No
The description focuses on the laser technology and computer-controlled scanning system for precise tissue manipulation, with no mention of AI or ML for image analysis, decision-making, or pattern recognition beyond pre-programmed surgical patterns.
Yes
The device is used to perform surgical procedures (anterior capsulotomy, phacofragmentation, keratoplasty) on the eye to treat conditions like cataracts and corneal diseases, which are therapeutic interventions.
No
The device is an ophthalmic surgical laser used to create incisions and separate tissue in the eye, which describes a therapeutic/surgical function, not a diagnostic one.
No
The device description explicitly details a laser system with physical components (laser pulses, scanning system, disposable applanating lens, suction ring assembly) that interact directly with tissue. This is a hardware-based medical device, not software-only.
Based on the provided information, the LenSx Laser 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 Function: The LenSx Laser is a surgical device that uses focused laser pulses to create incisions and separate tissue directly within the patient's eye during procedures like cataract surgery and keratoplasty. It is performing a surgical action on living tissue, not analyzing a specimen taken from the body.
- Intended Use: The intended uses described are surgical procedures performed on the eye, not diagnostic tests on biological samples.
Therefore, the LenSx Laser falls under the category of a surgical device, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The LenSx Laser System is indicated for anterior capsulotomy and laser phacofragmentation during cataract surgery and for the creation of a partial thickness cut/incision for lamellar keratoplasty and in the creation of a full-thickness cut/incision for penetrating keratoplasty and for cataract surgery. Each of these procedures may be performed either individually or consecutively during the same surgery.
The LenSx Laser is indicated for use in patients undergoing cataract surgery for removal of the crystalline lens. Intended uses in cataract surgery include anterior capsulotomy, phacofragmentation, and the creation of single plane and multi-plane arc cuts/incisions in the cornea, each of,which may be performed either individually or consecutively during the same procedure.
The LenSx Laser is indicated for use in patients undergoing penetrating keratoplasty for full thickness corneal replacement and in patients undergoing lamellar keratoplasty for partial thickness corneal replacement. The intended use in penetrating and lamellar keratoplasty includes the creation of single plane and multi-plane arc and circular cuts/incisions in the cornea.

Device Description
The LenSx Laser System uses focused femtosecond laser pulses to create incisions and separates tissue in the lens capsule, crystalline lens and 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 incisions 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 sterile, disposable applanating lens and suction ring assembly that contacts the cornea and fixes the eye with respect to the delivery system.
The LenSx Laser is an ophthalmic surgical laser that has previously been cleared for use in:
• Anterior capsulotomy (K082947), performed by delivering a cylindrical pattern of laser pulses to intersect the anterior lens capsule.
· Phacofragmentation (K090452), performed by delivering series of laser pulses to form two intersecting ellipsoidal planes that divides the lens into quadrants.
. Cuts/incisions for keratoplasty (K092647) which are performed by delivering a pattern of circles and arcs with programmable incision length and depth.
