Frequently Asked Questions
It is a tool that calculates the recommended toric IOL cylinder power and axis based on preoperative keratometry, steep axis, surgically induced astigmatism, and incision location.
The cylinder power is rounded to the nearest 0.25 diopter, which is typical for toric IOLs.
Residual astigmatism is the amount of astigmatism remaining after the toric IOL implantation, calculated as the difference between the corneal astigmatism and the combined effect of the IOL cylinder and SIA.
