Surgically Induced Astigmatism in Cataract Surgery (An Ophthalmology Against The Rule miniseries part 3 of 3)

We conclude our Ophthalmology Against The Rule miniseries on surgically induced astigmatism (SIA) by discussing the concepts of internal astigmatism, posterior corneal astigmatism, IOL tilt and decentration. Total SIA or internal SIA are commonly spoken terms but not often discussed or defined. We shed some light on what they are all about and whether they can be measured currently.
