Comparative safety study of intracameral levofloxacin versus moxifloxacin for postoperative infection prophylaxis

Purpose: To evaluate the efficacy of combined intraocular injection of gentamycin and clindamycin in prevention of acute posttraumatic bacterial endophthalmitis (APBE) following penetrating eye injuries. Design: Multicenter, randomized, double masked, controlled trial. Participants: Three hundred forty six eyes of 346 patients with penetrating eye injury. Method: Following primary repair, eyes were randomized to receive a 0.1 ml intracameral or intravitreal injection of 40µg gentamycin and 45µg clindamycin (cases), versus intracameral or intravitreal injection of 0.1ml balanced saline solution (controls). All patients received standard prophylactic antibiotic therapy (systemic, subconjunctival and topical). Main outcome measures: Occurrence of endophthalmitis within two weeks after primary repair.

Postoperative endophthalmitis, a possible severe complication of cataract surgery, is an infection of the anterior chamber of the eye caused by bacterial contamination and colonization through surgical incisions. Bacteria are thought to originate mainly from the patient's skin and studies show that bacteria are commonly found in the anterior chamber following surgery. However, innate immune defences are usually able to control and eliminate bacterial growth before postoperative endophthalmitis occurs. Also, due to the low incidence of postoperative endophthalmitis, it is difficult to accurately evaluate preventative methods. This study will examine the efficacy of topical preoperative administration of gatifloxacin (a new fourth generation fluoroquinolone antibiotic) on reduction of bacterial contamination of the anterior chamber following cataract surgery. If the antibiotic is shown to lower bacteria count in cultures from anterior chamber fluid, it has the potential to lower the incidence of postoperative endophthalmitis. Patients undergoing cataract surgery will be notified and asked to participate in the study by the physician in advance of the surgery, provided they do not possess any exclusion criteria. The participants will be randomly split into two groups; one group will receive topical application of gatifloxacin prior to surgery, while the other group will receive no eye drops. During surgery, a small sample of anterior chamber fluid will be removed from the eye and cultured in both broth and enrichment media for all subjects. Bacterial growth, i.e., colony forming units (CFUs), will be used as an indicator of the bacterial contamination of the fluid.

The purpose of the present study is to elucidate the qualitative and quantitative variation of ocular flora after treatment with eyedrops containing 0.6% povidone-iodine in the eye of patients undergoing routine cataract surgery.

The objective of this study is to evaluate the macular and choroidal thickness of patients submitted to intracameral moxifloxacin during the phacoemulsification surgery for endophthalmitis prophylaxis. The investigators propose a randomized clinical trial double-blind. The patients will be divided into two groups: one will receive intracameral moxifloxacin injection during phacoemulsification surgery and the other won't. Both Spectral Domain - Optical Coherence Tomography (SD-OCT) and Enhanced Depth Imaging - Optical Coherence Tomography (EDI-OCT) will be performed for each patient pre-operatively and on the 30th and 60th postoperative days. After collecting, the data will be compared to evaluate if there was any difference in the macular thickness and choroidal thickness between the two groups.

Antibiotics are commonly utilized to reduce the bacterial population of the eye prior to surgery with the assumption that this reduces the risk of endophthalmitis, although it is not clear if this actually occurs. This study will investigate the use of Hypochlorous Acid, a commercially available over the counter (OTC) medication to see if this will reduce the bacterial population prior the cataract surgery.

This is a randomized controlled single blind prospective study evaluating the efficacy of ocular surface sterilization between three different povidone-iodine preparation techniques prior to intravitreal injection. The primary end point is significant different between median colony-forming units pre- and post-sterilization and injection.

Intravitreal injections (IVI) of antiangiogenic agents (AA) have revolutionized the management of age-related macular degeneration (AMD) and diabetic macular edema (DME) in particular. Approximately 600,000 AA IVIs are performed each year in France. Corticosteroid IVIs are an alternative in the treatment of macular edema when it is diabetic or related to venous occlusion, but also due to inflammation. Endophthalmitis is one of the most feared complications after IVI because of its poor prognosis, despite its low incidence (values found in the literature between 0.01% and 0.08%). IVI practices have evolved over the years based on the recommendations of specialized organizations, with the current recommendation not to use antibiotic prophylaxis. The purpose of this study is to study the effect of intravitreal injections of anti-angiogenic agents and corticosteroids on the occurrence of endophthalmitis within 28 days following an injection.

Endophthalmitis is defined as intraocular inflammatory disorder affecting the vitreous cavity that can result from exogenous or endogenous spread of infecting organisms into the eye. Patients presents with reduced or blurred vision, red eye, pain, and lid swelling. Endophthalmitis can progress into panophthalmitis, corneal infiltration and perforation, and finally phthisis bulbi. For exogenous endopthalmitis, the intraocular inflammation occurs due to a breach of the ocular compartment. The infectious agent indirectly introduced into the eye. This usually happens after intraocular surgery such as cataract surgery, vitrectomy, glaucoma filtration surgery, intravitreal injections, and other causes include penetrating ocular trauma or from adjacent periocular tissue. Several prophylactic measures have been taken to reduce the incidence of post-operative endopthalmitis postcataract surgery, this includes the use of pre-operative topical levofloxacin, intrameral cefuroxime, and providone iodine as ocular surface preparation.The proposed study is to evaluate clinical safety of Levofloxacin 1.5% and Moxifloxacin 0.5% on the anterior segment parameters.
