Intended Use

The LensAR Laser System is indicated for anterior capsulotomy and laser phaco fragmentation during cataract surgery. The anterior capsulotomy and laser phaco fragmentation procedures may be performed either individually or consecutively during the same surgery.

Device Description

The LensAR Laser System is an ophthalmic surgical laser that has already been cleared for use in anterior capsulotomy in cataract surgery (K090633). It is now intended for additional use in anterior capsulotomy and laser phacofragmentation in cataract surgery, performed individually or consecutively during the same surgery.

The LensAR Laser generates ultrashort laser pulses that are scanned in a three-dimensional pattern in the eye to cut the anterior capsulotomy and to pre-cut the lens into small pieces for easy removal by conventional ultrasound phaco fragmentation. The fragmentation pattern is customized to the patient's eye based on precise measurement of the size, shape and position of the patient's lens by a built-in optical measuring system. During the measurement and subsequent application of the laser pulses, the eye is positioned and immobilized by an off-the-shelf suction ring assembly which is affixed to the eye and which is in turn docked to a refractive index matching eye docking (IMED) device mounted to the laser system.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the LensAR Laser System, based on the provided text:

No acceptance criteria or reported device performance metrics (e.g., success rates, accuracy percentages, safety endpoints with specific thresholds) are explicitly stated in the provided text. The document focuses on demonstrating substantial equivalence to predicate devices through a clinical study rather than defining specific performance thresholds for acceptance.

However, it describes the clinical study that provided performance data to support the device's substantial equivalence.


Study that Proves the Device Meets the Acceptance Criteria (Implicitly, for Substantial Equivalence):

1. A table of acceptance criteria and the reported device performance

As mentioned above, no explicit quantitative acceptance criteria or reported device performance metrics are provided in the document. The study aimed to demonstrate the device's clinical performance in comparison to predicate devices, inferring safety and effectiveness for substantial equivalence.

2. Sample size used for the test set and the data provenance

  • Sample Size (Test Set): 88 subjects (for the primary cohort, one eye per subject) and a control cohort of contralateral eyes in these subjects.
  • Data Provenance: Prospective clinical study performed outside the U.S.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This information is not provided in the document. The study describes the procedures performed (laser fragmentation/capsulotomy followed by phacoemulsification if needed) and a control group receiving conventional methods. It does not detail who established a "ground truth" or what that ground truth would specifically measure beyond the procedural outcomes themselves (e.g., successful fragmentation, clear capsulotomy).

4. Adjudication method for the test set

This information is not provided in the document.

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

  • MRMC Study: No, this was not an MRMC study related to human reader performance with AI. The device is a surgical laser system, not an AI-assisted diagnostic or interpretation tool.
  • Effect Size: N/A, as it's not an MRMC study with AI assistance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The device itself is a standalone surgical laser system (an "algorithm" in the sense of its operational program). It performs the laser treatment. The clinical study evaluated the overall surgical procedure where the laser performs its function, followed by human intervention (phacoemulsification if needed). It's not a diagnostic algorithm that assists a human reader.

7. The type of ground truth used

The clinical study evaluated the clinical performance of the surgical procedures using the LensAR Laser System. The "ground truth" implicitly refers to the successful completion and clinical outcomes of anterior capsulotomy and laser phacofragmentation during cataract surgery, as observed by ophthalmologists. The document mentions:

  • "Summary of Pre-Clinical Testing": "accuracy and reproducibility of capsulotomy and laser phaco fragmentation incisions in porcine eyes and plastic substrates."
  • "Summary of Clinical Studies": describes patients undergoing procedures and follow-up.
    The criteria for "success" or "performance" are not explicitly defined as a specific "ground truth" metric but rather related to the procedural outcomes and comparative performance against conventional methods.

8. The sample size for the training set

This information is not provided in the document. The document describes pre-clinical testing and a clinical study but does not detail a "training set" in the context of machine learning or AI, as this is a surgical device.

9. How the ground truth for the training set was established

N/A, as no "training set" in the AI/ML sense is mentioned or relevant for this type of medical device's submission summary. The product development likely involved extensive engineering and testing against design specifications, but this is not framed as a "training set" with ground truth in this context.

DEVICE DESCRIPTION

  • 1

The LensAR Laser System is an ophthalmic surgical laser that has already been cleared for use in anterior capsulotomy in cataract surgery (K090633). It is now intended for additional use in anterior capsulotomy and laser phacofragmentation in cataract surgery, performed individually or consecutively during the same surgery.

