Pulsed lasers remove the worry of damaging surrounding tissue. An individual pulse of light lasting 5 billionths of a second will remove only 0.2 microns of eye tissue. This is just one hundredth of the diameter of a typical cell. This type of precise tissue removal can be used to sculpt eye tissue alleviating the common sight problem of near-sightedness.

A similar technique will remove electrons from molecules, leaving behind a collection of charged particles known as a plasma. This plasma can absorb laser energy and become larger, creating a shock-wave that disrupts the material around it. This technique is used to remove cataracts from the eye.
