Laser effects in nonpigmented versus pigmented tissues using FiberTomeTM Nd:YAG and KTP

摘要

This study evaluated the effects of the FiberTome$+TM$/ (10, 20, 30 W), conventional Nd:YAG (10, 20, 30 W), and KTP (5, 10, 15 W) surgical laser systems, with respect to pigmented and nonpigmented tissues. The cutting width, cutting depth, and thermal damages were measured on the skin and liver of farmer pigs. The results show that there was no significant difference in the cutting width and depth, for nonpigmented versus pigmented tissues. KTP showed the most significant thermal damage reduction in pigmented tissue; 318 $mu@m in nonpigmented vs 94 $mu@m in pigmented tissue.
