The Preventive Effect of Gentamicin in the Irrigating Solution on Endophthalmitis Caused by Methicillin-Resistant Staphylococcus epidermidis After Phacoemulsification with Intraocular Lens Implantation in Rabbits.

To analyze the effect of gentamicin in the irrigating solution on endophthalmitis caused by methicillin-resistant Staphylococcus epidermidis after phacoemulsification with intraocular lens implantation. Fifteen rabbits were randomly assigned into three groups. During surgery, group A was irrigated with gentamicin-free solution and injected with 100 μL of normal saline postoperatively, group B was irrigated with 80 μg/mL gentamicin and injected with 100 μl of MRSE suspension, group C was irrigated with gentamicin-free solution and injected with 100 μl of MRSE suspension. At different times, corneal endothelial cell count (CEC), inflammation grading，B-scan ultrasonography and histological examination were analyzed. No endophthalmitis occurred in groups A and B. Group C developed severe endophthalmitis, with massive inflammatory exudation in the vitreous cavity. Irrigating solution containing gentamicin is favorable to reduce the incidence of MRSE endophthalmitis after phacoemulsification with IOL in rabbits. [ABSTRACT FROM AUTHOR]
