Autonomous LADARVision Laser System


Overall Rating:  A


Overview:  Autonomous LADARVision is unquestionably one of the most sophisticated and precise laser systems available today.  Accuracy and reproducibility of the Autonomous laser technology is unparalleled in the industry by virtue of the highly advanced laser radar tracking system incorporated into the laser platform.   In fact, the Autonomous corporation, in the development of its laser system, drew heavily from technology developed by NASA for high-speed space docking as well as missile tracking technology generated by the Strategic Defense Initiative (Star WARS) specifically for Ballistic Missile Defense.


Eye Tracking Technology:  Clinical studies with older laser platforms had clearly demonstrated that poor patient fixation during excimer laser surgery due to voluntary or involuntary eye movements could result in decentered treatments and suboptimal surgical results.  Eye tracking technology eliminates surgical errors related to patient eye movement or movements of the patient’s head related to rapid heart pulse rate or deep breathing.  Applying Doppler and range imaging laser radar to this problem ultimately allowed Autonomous to become the industry leader in the arena of excimer laser technology that tracked the human eye in real time during a surgical procedure.  No other laser system in the world compares in speed, safety and accuracy to the platform developed by the Autonomous research team. 


    Although other laser systems have developed eye-tracking systems, only Autonomous has a tracking system that measures eye movement 4,000 times each second and is capable of following patient eye movements regardless of how rapid or erratic they may be.

Compare Laser Eye Surgery Systems

Many people are surprised to learn that all laser systems are not the same. They all use laser beams to reshape the cornea. But there are important differences in technology from one system to another. Because these differences could affect the laser eye surgery procedure, it's important to understand why the technology matters.

These charts show you some of the ways that laser systems differ from each other. Here, we list the features of the most commonly used systems in the U.S.

Table 1:

Laser System What kind of eye tracker does it have? Does it have a closed-loop or open-loop system? Can it compensate for saccadic eye movements? What kind of laser beam does it have?
LADARVision® Laser radar Closed Yes Small spot
VISX Star* S2/S3 Video Open No Variable broad beam
B&L Technolas* 217 Video Open No Small spot
Nidek* EC-5000 N/A N/A No Scanning slit
LaserSight* LaserScan* LSX* N/A N/A No Small spot

All laser systems must be approved by the Food and Drug Administration (FDA) to treat specific vision problems. The following chart outlines current laser approvals; however, it does not list the specific treatment ranges. This information can be found on the section of the FDA's site on LASIK surgery.
