Purpose We improve the intraocular open-capsule devices (IOCD) for the prevention of posterior capsule opacification (PCO). Methods A total of 45 New Zealand rabbit eyes were divided into six similar groups after crystalline lens evacuation. Each group was implanted with a hydrophilic intraocular lens (IOL) and a hydrophilic IOCD of different designs. In the first experiment (Part A), a squar...

AIM To evaluate the impact of 4 different intraocular lenses (IOLs) on posterior capsule opacification (PCO) by comparing the neodymium: yttrium-aluminum-garnet (Nd:YAG) laser capsulotomy rates. METHODS This retrospective study included 4970 eyes of 4013 cataract patients who underwent phacoemulsification and IOL implantation between January 2000 and January 2008 by the same surgeon at one cl...

OBJECTIVE To determine the incidence and the risk factors involved in the development of the three main postoperative capsular complications: posterior capsule opacification (PCO), capsular bag distension syndrome (CBDS), and anterior capsular phimosis syndrome (ACP). SUBJECTS, MATERIAL AND METHODS A retrospective cohort study was conducted on 801 patients submitted to cataract surgery in the...

This study was designed to investigate the effect of environmental factors on the appearance of polycystic ovaries (PCO) during the first two decades of life. Ninety-four female-female twins who underwent a transabdominal ultrasound at the Royal Hospital for Women were sent a questionnaire asking about their birth details, feeding history as a baby, childhood illnesses and vaccination as w...

Modern cataract surgery with implantation of an intraocular lens (IOL) is an increasingly safe and successful procedure, though complications still occur. This thesis addresses the most common complication, posterior capsule opacification (PCO) and the rare but serious complication postoperative endophthalmitis (POE). The pathogenesis of PCO is multifactorial and several surgical and IOL-relate...

Abstract Temporal and spatial tuning of the refractive index optical thin films is desired for flat optics applications. The redistribution mobile ions in mixed ionic-electronic conductors (MIEC) has been demonstrated to serve as a viable means achieving down nanoscale. Here we studied dynamic range achievable index, MIEC oxide – Pr x Ce 1? O 2? ? (PCO), = 0.1, 0.2 0.4, at 500 °C, by in-situ sp...

background and objective: uterus of rat with polycystic ovary (pco) may show pathological features. we provided pathological evidence for the rat uterus with no-induced pco.    materials and methods: wistar rats (weighing 200-250 g) were kept diestrous to receive l-arginine (50 mg/kg) intraperitoneally (i.p.) for 9 days/once a day. control group solely received saline (1 ml/kg, 9 days/once per ...

RATIONALE Throughout at least the next century, CO(2) fertilization and environmental stresses (e.g. nutrient, moisture, insect herbivory) are predicted to affect yields of economically important crop species. Stable isotopes of carbon are used to study plant stresses, which affect yields, but a growth chamber design that can be used to isolate the effects of environmental stresses on crop-size...
