This tool estimates the power of the replacement IOL when a refractive surprise occurs after cataract surgery. It relies on a non-empirical vergence method, entirely independent of the usual IOL calculation formulas, using only the power of the IOL in place, the manifest refraction, the keratometry (K1/K2) and the cornea-to-IOL distance. For toric IOLs, it performs a full vectorial analysis and computes an optimal rotation angle presented as an alternative to exchange.
