No
The summary describes a laser indirect ophthalmoscope and its intended uses and technical specifications. There is no mention of AI or ML capabilities in the device description, intended use, or performance studies. The performance study focuses on simulated use and alignment, not algorithmic performance.
Yes.
The device is intended for soft and fibrous tissue incision, coagulation, vaporization, ablation, and vessel hemostasis, as well as retinal photocoagulation, laser trabeculoplasty, iridoplasty, and transscleral cyclophotocoagulation for various medical conditions, indicating its use in treating diseases or injuries.
No
The device is a treatment device, specifically a laser system for incision, coagulation, vaporization, ablation, and vessel hemostasis, as well as photocoagulation and other laser procedures in various medical specialties. While it involves "viewing" and "examination," these are for the purpose of guiding the laser treatment, not for diagnosing conditions.
No
The device description clearly states it is a "light combination and reflection viewing system" and a "portable alternative to patients who cannot be examined or treated with a fixed slit lamp adapter," indicating it is a hardware device with optical components. It also mentions being "worn on the physician's head."
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Iridex TruFocus LIO Premiere Laser Indirect Ophthalmoscope is a therapeutic and diagnostic imaging device used to directly view and treat tissues within the body (specifically the eye, ear, nose, and throat, and skin). It uses laser energy to perform procedures like photocoagulation, incision, and ablation.
- Lack of Specimen Analysis: The device does not analyze any biological specimens removed from the patient. It interacts directly with the patient's tissues.
Therefore, while it is a medical device used for diagnosis and treatment, it does not fit the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was conducted to validate the cumulative effect of device modifications and changes to the Operator Manual (the user instructions). A test procedure was developed to subject a sample size of 25 modified TruFocus LIO Premiere devices to a "simulated use" validation test following the modified Operator Manual. This test was designed to verify that when following the updated operator manual, the user could properly align and operate the device (e.g., the illumination and aiming/treatment beams would pass through the 20-diopter condensing lens and concentrically enter the simulated pupil plane using a pupil size of 6 mm in diameter, and achieve proper alignment of the internal illumination and aiming/treatment beam mirrors as well as illumination and aiming beam travel within the binocular field of view by using the adjustment control knobs). All units passed the simulated use test.

Description of Changes
The Operator Manual (Instructions For Use) has been updated in order to (a) provide additional illustrations and clarification of the various adjustment controls, (b) clarify the patient treatment instructions showing how to position the illumination and aiming beams within the binocular field of view and how to position the condenser lens along the axis of the aiming beam, and (c) establish a separate section to provide instructions for use of the binocular indirect ophthalmoscope (BIO) mode.
The submission also describes minor changes including a dimensional increase of a portion of the fiber optic cable assembly to improve attachment to molded clips at the top of the headband, an improved manufacturing process and new adhesive to enhance the bond reliability of the glass dust cover and cover frame used to shield the optics, and improvements to the aiming beam adjustment control cam surface finish resulting in a smoother actuation "feel" to the user.

Risk Analysis
A risk analysis was used to assess the impact of the cumulative effect of each device modification and the proposed modifications to the Operator Manual. The risk assessment methods comply with EN ISO 14971:2012 "Medical devices – Application of risk management to medical devices." The device and labeling changes described in this 510(k) submission were assessed for risk by reviewing the current Risk Management documentation for the TruFocus LIO Premiere device. The Hazard Analysis was reviewed and it was determined that no new hazards were introduced. The FMEA documents were reviewed to determine whether any risks were increased, reduced, or whether new risks were introduced as a result of the change (i.e., any difference in the occurrence or detectability of potential failure modes, or any new failure modes/potential causes). This assessment was performed by a qualified cross-functional team. The potential hazards were found to be sufficiently mitigated through the modified user instructions, device design, and change verification and validation to an acceptable level of risk. The potential benefits to patients outweigh the low residual risk of the modifications to the device and labeling.
Performance Data
In addition to verification and validation testing of the individual device changes, performance testing was conducted to validate the cumulative effect of device modifications and changes to the Operator Manual (the user instructions). A test procedure was developed to subject a sample size of 25 modified TruFocus LIO Premiere devices to a "simulated use" validation test following the modified Operator Manual. This test was designed to verify that when following the updated operator manual, the user could properly align and operate the device (e.g., the illumination and aiming/treatment beams would pass through the 20-diopter condensing lens and concentrically enter the simulated pupil plane using a pupil size of 6 mm in diameter, and achieve proper alignment of the internal illumination and aiming/treatment beam mirrors as well as illumination and aiming beam travel within the binocular field of view by using the adjustment control knobs). All units passed the simulated use test.
Conclusions
The modified TruFocus LIO Premiere device is as safe and effective as, and is substantially equivalent to, the predicate device.
