Implantation of phakic refractive lenses PRL® (Phakic Refractive Lens; IOLTech/Carl Zeiss Meditec AG, Jena, Germany) is one of the options available for the correction of moderate to high myopia, although there are few reports on the outcomes. In those cases where a corneal laser-assisted surgical procedure is not indicated because of the great amount of tissue to be removed, small optical zone...

PURPOSE The present study aimed to compare the postoperative contrast sensitivity functions between wavefront-guided LASIK eyes and their contralateral wavefront-guided PRK eyes. METHODS The participants were 11 healthy subjects (mean age=32.4 ± 6.2 years) who had myopic astigmatism. The spatial contrast sensitivity functions were measured before and three times after the surgery. Psycho and ...

conclusions patients’ experiences after cardiac surgery indicated the need for the consideration of holistic care and supportive intervention programs after surgery to promote recovery and a better quality of life following cardiac surgery. results the data analysis revealed three main themes and 11 subthemes, categorized as conceptual and abstract, based on their nature: concern of going out t...

results of 153 patients, 96.8% received pc and 54.9% transfused ffp during or after surgery. most of the transfusions were done after operation in intensive care unit (icu). also, 20% and 17% of the patients underwent transfusion of more than 6 units of pc and ffp, respectively. the mean left ventricular ejection fraction of the patients was 42.5 ± 10.9%. a significant number of patients had an...

background catheterization of central veins is a routine technique which is widely used in general hospitals and medical intensive care units. it should be carefully performed and managed to prevent adverse side effects. case presentation in this case report, we describe a case of lost guide wire during central venous catheterization, which was successfully treated with a minimally invasive sur...

objectives the objective of this study was to evaluate factors influencing waiting time in patients of heart surgery centers, and to make recommendations for health-care policy-makers for reducing waiting time and increasing the quality of services from this perspective. patients and methods this cross-sectional study was performed in 2013. after searching articles on pubmed, elsevier, google s...

background: injured phrenic nerve secondary to cardiac surgeries is the most common cause of diaphragmatic paralysis (dp) in infants. the aim of this study was to determine the risk factors for dp caused by congenital heart defect corrective surgeries in pediatrics. methods: this cross-sectional study, conducted in a 2-year period (2006 – 2008), included 451 children with congenital heart disea...

The use of ultrashort pulse lasers is current in refractive surgery and has recently been extended to corneal grafting (keratoplasty). When performing keratoplasty, however, permanent degradation of the optical properties of the patient's cornea compromises the penetration depth of the laser and the quality of the incisions, therefore causing unwanted secondary effects. Additionally, corneal gr...

conclusions due to the shorter :union: time, to some extent less complication rate and comparable functional and clinical results, the authors recommend to use the mipo technique in treating the mid-distal humeral shaft fracture. results the median of :union: time was shorter in the mipo group (4 months versus 5 months). the time of surgery and functional outcomes based on the ucla and meps sco...
