Autorefractor keratometer and its uses
You must surely have come across autorefractor keratometer when you have gone to the oculist, but you might not have realized the equipment. This device is definitely usefuland though it has a complicated name, the uses it can be put to are extremely practical.
But do you really know what is the device used for? We can definitely break down the process to understand the procedure. It is for the beginners to know the basic function of autorefractor keratometer. The device measures the ocular power before the ophthalmologist or the oculist prescribes contact lenses and spectacles . The refractive error is parsed out by this device which works by measuring the deviation caused as the light ray travels back after getting reflected from the eye.
There is no discomfort or even pain felt by the patient when the machine is used. This makes the device greatly popular. When it is about the patient, it does not require him to do more than looking into the device where he can see the picture. The picture, in turn, continuously changes the focus and many measurements are taken to conclude when the image is received by the retina. Several measurements are taken and for final reading, the average is computed after which the results are followed and the patient receives the prescription. The ocular power can be best measured with autorefractor kearatometer. The method provides you with a greater accuracy than the earlier methods of judging the power by means of making the patient read out alphabets on charts kept at distance.
Throwing light on your eye the keratometer measures the cornea with the shape and then takes the measurement. Autorefractor keratometer is employed by the doctor for diagnosing other ocular problems like astigmatism.
Keratometer’s popularity contains in itself the two devices which are compounded to increase the convenience in using the device. With the use of the device both time consumption and error can be minimized. The device provides the utmost usefulness to the opthalmic industry. The keratometer benefits both patients as well as the doctors. The doctors do not have to invest huge time after one patient and neither do the patients have to wait with long appointments.
Though autorefractor keratometer is an excellent device, it cannot substitute the tests that are part of the opthalmic process. When the readings are taken in accordance with the traditional process, and compounded with the results shown by autorefractor keratometer, you get the best results.
