Povidone-Iodine and the Prevention of Bacterial Contamination of the Eye During Extracapsular Cataract Surgery

Does Surgical Technique Influence Cataract Surgery Contamination?

“…Microorganisms were recovered from the conjunctival swabs in 13% of our patients disinfected with povidone-iodine. This scrub reduced the number of microorganisms on the conjunctiva and was especially active against Gram(-) organisms (2,11). Our study confirmed this, since we had no gram(-) growth in conjunctival swab or anterior chamber cultures.…”

“…Sherwood et al (4) found 29% contamination with the traditional large-incision nuclear expression tech-nique. Walters et al (2) found 4% and 5% contamination rates with the same surgical technique but different presurgical preparations. With PE Assia et al (1) found 3.9% and Samad et al (3) found 5% contamination.…”

“…To prevent the development of endophthalmitis after cataract surgery approaches such as application of topical antibiotics, irrigation of the ocular surface with povidone-iodine, adding antibiotics to the irrigation solutions or injecting them directly into the anterior chamber or into the capsular bag have already been used (2,8,11,21,22).…”

Transcorneal aspiration for management of primary iris cysts in the standing horse

“…Additionally, a large human study has reported no complications following anterior chamber paracentesis with no pre‐operative antisepsis (Van der Lelij & Rothova, 1997 ). When considering ocular surgery, multiple studies have shown no difference in positive bacterial cultures when using povidone‐iodine compared to a placebo for cataract surgery (Soto & Mendivil, 2001 ; Walters et al., 1993 ). The majority of bacterial contamination in the eye originates from the eyelid, periorbital skin and conjunctiva (Leong et al., 2002 ).…”

Prophylaxe der Ophthalmia neonatorum

“…Von den derzeit zur Verfugung stehenden Substanzen ist Polyvidon-Jod am geeignetsten, da die Substanz Ober ein extrem breites Wirkspektrum verfugt and eine nur kurze Einwirkzeit [21][22][23][24][25] benotigt. Die Verwendung in 2,5% Losung erscheint sinnvoll, da in dieser Konzentration in zahlreichen Studien eine deutliche Reduktion der Inzidenz der Ophthalmia neonatorum nachgewiesen werde konnte, and die deutliche Uberlegenheit von 2,5% Polyvidon-Jod beispielsweise gegenuber Silbernitrat 1% oder Erythromycin 0,5% belegt wurde [1,14].…”
