[…] diameter was rounded up to the first decimal place. the anterior corneal refractive power at each of the selected analysis points (0th–10th; ) was calculated using results obtained with the tms-4 topographer. briefly, based on the refractive power and diameter of each mire ring (), a linear regression equation was created in each case. then, the refractive power at a specific point (0th–10th) […]

[…] result of different nibut patterns (e.g., central vs. peripheral dry spots); however, this study did not include dry spot patterns. , the quality of images is automatically determined by the corneal topographer. in our study, two images with high quality were included in order to avoid the risk of operator bias. our results suggest that, particularly in dry eye patients, repeated numerous […]

[…] docked onto the base unit, where the osmolarity value was displayed.non-invasive tear break-up time (nitbut), assessed using illuminated placido rings projected onto the tear film using the eye map topographer (alcon laboratories inc.). for each measurement, participants were instructed to look straight ahead into the device, where a placido ring pattern was projected on their tear film.

[…] surface is constructed.[] three pentacam models are available: basic, classic and high resolution., the galilei dual scheimpflug analyzer is a noncontact instrument composed of a placido-disc topographer and a dual rotating scheimpflug camera. both scheimpflug cameras are optically identical and are opposite to each other and aligned symmetrically to the rotation axis (slit of light).
