Abstract: An intraocular lens (IOL) suspension structure includes a first fixing plate and a second fixing plate, fixedly interconnected by guide columns. A first moving plate and a second moving plate, slidably matched with the guide columns, are arranged between the two fixing plates. Curved needles are arranged on a left end face of the first moving plate through clamping mechanisms, and the clamping mechanisms are arranged on a right end face of the second moving plate. Auxiliary holders are arranged between the first fixing plate and the second fixing plate. The IOL suspension structure is ingeniously designed, functionally practical, and structurally simple. It effectively solves the problem in existing devices where curved needles on a first movable stage often fail to realign with connecting tubes on a second movable stage after passing through the eyeball and an IOL, significantly compromising surgical efficiency.
