Results: 51 patients underwent phacoemulsification under topical anesthesia and 49 patients underwent phacoemulsification under peribulbar anesthesia. No statistical differences were found in surgery duration, intra-operative complications, pain, blood pressure or Oxygen saturation (SPO2). Topical group did not require additional subconjunctival injection. 4/49 (8.16%) in peribulbar group requi...

BACKGROUND Advances in optogenetics have led to first reports of expression of light-gated ion-channels in non-human primates (NHPs). However, a major obstacle preventing effective application of optogenetics in NHPs and translation to optogenetic therapeutics is the absence of compatible multifunction optoelectronic probes for (1) precision light delivery, (2) low-interference electrophysiolog...

Observation and Control of Interfacial Defects in ZnO/ZnSe Coaxial Nanowires W.A. Bhutto, Z.M. Wu∗, Y.Y. Cao, W.P. Wang and J.Y. Kang∗ Fujian Key Laboratory of Semiconductor Materials and Applications, Department of Physics, Xiamen University Xiamen 361005, P.R. China ZnO/ZnSe coaxial nanowires with di erent ZnO core diameters were synthesized by using a two-step chemical vapor deposition. The ...

We designed a specially designed coaxial spinneret in this study. The inner stainless-steel needle was connected to the inner plastic syringe just like the traditional one. The outer stainless-steel needle was replaced by a plastic nozzle, and connected to the outer plastic syringe. The tip of the inner stainless-steel needle was shortened 2 cm from the tip of the outer plastic nozzle. This str...

AIM To evaluate the effect of torsional mode phacoemulsification on central corneal thickness, corneal endothelial cell density, and morphology in eyes with/without pseudoexfoliation (PEX) syndrome. METHODS Fourty-two consecutive patients with and 42 patients without PEX as a control group scheduled for cataract surgery was studied. Phacoemulsification, using OZiL IP system, was performed wit...

PURPOSE To evaluate the incidence of retinal detachment (RD) after cataract surgery performed by phacoemulsification in very highly myopic eyes. DESIGN Retrospective, paired-eye, case-control trial. PARTICIPANTS AND INTERVENTION We assessed the development of RD in 930 eyes from 930 subjects (mean age = 62.5 +/- 8.5 years) affected by very high myopia (between -15 and -30 diopters) undergoi...

OBJECTIVES To evaluate changes in anterior chamber depth (ACD) and postoperative refractive outcomes after combined phacovitrectomy. MATERIALS AND METHODS This study included 10 eyes of 10 patients that underwent combined phacovitrectomy (study group) and 14 eyes of 14 patients that underwent phacoemulsification surgery (control group) at İstanbul Medipol University Ophthalmology Department. ...

The effect of phacoemulsification, with the Cavitron-Kelman instrument, on the corneal endothelium of rabbit and cats was studied by scanning electron microscopy and nitroblue tetrazolium staining. The various steps of the procedure were examined separately. Irrigation of the anterior chamber of the eye with balanced salt solution (Plasma-Lyte) for ten minutes caused no cell damage. Ultrasound ...

purpose: to compare aspheric and spherical hydrophilic intraocular lenses (iols) in terms of contrast sensitivity and visual acuity in photopic and mesopic conditions. methods: this triple-blind randomized clinical trial was performed on 40 eyes of 40 patients at al-zahra eye center, zahedan, iran. the eyes were randomized to standard phacoemulsification procedure with spherical (adapt, b&l;) o...

purpose: to demonstrate an approach to the problems of cataract surgery in extensive iridoschisis methods: four eyes of 2 patients with extensive iridoschisis had cataract surgery by the same surgeon using the techniques that resembled techniques for phacoemulsification in intraoperative floppy iris syndrome (ifis). we used low flow parameters on phacoemulsification, used super-cohesive ophthal...
