At these settings, tissue is uniformly ablated with minimal coagulative thermal changes to the underlying dermis. 38 Ross et al. investigated the effects of wiping after single and multiple-pass high energy pulsed CO2 laser surfacing in a pig model. The UltraPulse laser was used with pulse energy of 300 mj and a density setting of 5 using the CPG (fluence of 7J/cm2). Four different approaches were utilized: (i) one pass, no wipe; (ii) one pass, wipe after pass; (iii) three passes, no wiping between passes; and (iv) three passes, wiping after all passes.
