the importance of laser technology

All laser vision correction systems use a laser beam to reshape the cornea and correct vision problems. But that's where the similarities end. The laser technology (or wavefront technology) on which different vision correction systems are based varies considerably. You should choose the system best suited to correct your individual vision problems, and you want the system that delivers the most accurate vision possible.

Alcon's LADARVision® System lets your doctor create a laser vision correction treatment that is customized for each of your eye's optical characteristics. This is Alcon's CustomCornea® difference.

Advances in Laser Technology

Since refractive surgery was first performed, there have been great strides in technology. Early refractive surgery was called Radial Keratotomy (RK), and the cornea was reshaped with a scalpel. Now, with the introduction of LASIK, a computer-controlled excimer laser is the reshaping device of choice.

In the early days of refractive surgery, only nearsightedness could be corrected. Later technological advances added the ability to correct farsightedness as well as astigmatism.

Now, with the introduction of Alcon's CustomCornea® your doctor can correct an even wider range of visual difficulties, including those previously undetectable. These problems are called higher order aberrations, and many experts believe these may be partially responsible for low-light vision problems, such as halos and glare.

Accordingly, the result of your laser eye surgery depends on your choice of laser technology, along with your doctor's skill and experience.

Choose the Right Laser Technology for You

Not every laser system is indicated, or approved by the FDA, to treat every type of vision problem. When choosing your doctor, ask 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.

While the laser technology used in a vision correction system is an important factor when choosing a procedure, it's not the only factor. In addition, there are many other considerations to take into account when making your decision about laser eye surgery.
