Using an objective lens in contact with the surface of the eye, the focal point is scanned in three planes (X, Y, and Z axes) to reconstruct the entire image of the specimen with current resolution capabilities of 9 μm in the Z-axis, 0.5–1.0 μm for the X-Y axis, and 1500 μ...
The TB50-336 is the smallest Cobra of the lot with its 336 sensor and 50 mm aperture. It has one objective lens because it's a thermal biocular. It's been built with a FLIR Tau 2 17 micron sensor with 800 x 600 display resolution and a 60 Hz refresh rate. Optical magnification is...
Numerous aspects unrelated to the active agent, such as patient care, formula- tion and disease variability can influence both objective and sub- jective measurements. The widely recognized phenomena known as the "placebo effect," "the Haw- thorne effect" and "regression toward the mean" are ...
A lens plate structure includes the one-way magnification ocular lens combined with a first prism, a second prism, and a magnifying lens. An image plate of one of a smartphone, a mobile phone, and a tablet PC can be inserted into or separated from a mounting holder structure. The lens ...
The objective of this study was to determine the expression and production of SFTA3 at the healthy human ocular surface and to investigate potential differences in the presence of dry eye disease (DED). SFTA3 expression was analyzed by western blot analysis, ELISA as well as by immunohistochemist...
The clear acrylic over the iris acts as a lens and causes the magnification of the iris. However, the research on the magnification of the clear acrylic resin is still lacking. Hence, this study aimed to investigate the magnification of the iris in the ocular prosthesis with various thickness...
Conversely, a comprehensive ocular surface workup with automated quantitative measurements may overcome these drawbacks, thus improving the objective monitoring of the disease course after treatment [38]. In the present study, NIBUT, LLT, non-contact meibography, and tear osmolarity have been ...

Introduction Infection with Pseudomonas aeruginosa (P. aeruginosa), an opportunistic, Gram-negative bacterium, is often associated with microbial keratitis, especially in extended-wear contact lens users [1–3]. Pseudomonas keratitis develops rapidly and elicits an acute inflammatory response in cornea, ...
