    Objetivo Evaluar los efectos y la seguridad del perfluorohexiloctano (F6H8) t贸pico en la superficie ocular y el endotelio corneal. M茅todos Fueron diagnosticados 45 pacientes (90 ojos) de enfermedad de ojo seco, se seleccionaron y se les prescribi贸 tratamiento con F6H8 durante 6 meses. Las variables en la tinci贸n corneal se documentaron usando la escala National Eye Institute/Industry Workshop (NEI), las variables conjuntivales usando la escala Oxford y los par谩metros corneales, como el espesor corneal central, la densidad celular, el coeficiente de variaci贸n, la hexagonalidad y el 谩rea celular promedio, al inicio del estudio, a los 3 meses y a los 6 meses. Se evalu贸 tambi茅n el cumplimiento y la satisfacci贸n. Resultados El tratamiento con F6H8 redujo la tinci贸n corneal promedio en pacientes cumplidores a una media de -0, 84 卤 1, 95 a los 3 meses (p = 0, 001) y a -1, 65 卤 2, 42 a los 6 meses (p < 0, 001). La tinci贸n conjuntival a los 6 meses mostr贸 una disminuci贸n promedio de -0, 13 (p = 0, 319). Los par谩metros endoteliales no mostraron diferencia significativa, excepto el espesor corneal central, que mostr贸 una disminuci贸n estad铆sticamente significativa (era de 545, 30 卤 32, 25 碌m al comienzo del estudio y 538, 40 卤 31, 36 碌m tras 6 meses, p = 0, 009). Al final del estudio, el 46% de los pacientes informaron sentirse subjetivamente mejor, el 40, 5% no sinti贸 cambios y el 13, 5% se sinti贸 subjetivamente peor. Conclusiones El tratamiento t贸pico con F6H8 para la enfermedad de ojo seco no alter贸 las variables medidas del endotelio corneal, aunque s铆 mostr贸 mejor铆a en la tinci贸n corneal y en la satisfacci贸n. Objective: To evaluate the effects and safety of topical drops of perfluorohexyloctane (F6H8) on the ocular surface and the corneal endothelium. Methods: Forty-five patients (90 eyes) diagnosed with dry eye disease were recruited and prescribed treatment with F6H8 as part of a six-month prospective multicentre study. Variables in corneal staining were documented using the National Eye Institute/Industry Workshop scale. The conjunctival variables included using the Oxford scale, as well as corneal parameters, such as central corneal thickness, cell density, coefficient of variation, hexagonality, and mean cell area, at the start of the study, and at 3 months and 6 months. Compliance and satisfaction with the treatment were measured. Results: F6H8 drops reduced mean corneal staining based on the NEI scale in compliant patients to a mean of -0.84 卤 1.95 at 3 months (P=.001) and to -1.65 卤 2.42 at 6 months (P<.001). Conjunctival staining at 6 months showed a mean decrease of -0.13 (P=.319). The endothelial parameters did not show a significant difference, in contrast to the central corneal thickness that showed a statistically significant decrease (545.30 卤 32.25 at the start of the study to 538.40 卤 31.36 after 6 months, P=.009). At the end of the study, 46% of patients reported feeling subjectively better, 40.5% felt the same, and 13.5% felt subjectively worse. Conclusions: Topical treatment with F6H8 for dried eye disease did not alter the measured variables of the corneal endothelium, but showed improvement in corneal staining and satisfaction
