MC-500 Vixi. They are all laser photocoagulators that emit a laser-diode-pumped solid-state laser of 532 nm.
The GYC-500 is similar in technological characteristics, performance, principles of operation and has similar indications for use as the predicate devices. Any differences in technological characteristics between the proposed device and the predicate devices do not raise any new issues of safety or effectiveness. Thus, the GYC-500 is substantially equivalent to the predicate devices.
### TESTING IN SUPPORT OF SUBSTANTIAL EQUIVALENCE DETERMINATION
All necessary bench testing was conducted on the Green Laser Photocoagulator GYC-500 to support a determination of substantial equivalence to the predicate devices. The tests performed include:
- Ophthalmic Testing per ISO 15004-1, and ISO15004-2
- Slit Lamp Testing per ISO 10939
- Laser Product Safety Testing per IEC 60601-2-22 and IEC 60825-1
- Software Verification and Validation
- · Usability Testing per IEC60601-1-6 and IEC 62366
- · Electrical Safety Testing per IEC60601-1 and Electromagnetic Compatibility Testing per IEC60601-1-2.
The collective performance testing demonstrates that the GYC-500 does not raise any new questions of safety or effectiveness when compared to the predicate devices. The results of the performance testing demonstrate that the GYC-500 performs as intended and does not raise any new questions of safety or effectiveness.
{8}------------------------------------------------
## CONCLUSION
In summary, NIDEK CO., LTD. is of the opinion that the Green Laser Photocoagulator GYC-500 does not introduce any new potential safety risks, is as effective and performs as well as the predicate devices, and concludes that the GYC-500 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.
