No
The description focuses on precise measurements and customized patterns based on those measurements, but there is no mention of learning, adaptation, or complex pattern recognition that would typically indicate AI/ML. The customization appears to be based on direct measurements rather than learned algorithms.
Yes.
The device is used to perform anterior capsulotomy and laser phaco fragmentation during cataract surgery, which are therapeutic procedures to treat cataracts and aid in their removal.
No
The device is an ophthalmic surgical laser used for anterior capsulotomy and laser phaco fragmentation during cataract surgery. While it includes an optical measuring system for customization, its primary function is therapeutic (cutting/fragmenting), not diagnostic.
No
The device description clearly states it is an ophthalmic surgical laser system that generates laser pulses and includes a built-in optical measuring system and eye docking device, indicating it is a hardware-based medical device.
Based on the provided information, the LensAR Laser System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens derived from the human body (like blood, urine, tissue) outside of the body to provide information for diagnosis, monitoring, or screening.
- LensAR Laser System Function: The LensAR Laser System is a surgical laser used directly on the patient's eye during cataract surgery. It performs procedures like anterior capsulotomy and laser phaco fragmentation.
- Lack of Specimen Analysis: The device does not analyze any biological specimens taken from the patient. Its function is to physically alter the lens and capsule within the eye.
Therefore, the LensAR Laser System falls under the category of a surgical device, not an In Vitro Diagnostic device.

Device Description
The LensAR Laser System is an ophthalmic surgical laser that has already been cleared for use in anterior capsulotomy in cataract surgery (K090633). It is now intended for additional use in anterior capsulotomy and laser phacofragmentation in cataract surgery, performed individually or consecutively during the same surgery.
The LensAR Laser generates ultrashort laser pulses that are scanned in a three-dimensional pattern in the eye to cut the anterior capsulotomy and to pre-cut the lens into small pieces for easy removal by conventional ultrasound phaco fragmentation. The fragmentation pattern is customized to the patient's eye based on precise measurement of the size, shape and position of the patient's lens by a built-in optical measuring system. During the measurement and subsequent application of the laser pulses, the eye is positioned and immobilized by an off-the-shelf suction ring assembly which is affixed to the eye and which is in turn docked to a refractive index matching eye docking (IMED) device mounted to the laser system.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Summary of Pre-Clinical Testing:
Testing and analyses performed included accuracy and reproducibility of capsulotomy and laser phaco fragmentation incisions in porcine eyes and plastic substrates. The data demonstrated that the LensAR produces anterior capsulotomies and laser phaco fragmentation incision patterns that are accurate and predictable in size and shape. Additional safety testing comparing the acoustic and thermal characteristics of the device to predicate ultrasound phaco emulsification devices demonstrated a safe operating profile with respect to these parameters. Evaluation on ex vivo porcine eyes confirmed the safety with respect to corneal endothelium.
Summary of Clinical Studies:
A prospective clinical study was performed outside the U.S. to evaluate clinical performance. A total of 88 subjects were treated with either a laser anterior capsulotomy/laser lens fragmentation, or a laser fragmentation/manual continuous curvilinear capsulorhexis (CCC), followed if needed by further standard ultrasound lens fragmentation and then irrigation aspiration of the lens in one eye. The eye selection in each patient was the one having the worse cataract condition. In patients needing bilateral cataract removal, the contralateral (fellow eye) of the patient was treated with conventional CCC and ultrasound phacofragmentation at some point after the first eye surgery.
The Primary cohort underwent initial laser phacofragmentation or laser anterior capsulotomy and phacofragmentation using the LensAR Laser, followed if needed by phacoemulsification using ultrasound with the Alcon Series Infiniti System.
A Control Cohort of contralateral eyes in these subjects underwent CCC/phacofragmentation and phacoemulsification with the Alcon Infiniti (predicate device), using a torsional mode, a method demonstrated in the literature to significantly reduce ultrasound power requirements as compared to earlier ultrasound longitudinal devices.

DEVICE DESCRIPTION
- 1
The LensAR Laser System is an ophthalmic surgical laser that has already been cleared for use in anterior capsulotomy in cataract surgery (K090633). It is now intended for additional use in anterior capsulotomy and laser phacofragmentation in cataract surgery, performed individually or consecutively during the same surgery.
The LensAR Laser generates ultrashort laser pulses that are scanned in a three-dimensional pattern in the eye to cut the anterior capsulotomy and to pre-cut the lens into small pieces for easy removal by conventional ultrasound phaco fragmentation. The fragmentation pattern is customized to the patient's eye based on precise measurement of the size, shape and position of the patient's lens by a built-in optical measuring system. During the measurement and subsequent application of the laser pulses, the eye is positioned and immobilized by an off-the-shelf suction ring assembly which is affixed to the eye and which is in turn docked to a refractive index matching eye docking (IMED) device mounted to the laser system.
STATEMENT OF INTENDED USE
The LensAR Laser System is indicated for anterior capsulotomy and laser phaco fragmentation during cataract surgery. The anterior capsulotomy and laser phaco fragmentation procedures may be performed either individually or consecutively during the same surgery.
TECHNOLOGICAL CHARACTERISTICS COMPARISON
The LensAR Laser System proposed for use in phacofragmentation is identical with respect to all technological characteristics to the previously cleared LensAR for use in anterior capsulotomy (K090633). Substantial equivalence is also drawn to previously cleared phacofragmentation systems.
As described in K090633, anterior capsulotomy is performed by delivering a cylindrical pattern of laser pulses to intersect the anterior lens capsule. In the laser phaco fragmentation procedure, the lens is divided into a number of radial sections, similar in shape to those created by the conventional manual "phaco chop" technique (Chop), and then further divided by applying a set of concentric cylindrical cuts through the radial sections (Cylinder).
Following the laser procedure and entry into the eye by conventional means, the fragmented nuclear sections created by the LensAR Laser are further fragmented by ultrasound if necessary, and removed using a standard phacoemulsification probe and aspiration.
Predicate devices include laser and ultrasound phacoemulsification devices cleared for phacofragmentation, such as the Alcon Series Infiniti System (Alcon Laboratories, Inc., K021566 and K082845) and the LenSx Laser 550 (K082947 and K094052). Ultrasound phacofragmentation devices utilize a piezoelectric ultrasonic source that generates similar acoustic and cavitation effects that, along with mechanical effects from the probe, result in
2
phacofragmentation. The LenSx Laser works in the same technical manner as that described above for the LensAR device.
The LensAR Laser's ultrashort, photo disruptive pulses are of sufficiently low energy that the system can accomplish phaco fragmentation while transmitting to surrounding tissue only a tiny fraction of the ultrasonic shockwaves/energy generated by handheld ultrasound phaco fragmentation probes. The laser treatment is applied directly to the crystalline lens through the cornea without the necessity of creating an external wound.
BRIEF SUMMARY OF PRECLINICAL AND CLINICAL PERFORMANCE TEST RESULTS
The performance data supporting substantial equivalence of the LensAR Laser system to the predicate devices are summarized as follows:
