I wonder how many of us do this for patients. I tried it twice with minimal success. No matter how much I shoot at it, it just kinda sits there. I am afraid to ramp up the power, lest I cause a shock wave that could create a tear. I also wonder how likely that complication is, anyway. I remember reading an article in the throwaways by a surgeon who does hundreds of these lasers, and he claimed great success with no complications, but he was also selling a special lens for this purpose, so I worry about bias.
