Intended Use

The LenSx 550 Laser System is indicated for anterior capsulotomy during cataract surgery.

Device Story

LenSx 550 Laser System is an ophthalmic surgical laser for anterior capsulotomy. It focuses low-energy infrared femtosecond laser pulses into the anterior lens. A computer-controlled scanning system directs the beam in a 3D pattern to create incisions via tissue photodisruption. The system uses an off-the-shelf disposable contact lens to fix the eye relative to the delivery system. Operated by a surgeon in an operating room, the device provides precise, automated capsulotomy creation. The surgeon monitors the procedure via an operating microscope. By replacing manual capsulotomy with a laser-created incision, the device aims to improve the uniformity, accuracy, and predictability of the capsular opening, potentially facilitating safer intraocular lens placement and reducing complications like radial tears.

Clinical Evidence

Prospective, single-center clinical trial evaluating anterior capsulotomy performance during cataract/IOL surgery. Primary endpoints included successful capsulotomy creation, centering, and absence of complications. Results: 100% success rate in capsulotomy completion; no radial tears observed intraoperatively or postoperatively; all IOLs centered; no posterior capsule tears. Bench testing confirmed uniform, accurate, and predictable capsulotomy size/depth in porcine eyes and plastic substrates, with edge smoothness comparable to manual techniques.

Technological Characteristics

Ophthalmic femtosecond laser system; infrared light source; computer-controlled 3D scanning system; disposable contact lens interface. Class II device (21 CFR 886.4390).

Indications for Use

Indicated for anterior capsulotomy during cataract surgery in patients requiring the procedure.

Regulatory Classification

### DEVICE DESCRIPTION

The LenSx 550 Laser is an ophthalmic surgical laser intended for use in patients requiring an anterior capsulotomy. The LenSx 550 Laser focuses a beam of low energy pulses of infrared light into the anterior lens. Consistent with commercially available femtosecond lasers used for lamellar resection of the cornea (GEX, 878.4810), the cutting effect is produced by scanning individual pulses to produce a continuous incision. The location of the tissue photodisruption is controlled by moving the focus of the laser beam to the desired location. A computer-controlled scanning system directs the laser beam throughout a three-dimensional pattern to produce an incision. Finally, the laser pulses are delivered through an off-the-shelf disposable contact lens that contacts the cornea and fixes the eye with respect to the delivery system.

#### STATEMENT OF INTENDED USE

The LenSx 550 Laser System is indicated for anterior capsulotomy during cataract surgery.

### TECHNOLOGICAL CHARACTERISTICS COMPARISON

The LenSx 550 laser shares a similar intended use, and indication for use as the Fugo Blade by Medisurg Research and Management Corp., the Profile 3000 Laser System (K040005), the Burane Laser System (K052806) and the Fontona Dualis Nd:YAG/Er:YAG Laser System (K021548). The LenSx 550 mode of operation and the technology utilized to create the cutting action are similar to the 20/10 Perfect Vision FemTec Laser Microkeratome, and the IntraLase FS Lasers and is therefore substantially equivalent to these legally marketed predicate devices.

## BRIEF SUMMARY OF NONCLINICAL TESTS AND RESULTS

LenSx has developed the LenSx 550 for use in anterior capsulotomy, employing the precision and control of femtosecond lasers for this procedure. Pre-clinical and clinical testing has included bench testing and a prospective, single-center clinical trial.

#### Summary of Pre-Clinical Testing

Testing and analyses performed included accuracy and reproducibility of capsulotomy size and depth in porcine eyes and plastic substrates, as well as scanning electron microscopy. The data demonstrated the LenSx 550 produces anterior capsulotomies that are uniform, accurate and predictable in size over a wide range of depths. The capsular edge created by the LenSx 550 is also at least as smooth as that created during manual anterior capsulotomy.

#### Summary of Clinical Testing

A clinical trial of the LenSx 550 Laser was conducted to evaluate the performance of this laser system in the creation of anterior capsulotomy during cataract/IOL surgery. Anterior capsulotomy was successfully performed in all eyes using the LenSx 550 Laser. i.e., the capsulotomy was complete in all eyes, with no radial tears observed intraoperatively or postoperatively, and with an intraocular lens placed in the capsular bag. Postoperatively, the course of follow-up in the study population was unremarkable, The intraocular lens was centered in all study cyes, and no posterior capsule tears were observed. All capsulotomies were judged to be well centered by the surgeon using visual inspection in the operating microscope.
