BACKGROUND/AIM Acrylic lens size and shape may influence the rate of posterior capsule opacification (PCO) and need for Nd:YAG capsulotomy. The aim of this study is to compare the Nd:YAG capsulotomy rate of the three piece acrylic/PMMA AcrySof MA series lens with the one piece acrylic AcrySof SA series lens. METHODS 434 eyes of 329 patients who had cataract extraction and implantation of one ...

Objective: To report opacification of hydrophilic acrylic and silicone foldable intraocular lenses (IOL). Designs: Case series. Participants: Five patients with IOL opacification. Results: We report five eyes of five patients with late opacification of the intraocular lens (IOL). Three patients had hydrophilic acrylic (SC60B-OUV-MDR, Inc), two had silicone IOL (Allergan SI30NB). Two out of the ...

nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. the better mechanical properties can be obtained ...

Biocompatibility of biomedical devices can be improved by endothelialization of blood-contacting parts mimicking the vascular endothelium's function. Improved endothelialization might be obtained by using biomimetic coatings that allow local sustained release of biologically active molecules, e.g. anti-thrombotic and growth-inducing agents, from nanoliposomes. We aimed to test whether incorpora...

Data dealing with successful or unsuccessful acrylic tooth implants have accumulated gradually during the past 20 years. Flohr' studied plastic material as a possible substitute for natural teeth by placing screw-type acrylic roots into surgically created alveolar sockets. He reported that normal connective tissue formed against the acrylic, and only minimal infiltration occurred. Hodosh, et al...

DEDICATION To my parents, thank you for always encouraging me to explore the world. v ACKNOWLEDGEMENTS I would to thank my advisor, Julie M. Goddard, for her guidance and support throughout my degree. Thanks are also due to the entire Bioengineering group, especially Luis Bastarrachea for his mentorship and advice. I would also like to extend my gratitude to my committee members, Amanda Kinchla...

This work aims to reveal the effect of a high amount cellulose fibers on durability and protective behavior bio-based wood paint. The influence filler morphology coatings was investigated by scanning electron microscopy observations, while paint evaluated exposing samples UV-B radiation continuous thermal shocks. Infrared spectroscopy analysis, colorimetric inspections, adhesion tests microscop...

Coating materials are used on surfaces such as steel and ceramic to offer protection, corrosion resistance, wear erosion a thermal barrier, or aesthetics. Although organic coating epoxy resins, silane, acrylic widely used, there restrictions drawbacks associated with their use, including the ease which cracking, hazardous harmful human health environment, peeling, deterioration occur. Organic m...

PURPOSE To investigate the ability of an open capsule device to prevent posterior capsule opacification. METHODS A total of 40 eyes of 20 New Zealand white rabbits were randomly divided into six similar groups of 6 to 7 eyes each. After crystalline lens evacuation, one control group (group A) was implanted with a hydrophilic acrylic intraocular lens and no device, and another control group (g...

This study analyzes the limitations of low-frequency EIS impedance modulus as a tool to describe protective properties organic coatings subjected accelerated aging tests. Acrylic clear-coated steel and hot-dip galvanized were exposed test methods such neutral salt spray chamber Prohesion for up 2000 3000 h, respectively. During exposure, monitored by visual inspection. We observed significant d...
