Description of Main Predictors for Taking Sick Leave Associated with Work-Related Eye Injuries in Spain.

Recent studies in Spain have shown that males, younger workers, and people involved in manual jobs had the highest risk of suffering a work-related eye injury (WREI). This study aims to assess the predictors of sick leave associated with WREI and to compare them with risk factors of initial injury. A retrospective and descriptive study of WREI that causes sick leave of one or more days among workers from an insurance labor mutual company in Spain was conducted over a period from 2008 to 2018. The variables of the study were sex, age, occupation, and type of injury. A total of 9352 (18.6% of 50,265 WREI) cases and 113,395 total days of sick leave were observed, with an estimated EUR 4,994,009.59 of associated labor cost. The main predictors of sick leave related to WREI were found to be female (highest incidence; 25.9 (95% CI (24.8-27.1))), >55 years of age (highest incidence; 20.5 (95% CI (19.3-21.7))), not working in the industry (lowest incidence; 13.8 (95% CI (13.3-14.2))), and not suffering "other disorders of conjunctiva" (lowest incidence; 5.7 (95% CI (4.7-6.8))). The consequences associated with WREI are worse for female and older workers, despite the main risk of suffering WREI being observed in males and younger workers.

Evolución de lesiones oculares en el trabajo en las comunidades autónomas españolas en el periodo 2008-2018 / Trends in work-related eye injuries in Spanish Autonomous Communities during 2008-2018

Objetivos: Analizar las diferencias en la evolución de las lesiones oculares en el trabajo entre las comunidades autónomas en España. Métodos: Se llevó a cabo un estudio descriptivo, retrospectivo y longitudinal de los accidentes laborales y las enfermedades profesionales de una Mutua Colaboradora de la Seguridad Social entre las diferentes comunidades autónomas españolas en el intervalo de tiempo de 2008-2018. Se analizaron aquellos accidentes que provocaron lesión en alguna estructura ocular, comparándose la incidencia por cada 100 000 asegurados y el riesgo relativo (RR) de sufrir una lesión ocular en el trabajo. Resultados: Se observó una disminución en la evolución de la incidencia de lesiones oculares en el trabajo en todas las comunidades, aunque con dos periodos diferenciados. El porcentaje de cambio anual disminuye en todas las comunidades hasta el 2013, pero entre 2013-2018 esta tendencia sólo se mantiene en Asturias, Castilla-La Mancha, Islas Canarias, Madrid, Murcia y Navarra. Castilla- La Mancha fue la comunidad autónoma con mayor incidencia (886.56/100 000) y riesgo relativo de sufrir una lesión ocular (RR 2.66; IC 95% 2.58 - 2.75), mientras Cataluña presentó la menor incidencia (82.25) y riesgo relativo (RR 0.25; IC 95 % 0.22 - 0.28). Conclusiones: Durante el periodo 2008-2018 se produce una disminución en la incidencia de lesiones oculares en el trabajo en todas las comunidades autónomas con un cambio de tendencia a partir del año 2013 (AU)

Objectives: To analyze the differences in work-related eye injury trends among the different Autonomous Communities in Spain. Methods: This was a descriptive, retrospective and longitudinal study based on a Social Security-affiliated mutual insurance company work injury and illness database for the period 2008-2018 that included all Spanish Autonomous Communities. Accidents that caused an injury to any ocular structure were analysed, and both the incidence of work-related eye-injuries per 100 000 insured workers and the relative risk of suffering an eye injury were compared. Results: We observed a general decrease in work-related eye injuries in all of the communities, although with two distinct time periods. The annual percentage change decrease occurred in all communities until 2013. From 2013 to 2018, however, this decreasing trend was only observed in Asturias, Castilla-La Mancha, Canary Islands, Madrid, Murcia and Navarra. Castilla-La Mancha was the Autonomous Community with the highest incidence (886.56/100.000), as well as the highest relative risk of suffering an eye injury (RR 2.66; IC 95% 2.58 - 2.75). At the other end, the lowest incidence (82.25/100.000) and RR (RR 0.247; IC 95 % 0.22 - 0.28) were observed in Catalonia. Conclusions: We observed a statistically significance decrease in the incidence and relative risk of work-related eye injuries in all Autonomous Communities over the study period, although this trend changed from 2013 onward (AU)

Weight of Different Intraocular Lenses: Evaluation of Toricity, Focality, Design, and Material.

