BACKGROUND several studies have shown comparable visual outcomes of SICS and phacoemulsification (Gogate et al 2007, Ruit et al 2007). OBJECTIVE to compare the safety and efficacy of different types of surgical procedures (phacoemulsification versus SICS) for cataract surgery in immature cataract. MATERIAL AND METHODS a prospective randomized controlled trial was carried out involving 93 an...

We determine the plasmon dispersion relation in coaxial waveguides composed of a circular channel separating a metallic core and cladding. Optical transmission measurements are performed on isolated coaxial nanoapertures fabricated on a Ag film using focused ion-beam lithography. The dispersion depends strongly on the dielectric material and layer thickness. Our experimental results agree well ...

Coaxial technique is extensively applied to facilitate percutaneous lung lesion biopsy. However, the impact of coaxial technique on diagnostic accuracy remains undecided. We reviewed 485 patients who underwent percutaneous CT-guided needle biopsies of lung lesions in our hospital. All of these biopsies were performed using either a cutting needle alone (n = 268) or a cutting needle combined wit...

PURPOSE A systematic review and meta-analysis comparing the safety, efficacy, and expenses related to phacoemulsification versus manual small incision cataract surgery (SICS). METHODS PubMed, Cochrane, and Scopus databases were searched with key words manual SICS 6/18 and 6/60; astigmatism and endothelial cell loss postoperatively, intra- and post-operative complications, phacoemulsification,...

background: we administered paracetamol and fentanyl at the beginning of phacoemulsification cataract surgery. we think that paracetamol administered alone is as effective as fentanyl in treating pain after cataract surgery with fewer side effects during operation and in post anesthesia care unit (pacu). the goal of this study was to compare to the postoperative pain relief effect of paracetamo...

This paper presents a modal-expansion analysis of the electromagnetically coupled coaxial dipole antenna. The analysis of the antenna problem is initially simplified using the even-odd mode excitation and then the resultant half structure is divided into two parts; one is the characterization of a coaxial feeding network and the other is the modeling of a sleeve monopole antenna driven by a coa...

PURPOSE To determine the role of cavitational energy as a mechanism responsible for the emulsification of the lens during phacoemulsification. SETTING Clinica Ophthalmologica Pasteur, Santiago, Chile. METHODS Cavitation and its relationship to phacoemulsification power were documented using a combination of light sources, high-speed video recording techniques, and computerized control and b...

BACKGROUND/AIM Cataract surgery has become one of the safest procedures in medicine thanks to advances in technology and surgical techniques. Although minimal, we still witness different complications. The aim of this study was to compare visual outcome and complication rate in different techniques of cataract surgery, ie in cataract surgeries with various corneal incision width. METHODS The ...

PURPOSE To elucidate the impact of phacoemulsification on aqueous monocyte chemoattractant protein-1 (MCP-1) levels, and identify its cell origin. METHODS For clinical study, aqueous humor samples were collected before and after surgery (17.0 ± 4.0 months postoperatively) from 21 cataract cases that underwent phacoemulsification and intraocular lens (IOL) implantation. Aqueous MCP-1 levels we...

PURPOSE To evaluate the results of intravitreal phacoemulsification with torsional hand piece in eyes with posteriorly dislocated lens fragments. METHODS In this prospective, interventional case series, 15 eyes with retained lens fragments following phacoemulsification were included. All patients underwent standard three-port pars plana vitrectomy and intravitreal phacoemulsification using sl...
