[Endophthalmitis after phacoemucification surgery].
OBJECTIVE
To study the infective endophthalmitis after phacoemulsification and to discuss the methods for prevention and treatment of this complication.


METHODS
A retrospective analysis was performed on phacoemulsification with implantation of artificial lens underwent in 10 MaiGe Ophthalmological Centers during past 10 years (from 1993 to 2003).


RESULTS
Among 63,372 cases (84,497 eyes) underwent the phacoemulsification, 14 cases suffered infective endophthalmitis with the incidence of 0.02%. In these 14 cases, 11 cases occurred before 1999 (78.6%). There were 5 cases of ruptured posterior lens capsule in these 14 cases (35.7%). Microbiological examination was performed in 11 cases (aqueous or vitreous sample), 7 cases showed positive results (63.6%), including 3 cases of staphylococcus epidermidis (42.8%), 1 case of pseudomonas aeruginosa (16.7%), 1 case of bacilli (16.7%) and 2 cases (33.4%) of fungus (yeast and candida albicans). After the treatment, the vision of 5 patients was recovered to 2.0 or more, 4 cases recovered to hand movement and light perception, enucleation was performed in 3 cases and atrophy of eyeballs occurred in 2 cases.


CONCLUSIONS
The attack rate of endophthalmitis after phacoemucification surgery is 0.02%. The main pathogen is staphylococcus epidermidis. Rupture of posterior lens capsule is one of the main risk factors of endophthalmitis. Observing the operative routine strictly pre-, during and post-operatively can reduce the occurrence of infective endophthalmitis.
