To measure eye refraction, autorefractometers exploit infrared radiation. The device operates on the principle of eccentric photo-retinoscopy: the device detects the smallest changes in fixing target brightness, correlating them with the conditions in which diagnostics is conducted. The examination provides detailed information about fundus condition and gives a reason to prescribe glasses or lenses.
Refractometry is used in ophthalmology to measure the human eye refracting power. The method allows identifying such diseases as:
Based on the results obtained, a doctor prescribes preventive, medicated, or surgical treatment to a patient. Nowadays, analog optical instruments are replaced with more advanced autorefractometers. Due to their utilization, the procedure duration was significantly reduced, and the refraction measurements accuracy was increased. This examination makes glasses and lenses selection procedures highly accurate.
Depending on the design, the devices can be:
A portable auto refractor is designed to conduct on-site examinations, fits the hand easily, can be connected to the electric mains, but more often uses the built-in battery power. Stationary machines are equipped with an external monitor, which to much extent simplifies the procedure and improves the examination accuracy. Corneal front surface curvature measurements, speed, and examination quality are significant advantages in stationary “computerized” refractometers utilization.
The most important technical characteristics of such machines are:
The prices of some systems can be as low as 1000 USD or less, while the newest, high-tier systems may cost as much as 25.000 USD.The manufacturer plays a crucial role in making up the price. The more famous the brand the more expensive the machine, as the brand name itself says a lot about the quality and longevity. Haag Streit, Topcon,Nidek,Tomey,Huvitz and ZEISS are considered to be the most well-known. Besides, one should understand that new and demo machines will cost more than refurbished or used ones. 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)
Manufacturing companies from Europe, Asia, and the USA are leaders in production of vision organs refractive power measuring equipment. The medical ophthalmology equipment price depends on the quality of optics installed, pre-installed software package, and processor performance. Special features availability, such as a built-in printer, maintenance complexity, or printing on thermal paper, affects the device cost as well.
