Rates of contamination in the anterior chamber are similar in both manual small-incision cataract surgery and phacoemulsification, according to a study.

The prospective randomized study, conducted at a tertiary-care center in southern India, included 150 eyes undergoing cataract surgery. The eyes were divided into two groups for comparison. Seventy-five eyes in group A underwent manual small-incision cataract surgery, and 75 eyes in group B underwent phacoemulsification.

The researchers took aqueous samples from the anterior chamber pre- and postop and conducted standard microbiological analysis.

“Main outcome measures studied were the incidence of positive cultures in aqueous samples obtained from eyes in both groups,” the authors wrote.

The authors concluded that the incidence of contamination in the manual small-incision surgery group (4%) was not significantly different from the phacoemulsification group (2.7%).

The study was published in the June issue of American Journal of Ophthalmology.
