This study was aimed to determine the incidence of bacterial contamination in extracapsular cataract extraction and intraocular lens implantation.
Forty two patients with an age range of 36-88 (62±2) years and underwent planned extracapsular cataract extraction and intraocular lens implantation from a clear corneal incision were evaluated prospectively. Five cultures were obtained from each patient: 1. preoperative conjunctival culture after irrigation of the conjunctiva with povidone-iodine solution, 2. anterior chamber aspirate culture after initial penetration, 3. anterior chamber aspirate culture after suturing, 4. immediate postoperative conjunctival culture, and 5. postoperative conjunctival cultire at bedside. All conjunctival cultures were obtained using calcium alginate swabs.
There were four (9.5%) positive conjunctival cultures. Of the three patients who had positive coagulase (-) staphylococci, one was from the first culture, and the other two were from the fourth culture. One patient had Corynebacterium at the fifth culture. There were no growth from intraocular aspirates. None of the patients showed any sign of endophthalmitis or increased inflammation.
Absence of bacterial growth from the intraocular aspirates in spite of positive conjunctival cultures may be related to preoperative patient preparation, surgical technique or both. Anterior chamber tolerance to low levels of bacterial load might explain absence of clinical inflammation.Keywords: Extracapsular cataract extraction, Culture,
