Clinical features and treatment of endophthalmitis after cataract surgery
Abstract
PURPOSE: The study analyzes the frequency of acute endophthalmitis occurrence after cataract surgery, the risk factors, characteristic symptoms, and the effectiveness of peri-operative prevention measures.
MATERIAL AND METHODS: The study retrospectively analyzed 59 670 cases of patients operated for cataract in 2017-2021. To prevent infections, patients received four instillations of third generation fluoroquinolone (quinolone antibiotic) in the course of two days prior to cataract phacoemulsification (PE), and two instillations immediately (1 hour and 30 minutes) before the surgery; three-minutes treatment of the cornea, conjunctival sac and periocular skin with 5% povidone iodine before the surgery; and as the last step of surgery, patients received subconjunctival injection of 0.05 g cefazolin with 2 mg dexamethasone. Follow-up after surgery included four injections of 0.5% levofloxacin in the course of 7-10 days, and 0.1% dexamethasone for two weeks, or fixed combination of tobramycin and dexamethasone four times per day for two weeks. The criteria for acute endophthalmitis are: loss of spatial vision, absence of red reflex, pronounced thickening of the choroid, suspended particulates in the retrovitreal space and the vitreous observed with ultrasonography in the early postoperative period (day 4-7 after surgery).
RESULTS AND DISCUSSION: There were 32 patients (0.054%) diagnosed with acute endophthalmitis. Posterior capsule rupture was the main complicative risk factor…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 670 participants or records.
