Please suggest what type of anesthesia would be used in a complex cataract surgery?

Local: Most are done under local, unless there is associated trauma with the eye being open, or of course in a very young patient in which general is used by necessity. Complex cataracts in older adults with no other issues are ever so slightly safer with local anesthesia even though the surgery is more complicated.

Anesthesia Cataract: Depending on the case's complexity, pts's ability to lie flat & not move, & surgeon's experience, options include: topical (just drops, pts can stay still & lie pretty flat, not too complex case), peribulbar or retrobulbar anesthesia (pt moves eyes too much or more complex case), general anesthesia (pt is a child, or high risk case, or excess movement risk).
