In people with defective vision, the light that falls into the eye is not focused sharply on the retina, so the image appears blurred. Glasses or contact lenses refract the light rays before they enter the eye and thus correct simple visual defects so that a sharp image is created. Although these vision aids are a blessing for people with impaired vision, they also have disadvantages.
Glasses fog up when the temperature changes, at work, outdoors, or when wearing face masks.
Contact lenses are often no longer tolerated after a few years or cause, among other things, the development of dry eyes and corneal infections, which can have serious consequences for patients.
For many people, seeing without glasses or contact lenses therefore means a new, more liberated life.
Since the end of the 19th century, ophthalmologists, physicists and engineers have been working intensively to develop surgical techniques to remove visual aids from impaired vision. These procedures are referred to as “refractive surgery.” Through continuous development, patient safety and also the accuracy of surgical techniques have been improved throughout their lives. The growing population of defective vision has made refractive surgery a popular area of modern medicine. Refractive procedures are among the most common operations performed on humans today and are also among the most efficient and safest.
The most common refractive procedures today are routine procedures with long-term experience of over 20 years. However, strict guidelines must be followed in order to keep the quality and safety of treatments as high as possible. As users of the KRC criteria, we are committed to respecting these guidelines to protect our patients.
