No
The summary describes automated features like Iris Registration and corneal marking, but it does not explicitly mention or provide evidence of AI or ML being used for these functions. The performance metrics relate to the accuracy of angle determination, which could be achieved through traditional image processing and algorithms.
Yes
The device is intended for use in patients undergoing cataract surgery for procedures like anterior capsulotomy, laser phacofragmentation, and creating corneal incisions, which are all therapeutic interventions for treating cataracts and preparing the eye for subsequent procedures.
No
The provided text indicates that the LENSAR Laser System - fs 3D is a surgical device used for therapeutic procedures (anterior capsulotomy, laser phacofragmentation, corneal incisions) during cataract surgery. While it integrates with pre-op analysis devices and uses topographer input for planning, its primary function is to perform treatment, not to diagnose a condition.
No
The device description explicitly states it utilizes a pulsed laser and includes integration with preop analysis devices, indicating it is a hardware-based system with software components, not a software-only device.
Based on the provided information, the LENSAR Laser System - fs 3D (LLS-fs 3D) is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Function: The LENSAR Laser System - fs 3D is a surgical laser system used directly on the patient's eye during cataract surgery. It performs procedures like capsulotomy, phacofragmentation, and corneal incisions.
- Lack of Sample Analysis: The device does not analyze samples taken from the body. Its function is to perform surgical actions on the eye itself.
Therefore, the LENSAR Laser System - fs 3D falls under the category of a surgical device, not an In Vitro Diagnostic device.

Device Description
The LENSAR Laser System - fs 3D (LLS-fs 3D) with Streamline™ is a medical device for use in ophthalmic surgery. The device utilizes a pulsed laser that can be used to cut a precision capsulotomy in the anterior lens capsule, to fragment the cataractous lens for removal during cataract surgery, and to create full and partial thickness single-plane and multi-plane arc cuts/ incisions in the cornea, each of which may be performed either individually or consecutively during the same procedure. Use of the laser provides automated precision control of the size of the capsular opening; the type and parameters of laser fragmentation treatment within the lens; as well as the size, architecture of incisions within the cornea, and depth of arcuate incisions. The LENSAR Laser System - fs 3D (LLS-fs 3D) with Streamline" includes the integration with preop analysis devices, automated Iris Registration with automatic cyclorotation adjustment, IntelliAxis" corneal marking for simple alignment of Toric IOLs as well as corneal treatment planning tools for precision guided laser treatments.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance Evaluation of the Iris Registration Feature: Verification and validation testing were completed to demonstrate that the device performance complies with the previously defined specifications and requirements identified for the predicate LENSAR Laser System. In addition to the verification of the three (3) new topographers, the Nidek OPD Scan Topographer data was re-run as part of the verification to demonstrate the Iris Registration results were substantially equivalent to its previous cleared specifications and requirements. All criteria were met and the results demonstrate that all performance specifications and requirements for the changes to the Iris Registration function and adding the Topcon Aladdin, OCULUS Pentacam® HR and Pentacam® AXL topographers as validated topographers for use with the Iris Registration feature of the LLS-fs 3D have been met.
The software on the proposed LLS-fs 3D System has been updated in support of the changes outlined above.

Summary of Clinical Studies
The addition of the Iris Registration changes and Topcon Aladdin, OCULUS Pentacam® HR and Pentacam® AXL topographers for use with the Iris Registration feature of the LENSAR Laser System does not change the indication for use. Thus, clinical performance data to demonstrate substantial equivalence was not required for this product change.
CONCLUSIONS 8.0
Based on the above supportive information, the proposed LENSAR Laser System - fs 3D (LLS-fs 3D) with the Iris Registration changes and the addition of the validated Topcon Aladdin, OCULUS Pentacam® HR and Pentacam® AXL topographers for use with the Iris Registration feature is substantially equivalent with respect to technological characteristics and indication for use as the legally marketed predicate device.
