Limbal relaxing incisions (LRIs) are a great option to treat pre-existing corneal astigmatism at the time of cataract surgery. They are best used for less than 1 diopter of corneal astigmatism since toric IOLs will do a better job for 1 to 4 diopters of regular, symmetric, corneal astigmatism.
We have also previously shown the technique of using paired full-thickness phaco incisions to treat astigmatism, but in most cases I find that I can titrate the effect of the LRI more accurately. This video shows a simple technique that even beginning surgeons can learn.
