Abstract: Particular embodiments disclosed herein provide an apparatus and corresponding methods for guiding ophthalmic surgery and enabling a surgeon to switch, after initiating surgery, between a primary treatment plan and one or more backup plans. Switching between a first plan and a second plan may be performed while omitting presentation of steps of the second plan compatible with implemented steps of the first plan. A treatment plan may include guides imposed on a live video of an eye of the patient that has been registered with respect to a pre-operative image. When switching between plans, initiating registration with respect to the pre-operative image is omitted. A treatment plan may define steps for placement of an IOL such as incision, rhexis, LRI, crystalline lens removal, placement of an IOL, alignment of a toric IOL, and post-operative data collection. Upon switching between first and second, previously implemented compatible steps are omitted from presentation of the second plan.
