The VICTUS Femtosecond Laser Platform is 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
- for anterior capsulotomy during cataract surgery
- the creation of penetrating arcuate cuts / incisions in the cornea in patients undergoing cataract surgery or other ophthalmic treatment requiring penetrating arcuate cuts / incisions in the cornea.
The VICTUS Femtosecond Laser Platform (hercafter referred to as the VICTUS Platform) is a precision ophthalmic surgical laser indicated for use in patients undergoing cataract surgery or other ophthalmic treatment requiring penetrating arcuate cuts / incisions in the cornea.
The VICTUS Platform is an ophthalmic surgical femtosecond laser designed for cutting a penetrating arcuate cut of pre-selected depth, radius, opening angle, and position angle. The system works by first being programmed with the depth, radius, opening angle and position angle at which the penetrating arcuate cut is desired. The surgeon then fixates the eye with a sterile disposable PMMA contact lens (hercafter referred to as the Patient Interface) that is connected to the laser via a vacuum tube. Depths of -120µm, radius of 1500 - 4750 um, opening angles of 1-360°, and position angles of 0 - 359° are available.
Laser pulses are delivered through the sterile 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.
Here's a breakdown of the acceptance criteria and the study details for the VICTUS Femtosecond Laser Platform, based on the provided text:
1. Acceptance Criteria and Reported Device Performance
The provided text does not explicitly state quantitative acceptance criteria in a table format for the arcuate cuts/incisions. However, the performance data section implies the following outcomes were evaluated and met a criteria of being "highly reproducible and accurate." The postmarket surveillance review indicates "comparability to the standard manual procedure" for clinical endpoints.
| Acceptance Criteria (Implied/Evaluated) | Reported Device Performance (VICTUS Femtosecond Laser Platform) |
|---|---|
| Bench/Pre-Clinical Testing: | |
| Reproducibility of rim depth | Highly reproducible |
| Accuracy of rim depth | Accurate |
| Reproducibility of diameter | Highly reproducible |
| Accuracy of diameter | Accurate |
| Reproducibility of open angle | Highly reproducible |
| Accuracy of open angle | Accurate |
| Reproducibility of position angle | Highly reproducible |
| Accuracy of position angle | Accurate |
| Reproducibility of centration | Highly reproducible |
| Accuracy of centration | Accurate |
| Visual comparison to predicate devices | Qualitatively comparable (based on scanning electron microscopy) |
| Postmarket Surveillance Review (Clinical): | |
| Post-surgical loss of lines of BCDVA | Comparable to standard manual procedure |
| Post-surgical overall change in refraction | Comparable to standard manual procedure |
| Postoperative induced cylinder | Comparable to standard manual procedure |
| Adverse events (rate and type) | Comparable to standard manual procedure |
| Serious adverse events (rate and type) | Comparable to standard manual procedure |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size for Test Set: 49 eyes from 34 subjects.
- Data Provenance: Retrospective, single site in Europe.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications
The text states that "all surgeries were performed by the same surgeon" at the single clinical location. This surgeon's performance was compared between manual and laser-assisted procedures. While this surgeon's outcomes define the "ground truth" for the comparison within the study, the text does not specify the number of experts or their qualifications that established an independent "ground truth" for evaluating the quality of the surgical outcomes themselves. The comparison is against the surgeon's own manual technique.
4. Adjudication Method for the Test Set
The provided text does not specify an adjudication method (e.g., 2+1, 3+1). The "ground truth" appears to be the clinical outcomes as assessed by the operating surgeon and the postmarket surveillance review.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No, a multi-reader multi-case (MRMC) comparative effectiveness study was not explicitly described. The study compared laser-assisted procedures to manual procedures performed by the same surgeon at a single site. The effect size of how much human readers improve with AI vs. without AI assistance is not applicable in this context as the device is a surgical laser, not an AI diagnostic tool.
6. If a Standalone Study (Algorithm Only Without Human-in-the-Loop Performance) was done
Yes, a standalone performance evaluation was conducted in the Non-Clinical Performance Data section. This involved bench testing using various materials (porcine eyes, agarose gel, PETG, and PMMA) and scanning electron microscopy to assess the laser's cutting accuracy and reproducibility. This evaluate the device's inherent mechanical and cutting capabilities independent of human intervention in the cutting process itself.
7. The Type of Ground Truth Used
- For Non-Clinical Performance Data: The ground truth was established through measurements (rim depth, diameter, open angle, position angle, centration) and visual assessment (scanning electron microscopy) of the cuts produced in various test materials (porcine eyes, agarose gel, PETG, PMMA).
- For Postmarket Surveillance Clinical Review: The ground truth was based on clinical outcomes data (post-surgical loss of best corrected distance visual acuity (BCDVA), post-surgical overall change in refraction, postoperative induced cylinder, adverse events, and serious adverse events) observed in patients after both laser-assisted and manual arcuate incisions, as assessed by the operating surgeon.
8. The Sample Size for the Training Set
The provided text does not mention a training set or details about its sample size. This device is a surgical laser, and the studies described are performance evaluations, not the development or training of an AI algorithm.
9. How the Ground Truth for the Training Set Was Established
As no training set is mentioned (since this is not an AI/algorithm-driven device in the context of typical AI device submissions), this question is not applicable.

Description of the Device Subject to Premarket Notification:
The VICTUS Femtosecond Laser Platform (hercafter referred to as the VICTUS Platform) is a precision ophthalmic surgical laser indicated for use in patients undergoing cataract surgery or other ophthalmic treatment requiring penetrating arcuate cuts / incisions in the cornea.
