A corneal topographic map is eerily similar to a land contour map, as it displays the surface curvature of the cornea


 


   The cornea is a dome-shaped transparent eye cover that protects the pupil, iris, and anterior chamber of the eye. The cornea works in conjunction with the ear, lens, and anterior chamber to provide 70 percent of the eye's optimal capacity. The corneal topographer is a computer-assisted videokeratography tool that aids in the graphical representation and examination of the cornea's surface.

  The use of corneal topographer tools provides a detailed overview that aids in the identification, control, and treatment of various eye conditions. The rising popularity of laser refractive errors correction and the increased use of contact lenses are driving the forward. Corneal topographers' capacity to only measure four points 3.6mm apart, or over 5% of the corneal surface, as well as a lack of quantitative assessments of regularity, stringent government regulations, high cost of corneal topography devices, and lack of awareness about their use will act as a restraint and further challenge the growth of corneal topographers during the forecast period.

  Corneal topography creates a detailed visual representation of the cornea's shape and power. This type of examination provides your doctor with extremely fine details about the state of your corneal surface. These details are used to diagnose, track, and treat a variety of eye problems. Scheimpflug corneal tomography is a three-dimensional imaging technique that determines the anterior/posterior corneal surfaces, as well as the distribution of corneal thickness.

  A corneal topography test creates detailed 3D maps of the cornea's shape and curvature, making it possible to detect corneal diseases and irregular corneal conditions like swelling, scarring, abrasions, deformities, and irregular astigmatisms. Corneal topography is a painless, non-contact procedure in which the corneal topography device does not come into contact with your eye. If your eye is dry, a few moistening drops may be injected into it to improve the image quality of the topography.

Total Disc Replacement complete details Of Competitive Landscape Executive Summary Development in next decade

Image
    Total disc replacement is a type of back/spine surgery in which an artificial replacement device is used to replace a damaged or degenerated disc in the lumbar or cervical region. A disc replacement, also known as an artificial disc, is a device implanted in the spine that performs the same function as a normal disc in the human body. A total disc replacement , as the name implies, is a procedure that involves the complete or partial exclusion of the disc tissue in order to implant a replacement device into the space between the vertebrae. The prostheses help to maintain spinal curvature and flexibility while reducing or possibly eliminating pain.   Cervical total disc replacement (CTDR) surgery is used to treat patients with degenerative disc disease (DDD). The most common cause of DDD in the cervical region of the spine is neck pain. For the treatment of DDD, a cervical disc replacement procedure is performed in which the degenerated disc is surgically removed and an artificial

Dengue Vaccines development and progress towards vaccine has increased over the past few years

Image
    Dengue fever is a tropical disease spread by mosquitos that are caused by the dengue virus. 3 to 14 days after infection, symptoms appear. A high fever, headache, vomiting, muscle, and joint pains, and a distinct skin rash are all potential symptoms. In most cases, recovery takes two to seven days. In a small percentage of cases, the disease progresses to dengue hemorrhagic fever, which causes bleeding, low levels of blood platelets, and blood plasma leakage, or to dengue shock syndrome, which causes dangerously low blood pressure.   Dengue is spread by several Aides genus female mosquitoes, most notably Aides. The virus has five serotypes; infection with one type usually results in lifelong immunity to that type but only temporary immunity to the others. Subsequent infection with a different type raises the possibility of severe complications. . Dengue vaccines are a vaccine used to protect humans from dengue fever to confirm the diagnosis, a number of tests are available, includ

Non-Contact Torque Sensors Increase Fuel Economy, Improve Ride Comfort and Safety

Torque Sensors     In order to determine the most suitable torque sensor, it is necessary to understand the application and environment. Some applications may require underwater sensors, while others may only need a torque sensor. The type of mounting and assembly is also important. Some are mounted flange-to-flange, while others are mounted shaft-to-shaft. The torque sensors must be able to detect the rotational force in both clockwise and counterclockwise directions.   The most common design for a torque sensor uses bonded strain gauge technology. The strain gauges are bonded to a shaft with a 45-degree inclination. The application will determine the type of cross-section and materials used for the shaft. Depending on the application, a cruciform, square, or a circular cross-section is appropriate. Some torque sensors are made from a combination of these materials.   When selecting a torque sensor, make sure to consider its physical and environmental requirements. The temperature, hu
