PURPOSE To compare the intraoperative and short-term postoperative outcomes of cataract surgery performed with torsional mode and conventional ultrasound mode using the Infiniti Vision System (Alcon Laboratories). SETTING Cataract Service, Zhongshan Ophthalmic Center, Sun-Yat-Sen University, Guangzhou, China. METHODS In this randomized comparative(More)
BACKGROUND Higher-order aberrations and contrast sensitivity were evaluated in patients who underwent phacoemulsification cataract extraction followed by implantation of aspherical, monofocal or multifocal intraocular lens (IOL) replacements. METHODS In this comparative trial, 124 patients with an average age of 66.8+/-5.2 years and their 124 eyes were(More)
The first human infection with avian influenza A(H7N9) virus was reported in Shanghai, China in March 2013. An additional 32 cases of human H7N9 infection were identified in the following months from March to April 2013 in Shanghai. Here we conducted a case-control study of the patients with H7N9 infection (n = 25) using controls matched by age, sex, and(More)
BACKGROUND A wide range of organisms that enter the eye following ocular trauma can cause endophthalmitis. This study was to investigate the spectrum of pathogens and antibiotic susceptibility of bacterial isolates from a large cohort of post-traumatic endophthalmitis cases. METHODS A retrospective study of 912 post-traumatic endophthalmitis patients(More)
BACKGROUND AND OBJECTIVE The authors describe the non-chopping rotation and axial rotation phacoemulsification techniques and compare them with the quick chop technique in terms of efficacy and safety. PATIENTS AND METHODS A prospective, randomized, comparative study of 654 eyes of patients with cataracts who underwent phacoemulsification and intraocular(More)
BACKGROUND Suture exposure remains to be a potential problem of transscleral fixated posterior chamber intraocular lens (PCIOL). We report a modified technique to minimize the risk of suture exposure for the transscleral fixation of PCIOL. METHODS The modified surgical technique is as following: at first, two 3 mm × 4 mm square scleral pockets were(More)
PURPOSE We have manufactured a novel human foldable capsular vitreous body (FCVB). In this article, we determine whether the human FCVB releases levofloxacin in vitro and evaluate the release characteristics. METHODS Levofloxacin at dosages of 100, 250, and 500 μg/mL in 4.0 mL H2O was injected into the novel human FCVB; then, the capsules were immersed in(More)
This study aimed to identify the microbial etiology of infectious endophthalmitis and to determine the antibacterial susceptibilities of bacterial isolates at an eye hospital in South China. A retrospective analysis was carried out on 330 patients with clinically diagnosed infectious endophthalmitis who underwent microbiological evaluation from January 2010(More)
PURPOSE To study the clinical characteristics, therapeutic efficacy and investigate prognostic factors of endogenous endophthalmitis. METHODS Twenty-eight cases (28 eyes) of endogenous endophthalmitis were surveyed retrospectively. The clinical characteristics, primary infection foci, predisposing systemic disease, complications, pathogens examination,(More)
PURPOSE To evaluate the effects of long-term tamponade with silicone oil on retinal saturation. METHODS A total of 49 eyes that received tamponade with silicone oil were included. The patients were divided into 3 groups (3-6 months, 6-9 months, and >9 months) according to the duration of silicone oil tamponade. Retinal oximetry was performed using the(More)
