No
The description focuses on the laser technology and its mechanical action, with no mention of AI or ML. The performance studies are ex-vivo comparisons to predicate devices, not evaluations of algorithmic performance.
No
The device is used to create corneal incisions for surgical procedures, which are generally considered interventions rather than therapeutic treatments that restore health.
No
The device is described as a surgical femtosecond laser used for creating corneal incisions, indicating it is an interventional/surgical device, not a diagnostic one.
No
The device description explicitly states it is a "femtosecond laser" and describes its physical cutting action, indicating it is a hardware device.
Based on the provided information, the VisuMax Laser Keratome is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs are used to examine specimens derived from the human body. The VisuMax Laser Keratome is a surgical device used to make incisions directly on the patient's cornea. It does not analyze or test samples taken from the body.
- The intended use is surgical. The indications for use clearly describe surgical procedures on the cornea (LASIK, lamellar keratoplasty, penetrating keratoplasty, corneal harvesting).
- The device description details a surgical laser. It describes a femtosecond laser used for cutting tissue through photodisruptions.
Therefore, the VisuMax Laser Keratome falls under the category of a surgical device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use

Device Description
The VisuMax Laser Keratome is an ophthalmic surgical femtosecond laser intended for use in patients requiring corneal incisions. The cutting action of the VisuMax Laser Keratome is achieved through precise individual micro-photodisruptions of tissue, created by tightly focused ultrashort pulses which are delivered through a disposable applanation lens while fixating the eye under very low vacuum.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The VisuMax Laser keratome has been designed and tested to applicable safety standards. The performance data supporting safety and substantial equivalence of the VisuMax Laser Keratome to the predicate devices are summarized as follows:
- Ex-vivo porcine eye studies demonstrate the accuracy and reproducibility of the VisuMax Laser Keratome for lamellar keratoplasty incisions and that the level of precision is maintained over a wide range of incision diameters and depths. The results further demonstrate that the proposed device performed equivalently to the predicate device.
- Ex-vivo study in human globes shows that the quality of the full penetrating keratoplasy performance of the VisuMax Laser Keratome and the predicate device are comparable.

DEVICE DESCRIPTION
The VisuMax Laser Keratome is an ophthalmic surgical femtosecond laser intended for use in patients requiring corneal incisions. The cutting action of the VisuMax Laser Keratome is achieved through precise individual micro-photodisruptions of tissue, created by tightly focused ultrashort pulses which are delivered through a disposable applanation lens while fixating the eye under very low vacuum.
STATEMENT OF INTENDED USE
The VisuMax Laser Keratome is indicated for the following:
- . In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea;
- In patients undergoing surgery or other treatment requiring initial lamellar . resection of the cornea;
- In the creation of a lamellar cut/resection of the cornea for lamellar . keratoplasty:
- In the creation of a cut/incision for penetrating keratoplasty and corneal . harvesting.
TECHNOLOGICAL CHARACTERISTICS COMPARISON
The VisuMax Laser Keratome laser is substantially equivalent to the HORUS Laser Keratome also by Carl Zeiss Meditec (K062314), as well as the IntraLase FS Laser (K041893) by Abbott Medical Optics.
The VisuMax Laser Keratome has the same operating characteristics as the predicate devices, the HORUS (5062314), and the IntraLase FS Lasers (K993153, K001211, K002890. K013941. K031960. K041893. K060372. K063682. and K073404). Therefore, the VisuMax Laser Keratome is substantially equivalent to these legally marketed predicate devices.
SUMMARY OR PROPOSED MODIFICATIONS INCLUDED IN THIS 510(K) PREMARKET NOTIFICATION
The subject of this traditional premarket notification 510(k) is the expansion of the indications for use of the predicate device (HORUS Laser Keratome) to include lamellar keratoplasty and penetrating keratoplasty, consistent with the indication for use of the predicate device for other commercially available femtosecond lasers. The indications for use for the VisuMax Laser Keratome would be the same as those for the predicate device (the IntraLase FS Laser).
2
Additionally, modifications have been introduced to the device hardware and software specifications in order to allow for the addition of the lamellar and penetrating keratoplasty capability and to enhance the laser's usability in the clinic setting.
These modifications include:
- An increase in pulse repetition rate from 200 kHz to 500 kHz to allow the . femtosecond resections and/or incisions to be performed with acceptable procedure times
- An increase in the maximum average laser power as a result of the higher pulse . repetition rate, however the total laser energy delivered to the eye is unchanged
- Reduction of the maximum laser pulse peak power and the therapy pulse energy .
- The addition of a trackball and touch screen to the GUI .
- Improved ergonomics of the Patient Supporting System and to the laser housing . to facilitate the ease of use
- An additional slit projector to facilitate better patient handling .
- An additional IR light source to improve illumination of the surgical field .
BRIEF SUMMARY OF PRE-CLINICAL AND CLINICAL PERFORMANCE TESTING
The VisuMax Laser keratome has been designed and tested to applicable safety standards. The performance data supporting safety and substantial equivalence of the VisuMax Laser Keratome to the predicate devices are summarized as follows:
- Ex-vivo porcine eye studies demonstrate the accuracy and reproducibility of the . VisuMax Laser Keratome for lamellar keratoplasty incisions and that the level of precision is maintained over a wide range of incision diameters and depths. The results further demonstrate that the proposed device performed equivalently to the predicate device.
- Ex-vivo study in human globes shows that the quality of the full penetrating . keratoplasy performance of the VisuMax Laser Keratome and the predicate device are comparable.
CONCLUSION
The VisuMax Laser Keratome is substantially equivalent to the predicate devices.
