METHODS All intraoperative complications during cataract surgery were reported prospectively as part of a clinical audit program. The(More)
BACKGROUND AND OBJECTIVE A prospective, randomized, double-blind study was conducted to compare sub-Tenon's anesthesia with retrobulbar anesthesia. PATIENTS AND METHODS One hundred six patients undergoing cataract extraction received either sub-Tenon's anesthesia (55 patients) or retrobulbar anesthesia (51 patients). The number of injections required,(More)
INTRODUCTION The aim of this study was to determine if racial differences exist in the rate of posterior capsule rupture (PCR) during cataract surgery in Singapore. MATERIALS AND METHODS All intraoperative complications during cataract surgery were prospectively reported as part of a clinical audit programme. A retrospective review of all patients who(More)

PURPOSE To investigate the subjective visual experience of patients during cataract surgery under retrobulbar anaesthesia. METHODS One hundred cataract patients who underwent routine extracapsular cataract extraction and intraocular lens implantation under retrobulbar anaesthesia were interviewed by the authors on the same day after their operation(More)
Herpes Zoster Ophthalmicus (HZO) is not an uncommon condition in the elderly and the immunocompromised. The common ocular manifestations include blepharoconjunctivitis, keratitis and uveitis. Dramatic presentations like orbital apex syndrome and superior orbital fissure syndromes occur rarely in patients with herpes zoster meningo-encephalitis. We report a(More)
PURPOSE To review the visual and surgical outcome of planned intracapsular cataract extraction (ICCE) and anterior chamber intraocular lens (AC IOL) implantation for subluxated crystalline lenses. METHODS Eight eyes of 7 patients with subluxated lenses which underwent planned ICCE, AC IOL implantation and peripheral iridectomy by one surgeon between(More)
A great variety of Intraocular Lenses (IOLs) made by various manufacturers are now available to the Implant Surgeon. The Surgeon must decide which IOLs are better than others, and be aware of physical characteristics of IOLs that would be potentially dangerous to the intraocular structures. The Scanning Electron-Microscope (SEM) is now recognised as a(More)
