Comment on: Predicted vs measured posterior corneal astigmatism for toric intraocular lens calculations

摘要

We read with interest the article by Shammas et al. on toric intraocular lens results. That various studies, including this one, have shown that it is preferable to rely on an assumption made by an algorithm, rather than on the actual measurement, is counter-intuitive, and reflects inaccuracy of the real assessment. However, from this, it cannot be concluded that a supposition about posterior astigmatism is better than its direct determination and devices with newer technologies will undoubtedly allow more reliable results to be obtained.
