Abstract

Objective: To determine the effectiveness of picosecond KTP in reducing peri-ocular dark circles caused mainly by excessive pigmentation and to compare Picosecond KTP with Thulium laser ability in reducing the intensity and extent of peri-ocular dark circles.

Materials and methods: This split-face prospective study included twelve women with periorbital dark circles (pigmented or mixed-pigmented type). The left lower eyelid was treated using the PicoHi machine (HIRONIC Ltd), a full beam Q-switched Nd-YAG provided by KTP crystal (523 nm) at settings of 0.3 J/cm², 5 mm, 5 Hz, and 300 Ps. Whereas the right lower eyelid was treated using the Lavieen machine (WON TECH Co., Ltd), a fractional Thulium laser (1927 nm) at setting 1320 mJ/cm², 30 × 15 mm, 1500 microseconds. Patients received a series of 3 treatment sessions, given at 4-week intervals.

Results: The 532-nm full beam Q-switched KTP and fractional Thulium lasers were more likely to induce post-inflammatory hyperpigmentation rather than decrease the pigmentation. The risk is higher with a Q-switched KTP laser, which may be attributed to the skin tone of the participants. Nonetheless, some improvement in the pigmented type of PDCs, although not detected clinically, was documented by the VISIA software.

Conclusion: No solid conclusion can be drawn from the results of the study. Picosecond KTP and Thulium lasers may have a role in reducing PDCs yet more studies should be performed in order to determine the exact impact these lasers have.

评估皮秒 KTP 激光和点阵铥激光对色素型眶周黑眼圈的疗效。

目的确定皮秒 KTP 在减轻主要由过度色素沉着引起的眼周黑眼圈方面的有效性，并比较皮秒 KTP 和铥激光在减轻眼周黑眼圈的强度和范围方面的能力：这项分面前瞻性研究包括12名患有眼周黑眼圈（色素型或混合色素型）的女性。使用 PicoHi 仪器（HIRONIC 有限公司）治疗左下眼睑，该仪器是由 KTP 晶体（523 nm）提供的全束 Q 开关 Nd-YAG，设置为 0.3 J/cm2、5 mm、5 Hz 和 300 Ps。右下眼睑则使用 Lavieen 仪器（WON TECH 有限公司）进行治疗，这是一种点阵式铥激光器（1927 纳米），设置为 1320 毫焦/平方厘米、30 × 15 毫米、1500 微秒。患者共接受了 3 次治疗，每次间隔 4 周：结果：532 nm 全光束 Q 开关 KTP 激光器和点阵铥激光器更容易诱发炎症后色素沉着，而不是减少色素沉着。调Q开关KTP激光的风险更高，这可能与参与者的肤色有关。尽管如此，VISIA 软件还是记录了 PDC 色素类型的一些改善，尽管临床上并未检测到：结论：从研究结果中无法得出可靠的结论。皮秒 KTP 激光器和铥激光器可能对减少 PDC 有一定作用，但要确定这些激光器的确切影响，还需要进行更多的研究。

期刊介绍： Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics. The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
