The excimer laser used in laser vision correction is probably very different from what you think a ‘laser’ would normally be.
When recontouring the tissue of the cornea, the excimer laser does not burn tissue as one would think a laser might. Instead, the laser causes changes at the cellular level, and cells simply lift away. Because this laser does not damage surrounding cells, the excimer laser is ideal for surgeries on sensitive organs of the body – particularly the eye. This remarkable laser essentially sculpts the eye to the ideal shape without relying on surgeon skill.
