Minus to plus cylinder calculator
To calculate the volume of a plus to minus cylinder, you will need the following parameters: Radius 1 (cm): The outer radius of the larger circular end. Radius 2 (cm): The inner radius of the smaller circular end. Ύψος (cm): The height of the cylinder. The formula for calculating the volume of a plus to minus cylinder is:Step 2: Establish Your 'Working Distance'. This correlates to your arms' length to account for the distance between your retinoscope and the patients' eye. If you have an average length arm, this is 67 cm which correlates to 1.50 D 'working distance'. This means you must SUBTRACT 1.50 D sphere from your retinoscopy findings as your final …