PURPOSE: To evaluate the weight of intraocular lenses (IOLs) depending on their material, dioptric power, toricity, focality, and haptic design. METHODS: Twenty-eight different IOL models from nine different medical companies (a total of 38 IOLs) and 1 capsular tension ring (CTR) were evaluated. IOLs were weighed using a precision scale, in hydrated conditions, as an approximation to their intraocular status. RESULTS: Hydrophilic IOLs were heavier than hydrophobic lenses (p < 0.001). Regarding toricity, no statistical differences were found comparing toric to non-toric models (p=0.1). Likewise, no differences were found between multifocal IOLs and monofocal IOLs (p=0.19). Dioptric power did not affect IOL weight: IOLs of <15DP had similar weights to those of ≥15D and IOLs of ≥24D had similar weights to those of <24 D (p=0.86 and p=0.59, respectively). Plate-design IOLs were significantly heavier than 1-piece C-loop (p < 0.001), 3-piece C-loop (p < 0.001), and 4-haptic lenses (p=0.001). CONCLUSIONS: Of the characteristics analyzed that might influence IOL weight, lenses with hydrophilic material and plate-haptic design were found to be heavier. Toricity, focality, and dioptric power had no influence on IOL weight.

Description of the epidemiological characteristics of work-related eye injuries in Spain: a retrospective study.

OBJECTIVE: To describe the epidemiological characteristics and trends of work-related eye injuries (WREIs) in Spain over a 10-year period by sex, age and occupational sector. DESIGN AND SETTINGS: A descriptive, retrospective and longitudinal study based on data from workers insured by a labour insurance company in Spain from 2008 to 2018 was presented. The study considered the ratio of the number of WREI per 100 000 population and the relative risk of suffering an ocular injury. WREIs were characterised by sex, age and occupational sector of injured workers. PRIMARY AND SECONDARY OUTCOME MEASURES: Ratio of the number of WREI. PARTICIPANTS: In Spain, all workers are insured by a labour insurance company that provides cover in the event of work-related accidents. In this study, we have included all workers insured by one of these insurance companies, IBERMUTUA, with workers in all areas of Spain. RESULTS: The study included 50 265 WREI in the company over the 10-year period. Most of the injuries occurred in males (44 445; 88.4%), in 35-44 age group (15 992; 31.8%) and in industry workers (18 899; 42.6%). The average incidence was 429.75 per 100 000 workers insured and 4273.36 per 100 000 IBERMUTUA accidents (related and not related to eyes). Males, 16-24 age group and industry occupational sector group, have the highest incidence for WREI. The incidence of WREI decrease over the study period in all variables. Males have 6.56 (95% CI 6.38 to 6.75) times more risk of suffering WREI than females. 16-24 age group have 1.77 (95% CI 1.71 to 1.83) times more risk than in the group of workers older than 55. Finally, industry workers have 7.73 (95% CI 7.55 to 7.92) times more risk than services workers. CONCLUSIONS: The risks of suffering WREI is higher for males, younger and less experienced workers, and for those who works in a manual task.

Eye Injuries Epidemiology Description in a Working Population over 10 Years in Spain.

BACKGROUND: Several studies show a high percentage of eye injuries related to work compared to other origins. However, there are few studies that describe work-related eye injuries. METHODS: A descriptive, retrospective, and longitudinal study that describes the characteristics of work-related eye injuries in a group of insured workers. Eye injuries were classified according to the International Classification of Diseases (ICD-10) and analyzed over 10 years (2008-2018). RESULTS: Keratitis and conjunctivitis were the most prevalent injuries (26,674 (53.1%) and 15,906 (31.6%)). Keratitis and conjunctivitis also show the highest percentage of injury incidence per 100,000 insured workers in both sexes, any age group, and any occupation. The analysis of the cumulative percentage change and average annual percent change in incidences over ten years shows a decrease in the incidences of all injuries, except for other disorders of the eye and anexa. CONCLUSIONS: Most of the work-related eye injuries affect the most exposed eye structures in any line of work: the cornea and conjunctiva. Suitable protection of these eye structures will decrease the number of cases of work-related eye injuries.
