WaveLight lasers Technology

The health of your eyes is critical and their safety a fundamental requirement. Therefore, WaveLight lasers come with a unique safety feature: PerfectPulse Technology ™. This sophisticated technology ensures that the entire treatment and each pulse of the laser beam are completely controlled.
PerfectPulse Technology ™
* High precision process control
* Eliminates environmental factors like humidity and temperature with a sealed enclosure for the optics
* Ensures placement of every laser pulse with ultra-fast eye tracking that follows the fastest eye movements precisely with the laser beam. So, even when your eye moves, the treatment remains perfectly centered
* Prevents thermal effects on the eye and dryness, improving the healing process
In order to provide the most precise results, physicians conduct an accurate assessment of the eye’s visual defects and exactly determine its health. The WaveLight laser then uses this information to create a precise treatment with an accurate and predictable outcome.
The WaveLight laser uses a very small laser beam that shapes the eye’s surface like a very delicate brush. The smooth shape of the beam creates an even surface across the entire eye, once again shortening healing times and providing precise results.
With the WaveLight laser systems the actual treatment time lasts only a few seconds as compared to often longer procedures. An average treatment will take no more than 10-12 seconds – in many cases even less.
This faster treatment reduces the risk of infection because it minimizes the eye's exposure to surrounding air. Also, clinical studies demonstrate that a quick treatment will reduce the healing and recovery time since the stress impact on the eye is lessened and dehydration is reduced.
Focus on Life
Our eyes are our windows to the world. Outstanding eyesight enables us to perceive our surroundings and experience life to its fullest. Of all the senses, sight is most important.
Vision problems directly impact our quality of life whether we try to read a blurry alarm clock each morning or must wear contact lenses. Refractive surgery can eliminate these problems and provide us with better vision, freeing us to enjoy a more energetic and active lifestyle.

The Human Eye
In a normal-sighted human eye, incoming rays of light travel through the cornea and the lens before forming a sharp focus point on the retina. Neural receptors then translate the incoming signals into electronic impulses and transmit them through the visual nerve to the brain. The brain then translates these impulses into an image that we interpret as vision. In this way, our eye acts similar to a photo camera with the image being developed in our brain.

Visual Defects (Ametropia)
In a normal-sighted (emmetropic) eye, the cornea and lens are exactly matched to the length of the eye. In many eyes however, this is not the case and the focus point of incoming rays of light is no longer on the retina.
Nearsightedness (myopia)

The eye is nearsighted if we are unable to see distant objects clearly. In the case of myopia the eye is too long, so that rays of light intersect in front of the retina. This results in blurred images.
Farsightedness (hyperopia)
Farsighted people have trouble seeing close objects or performing close-up activities such as reading. Their eyes are too short so that the rays of light actually intersect behind the retina. As a result, near objects cannot be seen clearly.
Nearsighted and farsighted eyes can also have an astigmatism. In this case the shape of the cornea is not perfectly round, but rather like a football. Rays of light are, therefore, bent in different directions and do not form a sharp focus point anymore. As a result, images appear distorted.
In addition, many people suffer from age related farsightedness (presbyopia) as they get older and require reading glasses or bifocal lenses. This problem occurs because the natural lens in the eye slowly stiffens as it matures and thus loses its ability to accommodate. Presbyopia is not caused by a change in eye length. Therefore, a laser treatment can only provide limited help. If your eyes are presbyopic, ask your physician about possible treatments that can improve your sight.

A Proven Treatment

Refractive surgery has been used globally since the 1970s. In 1987, refractive laser surgery opened up entirely new possibilities for the correction of visual problems. Initially, laser surgery was conducted using the PRK (photo refractive keratotomy) method. Since the early 1990s, however, LASIK (laser in situ keratomileusis) has become the treatment of choice around the world. Laser surgery has been evaluated and studied in numerous clinical studies involving thousands of patients by several independent regulatory bodies, such as the U.S. Food and Drug Administration (FDA). Today, millions of people already enjoy independence from glasses and contact lenses, and an improved quality of life, thanks to refractive laser surgery.
The Laser Treatment
Before the treatment, your physician will conduct a detailed examination to determine if your eyes are healthy and suitable for laser surgery. If you wear contact lenses, you should stop wearing them at least two to six weeks before the actual treatment, depending on the type of contact lens that you are wearing.
Your physician will conduct an extensive examination of your eye before the laser treatment in order to precisely determine its health, corneal thickness, and the degree of your visual defect. Once the examination is completed on the day of treatment, you will lie down on the laser bed. The physician will then apply eye drops to numb your eye.
In the first step of the procedure, the physician creates a thin flap in the upper layer of your cornea. During this time your sight will be briefly interrupted due to increased ocular pressure in your eye. Then the flap is carefully folded back to expose the lower corneal layer. At this point you will be able to see, but everything will be blurry.
For the next step, the physician will ask you to concentrate your sight on a green light. Then the actual laser treatment begins. Due to the high speed of the laser system, the average treatment will only take a few seconds.
Once the laser treatment is finished, the flap is returned to its original position where it completely adheres and works like a natural band-aid. Your eye will then receive antibiotic eye drops to prevent infections. The treatment is now fully completed.
You will already be able to see your surroundings with improved visual acuity, but your eye may itch or burn and you may experience sensitivity to light. You should try to rest and avoid strenuous visual activities like reading or watching TV during the next few hours while your eye continues to heal.

Quality of Vision
Today, patients want to see better than they can with their glasses and contact lenses. They want to improve their quality of vision, especially at night and with regards to depth perception and contrast sensitivity.
The WaveLight laser was engineered to consider the natural shape of the human eye. It aims to improve what nature originally designed. Its treatment considers the unique curvature and biomechanics of each eye, preserving quality of vision.

Superior results
In order to receive permission from the Food and Drug Administration (FDA) to treat patients in the United States, WaveLight was required to conduct a strictly controlled clinical study on more than 1,200 myopic and hyperopic eyes and then monitor and report the results over a one-year period following the treatments.
The outcomes not only fulfilled the rigid standards of the American regulatory authorities, they exceeded them. Thus WaveLight effectively demonstrated the precision and stability of its laser.

After years of clinical and technical research, the time has come to consider laser vision correction as a proven and safe alternative to glasses and contact lenses. Millions of people around the world already enjoy an improved quality of sight and quality of life.

Important Considerations
Refractive eye surgery is a medical procedure. Therefore, it is important to understand that there are certain risks associated with such a treatment. Before making your decision you should carefully weigh the risks and benefits.
Your doctor will answer all your questions honestly and in detail. All safety and risk information specific to the equipment and methods being used in the clinic will be disclosed to you.
During the consultation, make sure to advise your doctor of all medications you are taking, any injuries that ever occurred to your eye, and provide a detailed medical history. Only then can your physician make a safe decision about your ability to have a refractive laser treatment.
