yes, you are absolutely correct, it is a very delicate tissue, and the procedure is very delicate as well.
I usually do it under surgical microscope (3D Stereo) with ultrafine microinstruments ( CASTROVIEJO Corneal scissor Angled to side blunt tips, and KRAMER Fixation forceps to get a good atraumatic hold of the eyeball, and CASTROVIEJO straight forceps without teeth to peel off the vitreous body away ) all under the seal of sterile normal saline, if you do not have the proper microsurgical instruments, and proper skills and training, the dissection will not be a successful as you desire.
I looked up an animation for you, I believe it is very descriptive.
