Data-storage Requirement for EyeSuite Biometry Examinations

The data-storage medium should conform to the expected use of the device. The volume of data handled can be calculated as follows:

Standard measurement 1.8 Mbyte
Measurement with basic screen image 2.7 Mbyte

Example (moderate volume facility):

An average of 5 patients are measured on 250 working days. In the course of this, both eyes are each measured 5 times.

Standard measurement 250 x 5 x 2 x 5 x 1.8 = 22.5 GB / year
Measurement with red free (green light) image 250 x 5 x 2 x 5 x 2.7 = 33.8 GB / year

Example (high volume facility):

An average of 20 patients are measured on 360 working days. In the course of this, both eyes are each measured 5 times.

Standard measurement 360 x 20 x 2 x 5 x 1.8 = 130 GB / year
Measurement with red free (green light) image 360 x 20 x 2 x 5 x 1.8 = 200 GB / year
