Intended Use

The VICTUS Femtosecond Laser Platform is indicated for use for:

  • the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea.
  • for anterior capsulotomy during cataract surgery.
Device Description

The VICTUS Femtosecond Laser Platform is a precision ophthalmic surgical laser indicated for use in the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea or for patients undergoing anterior capsulotomy during cataract surgery.

The VICTUS Femtosecond Laser Platform is an ophthalmic surgical femtosecond laser designed for cutting a precise corneal flap of pre-selected thickness and diameter. The system works by first being programmed with the depth and diameter at which the flap should be made. The surgeon then fixates the eye with a PMMA contact lens (referred to hereafter as the Patient Interface) that is connected to the laser via a vacuum tube. Flap thickness of 110 to 200 microns can be achieved in diameters of 6.0 to 9.5 mm.

In addition to the above, the VICTUS Femtosecond Laser Platform allows anterior capsular dissection which is achieved through precise individual micro-photodisruption of fissue, measuring a few microns in diameter, created by tightly focusing ultrashort laser pulses into the targeted capsular tissue. Pre-programmed patterns produce capsular resections of predetermined diameter and height. Capsular cut depth of 2245 to 5000 microns below the corneal surface can be achieved in diameters of 3 to 7 mm.

For both indications for use, laser pulses are delivered through a sterile disposable Patient Interface, consisting of a contact lens and suction clip to provide suction. The contact lens and suction clip assembly creates a reference surface for depth control and fix the eye relative to the delivery of the laser beam. Surgical effects are produced by scanning thousands of individual pulses, producing continuous incisions. The location of the tissue photodisruption is controlled by a fixed laser beam focused through a scanning optic system to the desired location.

AI/ML Overview

The provided text describes the VICTUS Femtosecond Laser Platform and its performance data. However, it does not explicitly state "acceptance criteria" in a table format with corresponding performance metrics for all aspects of the device. Instead, it presents an overall conclusion about the device's performance compared to predicate devices and manual methods.

Here's an analysis of the acceptance criteria and study information that can be extracted or inferred from the provided text, along with where the requested information is missing:

1. Table of Acceptance Criteria and Reported Device Performance

Feature/MetricAcceptance Criteria (Explicit or Inferred)Reported Device Performance
Anterior Capsulotomy: Reproducibility & Accuracy (Diameter, Depth, Height, Centration)Implied to be comparable to predicate devices and manual methods; "highly reproducible and accurate"Testing showed "highly reproducible and accurate capsular tissue diameter, depth, height, and centration."
Corneal Flap: Reproducibility & Accuracy (Diameter, Thickness, Centration)Implied to be comparable to predicate devices; "highly accurate"Flaps created were shown to result in "highly accurate tissue diameter, thickness, and centration."
Flap Thickness: Difference between achieved mean and intended mean≤ 10 µm(3.58 µm) (within acceptance criteria) with a standard deviation of approximately 6 µm
Anterior Capsulotomy: Comparability to standard manual procedure (Capsulorhexis/CCC)ComparableShown to be comparable to the standard manual procedure capsulorhexis (CCC).
Adverse Events / Severe Adverse EventsNot significantly different from manual procedureNot different between the two study groups up to 3-Month post-surgery.
Treatment SafetyGood, consistent with manual procedureGood, slit lamp examinations at one day and up to 3-Month post-surgery were consistent with manual procedure.
Post-Surgery Complications (Corneal edema, flare, trace anterior chamber cells)Comparable to manual groupComparable to those in the manual group.

Capsulotomy CompletenessSuccessfulConcluded that the VICTUS can be used successfully.
Capsulotomy CentrationSuccessfulConcluded that the VICTUS can be used successfully.
Applicability to various cataract gradesNo additional risksStudy population included cataract grades 1-5 and white/brown cataracts which did not pose any additional risks.

Missing Information/Cannot Be Determined from Text:

  • Explicit, quantifiably defined "acceptance criteria" for many of the qualitative performance descriptions (e.g., "highly accurate" or "good"). These are described as outcomes rather than pre-defined thresholds.

