title: A randomized, controlled comparison of anterior and posterior periocular injection of antibiotic in the prevention of postoperative endophthalmitis.
abstract: A randomized, controlled, prospective comparison of the effectiveness of anterior and posterior injections of antibiotics in the prevention of endophthalmitis following cataract extraction was carried out in a village hospital in Pakistan.
