Astigmatism Fix
Astigmatism Fix is a free online surgical calculator suite that uses a patient's manifest refraction plus the power and current position of an implanted toric IOL or ICL to determine the lens's ideal axis, the expected residual astigmatism at that position, and the probability of post-operative astigmatism after lens replacement.

Why it stands out
Built by ophthalmic surgeons Berdahl and Hardten and refined with data from hundreds of thousands of real cases since 2012, it accounts for confounders like surgically induced and posterior corneal astigmatism that simple steep-K or pre-op axis rotation misses.
