How does SiVIEW decide whether to prescribe a cylinder for a patient?

SiVIEW makes this decision based on a careful analysis of the cylinder’s relevance to the patient’s vision.

It depends on the amount of the power and the VA obtained but for example if the cylinder is small with an oblique or vertical axis, it compares the cylinder with an equivalent sphere, especially for young patients, to determine if omitting the cylinder might yield better or equivalent vision quality due to accommodation factors.
