The description focuses on the laser technology and computer-controlled scanning system for precise tissue manipulation, with no mention of AI or ML for decision-making, image analysis, or pattern recognition beyond pre-programmed patterns.
Yes.
This device is used to perform surgical procedures (corneal cuts, anterior capsulotomy, laser phacofragmentation) to treat medical conditions, specifically cataracts and for LASIK surgery, which are therapeutic interventions.
No
The device description clearly states its purpose as creating incisions and separating tissue using focused femtosecond laser pulses for surgical procedures like cataract surgery and LASIK. It performs actions, rather than diagnosing conditions.
No
The device description explicitly details hardware components, including a laser system, patient interface accessories (applanating lens and suction ring assembly), and mentions hardware modifications and verification. This indicates it is a physical device with integrated software, not a software-only medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The LenSx Laser System is a surgical laser used to perform procedures directly on the eye (cornea, lens capsule, crystalline lens). It is an in vivo device, meaning it operates within the living body.
- Intended Use: The intended use clearly describes surgical procedures performed on the eye, not the analysis of specimens taken from the body.
- Device Description: The description details a surgical laser system and accessories used for direct interaction with the eye tissue.
Therefore, the LenSx Laser System falls under the category of a surgical device, not an In Vitro Diagnostic device.

Intended Use / Indications for Use
The LenSx Laser System is indicated for use:
- In the creation of corneal cuts/incisions (single-plane, multi-plane and arcuate), anterior capsulotomy and laser phacofragmentation during cataract surgery. Each of these procedures may be performed either individually or consecutively during the same surgery.
- In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea.

Device Description
The LenSx Laser System is an ophthalmic surgical laser which uses focused femtosecond laser pulses to create incisions and to separate tissue within the lens capsule, crystalline lens, and the cornea. A femtosecond light pulses is focused into a sufficiently small spot in order to achieve photodisruption of the tissue inside the focus. A tiny volume of tissue, a few microns in diameter, is thereby photodisrupted at the laser focus. A computer-controlled scanning system directs the focused laser beam throughout a threedimensional pattern to produce an incision. The surgical effect is produced by scanning thousands of individual pulses per second to produce a continuous incision or tissue separation.
The laser pulses are delivered through a Patient Interface accessory that is placed on the surface of the cornea and fixes the position of the eye with respect to the delivery system. Two models of the Patient Interface accessory are offered for use with the LenSx Laser System: the LenSx Laser Patient Interface and the LenSx SoftFit Patient Interface. Both models consist of a sterile, disposable applanating lens and suction ring assembly that contacts the cornea and fixes the eye with respect to the delivery system. In addition, LenSx SoftFit Patient Interface model comes with a soft contact lens that is positioned against the internal surface of the patient Interface glass. For cataract procedures, the LenSx SoftFit Patient Interface is used. For corneal flap procedures, the LenSx Laser Patient Interface is used.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The performance data supporting substantial equivalence of the LenSx Laser with the above modifications include:
- Evaluation of the accuracy and reproducibility of the depths and geometry of each of the previously cleared treatment patterns using the modified LenSx Laser in comparison to acceptance criteria established for the predicate LenSx Laser.
- Evaluation of the accuracy and reproducibility of energy stability using the modified LenSx Laser in comparison to acceptance criteria established for the predicate LenSx Laser.
Non-clinical performance testing demonstrated that:
- The modified LenSx Laser delivers a high degree of accuracy and reproducibility for the creation of corneal flaps suitable for LASIK compared to the predicate devices.
- The modified LenSx Laser delivers a high degree of accuracy and reproducibility for the creation of phacofragmentation patterns, including lens fragmentation treatments, capsulotomy treatments and corneal incisions/cuts.
- The modified LenSx Laser delivers a high degree of accuracy and reproducibility in the generation of laser pulse energies up to 2.6 uJ (for 150 kHz) and 15 uJ (for 50 kHz).
- Hardware modifications were verified to demonstrate equivalence of the modified device to the predicate devices. All hardware modifications met required verification criteria.
The scope of the software and hardware modification did not require clinical testing to establish safety and effectiveness of the modified device.

Description of Safety and Substantial Equivalence:
The subject of this Traditional 510(k) premarket notification is the software and hardware modifications to the LenSx Laser System and the removal of the indication for lamellar keratoplasty from the Indications for Use statement. All modifications were tested to show substantial equivalence to the predicate devices and do not alter the safety and effectiveness of the devices.
The LenSx Laser System is essentially the same device as the predicate LenSx Laser System. These modifications are categorized as follows:
- Hardware updates to improve manufacturability and serviceability. Hardware ● modifications to implement switchable laser operation at 50 or 150 kHz.
- . Software updates to implement the use of a planner Ethernet device for cataract surgery, re-enabling flap functionality that was previously cleared, and introducing an optional lens fragmentation pattern whose parameters are within previously cleared treatment ranges.
- Labeling updates to the operator's manual to reflect the implementation of the ● changes described above.
- . A revised Indications for Use statement that removes the indication for lamellar keratoplasty.
- . Extension of shelf-life to two (2) years for the sterile disposable LenSx Laser SoftFit Patient Interface.
All modifications were tested to show substantial equivalence to the predicate devices and do not alter the safety and effectiveness of the devices. Table A summaries the substantial equivalence between the modified device and the predicate devices.
