ABSTRACT

OBJECTIVE: To evaluate the efficacy of the topical use of periocular and conjunctival povidone-iodine solution applied the day before cataract surgery to reduce conjunctival flora. PATIENTS AND METHODS: Randomized and prospective clinical trial with 82 patients. The treatment group (41 patients) received an application of topical 10% povidone-iodine solution on the periocular skin and instillation of topical 5% povidone-iodine solution on the forniceal conjunctiva the day before and one hour before surgery. The control group (41 patients) only received the usual perioperative disinfectant. Conjunctival smears were obtained from in all patients at the end of the surgery and these were sent to the Microbiology Laboratory for culture. RESULTS: In the treatment group 1 positive culture was found in the 41 eyes (2.4%). In the control group, there were positive cultures in 6 out of 41 eyes (14.6%). The difference is statistically significant (p<0.05). CONCLUSIONS: The disinfecting of the periocular skin with 10% povidone-iodine solution and of the conjunctiva with 5% povidone-iodine solution the day before and one hour before cataract surgery is effective in reducing conjunctival bacterial colonization compared with perioperative disinfection alone.

ABSTRACT

Objetivo: Valorar la eficacia de la aplicación tópica de povidona yodada periocular y conjuntival administrada el día previo a la cirugía de catarata para reducir la flora conjuntival. Pacientes y métodos: Estudio prospectivo y aleatorio con 82 pacientes. En el grupo de casos (41 pacientes) se aplicó una solución de povidona yodada al 10 por ciento periocular y al 5 por ciento instilada en fondos de saco conjuntivales, el día previo y una hora antes de la cirugía. En el grupo control (41 pacientes) se realizó solamente la desinfección peroperatoria. Se tomaron frotis conjuntivales de todos los pacientes al finalizar la cirugía, enviándolos al Laboratorio de Microbiología. Resultados: En el grupo de casos se encontró cultivo positivo en 1 de 41 ojos (2,4 por ciento), mientras que en el grupo control se aislaron cultivos positivos en 6 de 41 ojos (14,6 por ciento). La diferencia es estadísticamente significativa (p<0,05). Conclusión: La desinfección de la piel periocular con povidona yodada al 10 por ciento y la instilación conjuntival de la misma solución al 5 por ciento el día previo y una hora antes de la cirugía de catarata se ha mostrado eficaz para disminuir la colonización bacteriana conjuntival en comparación con la desinfección peroperatoria aislada.
