 It has been hypothesized that potential effects of laser Nd: YAG laser posterior capsulotomy may affect macular pigment as well as choroidal thickness, macular thickness and anterior chamber parameters, so it was aimed to investigate possible effects of Nd: YAG laser posterior capsulotomy on macular pigment optical density, choroidal thickness, macular thickness and anterior chamber parameters in cases with posterior capsule opacification in this study.
