Abstract
Rather than rely solely upon pupillary occlusion or tracking of eye movement to protect the fundus from accidental exposure to electromagnetic radiation, the present invention also utilizes an electromagnetic radiation pathway with a profile such that the energy density at the iris is greater than the energy density at the posterior portion of the eye. This disparity in energy density allows for efficacy at the anterior iris treatment site, without injury to the fundus.
Claims20
A method for preventing accidental overexposure of electromagnetic radiation to human eyes while applying electromagnetic radiation, the method comprising:
- determining a laser profile for a laser beam during a color changing operation, wherein the laser profile has a first energy density at an iris of a human eye and a second energy density at a posterior portion of the human eye, and wherein the first energy density is greater than a second energy density;
- generating, using an electromagnetic radiation generator, the laser beam based on the laser profile;
- and
- applying, using a computerized scanning system, the laser beam to a surface area of an anterior surface of the iris.
A non-transitory, computer-readable medium comprising instructions that, when executed by one or more processors, cause operations comprising:
- determining a laser profile for a laser beam during a color changing operation, wherein the laser profile has a first energy density at an iris of a human eye and a second energy density at a posterior portion of the human eye, and wherein the first energy density is greater than a second energy density;
- generating, using an electromagnetic radiation generator, the laser beam based on the laser profile;
- and
- applying, using a computerized scanning system, the laser beam to a surface area of an anterior surface of the iris.
