Abstract
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 (DED) 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 (NEI) 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 three months and six 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 ± 1.95 at three months (P = .001) and to −1.65 ± 2.42 at six months (P < .001). Conjunctival staining at six 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 ± 32.25 at the start of the study to 538.40 ± 31.36 after six 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 DED did not alter the measured variables of the corneal endothelium, but showed improvement in corneal staining and satisfaction.

Resumen
Objetivo

Evaluar los efectos y la seguridad del perfluorohexiloctano (F6H8) tópico en la superficie ocular y el endotelio corneal.

Métodos

Cuarenta y cinco pacientes (90 ojos) diagnosticados de Enfermedad de Ojo Seco (EOS) fueron reclutados y se les prescribió tratamiento con F6H8 durante seis meses. Las variables en la tinción corneal se documentaron usando la escala National Eye Institute/Industry Workshop (NEI), las variables conjuntivales usando la escala Oxford, y los parámetros corneales como el espesor corneal central, la densidad celular, el coeficiente de variación, la hexagonalidad y el área celular promedio, al inicio del estudio, a los tres meses y a los seis meses. Se evaluó también el cumplimiento y la satisfacción.

Resultados

el tratamiento con F6H8 redujo la tinción corneal promedio en pacientes cumplidores a una media de -0,84 ± 1,95 a los tres meses (p = 0,001) y a -1,65 ± 2,42 a los seis meses (p < 0,001). La tinción conjuntival a los seis meses mostró una disminución promedio de -0,13 (p = 0,319). Los parámetros endoteliales no mostraron diferencia significativa, excepto el espesor corneal central que mostró una disminución estadísticamente significativa (545,30 ± 32,25μm al comienzo del estudio y 538,40 ± 31,36μm tras seis meses, p = 0,009). Al final del estudio, el 46% de los pacientes informaron sentirse subjetivamente mejor, el 40,5% no sintió cambios y el 13,5% se sintió subjetivamente peor.

Conclusiones

El tratamiento tópico con F6H8 para EOS no alteró las variables medidas del endotelio corneal, mostrando mejoría en la tinción corneal y en la satisfacción.
