BACKGROUND The purpose of this study was to evaluate pars plana vitrectomy (PPV) with phacoemulsification in the vitreous cavity for treatment of complete posterior dislocation of the lens without any damage to the lens capsule. METHODS We evaluated factors such as cause of dislocation, scleral fixation of an intraocular lens (IOL), preoperative and postoperative visual acuity, corneal endoth...

Purpose Retinal prostheses provide vision to blind patients by eliciting phosphenes through electrical stimulation. This study explored whether character identification and image localization could be achieved through direct multiple-electrode stimulation with a suprachoroidal retinal prosthesis. Methods Two of three retinitis pigmentosa patients implanted with a suprachoroidal electrode arra...

JULY 2014 CATARACT & REFRACTIVE SURGERY TODAY 55 M any techniques have been described for correcting aphakia with inadequate capsular support. The most common IOLs that are used include anterior chamber, posterior chamber, iris-fixated, and scleral-sutured IOLs; however, there is no current agreement on the ideal technique or technology. The Artisan aphakia lens (Ophtec; marketed as the Verisys...

Purpose. This system review studied the efficiency and safety of canaloplasty (CP) and compared the outcomes between CP and trabeculectomy (TE). Methods. Literatures were searched in PubMed and EMBASE. The meta-analysis was conducted on the postoperative outcomes in CP and then on the differences of outcomes between CP and TE. Results. In the meta-analysis, IOP decreased by 9.94 (95% CI 8.42 to...

Surgical Indications • Congenital corneal disorders • Corneal dystrophies • Corneal degenerations • Corneal scarring/opacifi cation – Infection – Infl ammation – Trauma • Graft failure • Corneal decompensation – Pseudophakic – Aphakic – Iatrogenic – Dystrophic – Traumatic Surgical Instrumentation • Operating microscope • Microsuturing instruments – Fine-toothed 0.12-mm forceps – Fine-tip needle...

Introduction Anti-glaucoma medicines, laser surgery and incisional surgery all seek to lower the intraocular pressure (IOP). Incisional surgery is indicated when medical treatment and/or laser surgery have failed, are likely to fail or are not available or practical. The most standard surgical procedure is trabeculectomy (or some variation thereof e.g. ExPRESS shunt): aqueous is shunted from th...

abstract background: high resolution ct scan has made early diagnosis of intraventricular hemorrhage (ivh) easier. posttraumatic intraventricular hemorrhage has been reported to a greater extent because of the ct scan. methods: 904 patients were admitted in the nsicu from march 2001 to march 2002 with severe closed head injury, of those only 31 patients with intraventricular hemorrhage (gcs les...

Purpose To determine clearance kinetics and routes of clearance of molecules from the suprachoroidal space (SCS) of live New Zealand White rabbits. Methods Suprachoroidal space collapse rate and pressure changes after microneedle injection into SCS were determined. Fluorescent fundus images were acquired to determine clearance rates of molecules ranging in size from 332 Da to 2 MDa. Microneed...

OBJECTIVE One strategy to improve the effectiveness of prosthetic vision devices is to process incoming images to ensure that key information can be perceived by the user. This paper presents the first comprehensive results of vision function testing for a suprachoroidal retinal prosthetic device utilizing of 20 stimulating electrodes. Further, we investigate whether using image filtering can i...
