title: The optimal size of a posterior capsulotomy.
abstract: The optimal posterior capsulotomy diameter should be equal to the normal pupillary diameter in dark conditions to avoid glare and other undesirable optical aberrations. We studied 14 patients whose average pupillary diameter following cataract surgery was approximately 3.9 mm in scotopic conditions.
