The Wavefront Aberrometers is an instrument that is used in order to measure and diagnose the present refractive errors in the eyes. This device has the capability to calculate and identify the flaws present in the eyes as compared to the normal. The Aberrometers also helps in improving the overall vision correction and corrective eyeglasses.
Earlier studies had proved that the aberrometers device can be effectively used and can provide the patient with accurate measurement results within a very short time. However, most of the patients who had gone for the treatment, reported that there were some problems related to the hand-held aberrometer device. The Wavefront Aberrometers usually work on the principle of light rays interacting with the image in the display device. The main Wavefront Aberrometers components are the Wavefront Units, the optical axis, the sensor hand-held, the computer screen. The results of the testing are given either as a percentage of the average values or as a geometric mean. The Wavefront measurements are provided in different units like the degrees, the radii, the radiance, and the milli-seconds.
The aberrometers device has the ability to calculate the corneal thickness in inches with a simple hand-held instrument. However, the aberrometers device which is used for calculating the chromatic aberration in inches and in minutes can only be obtained from the software of Wavefront that can be downloaded from the internet. The measurement of wavefront aberrometers can be done with the help of different methods such as measuring the response time and the dispersion of light.
There was a significant finding that the aberrometers device can provide the patient with more than ninety percent accuracy which is far better than the previous studies and significantly better than the optical mapping that was earlier used.
