Be sure the technicians doing the biopsy are aware of your concerns, but having close realtives that have double cataract removal and lens replacement procedures here in the U.S., no such concerns were expressed by the surgeon/opthamologist...
Let the staff know that you've recently undergone the cataract op the previous day, and let them decide what they'll do, they'll probably go through with the procedure, but atleast they'll be aware of your concerns. Good luck for both your procedures.. :)
