CustomCornea (LADARVISION)

Dr. Walter Fried utilizes the LADARVision, Custom Cornea Laser, the first approved, tracker-guided, small spot laser system. LADARVision combines active tracking and small beam corneal shaping, two features previously unavailable in the United States.

From inception, Autonomous, the company that created LADARVision has been dedicated to a distinctively different technology that integrates a guided system where each laser pulse is carefully placed to reshape the cornea of the eye. The built-in eye tracker will automatically follow any eye movements during your surgery. LADARVision was born from laser radar technology, which simultaneously transmits and reacts to a signal in real time. Before you join the millions of people around the world who now see more clearly through laser vision correction, it is important to understand LADARVision and how it works to correct vision.

The expertise in the critical areas of eye tracking had its genesis in many years of contract research and development for the Strategic Defense Initiative and the National Aeronautic and Space Administration (NASA). More than $35 million dollars has been invested by industry to develop this technology and its application to an excimer laser to correct vision beyond the original government research.

The LADARTRACKER takes the worry out of moving your eyes during surgery. Please CLICK HERE to watch an interactive demonstration about Ladarvision.

LADARVision is distinctly different from all other systems available and represents the future of Laser Vision Correction today! It combines the first laser radar eye tracker with unique, small spot shaping laser pulse delivery.

Our eyes are constantly making small, rapid movements that are beyond our control. Computer simulations have shown that these movements during surgery can affect placement of the laser beam, increasing corneal irregularities. This in turn, can cause decreased visual acuity.

Now, you don’t have to worry about moving your eyes during surgery. The LADARTRACKER patented active eye tracker improves the accuracy of corneal shaping by:

• Accurately tracking eye movement 4,000 times per second during surgery.
• Adjusting and realigning itself between each laser pulse.
• Guiding the placement of the laser beam with pinpoint accuracy.

In standard laser vision treatments, the refraction of the eye is measured in the doctor’s office and the first two aberrations of the eye, sphere and cylinder are determined. These numbers are then typed into the laser, which then reshapes the cornea with them. Most standard lasers actually increase the third aberration, called spherical aberration, although there is one standard laser that does not. Spherical aberration, not pupil size, is the culprit in most cases of night-time glare after laser vision correction surgery.

The LADARVision Custom Cornea System measures the first 20 or so aberrations and attempts to minimize all of them. While it is not possible to get them all to zero, the improvement usually makes vision after surgery better than before surgery at night and under poor lighting conditions.

We can use the Custom Cornea system with LASIK, LASEK or PRK.
