Damages From Macular Grasping During Vitrectomy Comparing Traditional and 3D Microscope

Randomized, prospective, descriptive and comparative clinical study. The comparison is between a group of patients affected by macular pucker or macular hole, whose macular peeling is performed using a traditional optical microscope (Leica F40) - control arm, and a group of patients affected by macular pucker or macular hole whose macular peeling is performed by 3D heads-up microscopy system (NGenuity 3D, Alcon) - experimental arm.

It is a blind study for both the operator that collects data and for the statistician.
