No
The device description clearly details a laser system with physical components, including a patient interface accessory, which are hardware. The 510(k) is specifically for an accessory to this hardware system.
Based on the provided information, the LenSx Laser System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- LenSx Laser System Function: The LenSx Laser System is a surgical device that uses a laser to perform procedures directly on the eye (cornea, lens capsule, crystalline lens). It is used for creating incisions and separating tissue in vivo (within the living body), not for analyzing specimens in vitro (outside the living body).
- Intended Use: The intended uses listed are all surgical procedures performed directly on the patient's eye.
- Device Description: The description details a surgical laser system and its accessories used for performing these procedures.
- Lack of IVD Indicators: There is no mention of collecting or analyzing biological specimens, diagnostic testing, or providing information for diagnosis based on laboratory analysis.
Therefore, the LenSx Laser System is a surgical device, not an In Vitro Diagnostic device.

Device Description
The LenSx Laser System uses focused femtosecond laser pulses to create incisions and separate tissue in the lens capsule, crystalline lens, and the cornea. Individual photodisruption locations are controlled by repeatedly repositioning the laser focus. The light pulse 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. The surgical effect is produced by scanning thousands of individual pulses per second to produce a continuous incision or tissue separation.
The location of the tissue photodisruption is controlled by moving the focus of the laser beam to the desired surgical target location. A computer-controlled scanning system directs the laser beam throughout a three-dimensional pattern to produce an incision. The laser pulses are delivered through a Patient Interface accessory that is placed on the surface of the cornea and fixes the eye with respect to the delivery system.
This 510(k) premarket notification is being submitted to seek clearance for an additional patient interface accessory to be offered for use with cataract procedures in addition to the original patient interface accessory to the LenSx Laser System (cleared under K120732 for cataract and lamellar resection procedures). The SoftFit Patient Interface differs from the original Patient Interface (K120732) in that it has an extended suction ring skirt that enables positioning of a soft contact lens against the internal surface of the patient interface glass. The soft contact lens is similar to a standard daily wear contact lens indicated for the correction of ammetropia, with a slightly modified edge to enable fitting into the SoftFit Patient Interface. The materials and manufacturing processes used for the soft contact lens component of the proposed SoftFit Patient Interface accessory are identical to the processes used for the predicate daily wear soft contact lens (K100244).
With the soft contact lens insert in place, the SoftFit Patient Interface is then mounted onto the LenSx laser system for docking onto the eye in a manner that is identical to the original LenSx Laser Patient Interface. As a result, use of the soft contact lens substantially reduces intraocular pressure (IOP) during the laser procedure, enhancing comfort and addressing potential concerns in patients with a history of glaucoma.
For cataract procedures, either a LenSx Laser Patient Interface or a SoftFit Patient Interface may be used. The original LenSx Laser Patient Interface is used for keratoplasty and corneal flaps.

DEVICE DESCRIPTION 4.4
The LenSx Laser System uses focused femtosecond laser pulses to create incisions and separate tissue in the lens capsule, crystalline lens, and the cornea. Individual photodisruption locations are controlled by repeatedly repositioning the laser focus. The light pulse 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. The surgical effect is produced by scanning thousands of individual pulses per second to produce a continuous incision or tissue separation.
The location of the tissue photodisruption is controlled by moving the focus of the laser beam to the desired surgical target location. A computer-controlled scanning system directs the laser beam throughout a three-dimensional pattern to produce an incision. The laser pulses are delivered through a Patient Interface accessory that is placed on the surface of the cornea and fixes the eye with respect to the delivery system.
This 510(k) premarket notification is being submitted to seek clearance for an additional patient interface accessory to be offered for use with cataract procedures in addition to the original patient interface accessory to the LenSx Laser System (cleared under K120732 for cataract and lamellar resection procedures). The SoftFit Patient Interface differs from the original Patient Interface (K120732) in that it has an extended suction ring skirt that enables positioning of a soft contact lens against the internal surface of the patient interface glass. The soft contact lens is similar to a standard daily wear contact lens indicated for the correction of ammetropia, with a slightly modified edge to enable fitting into the SoftFit Patient Interface. The materials and manufacturing processes used for the soft contact lens component of the proposed SoftFit Patient Interface accessory are identical to the processes used for the predicate daily wear soft contact lens (K100244).

As a result, use of the soft contact lens substantially reduces intraocular pressure (IOP) during the laser procedure, enhancing comfort and addressing potential concerns in patients with a history of glaucoma.
For cataract procedures, either a LenSx Laser Patient Interface or a SoftFit Patient Interface may be used. The original LenSx Laser Patient Interface is used for keratoplasty and corneal flaps.

INDICATION FOR USE 4.5
The following indications for use for the LenSx Laser System are unchanged from the previously cleared device (K120732):
- · In the creation of corneal cuts/incisions, 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 lamellar cut/resection for lamellar keratoplasty, and in the creation of a penetrating cut/incision for penetrating keratoplasty
- · In the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea
TECHNOLOGICAL CHARACTERISTICS COMPARISON 4.6
The LenSx Laser is unchanged and this 510(k) is intended to introduce an alternative Patient Interface accessory (the SoftFit Patient Interface) for use with cataract surgery procedures. The original Patient Interface (cleared under K120732) will continue to be available for use with cataract, keratoplasty and corneal flap procedures.
The SoftFit Patient Interface consists of a slightly modified Patient Interface and a daily wear soft contact lens insert. The SoftFit PI has an extended suction ring skirt that enables positioning of the contact lens against the internal surface of the patient interface glass. The soft contact lens is identical to standard daily wear contact lens indicated for the correction of ammetropia (K100244), with a slightly modified edge to enable fitting into the SoftFit Patient Interface. The outer curvature of the soft contact lens matches the internal curvature of the patient interface glass. The inner curvature of the soft contact lens approximates the average corneal curvature. With the soft contact lens in place, the SoftFit Patient Interface is then mounted onto the LenSx Laser system for docking onto the eye in a manner that is identical to the original Patient Interface. The SoftFit Patient Interface results in a significantly lower intraocular pressure elevation during the laser procedure than the original Patient Interface.
BRIEF SUMMARY OF PERFORMANCE TEST RESULTS 4.7
The performance data supporting substantial equivalence of the SoftFit Patient Interface accessory include:
- Evaluation of the holding force and average intraocular pressure increase . generated by original and SoftFit Patient Interfaces.
- Evaluation of the accuracy and reproducibility of the depths and geometry of each . of the previously cleared cataract treatment patterns for the LenSx Laser when the SoftFit Patient Interface is used.
