The Nidek DC-3300 Laser Diode Photocoagulator is indicated for all retinal photocoagulation procedures, such as limited and pan-retinal, transpupillary laser photocoagulation, endophotocoagulation and transscleral photocoagulation, and glaucoma procedures, such as laser trabeculoplasty and iridotomy. The DC-3300 is used in combination with various delivery systems, such as slit lamps, binocular indirect ophthalmoscopes, endoprobes, and transscleral probes.
The DC-3300 Laser Diode Photocoagulator is an 808 nm continuous wave device. The DC-3300 consists of a compact, lightweight main console, footswitch and carrying case. The aiming laser of the DC-3300 is a red diode with a wavelength of 633 nm. A number of delivery systems are available with the DC-3300. A Slit Lamp Delivery Unit (Nidek SL-1600) Multipurpose Delivery Unit for the attachment of slit lamps (Nidek SL-1600), Endophotocoagulation Set, Binocular Indirect Ophthalmoscope (Models A and B), and Transscleral Photocoagulation probes.
The Nidek DC-3300 Laser Diode Photocoagulator is a device for ophthalmic photocoagulation procedures.

2. Sample size used for the test set and the data provenance
The provided text does not specify a sample size for a test set in the context of clinical performance data for patients. The performance data described relates to compliance with safety standards and functional specifications of the device itself.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable. The study is based on engineering and safety standard compliance, not clinical ground truth established by experts.
4. Adjudication method for the test set
Not applicable. There is no clinical test set requiring adjudication in the provided information.
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 medical device for laser photocoagulation, not an AI-assisted diagnostic or imaging device requiring human reader assessment.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Not applicable. This is a standalone medical laser device, and its performance is evaluated in terms of its technical specifications and compliance with safety standards, not as an algorithm.
7. The type of ground truth used
The "ground truth" for this device's performance is its conformance to established international and national safety standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-1-4, IEC 60601-2-22, IEC 60825-1, UL 2601-1) and its adherence to product specifications and risk analysis findings.
8. The sample size for the training set
Not applicable. This device is not an AI/ML model for which a training set would be required.
9. How the ground truth for the training set was established
Not applicable, as there is no training set for this type of device.
