Objective: To retrospectively evaluate the efficacy of an Alexandrite picosecond laser versus Nd:YAG nanosecond laser for removing blue–black eyeliner tattoos which have existed more than 10 years.

Methods: A total of 40 patients were treated with an Alexandrite picosecond laser in our department from August 2015 to July 2017, with a fluence of 1.96–6.37J/cm2, sp ot size of 2.0–3.6 mm, and pulse width of 750 ps. Another 32 patients were treated with an Nd:YAG nanosecond laser, with a fluence of 2.80–7.00 J/cm2, spot size of 3 mm, and pulse width of 5–20 ns. All analysed patients completed at least one treatment and follow-up.

Results: The median number of treatment for all the patients was 1 (range, 1–4). After a single session, no difference was found between the two lasers for the eyeliner removal (p > 0.05). For the people who achieved an excellent response of tattoo clearance, there was still no difference between the two groups (p > 0.05). Transient side effects were observed in two groups, but neither group had significant adverse reactions.

Conclusions: To treat blue–black Chinese eyeliner tattoos over 10 years, Alexandrite picosecond laser does not provide better clearance than the Nd:YAG nanosecond laser.

目的：回顾性评价紫翠宝石皮秒激光与Nd：YAG纳秒激光去除存在10年以上蓝黑眼线纹身的疗效。

方法：自2015年8月至2017年7月，采用紫翠宝石皮秒激光治疗40例患者，激光能量1.96~6.37J/cm2，光斑大小2.0~3.6 mm，脉宽750ps。另32例采用Nd：YAG纳秒激光治疗，激光能量2.80~7.00J/cm2，光斑大小3 mm，脉宽5~20 ns。所有被分析的患者都至少完成了一次治疗和随访。

结果：所有患者治疗次数中位数为1次(范围1~4次)。单次治疗后，两种激光去除眼线的效果差异无统计学意义(p>0.05)。对纹身清除效果好的患者，两组差异无统计学意义(P>0.05)。两组均观察到一过性副作用，但均未见明显不良反应。

结论：紫翠宝石皮秒激光治疗10年以上蓝黑色中国人眼线纹身的清晰度并不比Nd：YAG纳秒激光好。
