The investigators will use the microscope with OCT (Lumera with RESCAN OCT) coupled to assess the extent, depth and change of retinal architecture in the perioperative period. Thus, they will evaluate what the optimal maneuvers of dissection of macular membranes to obtain a more satisfactory result of the rearrangement in the retinal layers. Furthermore, the use of OCT perioperative may dispense with the use of dyes, decreasing the concentration used or reduce the exposure time.
