It is difficult to go through a day where you do not encounter a device that utilizes laser technology. The field ophthalmology is no exception. In fact, ophthalmologists use lasers more than any other medical profession. They are accurate, precise and predictable. The IH-YAG uses infrared laser light to treat the surface of the eye in a specific pattern, thus modifying its shape and how it focuses light.
Infrared light is invisible but is easily felt.
When you sit in front of a warm fire, it is the infrared light that warms you, not the light that you can see. Infrared lasers use this same heat to shrink tiny areas of collagen proteins in the cornea. Using specific spot sizes and patterns, LTK can change the corneal curvature, making it steeper and increasing its focusing power. The result allows the individual to see better at closer distances and even read without glasses. The current LTK procedures can be done right in the doctors office.
