PURPOSE: To investigate the effectiveness of 3 surgical preparation techniques in decreasing bacterial contamination of needles and suture material during strabismus surgery. METHODS: Consecutive patients requiring 2-muscle strabismus surgery were randomized into 1 of 3 groups. In Group A, patients' periocular skin and bulbar conjunctivae underwent preparation with 5% povidone-iodine; the drape was placed without regard to eyebrows; and an open wire-loop lid speculum was used. Group B patients underwent the same preparation as Group A patients; however, the eyelashes and eyebrows were scrubbed with 5% povidone-iodine on cotton tip applicators, and the drape was placed to exclude the eyebrows from the surgical field. Group C patients underwent the same preparation as Group B patients; however, a bladed lid speculum was used during surgery to exclude some of the eyelashes from the surgical field. After the procedure, all needles and suture materials were sent separately for aerobic culture. The data were analyzed for differences in contamination rates between the groups. RESULTS: Of 77 patients, 24 (31.4%) had either a needle and/or suture contaminant. Groups A, B, and C had mean contamination rates of 29.6%, 34.6%, and 29.2%, respectively. There was no significant statistical variation in contamination among the 3 groups. The most common organism identified was a coagulase-negative staphylococcus strain. CONCLUSIONS: More meticulous sterile preparation of the surgical field did not result in a meaningful reduction in suture or needle contamination rates during strabismus surgery.
