“…Con respecto a las características de la exposición a la que estuvieron sometidos el POE en este estudio, es decir, la emisión de radiación ionizante proporcionada por el equipo angiográfico utilizado en los procedimientos, se lograron condiciones experimentales acordes a las condiciones descritas en otros estudios 12,13 . Las lecturas realizadas se comportaron de distinta forma según el profesional evaluado.…”

“…El médico intervencionista se encuentra directamente protegido por un vidrio plomado, el cual atenúa la radiación secundaria proveniente del paciente; el arsenalero se encuentra ubicado cerca del médico, por lo que también recibe protección de este vidrio, protección que no es tan efectiva para el arsenalero pues, el médico es quien ubica este vidrio plomado en función de su protección, es así como en algunos momentos los haces de rayos-X primarios y secundarios logran impactar libremente y en forma oblicua el cerebro del arsenalero. Esto explicaría, posiblemente, por qué no se obtienen los resultados esperados considerando la distancia que existe desde la fuente o desde el paciente a cada estamento, en relación a resultados similares entregados por otro estudio 12 . Se debe tener en cuenta ciertas consideraciones 14,15 Figura 6.…”

“…Posiblemente, este fue un factor que pudo afectar los resultados de esta investigación, ya que se utilizó una equivalencia de Pb menor en el material radioprotector del gorro. Otro estudio que evaluó gafas plomadas, también obtuvo un bajo nivel de atenuación al emplear gafas con una equivalencia de Pb igual a 0,125 12 , en cambio los datos obtenidos por otros estudios 4,14 realizados con blindaje de grosor adecuado lograron alcanzar una mejor respuesta de protección.…”

“…In most of the early studies, dating back to the seventies and eighties, the x-ray stopping power of lenses not mounted in frames, both ordinary and specifically marketed as radioprotective, was estimated [8,10,12,13]. The more recent approach of directly testing these devices in the clinical practice [23,26,29,32,36,39,41] suffers from the drawback that it does not allow the measurement of the doses D and D pr in the correct position.…”

This paper attempts to systematise all published experimental results for the dose reduction factor (DRF) offered by leaded eyewear on clinicians performing interventional procedures. We aim to present a comprehensive analysis of the issue and a comparison of the various equipment models at different exposure geometries. The main purpose of the paper is, however, to clarify the best choice for the DRF within the possible diverse contexts and approaches to eye lens dose assessment. Evidence has been obtained that the lowest estimates of DRF are associated with larger scatter incidence angles and that, except for the slightly better performance exhibited by wraparound eyeglasses, there is no real distinction between the DRFs for the different equipment categories. The dataset as a whole confirms that, when measurements for the concerned eyewear model and irradiation conditions are unattainable, assuming DRF = 2 represents an adequately conservative choice. Nonetheless, this value includes only 17% of all results from the literature, whereas their histogram follows a distribution skewed towards higher values, represented by a median equal to 5. Therefore, if more realistic dose reconstructions are necessary, such as for purposes of epidemiological investigations or compensation decisions, the adoption of this central tendency index appears to be more reasonable. The complexity of characterising the DRF behaviour as a function of the various exposure factors reinforces the consideration of a statistical approach to eye lens dose assessment as a viable alternative. In this perspective, assuming for DRF a lognormal distribution with parameters and which has been verified to satisfactorily approximate the literature data distribution, should be deemed to be an appropriate option.

“…16 Zett-Lobos et al also explained that the use of protective eyewear with 0.25 mm Pb thickness reduced radiation scattering by 50%. 19 This can be achieved by good compliance and well position use of radiation protection equipment. 16 20 In this study, despite the compliance of radiation protection equipment usage was still not in accordance with national recommendation; however, it was relatively better than previous studies.…”

Purpose The aim of this study was to determine the prevalence of radiation-induced cataracts and its correlation with radiation exposure dose and radiation protection equipment use among radiation workers of interventional cardiology. Methods This is a cross-sectional and retrospective case–control study. We included 180 subjects. The prevalence of radiation-induced cataracts was assessed using Scheimpflug analysis on the Pentacam-Oculus device. Individual cumulative radiation exposure dose and radiation protection equipment use were identified from questionnaires and personal dosimeters. Results The prevalence of radiation-induced cataracts was 16.7%. The median cumulative radiation dose was 0.8 (0.1–35.6) Gy. A positive correlation was found between cumulative radiation dose and lens density (R Spearman = 0.64). We found 83.9% of subjects used ceiling-suspended shields in 71 to 100% of their working period. However, most subjects (40.6%) did not wear protective eyewear. There was a statistically significant increasing risk of radiation-induced cataracts and unresponsive use of radiation protection equipment. Subjects using ceiling-suspended shield in only 31 to 50% of their working period increased their cataract risk by 10.8 times (95% confidence interval [CI]: 1.05–111.49, p = 0.044). Meanwhile, subjects using protective eyewear in only 51 to 70% of their working period increased their cataract risk by 8.64 times (p = 0.001). Subjects who did not wear protective eyewear had an odd ratio of 164.3 (95% CI: 19.81–1363) compared to those who did. Conclusion Radiation-induced cataracts among radiation workers of interventional cardiology depended on the radiation exposure dose and the use of radiation protection equipment.
