A number of lasers are available for cutaneous periorbital surgery, yet not all eye shields are appropriate for all applications. We tested a variety of commercially available eye shields to assess their safety features.
STUDY DESIGN/MATERIALS AND METHODS: Six commercially available eye protectors were studied. A focused laser was incident upon the shield, and the intensity and exposure duration required for visible damage to the shield were measured. We then measured the temperature on the underside of the eye shield during exposure from the laser. Time-dependent temperature measurements were made with a type-T thermocouple fixed to the eye shield with silicon grease.
Thermal response curves and rates of warming for each of the six eye shields were generated. Plastic shields showed significant thermal damage with most of the lasers tested. The metallic shields warmed more slowly and to a lesser degree.
Overall, the metallic eye shields had the most acceptable safety profile. Many of the plastic shields exhibited significant thermal damage, and therefore we discourage their use in periorbital laser surgery.
有多种激光可用于眶周皮肤手术，但并非所有的眼罩都适用于所有的手术。我们测试了多种市售眼罩以评估其安全特性。
研究设计/材料与方法：研究了六种市售的眼部保护器。将聚焦激光照射到眼罩上，测量使眼罩出现可见损伤所需的强度和暴露持续时间。然后在激光照射期间测量眼罩下侧的温度。使用用硅脂固定在眼罩上的T型热电偶进行随时间变化的温度测量。
生成了六种眼罩各自的热响应曲线和升温速率。对于大多数测试的激光，塑料眼罩显示出明显的热损伤。金属眼罩升温更慢且程度更小。
总体而言，金属眼罩具有最可接受的安全特性。许多塑料眼罩表现出明显的热损伤，因此我们不建议在眶周激光手术中使用它们。
