Eye Laser Procedures - Zimm Cataract & Laser Center in Erie, PA

The development of lasers and their use in medicine has revolutionized the way many eye diseases are treated. With lasers, sight loss can be stabilized more effectively and safely than ever before, as well as reducing the time, cost, and complexity of many procedures. In some cases, this sight-saving tool can also be used to restore previously lost vision.

Laser light is not radiation, like x-rays, cosmic rays, or gamma rays. It is made of a single color or wavelength of light with all of the light rays traveling in the same direction.

When this coherent light is released, it passes through a system of lenses that concentrate the energy to an extremely fine point.

The light itself is safe and does not become effective in medical treatment until it becomes highly concentrated through the use of special mirrors and lenses.

Laser light reaches its maximum strength at the focal (strong) point - the point where all the rays converge. Once the light passes the focal point, the strength of the beam is rapidly diminished.