The LensAR Laser generates ultrashort laser pulses that are scanned in a three-dimensional pattern in the eye to cut the anterior capsulotomy and to pre-cut the lens into small pieces for easy removal by conventional ultrasound phaco fragmentation. The fragmentation pattern is customized to the patient's eye based on precise measurement of the size, shape and position of the patient's lens by a built-in optical measuring system. During the measurement and subsequent application of the laser pulses, the eye is positioned and immobilized by an off-the-shelf suction ring assembly which is affixed to the eye and which is in turn docked to a refractive index matching eye docking (IMED) device mounted to the laser system.

STATEMENT OF INTENDED USE

The LensAR Laser System is indicated for anterior capsulotomy and laser phaco fragmentation during cataract surgery. The anterior capsulotomy and laser phaco fragmentation procedures may be performed either individually or consecutively during the same surgery.

TECHNOLOGICAL CHARACTERISTICS COMPARISON

The LensAR Laser System proposed for use in phacofragmentation is identical with respect to all technological characteristics to the previously cleared LensAR for use in anterior capsulotomy (K090633). Substantial equivalence is also drawn to previously cleared phacofragmentation systems.

As described in K090633, anterior capsulotomy is performed by delivering a cylindrical pattern of laser pulses to intersect the anterior lens capsule. In the laser phaco fragmentation procedure, the lens is divided into a number of radial sections, similar in shape to those created by the conventional manual "phaco chop" technique (Chop), and then further divided by applying a set of concentric cylindrical cuts through the radial sections (Cylinder).

Following the laser procedure and entry into the eye by conventional means, the fragmented nuclear sections created by the LensAR Laser are further fragmented by ultrasound if necessary, and removed using a standard phacoemulsification probe and aspiration.

Predicate devices include laser and ultrasound phacoemulsification devices cleared for phacofragmentation, such as the Alcon Series Infiniti System (Alcon Laboratories, Inc., K021566 and K082845) and the LenSx Laser 550 (K082947 and K094052). Ultrasound phacofragmentation devices utilize a piezoelectric ultrasonic source that generates similar acoustic and cavitation effects that, along with mechanical effects from the probe, result in

{2}------------------------------------------------

phacofragmentation. The LenSx Laser works in the same technical manner as that described above for the LensAR device.

The LensAR Laser's ultrashort, photo disruptive pulses are of sufficiently low energy that the system can accomplish phaco fragmentation while transmitting to surrounding tissue only a tiny fraction of the ultrasonic shockwaves/energy generated by handheld ultrasound phaco fragmentation probes. The laser treatment is applied directly to the crystalline lens through the cornea without the necessity of creating an external wound.

BRIEF SUMMARY OF PRECLINICAL AND CLINICAL PERFORMANCE TEST RESULTS

The performance data supporting substantial equivalence of the LensAR Laser system to the predicate devices are summarized as follows:

Summary of Pre-Clinical Testing

Testing and analyses performed included accuracy and reproducibility of capsulotomy and laser phaco fragmentation incisions in porcine eyes and plastic substrates. The data demonstrated that the LensAR produces anterior capsulotomies and laser phaco fragmentation incision patterns that are accurate and predictable in size and shape. Additional safety testing comparing the acoustic and thermal characteristics of the device to predicate ultrasound phaco emulsification devices demonstrated a safe operating profile with respect to these parameters. Evaluation on ex vivo porcine eyes confirmed the safety with respect to corneal endothelium.

Summary of Clinical Studies

A prospective clinical study was performed outside the U.S. to evaluate clinical performance. A total of 88 subjects were treated with either a laser anterior capsulotomy/laser lens fragmentation, or a laser fragmentation/manual continuous curvilinear capsulorhexis (CCC), followed if needed by further standard ultrasound lens fragmentation and then irrigation aspiration of the lens in one eye. The eye selection in each patient was the one having the worse cataract condition. In patients needing bilateral cataract removal, the contralateral (fellow eye) of the patient was treated with conventional CCC and ultrasound phacofragmentation at some point after the first eye surgery.

The Primary cohort underwent initial laser phacofragmentation or laser anterior capsulotomy and phacofragmentation using the LensAR Laser, followed if needed by phacoemulsification using ultrasound with the Alcon Series Infiniti System.

A Control Cohort of contralateral eyes in these subjects underwent CCC/phacofragmentation and phacoemulsification with the Alcon Infiniti (predicate device), using a torsional mode, a method demonstrated in the literature to significantly reduce ultrasound power requirements as compared to earlier ultrasound longitudinal devices.
