This document is a 510(k) Pre-market Notification for a medical device called SL3, a surgical laser system. It focuses on establishing substantial equivalence to previously cleared devices rather than primarily presenting a study to prove performance against acceptance criteria in the traditional sense of a clinical trial for diagnostic accuracy or treatment efficacy.
Therefore, many of the requested categories for a study proving device performance (like sample sizes for test sets, number of experts for ground truth, adjudication methods, MRMC studies, standalone performance, and training set details) are not applicable or not explicitly detailed in this type of regulatory submission.
The acceptance criteria here are implicitly related to the technical specifications and safety profile being substantially equivalent to the predicate devices. The "study" proving this is essentially the comparison table and the demonstration that the SL3 meets similar performance characteristics and safety standards as the predicate devices.
Here's the information parsed from the document based on your request, with explanations for what is not applicable to this type of submission:
1. A table of acceptance criteria and the reported device performance
For a 510(k) submission, "acceptance criteria" are not typically formal performance metrics in the way they would be for a diagnostic AI study. Instead, they are implicit in the substantial equivalence comparison - meaning the new device must perform comparably to the predicate devices and meet relevant safety and essential performance standards. The "reported device performance" is largely represented by its technical specifications.
Acceptance Criteria (Implied by Predicate Comparison) | Reported Device Performance (SL3) |
---|---|
Type of laser: Diode laser | Diode laser |
Wavelength: ~808 nm | $808 \pm 10$ nm |
Max output power: Comparable to predicates (2.0W - 2.5W) | 3.0 Watt |
Power requirements: Standard for medical devices | 100-240 VAC, @ 50-60 Hz, 1A |
Battery operation option: Comparable to predicate with battery | Corded or battery operation |
Operation mode: Continuous wave and pulsed | Continuous wave and pulsed |
Delivery system: 400 µm core quartz fiber | 400 µm core quartz fiber |
Fiber connection: FC connector to handpiece with disposable tip | FC connector to handpiece - Disposable tip magnetically attached to handpiece |
Aiming beam: 5 mW diode laser, 650 nm | 5 mW diode laser, 650 nm |
Activation means: Wireless foot switch | Wireless foot switch - takes 2 AA batteries |
Interface: Color LCD touch-screen GUI with pre-set procedures or manual control | Color LCD touch-screen GUI on desk unit displays 8 pre-set procedures or manual control to set power and laser mode (continuous or pulse) |
Diode Assembly: 2.0 - 2.5 watt single emitter diode | 3 watt single emitter diode lasing at 808 nm |
Cooling system: Heat sink or fan | Heat sink |
Laser diode power supply: External or internal | External |
Intended Use / Indications for Use: Same as predicates | Matches and potentially expands slightly (implicit in higher power) what is listed for predicates. All listed indications are covered. |
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not Applicable / Not Provided: This is a 510(k) pre-market notification for a laser device, not an AI or diagnostic device requiring a "test set" in the context of clinical performance data. The submission relies on technical comparisons and safety data, not a patient-level data set.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not Applicable: No "test set" or "ground truth" in this context as described for diagnostic or AI systems. The "ground truth" for a laser device would relate to engineering specifications, safety standards, and pre-clinical testing, which are performed by engineers and regulatory experts, not typically by medical experts establishing diagnostic ground truth from patient data.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not Applicable: No test set requiring annotation adjudication.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not Applicable: This is a surgical laser device; MRMC studies are used for diagnostic imaging systems, not for comparing human performance with and without a surgical instrument like a laser.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not Applicable: This device is a surgical instrument intended for human operation, not a standalone algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
- Type of Ground Truth: For this device, the "ground truth" is primarily based on engineering specifications, recognized national and international safety standards (e.g., laser safety standards), and the established performance and safety profiles of the predicate devices. Compliance with these technical and safety standards, along with successful pre-clinical testing (which would include electrical safety, EMC, laser emission measurements, etc.), forms the basis of "proof." There is no patient-level "ground truth" in the diagnostic sense.
8. The sample size for the training set
- Not Applicable: No "training set" as this is not an AI or machine learning device. Device development involves engineering design, prototyping, and testing, not data-driven training.
9. How the ground truth for the training set was established
- Not Applicable: No training set.

GILRAS SLIT LAMP, MODELS GR-SL7, GR-SL36, GR-SL54 AND GR-SL72
The GILRAS Slit Lamp is an AC-power slit lamp biomicroscope intended for use in eye examination of the anterior eye segment, from the cornea epithelium to the posterior capsule. It is used to aid in the diagnosis of diseases or trauma which affect the structural properties of the anterior eye segments.
The GILRAS Slit Lamp is an AC-power slit lamp biomicroscope intended for use in eye examination. There are 3 models GR-SL36, GR-SL54, and GR-SL72. These models differ only in the supplied accessories. All models have the same operating characteristics and intended use.
The provided document is a 510(k) premarket notification for the GILRAS Slit Lamp, which is a medical device. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than on providing performance data from a clinical study with acceptance criteria.
Therefore, the document does not contain the information requested regarding acceptance criteria and a study proving the device meets those criteria, as it relates to clinical performance metrics like sensitivity, specificity, etc.
Instead, the document demonstrates substantial equivalence through a technological comparison and compliance with recognized standards.
Here's a breakdown of what the document does provide in relation to your request, and why it doesn't fit the typical "acceptance criteria and study" format you've outlined:
1. A table of acceptance criteria and the reported device performance:
-
Acceptance Criteria: Not explicitly defined in terms of clinical performance (e.g., accuracy metrics). Instead, the "acceptance criteria" are implied by manufacturing specifications and compliance with recognized safety standards (ISO 10939:2007 and IEC 60601-1) and similarity of technological characteristics to the predicate device.
-
Reported Device Performance: The document provides a detailed comparison of theGILRAS Slit Lamp's technological characteristics against its predicate device, the 66 Vision-Tech YZ Slit Lamp. This comparison table effectively is the "performance" data in the context of this 510(k) submission, showing how the new device matches or is similar to the predicate.

- Not applicable. This is a hardware medical device, not an algorithm.
7. The type of ground truth used:
- For the purpose of this 510(k), the "ground truth" or benchmark is the legally marketed predicate device (66 Vision-Tech YZ Slit Lamp) and recognized industry standards (ISO 10939:2007 and IEC 60601-1). The entire submission hinges on demonstrating that the GILRAS Slit Lamp is "substantially equivalent" to this predicate and meets these standards.
8. The sample size for the training set:
- Not applicable. No training set for an algorithm is mentioned or relevant to this device submission.
9. How the ground truth for the training set was established:
- Not applicable. No training set.
Conclusion:
The K080776 document demonstrates the GILRAS Slit Lamp's "acceptance criteria" by showing its adherence to safety standards and its substantial equivalence in technological characteristics to a predicate device. It does not involve performance studies with clinical acceptance criteria, sample sizes, expert ground truth, or AI-related metrics as typically outlined in your request.
