If you are suffering from symptoms of astigmatism, then you need to consult an Ophthalmologist who can treat your problem with a keratometer. In fact, you must know that a Keratometer, also referred to as ophthalmometer, is used often today by many Ophthalmologists across the world. It is nothing but a diagnostic medical instrument through which it is possible for you to measure the curvature of the anterior surface of the cornea. The Ophthalmologists, using this innovative device, will be able to assess the extent and axis of astigmatism.
Technology of Keratometry and Keratometer
The technology used for measuring astigmatism is known as Keratometry. It is the measurement of corneal curvature. You must know that corneal curvature determines the power of the cornea. The differences found in the power across the cornea leads to astigmatism. Hence, Ophthalmologists recommend Keratometer to measure astigmatism in a patient. However, this measurement can be obtained by using a variety of instruments as well. It can be done either manually or by using automated methods. In the automated method, a Keratometer, an USB auto-keratometer, is used mainly by an Ophthalmologist successfully. At first, handheld USB auto-keratometer was introduced into the global market. It is available in selected markets.
Handheld PalmScan K2000 Auto Kerotometer
This is a newly designed biometry device offered to Ophthalmologists, today. This is manufactured and sold by a company called MMD. This device is considered as a useful tool used by eye-care professionals. They suggest this important device to measure the corneal curvature and power, and in Cataract lens power calculations. Through this system, Ophthalmologists are able to quickly assess and measure the radius of the cornea of a patient and its associated curvature. The measurements achieved through Keratometer includes other parameters like corneal power, and steep and flat axis of the cornea of the eye. In other words, this handheld instrument provides the patient’s biometry prior to performing cataract surgery. It is a portable device enabling to hold it conveniently in the hand of an expert Ophthalmologist. This Keratometer can be connected to the USB port of a personal computer. This arrangement enables anyone to make the measurement of corneal curvature and power at the central 3 mm zone of the eye.
Results Achieved From Hand-Held Keratometer
It has been observed that the results captured through a Keratometer are precise and accurate. They are integrated automatically with the A200 A-Scan device for establishing IOL calculations, quickly. The question why Ophthalmologists recommend the use of Keratometer is that the results captured can help the user to minimize the chances of errors. In other words, it can be concluded that the adjustable capture threshold ensures the device for its capability of scanning all types of eyes. The portability features of this innovatively designed system permits the Ophthalmologists to use it in almost any location. This includes the operating room, which makes it an indispensable tool for the treatment of pediatric and wheelchair-bound patients, in an effective manner. Owing to the Keratometer’s unique application, Ophthalmologists of today, even suggest the use of this device for treating disabled patients. Besides, the device is considered as qualified for the ADA Tax Credit, in the US only.
With all the above features associated with the hand held Keratometer, most of the Ophthalmologists use this for executing safe cataract operations as it provides precise results.
