AIM: To study the treatment and predisposing factors of postcataract endophthalmitis after phacoemulsification operation.

METHODS: The clinical data of 8 patients(8 eyes)with postcataract endophthalmitis were analyzed retrospectively from June 2003 to June 2013. Emergent surgery(anterior chamber irrigation, vitrectomy, intravitreal injection)was performed in all patients. Aqueous fluid and vitreous purulence was taken in all patients before vitrectomy for bacterial, fungal culture and drug sensitivity test. The preoperative and postoperative visual acuity, inflammatory reaction and postoperative complications were observed.

RESULTS: All the patients were followed up for 6-12mo.The visual acuity improved significantly at l, 6mo after surgery(P<0.05). Endophthalmitis was controlled in all of eyes after surgery, and no one case had postoperative complications. Seven cases was isolated pathogens, and the main bacteria spectrum of postcataract endophthalmitis was staphylococcus epidermidis and enterococcus faecalis(D group).The two kinds of bacteria were sensitive to vancomycin. The predisposing factors included: advanced age, diabetes, chronic obstructive pulmonary disease, renal failure, tuberculosis.

CONCLUSION: For postcataract endophthalmitis, vitrectomy as early as possible could improve the prognosis and performing the surgery of vitrectomy is effective for postcataract endophthalmitis. Vancomycin is effective antibacterials.
