This video features side-by-side double camera angles so that we can simultaneously see the microscope view as well as the external view. This helps surgeons understand the positioning and angulation of the instruments as they are being used in cataract surgery. We can also see how the eye is kept in primary position by virtue of how the instruments are held in the incisions. There is a tremendous amount of learning that comes from videos like this and I encourage you to study this video in detail.
