Lasers parameters for Nd:YAG laser iridotomy

Power1-6 mJ
Spot size50-70 μm (constant for each laser model)
Pulses per burst1-3
RecommendationsSet defocus to zero Focus the beam within the iris stroma rather than on the surface of the iris* Avoid any apparent iris vessels Use the least amount of energy that is effective139 Lens capsule damage is possible above 2 mJ energy With most Lasers less than 5 mJ per pulse is required
