Batlimous, a Greek geographer, topographer
, mathematician and writer (2nd century AD), in his book named 'the World Maps' which includes 27 maps of the different parts of the world, has named the Persian Gulf as Persicous Sinous which means the Persian Sea.
This equipment is called a corneal tomograph because, in addition to capturing and analyzing information from the anterior surface of the cornea (by the reflection of Placido's discs), it also obtains data from the posterior surface (using a slit beam of light), unlike corneal topographers
based solely on reflection, which only captures information from the anterior corneal surface.
The global ophthalmology diagnostics and surgical devices market report provides market size estimates (Revenue USD million - 2014 to 2021) for key market segments based on diagnostic devices (autorefractometers, corneal topographers
, fluorescein angiography, fundus cameras, gonioscopy, keratometry, ophthalmic echography (ultrasound), ophthalmoscopy, OCT systems, pachymetry, perimeters, slit lamps, specular microscopy, tonometry), surgical devices (contact lenses, spectacle lenses, vision care, cataract, glaucoma, refractive, and vitreoretinal surgery devices), its applications (diagnostics, surgical, and vision care), and also forecasts growth trends (CAGR% - 2017 to 2021).
The VX120 system is a multidiagnostic platform that combines a Hartmann-Shack aberrometer, a Placido disk corneal topographer
, a Scheimpflug imaging-based system, and an air tonometer.
The Lensar Laser System with Streamline application upgrades include wireless integration with popular topographers
, iris registration, cataract density imaging, customised fragmentation patterns and arcuate incision planning.
He also welcomed today the topographers
syndicate headed by Antoine Mansour and dental labs syndicate headed by Alain Saqr.
A team of three topographers
from the Ge.Co Institute, Italy, performed the laser-scanner mapping of the settlement and of the funerary structures.
Regarding the level of works on the Absheron Peninsula, it can be noted that for the first time, given the paramount economic importance of the Peninsula, the Corps of Military Topographers
in 1910-1912 performed on its territory I class leveling lines in the form of individual polygons.
The latter was leased from the bishop of Llandaff as is evident from contemporaneous accounts written by well-known topographers
Geography is still history and this tremendous volume has been prepared by elite cartographers, topographers
and photographers," he said.
Written by ophthalmologists and optometrists from around the world, the 13 chapters cover basic topographic principles, including anatomy and optics and maps and scales; topographic techniques such as three-dimensional systems, Placido disk-based topographic systems, and combined topographers
with whole eye aberrometers; and applications for topography in corneal diseases, contact lens fitting, pre-refractive surgery topographic evaluation, planning topography-guided custom ablations and keratorefractive treatments, corneal biomechanics, and the integration of systems for calculating intraocular lenses.
The engineers did recognizance in the field to determine the final route with a team of specialized topographers
. The pipeline is located entirely underground with the exception of the fiver crossings and in some area of El Sillar, where the geological instability did not permit burying of the pipeline.
Frail and facile: during the late eighteenth century the simplicity of the technique, and its swiftness in capturing 'picturesque' turns of the weather, at first attracted jobbing topographers
such as Sandby and Rooker.
The team of archaeologists, topographers
, physical anthropologists and geophysicists also discovered a stretch of an old Roman road, which once linked Palmyra with western Syria and was marked with at least 11 milestones along the way.
