Among refractive errors, astigmatism poses the greatest challenge to surgeons. Correcting an irregular shape requires complex treatment plans for lasers, precise alignment strategies for IOLs and nomograms for relaxing incisions. Surgeons must take into account that long-term results might be jeopardized by the natural repair mechanism of the cornea, which leads to “filling in” irregular gaps, inducing regression and the potential threat of IOL rotation.
