Submit Manuscript | http://medcraveonline.com but Helmholtz’s hypothesis [5,6] is one of the most accepted theories that try to explain it. According to the Helmholtz ́s model, the contraction of the ciliary muscle would allow relaxation of crystalline capsule, which, by elastic contraction, would deform the lens, increasing its thickness and, therefore, the optical power. When the ciliary muscl...

Open angle glaucoma (OAG) necessitating surgery has traditionally been treated with filtering procedures using antifibrotics. Unfortunately, such filtering procedures are not without the risk of postsurgical complications. Increasing interest in blebless surgery has led to innovative surgical procedures aimed at rejuvenating the natural trabeculo canalicular outflow pathway. Circumferential cat...

The application of Ultra-High-Performance Concrete (UHPC) materials in rehabilitating bridges and constructing primary bridge components is increasing rapidly across the world because their superior strength durability characteristics when compared to regular concretes. However, there have been few new constructed using UHPC with formworks, ready-mix trucks, construction equipment. This paper p...

Precast post-tensioned segmental (PPS) bridge piers mitigate global and local damages of structures through natural hinges (joints between their segments) rocking motion segments. The application the PPS is currently growing in Accelerated Bridge Construction (ABC) where segments are manufactured offsite with higher quality, assembled onsite a short time. Structural vulnerability analysis very ...

BACKGROUND Despite the importance of soft tissue balancing during total knee arthroplasty (TKA), all estimating techniques are dependent on a surgeon's manual distraction force or subjective feeling based on experience. We developed a new device for dynamic gap balancing, which can offer constant load to the gap between the femur and tibia, using pneumatic pressure during range of motion. MET...

Motion platforms can be used to provide vestibular cues in a driving simulator, and have been shown to reduce driving speed and acceleration. However, motion platforms are expensive devices, and alternatives for providing motion cues need to be investigated. In independent experiments, the following eight low-cost nonvestibular motion cueing systems were tested by comparing driver performance t...

Purpose. The object of this study was to investigate the role of the suture stent regarding its impact on reduction of intraocular pressure (IOP) in canaloplasty based on the distension of the inner wall of Schlemm's canal. Methods. Nineteen glaucoma patients who underwent canaloplasty with successful positioning of the tensioning suture were included. The measurements were analyzed using linea...
