If you intend to use an excimer laser, is it broadbeam, variable spot, or flying spot?
The type of laser beam may be very important or may mean very little, depending upon your individual circumstances. Depending upon your circumstances, only a flying spot laser would be appropriate or maybe any laser would do. The laser used is much less important than the doctor’s proven abilities. An inexperienced doctor with the fanciest equipment is worse than the best doctor with an older laser. All good doctors understand the limitations of their tools and techniques and will not perform surgery (no matter what the laser) if there is not a high probability of you receiving a good outcome.