The VICTUS Platform is an ophthalmic surgical femtosecond laser designed for cutting a penetrating arcuate cut of pre-selected depth, radius, opening angle, and position angle. The system works by first being programmed with the depth, radius, opening angle and position angle at which the penetrating arcuate cut is desired. The surgeon then fixates the eye with a sterile disposable PMMA contact lens (hercafter referred to as the Patient Interface) that is connected to the laser via a vacuum tube. Depths of -120µm, radius of 1500 - 4750 um, opening angles of 1-360°, and position angles of 0 - 359° are available.
Laser pulses are delivered through the sterile 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.
Indications for Use:
The VICTUS Platform is 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
- for anterior capsulotomy during cataract surgery .
- the creation of penetrating arcuate cuts / incisions in the cornea in patients undergoing ● cataract surgery or other ophthalmic treatment requiring penetrating arcuate cuts / incisions in the cornea.
Technical Characteristics Comparison:
The design principle of the VICTUS Platform is fundamentally the same as the predicate devices. The VICTUS Platform mode of operation is the same as the previously cleared VICTUS Femtosecond Laser Platform cleared in K120426, iFS Laser System cleared in K113151, and the LenSx Laser System cleared in K101626, all of which deliver femtosecond pulses to produce a pattern of photodisruption to create cuts / separation in ophthalmic tissue. The VICTUS Platform delivers femtosecond pulses to produce a pattern of photodisruption for creation of penetrating arcuate cuts / incisions in the cornea, as do the predicate devices.
The means of fixation of the patient contact portion of the VICTUS Platform is substantially equivalent to that present in the VICTUS Femtosecond Laser Platform cleared in K120426, the Femtec Laser System for Anterior Capsulotomy cleared in K110427, iFS Laser System cleared in K113151, and the LenSx Laser cleared in K101626. All of these predicate systems use suction vacuum to affix a suction ring to the corneal surface prior to use.
{2}------------------------------------------------
The VICTUS Platform mode of operation and the technology used to create the cutting action are similar or identical to these previously mentioned devices, and therefore substantially equivalent to these legally marketed predicate devices.
Performance Data:
The VICTUS Femtosecond Laser Platform has undergone testing and is in compliance with applicable safety standards as listed in the following table.
| Standard | Title |
|---|---|
| EN ISO 60601-1 | Medical electrical equipment - Part I: General requirementsfor safety |
| EN ISO 60601-1-2 | Medical electrical equipment - Part 1: General requirementsfor safety; 2. Collateral standard: electromagneticcompatibility; requirements and tests |
| EN ISO 60601-1-4 | Medical electrical equipment - Part 1-4: General requirementsfor safety; Collateral standard: Programmable electricalmedical systems |
| EN ISO 60601-2-22 | Medical electrical equipment – Part 2: Particular requirementsfor the safety of diagnostic and therapeutic laser equipment |
The VICTUS Femtosecond Laser Platform has been found to perform equivalently to the predicate devices in patients undergoing ophthalmic surgery or other treatment requiring penetrating arcuate cuts / incisions in the cornea. The VICTUS Femtosecond Laser Platform and the predicate devices therefore have similar performance profiles.
Non-Clinical Performance Data
A variety of test procedures were conducted to demonstrate the performance of the proposed VICTUS 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 arcuate cuts / incisions procedures with the VICTUS Platform. The resulting micrographs are compared qualitatively with images obtained from the predicate devices.
The testing showed that laser-assisted arcuate cuts / incisions performed with the VICTUS Femtosecond Laser Platform resulted in highly reproducible and accurate rim depth, diameter, open angle, position angle, and centration.
{3}------------------------------------------------
Postmarket Surveillance Clinical Review
A retrospective postmarket surveillance review was performed at a single site in Europe to compare manual arcuate incisions using a diamond blade to laser-assisted arcuate incisions using the VICTUS™ Platform. This review was conducted at a single clinical location, and all surgeries were performed by the same surgeon.
A total of 49 eyes in 34 subjects were included in the analysis. The mean age of the study population was 57.4 ± 11.7 years (range: 18 to 84 years). Twenty four (24) eyes received laserassisted arcuate cuts, of which 11 received arcuate cuts alone and 13 received both arcuate cuts and cataract surgery. Twenty five (25) eyes received manual arcuate cuts, of which four received arcuate cuts alone and 21 received both arcuate cuts and cataract surgery. One adverse event was reported in the laser-assisted group, which was considered by the surgeon to not be related to the laser-assisted procedure.
The laser-assisted arcuate cuts procedure was shown to be comparable to the standard manual procedure when assessed for common clinical endpoints such as post-surgical loss of lines of best corrected distance visual acuity (BCDVA), post-surgical overall change in refraction, postoperative induced cylinder, adverse events, and serious adverse events.
The postmarket surveillance review data confirm that laser-assisted arcuate cuts are comparable to the standard manual procedure.
Basis for Determination of Substantial Equivalence:
The technological characteristics of the VICTUS Femtosecond Laser Platform are substantially equivalent to the technological characteristics of the VICTUS Femtosecond Laser Platform (K120426), the Femtec Laser System for Anterior Capsulotomy (K110427), iFS Laser System (K113151), the LenSx Laser (K101626).
The proposed additional indication for use of arcuate cuts / incisions for the VICTUS Femtosecond Laser Platform is very similar to the indications for use cleared for the iFS Femtosecond Laser in K113151 and for the LenSx Laser in K101426; both include arcuate corneal incisions.
