1069: Playlist: Astigmatism

Cataract surgery is designed to correct the cataract. Refractive cataract surgery is to correct the cataract and also the refractive error at the same time, thereby decreasing the dependence on glasses/spectacles and optimizing the visual acuity. An important part of the refractive surgery is addressing the astigmatism and these four videos highlight that topic. In general, for 1 diopter and above of astigmatism, a toric IOL tends to be my first choice. Whereas at 0.75 D of less of astigmatism, an incisional approach is usually my favored approach.

This complete case shows the initial marking of the toric axis and then precise alignment of the toric IOL.
paired phaco incisions can be used to address astigmatism precisely
Toric IOLs can be more challenging with smaller pupil cases because the iris can block your view of the toric alignment marks. This video shows how to overcome that.
If you have not done many Limbal Relaxing Incisions (LRIs), this video shows a simplified technique that is easy to learn.
