Peroperative microbial contamination of anterior chamber aspirates during extracapsular cataract extraction and phacoemulsification.

BACKGROUND The normal conjunctival flora is one of the main sources of intraocular contamination during cataract surgery. The theory that the positive anterior chamber (AC) pressure during phacoemulsification (phaco), and the smaller wound utilised, might reduce the rate of contamination was studied. METHODS The peroperative AC aspirates of 210 consecutive patients undergoing cataract surgery...

Lack of effect of preoperative norfloxacin on bacterial contamination of anterior chamber aspirates after cataract surgery.

Eighty patients undergoing routine standardised extracapsular cataract surgery with lens implantation were divided randomly into two groups in a prospective double blind study comparing effects of preoperative norfloxacin eyedrops with placebo on bacterial contamination of anterior chamber aspirates after surgery. Pathogenic organisms were identified from 19 (24%) of the aspirates. The most com...

Anterior chamber bacterial contamination in cataract surgery

BACKGROUND The incidence of postoperative endophthalmitis has reduced during last several years to <0.01%; however, its associated complications continue to be devastating. Several sources of infection, including contamination by air, solutions, surgical instruments, intraocular lens, and wound leakage have been identified. The objective of this study was to evaluate the surgical technique, ant...

Depth of anterior chamber after cataract extraction.

A total of 80 patients with senile cataract had the anterior eye chamber depth measured optically by means of Haag-Streit's attachment II. The distance to the pupillary border was 2.59 +/- 0.05 mm (mean +/- SEM) preoperatively. It increased gradually after cataract extraction to 3.33 +/- 0.04 mm, measured 4 months after the operation. The increase of depth was the greatest in patients with a fl...
