Adaptive Laser System for Ophthalmic Use


Executive Summary


It has become common to employ fast lasers for various forms of eye surgery. Aside from the technical benefits of using ultrafast lasers there were issues that arose. The formation of a bubble layer may occur along the cutting plane, which in some cases leads to an opaque bubble layer. These deeper bubbles may take a few hours to disappear, and if severe, may impair the aim of the eye tracker during surgery. There is interest in using shorter adaptive pulses to provide an overall reduction in the amount of energy per pulse required to cause a modification or cut in the tissue for a particular surgical procedure.


Description of Technology


Michigan State University has developed an adaptive laser system for ophthalmic use. The system uses laser pulses that are ten or more times shorter in duration than those conventionally used and employs temporal focusing of the laser beam pulse. The shorter pulses result in a ten-time reduction of average laser intensity used on the eye, making every procedure safer.  In this system a relatively inexpensive laser is employed. The system can create three-dimensional mapping of a portion of the eye in combination with automated feedback to assist with a surgical operation.


Key Benefits

  • laser pulses ten or more times shorter in duration than those conventionally used
  • temporal focusing of the laser beam pulse
  • safer



  • ophthalmic use to operate on an eye of a patient
