>Application of Electromagnetic Radiation to the Human Iris
>In the case of laser energy, the specific gain media may comprise Nd:YAG, alexandrite, pulsed-dye, or any other medium

>Another candidate is the PhotoGenica V-Star Pulsed Dye Laser (Cynosure, Inc., Chelmsford, Mass., USA), with wavelength of 585 nanometers
>According to one embodiment of the present invention, there is provided a method for altering iris pigment in a human or animal, thereby altering iris color of a first iris from a first iris color to a second iris color

>Iris pigment can be removed in a variety of ways [...] In addition a laser could simply shut off the melanin without killing or bursting the pigmented cells. In this case, no elimination would be required. Moreover, it is possible to shut off one melanin pigment (such as, eumalanin) without shutting off another (such as, pheomelanin), thereby further influencing the modified color of the iris

>Evaluation of Color-Changing Effect and Complications After Nd: YAG Laser Application On Iris Surface
>The laser was applied in 3 sessions at 2-week intervals, at energy levels of 0.8 mJ in Group A and 1.5 mJ in Group B
>reduction in pigment density was more profound in Group B compared to Group A, which was statistically significant (p<0.019)
>In this study, a device that produces frequency doubled, 532 nm wavelength Nd: YAG laser with 900 μm spot diameter (A.R.C. Laser, Germany) was used
