A lot of machines, methods and ultramodern techniques are used in modern ophthalmology in order to treat eye diseases. OCT is used to conduct the necessary research and diagnosing.
Optical coherence tomography is a type of ophthalmic research with the help of which the doctor gets the scans of optically transparent eye tissues. The obtained images are characterized by high indices of spatial resolution.
A coherence tomograph resembles an ultrasound machine by its operation principle. However, the ophthalmic analogue uses optical radiation of the closest range of the infrared type instead of soundwaves for tissue probing. The probing radiation beam is concentrated on the tissues, while the interferometric measurement of the echo delay of the probing radiation is conducted. As a result, its reflection on the internal microstructures of the tissues on different depths is obtained. Along with the depthwise scanning, the scanning across the tissue surface is conducted during tomography process. It is done with the help of a special probing beam. As a result, a lateral unfolding of OCT-images is obtained.
In the course of research, conducted with the help of coherence tomographs, the specialists obtain data forming 2-dimensional cards of reverse reflections of optical microinhomogeneities of cellular tissue structures. Simply put, the information about morphological structure peculiarities of transparent tissues is contained on the optical tomograms.
The use of OCT presupposes application of fiber interferometers, which are characterized by high sensitivity. These are the devices that help to recognize useful signals, which are reflected by optical inhomogeneity in the depth of the objects under study. Application of an OCT guarantees:
When equipping a clinic or an ophthalmic consulting-room one should make a responsible choice of an OCT device. The manufacturers produce many models. Roughly, they are subdivided to:
The prices of some instruments can be as low as 8000 USD or less, while the newest, high-tier systems may cost as much as 70000 USD. The manufacturer plays a crucial role in making up the oct machine price. The more famous the brand the more expensive the machine, as the brand name itself says a lot about the quality and longevity.Heidelberg,Zeiss ,Optovue, Tomey are considered to be the most well-known. Besides, one should understand that new and demo optical coherence tomography machine will cost more than refurbished or used oct. What is the difference? New machines have never been used. They have the manufacturer’s warranty. Demo machines are, as a rule, exhibition models. They have not been used in clinical practice but they have been often presented at exhibitions. As a result, the price is lower. Refurbished machines are used machines that have undergone improvements (refurbishment can be done at the manufacturer’s facilities or in private repair shops)
