Lasers (Light Amplification by Stimulated Emission of Radiation) have been developed to focus light of specific wavelength into very narrow and controlled beams of light. Lasers have been used for the benefit of all or us in a number of different kinds of applications. Many of these applications are in the medical field. Several lasers have been developed specifically for use in eye surgery. The surgeons of Maryland Eye Associates use several different lasers to perform a variety of procedures to treat medical and structural problems with the eye. Maryland Eye Associates has the latest, state of the art laser surgical instruments available for treatment including the YAG laser, the Diode laser, the Pulsed Diode laser, and the lasers used for refractive surgery. Laser surgery can be performed with a minimum of discomfort to the patient.