2. Sample Size Used for the Test Set and Data Provenance

  • Anterior Capsulotomy (Clinical Study):
    • Sample Size: 119 eyes of 118 subjects.
    • Data Provenance: Prospective, single-center, multi-surgeon clinical study. Country of origin is not explicitly stated, but the study was described as "clinical performance was evaluated in a clinical study...".
  • Flap Thickness (Clinical Data):
    • Sample Size: 18 eyes.
    • Data Provenance: Collected at a "VICTUS site located outside of the USA." This indicates retrospective perhaps, or a separate smaller clinical investigation.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • Anterior Capsulotomy (Clinical Study):
    • Ground Truth Establishment: "visual inspection during slit lamp examination" and "visual inspection at the day of surgery" were used to assess IOL centration, capsulotomy completeness, and centration. The study involved "multi-surgeon" participation.
    • Number of Experts/Qualifications: Not explicitly stated. The "multi-surgeon" aspect implies multiple surgeons were involved in both performing the procedures and potentially in the visual inspections, but their specific qualifications (e.g., years of experience, blinded assessment) are not detailed.
  • Flap Thickness (Clinical Data):
    • Ground Truth Establishment/Experts: Not explicitly stated how "achieved flap thickness" was measured or validated, nor who made those measurements or assessments.

4. Adjudication Method for the Test Set

  • Anterior Capsulotomy (Clinical Study): Not explicitly stated. The reliance on "visual inspection" by multiple surgeons might imply a consensus or individual assessment, but no formal adjudication method (like 2+1 or 3+1) is described.
  • Flap Thickness (Clinical Data): Not stated.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, What was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance?

  • Not applicable. This device is a femtosecond laser platform for surgical procedures, not an AI diagnostic or assistive device for human readers. The clinical study compares laser-assisted capsulotomy to manual capsulotomy, not human readers with and without AI.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done?

  • Partially applicable. The "Non-clinical performance data" section describes testing "without human-in-the-loop" in a surgical context, using inanimate materials (porcine eyes, agarose gel, PETG, PMMA) and scanning electronic microscopy to assess the laser's precision in creating capsulotomies and flaps. This demonstrates the device's inherent capability (akin to a standalone algorithm) to achieve specific physical outcomes.
  • However, the clinical studies do involve human surgeons operating the device (human-in-the-loop), albeit comparing the device's laser-assisted method to manual surgical techniques.

7. The Type of Ground Truth Used

  • Non-Clinical Data:
    • Direct Measurement/Visual Assessment: Scanning electronic microscopy for visual assessment of laser cuts, and measurements (mean values and 95% confidence intervals) against specified acceptance criteria using various inert materials.
  • Clinical Data (Anterior Capsulotomy):
    • Clinical Outcomes/Expert Visual Inspection: Comparison of adverse events, severe adverse events, post-surgical complications, IOL centration, and capsulotomy completeness/centration. The "ground truth" seems to be the collective clinical judgment and observation by surgeons and clinical staff via slit lamp examinations and visual inspection.
  • Clinical Data (Flap Thickness):
    • Direct Measurement (Implied): Comparison of "intended flap thickness" to "achieved flap thickness." The method for determining "achieved flap thickness" (which would be the ground truth here) is not detailed but would typically involve direct measurement techniques.

8. The Sample Size for the Training Set

  • Not applicable/Not explicitly mentioned in the context of device performance studies. This device is a surgical laser, not an AI or machine learning algorithm that requires a "training set" in the traditional sense. Its design and functional parameters are based on scientific principles and engineering, not data-driven machine learning models.

9. How the Ground Truth for the Training Set Was Established

  • Not applicable, as there is no mention of a "training set" for an AI/ML algorithm within the provided text. The device's fundamental scientific technology and algorithms for laser patterns "remain unchanged from those previously cleared" predicate systems, implying established and validated physical principles rather than learned models.

Description of the Device Subject to Premarket Notification:

The VICTUS Femtosecond Laser Platform is a precision ophthalmic surgical laser indicated for use in the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea or for patients undergoing anterior capsulotomy during cataract surgery.

The VICTUS Femtosecond Laser Platform is an ophthalmic surgical femtosecond laser designed for cutting a precise corneal flap of pre-selected thickness and diameter. The system works by first being programmed with the depth and diameter at which the flap should be made. The surgeon then fixates the eye with a PMMA contact lens (referred to hereafter as the Patient

Interface) that is connected to the laser via a vacuum tube. Flap thickness of 110 to 200 microns can be achieved in diameters of 6.0 to 9.5 mm.

