Reducing the risk for endophthalmitis after cataract surgery: Population-based nested case-control study: Endophthalmitis Population Study of Western Australia sixth report
JCRS Pages 269-280 (February 2007)
To characterize operative and nonoperative risks for the potentially blinding complication of endophthalmitis after cataract surgery.
Setting
Ophthalmology services for the whole state of Western Australia.
Methods
This retrospective population-based nested case-control study in Western Australia covered the period between 1980 and 2000.
Wound location, suturing the wound, and type of cataract operation did not affect the risk for postoperative endophthalmitis. Antibiotic prophylaxis reduced the risk, but only if given as a subconjunctival injection . The risk for endophthalmitis was greater with same-day surgery than with admission the day before surgery. A concurrent eyelid procedure was a substantial risk. Surgeons within 2 years of obtaining specialist qualifications were more likely to have a case of endophthalmitis, although this was partly the result of more posterior capsule breaches. Posterior capsule breach increased the risk when it occurred in private hospitals,but not in public hospitals.
Conclusions
Nonoperative as well as operative factors are important in the prevention of endophthalmitis. Subconjunctival injection of antibiotics appears to be beneficial for endophthalmitis prophylaxis. The model showed that active risk management strategies designed to optimize hospitalization and chemoprophylaxis may reduce the incidence of endophthalmitis by up to 81%.
