Not every laser system is indicated, or approved by the FDA, to treat every type of vision problem. Ask your doctor which technologies are used. Most importantly, you should confirm with your doctor that the laser system used in your procedure can correct your specific eye problems. You should also compare laser systems to learn other important aspects of their capabilities.

LADARVISION
The LADARVISION® Difference
 No two eyes are exactly alike. That's why Alcon Surgical developed LADARVision® - an advanced Excimer laser system designed to give each patient the best possible result. LADARVision® is distinctively different from all other Excimer laser systems. It combines the only patented laser radar eye tracker, the LADARTrackerTM, with a unique small spot laser beam. These features were designed to increase the accuracy of corneal shaping.
Our eyes are constantly making small, rapid movements that are beyond our control. Computer simulations have shown that eye movement during LASIK can compromise laser beam placement accuracy. This can cause irregularities in the corneal surface, introducing new refractive errors and resulting in sub-optimal visual acuity.
The LADARTrackerTM accurately tracks eye movements during surgery so you do not have to worry about holding your eye still. The tracker adjusts and realigns itself between each laser pulse, tracking the position of your eye 4,000 times per second, guiding placement of the laser beam with pinpoint accuracy.
Guided by the active eye tracker, the LADARVision small spot laser beam (less than 1 mm wide), reshapes the cornea, removing corneal tissue smaller than the width of a single human hair. This combination offers our patients state-of-the-art Excimer laser technology.
The LADARVision® system
There are a number of factors that will affect both your actual laser vision correction procedure and the results you can realistically expect to gain from it. Among them are:
- Your existing vision problems, and the amount of correction that can be achieved
- The experience and expertise of the physician attending you
- The technology behind the laser eye surgery system your physician will use
- The first two factors may seem self-evident, but the third may come as some surprise. This is understandable since many people are unaware that different laser systems with different capabilities are available. Technology matters because it can impact the accuracy with which your cornea is reshaped and therefore the results you can expect from the procedure.
Is LADARVision® the Right System for Your Vision Problem?
 Not every laser system is indicated, or approved by the FDA, to treat every type of vision problem. That's why, when choosing your doctor, it's important to know if the laser system that will be used in your procedure is actually approved to correct your specific eye problems. You can find out by comparing systems to learn about their FDA indications and other important aspects of their capabilities.
If you choose a doctor equipped with the LADARVision® System, you'll have the comfort of knowing that your doctor's system is approved for the widest possible range of problems from myopia to hyperopia, with or without astigmatism, and is approved to correct mixed astigmatism. In October 2002, CustomCornea® was the first to be FDA approved for the treatment of higher order aberrations that can affect the quality of your vision.
