AER

Description

Returns the astigmatic effect ratio (AER) and the loss of astigmatic correction in percentage for a toric IOL that is misaligned (in off-axis position) by a certain degree.

Background
Toric IOL misalignment has dramatic effects on vision. Rotation of 3° decreases the astigmatic correction by 10%, and 10° by 35%, on average about 3.3% loss per degree. A total loss of astigmatic correction is seen at 30° misalignment, sometimes even earlier. Visual results may be worse than preoperatively even with the same magnitude of cylinder correction.