In addition to the above, the VICTUS Femtosecond Laser Platform allows anterior capsular dissection which is achieved through precise individual micro-photodisruption of fissue, measuring a few microns in diameter, created by tightly focusing ultrashort laser pulses into the targeted capsular tissue. Pre-programmed patterns produce capsular resections of predetermined diameter and height. Capsular cut depth of 2245 to 5000 microns below the corneal surface can be achieved in diameters of 3 to 7 mm.

For both indications for use, laser pulses are delivered through a sterile disposable Patient Interface, consisting of a contact lens and suction clip to provide suction. The contact lens and suction clip assembly creates a reference surface for depth control and fix the eye relative to the delivery of the laser beam. Surgical effects are produced by scanning thousands of individual pulses, producing continuous incisions. The location of the tissue photodisruption is controlled by a fixed laser beam focused through a scanning optic system to the desired location.

The fundamental scientific technology remains the same as previously cleared for the FEMTEC Laser System under K0333354 and K110427. The indication for use for the VICTUS Femtosecond Laser Platform is a combination from those previously cleared under K033354 and K110427.

Indications for Use:

.

The VICTUS Femtosecond Laser Platform is indicated for use for:

  • the creation of a corneal flap in patients undergoing LASIK surgery or other treatment ● requiring initial lamellar resection of the cornea.
  • for anterior capsulotomy during cataract surgery. .

The VICTUS Femtosecond Laser Platform is capable of performing the above indications as previously cleared under the predicate systems discussed within this submission. The first part of the indication is for use in the creation of corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea. This indication for use remains unchanged from that previously cleared under K033354 (for FEMTEC Laser Microkeratome). The second part of the indication is for anterior capsulotomy during cataract surgery. This indication for use remains unchanged from that cleared under K110427 (FEMTEC Laser System for Capsulotomy). The combination of the two indications on one device does not pose any additional concern of safety or effectiveness.

Technical Characteristics Comparison:

The design principle of the VICTUS system is fundamentally the same as the predicate devices. Whereas the predicate devices beam steering and monitoring were provided by separate subassemblies (units), the VICTUS Femtosecond Laser Platform has integrated these subassemblies into one assembly also known as the ARGES Rail assembly. The ARGES Rail assembly is mounted in the application arm of the laser workstation. The main function is to receive the pulsed laser beam from the laser source, control the laser energy, steer the laser beam, and finally to focus the laser beam on to the cornea or lens of the patient's eye. For a treatment, this focus is guided along a well-defined three dimensional path that creates exact cuts in the tissue by laser induced optical breakdown (LIOB). Prior to start of the procedure, the ARGES Rail assembly receives the steering information (instruction list) via a digital interface from the graphical user interface personal computer (GUI-PC). The instruction list contains settings for the pulse energy as well as information on the desired position and speed of delivery. As compared to the predicate Femtec for Anterior Capsulotomy (K110427) which had an external OCT unit included, the VICTUS Femtosecond Laser Platform has an integrated OCT which is

Technolas Perfect Vision GmbH K120426

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

used for OCT guided anterior capsulotomy procedures.

The fundamental algorithms controlling the laser patterns to achieve either flap creation or anterior capsulotomy remain unchanged from those previously cleared in the predicate systems (K033354 and K110427). For flap creation the laser repetition rate has been increased from 12.5 kHz to 160 kHz which effectively shortens flap creation treatment time.

Performance Data:

The VICTUS Femtosecond Laser Platform has undergone testing and is in compliance with applicable safety standards as listed below.

StandardTitle
EN ISO 60601-1Medical electrical equipment – Part I: General requirements for safety
EN ISO 60601-1-2Medical electrical equipment – Part 1: General requirements for safety; 2.Collateral standard: electromagnetic compatibility; requirements andtests
EN ISO 60601-1-4Medical electrical equipment – Part 1-4: General requirements for safety;Collateral standard: Programmable electrical medical systems
EN ISO 60601-2-22Medical electrical equipment – Part 2: Particular requirements for thesafety of diagnostic and therapeutic laser equipment

The VICTUS Femtosecond Laser Platform has been found to perform equivalently to the predicate lasers for creation of a corneal flap in patients undergoing LASIK and for anterior capsulotomy during cataract surgery. Thus, the VICTUS Femtosecond Laser Platform and the predicate devices have similar safety, effectiveness, and performance profiles.

