Campbell Laboratory of Ophthalmic Microbiology (A.M., E.G.R., R.M.Q.S., D.K.D.), Department of Ophthalmology, University of Pittsburgh, Pittsburgh, PA; Associated Retina Consultants (J.L.O.), Phoenix, AZ; and San Antonio Eye Center (J.W.), San Antonio, TX.
Objective: To compare endophthalmitis rates after cataract extraction in patients with different preoperative prophylaxis: double povidone-iodine preparation with topical antibiotics versus a control group.
Methods: All cases of postoperative endophthalmitis over the last 17 years were reviewed. Incidence rates of endophthalmitis for all cataract surgeries (current procedural terminology codes 66982 and 66984) performed by 26 surgeons were calculated.
Comparison of iodine compounds and levofloxacin as postoperative instillation; conjunctival bacterial flora and antimicrobial susceptibility following cataract surgery.

Article Synopsis
- The study aimed to compare the effectiveness of iodine compounds and levofloxacin in cleaning the conjunctival sac after cataract surgery.
- It involved 128 patients who received either levofloxacin or diluted iodine drops for a week after surgery, with bacterial cultures taken before surgery and at one and two months post-op.
- Results showed that both treatments reduced bacterial contamination initially, but levofloxacin was more effective in reducing bacterial DNA; however, it also led to the emergence of more resistant bacteria over time, unlike the iodine treatment.
Liposomal Ozonated Oil Ensures a Further Reduction in the Microbial Load Before Intravitreal Injection: the "OPERA" Study.
Ophthalmol Ther
October 2024
Department of Translational Biomedicine Neuroscience, "Aldo Moro" University of Bari, Piazza Giulio Cesare, 11, 70122, Bari, Italy.
Article Synopsis
- This study aimed to evaluate the effectiveness of a new ophthalmic solution made from ozonated sunflower oil in liposomes combined with hypromellose against the standard povidone iodine 5% in reducing bacterial presence in patients before eye injections.
- The research involved 195 patients, where one eye received the new treatment (Ozodrop and BlefOX) while the other was treated with povidone iodine, with swabs taken from both eyes to measure microbial levels before and after treatment.
- Results showed that the new treatment significantly decreased bacterial loads more than povidone iodine alone, indicating its potential as a superior antiseptic for ocular procedures.

Objectives: the aim was to compare 2 drops of either 5% chloramphenicol, 1% povidone-iodine or 5% povidone-iodine before cataract surgery on reducing the colonisation of bacterial flora in the conjunctiva.
Design: This was a double-blind, randomised clinical trial study.
Setting: Patients referred to Shahid Sadoughi Hospital in Yazd, Iran, for cataract surgery were studied.
