The Excimer Laser is one of the greatest inventions in ophthalmology. The Excimer Laser is the device that physically corrects your prescription during surgery. Because laser vision correction is based on the microscopic removal of corneal tissue at the molecular level it is impossible to achieve this type of accuracy manually. No other device has provided patients the opportunity to reduce or eliminate their dependency on glasses and contacts. Although many people perceive laser technology to be the same, there are vast differences between one laser versus another. One question that should be raised prior to your surgery is whether the laser being used is the newest in laser vision correction technology. By having your eyes treated with the newest in laser vision technology it increases your chances for a successful outcome.
