Operating theatres significantly contribute to hospital's environmental footprint, underscoring the need to evaluate the ecological impact of transporting surgical products. Intraocular lenses (IOLs), sourced globally, vary in their environmental impact due to differences in packaging and manufacturing. Assessing the carbon footprint of IOL transport and usage can promote sustainability.
A retrospective analysis of IOL stock data at Rothschild Foundation Hospital, Paris, was conducted to evaluate all IOLs implanted in 2023. To estimate the ecological footprint of IOL transport, the packaging weight of each model was measured, and the EcoTransIT online calculator was used.
In 2023, a total of 13,894 IOLs from 62 different models were implanted by 112 ophthalmic surgeons at our institution. Carbon dioxide (CO) emissions from the transport of IOL models varied from 1.05 to 12.72 kg per 1,000 units, influenced by packaging weight and shipping distances. Packaging volumes ranged from 135 to 917 cm³. Standard monofocal lenses comprised 65.9% of implanted IOLs, followed by monofocal "plus" lenses at 21.6%. Toric, non-toric extended depth of focus (EDOF), and non-toric multifocal lenses were used less frequently, at 7.4%, 3.9%, and 1.3%, respectively.
Significant disparities exist in CO emissions related to IOL distribution among different IOL models, highlighting the importance of minimising packaging to reduce environmental impact. Standard monofocal lenses remain the predominant choice among surgeons, with increasing adoption of monofocal "plus" lenses. Premium lenses are used sparingly. Optimising packaging could improve storage efficiency and logistics, potentially facilitating greater adoption of premium lenses, particularly toric lenses.
手术室对医院的环境足迹有重大影响，这凸显了评估手术用品运输的生态影响的必要性。全球采购的人工晶状体（IOL）由于包装和制造方面的差异，其环境影响各不相同。评估IOL运输和使用的碳足迹有助于促进可持续发展。
对巴黎罗斯柴尔德基金会医院的IOL库存数据进行回顾性分析，以评估2023年植入的所有IOL。为估算IOL运输的生态足迹，测量了每个型号的包装重量，并使用了EcoTransIT在线计算器。
2023年，我院112名眼科医生共植入了来自62种不同型号的13,894枚IOL。IOL型号运输产生的二氧化碳（CO）排放量每1000单位从1.05千克到12.72千克不等，受包装重量和运输距离影响。包装体积从135立方厘米到917立方厘米不等。标准单焦点镜片占植入IOL的65.9%，其次是单焦点“增强型”镜片，占21.6%。散光、非散光扩展焦深（EDOF）和非散光多焦点镜片的使用频率较低，分别为7.4%、3.9%和1.3%。
不同IOL型号在IOL配送相关的CO排放方面存在显著差异，凸显了尽量减少包装以降低环境影响的重要性。标准单焦点镜片仍然是外科医生的主要选择，单焦点“增强型”镜片的采用率在增加。高端镜片使用较少。优化包装可以提高存储效率和物流效率，有可能促进更多地采用高端镜片尤其是散光镜片。
