Would this be considered a co-surgeon situation? Each surgeon, although both ophthalmologists, has his own specialty/subspecialty (ie, one is a vitreoretinal specialist/surgeon, the other is a glaucoma specialist/cataract surgeon). Although working together at the same operative session for the same patient/same eye, each did his own distinct procedure. The patient was being treated for a traumatic cataract and vitreous prolapse in the anterior chamber. First, the vitrectomy was performed by one physician, then the other physician attempted to remove the lens. During removal, a portion of the lens fell to the back of the eye. The physician performing the vitrectomy removed these remaining lens fragments, which completed the treatment.
