Flying Spot Laser Refractive Surgery

During any laser vision correction procedure, your eye moves in tiny ways called saccadic motions, an involuntary movement which is completely natural. These movements are impossible to either predict or prevent. This is where the skills of the eye surgeon have come into play in the past, training the laser beam as perfectly as possible on the area of the cornea to be corrected during refractive eye surgery.

The Flying Spot laser, which is officially called LADARVision for Laser Radar Vision, brings Star Wars technology from NASA's Strategic Defense Initiative era to address the problem in corrective eye surgery procedures. At our New Jersey and New York locations, Dr. Dello Russo has helped introduce the LADARVision technology to his patients.

In simple terms, the Flying Spot laser has the ability to track the tiniest eye movements and instantly retarget the beam to the correct spot on your cornea. Hence, "Flying Spot". This extremely precise refractive surgery innovation is available at both our New Jersey and New York locations.

The laser radar transmitted signal detects the location of the targeted spot for treatment and returns the information to the sensor 4000 times per second. Realignment of the mirror assembly to the eye's new position occurs in less than 10 milliseconds.

Also, this new laser is very tightly focused, a much narrower beam, which allows the most precise level of vision correction in ophthalmic history. Tiny differences in curvature leading to astigmatism, for example, can be deftly corrected by the Flying Spot laser of LADARVision during your corrective eye surgery procedure at our New Jersey and New York locations.

LADARVISION ACTIVE TRACKING occurs in "real time," using high-speed transmitted signals to constantly monitor the movements of the eye throughout corrective eye surgery procedures.

LADARVISION ACTIVE TRACKING is "robust" and an integral part of all procedures. To date, all refractive surgery procedures have been successfully completed with the tracker enabled.

How does LADARVISION ACTIVE TRACKING work?

The LADARVISION ACTIVE TRACKING SYSTEM consists of an infrared laser, position sensor, and adjusting tracker mirrors that are used during your refractive surgery at Dello Russo Laser Vision Centers in New Jersey and New York.

An infrared laser emits a beam, which reflects off adjusting tracker mirrors to the pupillary boundary. Light reflected off the pupillary boundary is detected by the position sensor, measuring the magnitude and direction of the eye's movement. The laser is then retargeted in less than 10 milliseconds, allowing highly precise re-sculpting of corneal tissue to achieve a smooth, blemish free surface that produces excellent vision and rapid healing.

Corrective Eye Surgery with LADARVISION ACTIVE TRACKING:

During surgery, the infrared laser beam automatically acquires and optimizes itself to the pupillary boundary of each individual patient, locking and coupling itself to the eye's saccadic movements (0.4 to 1.6 mm). The Infrared laser beam samples the eye's position 4,000 times per second, allowing the system to compensate for the eye's saccadic movements by realigning the adjusting tracking mirrors in less than 10 milliseconds.

Co-aligned with the tracker beam, the Excimer laser is simultaneously adjusted. LADARVision Active Tracking updates and realigns itself many times between each Excimer laser pulse fired, essentially "freezing" the saccadic and involuntary movements of the eye to ensure that patients experience exceptional corrective refractive eye surgery results at our New Jersey and New York locations.
