* Bacteria: N. meningitidis, Staphylococcus aureus, S. epidermidis, S. pneumoniae, other streptococcal spp., Cutibacterium acnes, Pseudomonas aeruginosa, other gram negative organisms. * Viruses: Herpes simplex virus. * Fungi: Candida spp. Fusarium * Parasites: Toxoplasma gondii, Toxocara. A recent systematic review found that the most common source of infectious transmission following cataract surgery was attributed to a contaminated intaocular solution (i.e. irrigation solution, viscoelastic, or diluted antibiotic), although there is a large diversity of exogenous microorganisms that can travel via various routes including the operating room environment, phacoemulsifcation machine, surgical instruments, topical anesthetics, intraocular lens, autoclave solution, and cotton wool swabs. Late-onset<unk>  is mostly caused by Cutibacterium acnes. Causative organisms are not present in all cases.<unk>  can emerge by entirely sterile means, e.g. an allergic reaction to a drug administered intravitreally.