Non-clinical performance data

A variety of test procedures were conducted to demonstrate the performance of the proposed VICTUS Femtosecond Laser Platform in support of this premarket submission. The collected data were evaluated by comparing the mean values to the specified acceptance criteria and their 95% confidence intervals. Four different materials were used for the bench performance testing: porcine eyes, agarose gel, polyethylene terephthalate (PETG), and polymethyl methacrylate (PMMA). Scanning electronic microscopy has also been utilized to visually assess the results of the laser capsulotomy and flap procedures with the VICTUS Femtosecond Laser Platform. The resulting micrographs are compared qualitatively with images obtained from the predicate devices.

The testing showed that laser-assisted anterior capsulotomy performed with the VICTUS Femtosecond Laser Platform resulted in highly reproducible and accurate capsular tissue diameter, depth, height, and centration. Flaps created with the VICTUS Femtosecond Laser Platform were shown to result in highly accurate tissue diameter, thickness, and centration.

Clinical performance data

Clinical performance was evaluated in a clinical study using the VICTUS Femtosecond Laser Platform (VICTUS) for use in cataract procedures. This study included evaluation of femtosecond laser anterior capsulotomy as compared to manual methods for cataract surgery. This was a randomized, controlled, open, prospective, single-center, multi-surgeon clinical study.

{3}------------------------------------------------

SECTION 5 510(K) SUMMARY OF SAFETY AND EFFECTIVENESS

Enrolled subjects were randomly assigned to one of two groups: Group A had anterior capsulotomy as well as lens fragmentation performed by the VICTUS device prior to phacoemulsification (treatment), and Group B acted as a control group where the capsulotomy was performed manually prior to phacoemulsification.

119 eyes of the 118 subjects were included for analysis (one patient was treated bilaterally). The mean age of the study population was 60.0 ± 10.7 years (from 20 to 81 years). The VICTUS anterior capsulotomy procedure was shown to be comparable to the standard manual procedure capsulorhexis (CCC). The occurrence of adverse event or severe adverse event was not different between the two study groups up to 3-Month post-surgery. Treatment safety was good and slit lamp examinations at one day post-surgery as well as up to 3-Month post-surgery were consistent with those following the manual procedure. The observation rates of corneal edema, flare and trace anterior chamber cells post femto-surgery were comparable to those in the manual group. The centration of the IOL was good as determined by visual inspection during slit lamp examination at one day post-surgery as well as up to 3-Month post-surgery. The study population included cataract grades 1-5 as well as white/brown cataracts which did not pose any additional risks with the VICTUS laser-assisted anterior capsulotomy.

Additional parameters encompassed the completeness of the capsulotomy as well as the centration of the capsulotomy and implanted IOL as determined by visual inspection at the day of surgery. Overall. it can be concluded that the VICTUS can be used successfully for performance of anterior capsulotomy during cataract surgery.

Separately, flap thickness clinical data on 18 eyes was collected at a VICTUS site located outside of the USA. The data provided compared intended flap thickness (in microns) to the achieved flap thickness. The clinical data collected showed that the difference between the achieved mean and the intended mean (3.58um) is within the acceptance criteria of 10μm, with a standard deviation of approximately 6um.

The clinical data provided confirms that laser-assisted anterior capsulotomy is comparable to the standard manual procedure. The occurrence rates for adverse event, severe adverse event and treatment-related complications are comparable to manual capsulotomy.

Conclusion

The technological characteristics of the VICTUS Femtosecond Laser Platform are substantially equivalent to the technological characteristics of the previously cleared FEMTEC Laser Microkeratome (K033354) and the FEMTEC Laser System for Anterior Capsulotomy (K110427). The non-clinical and clinical data support that anterior capsulotomy and flap creation can be successfully executed by the VICTUS Femtosecond Laser Platform.
