Here's a dirty secret: "robotic" and "laser" surgery are generally marketing ploys more than anything.
Sure, there may be some benefits but their are also compromises. EVERYTHING in medicine has a down side.
Have the laser surgery if you like but make sure you know why it's better than the conventional surgery or what you expect to gain over conventional surgery.
A good answer may simply be that you like your surgeon and he prefers or is more proficient w/ laser surgery.
Bad decisions make good stories.
