Abstract: Due to the instability of capsular bag, it has been a great challenge for  ophthalmologists to implant posterior chamber intraocular lens (IOL) in bag with efficiency and safety to deal with patient with subluxated lenses. Thus, some disadvantages may affect the effect of operation. In recent years, the appearance and widely use of novel auxiliary apparatus including, capsular tension rings, modified capsular tension rings, capsular tension segments, iris retractors and capsular anchor, which could protect capsular by different mechanisms to stable the subluxated lens, reduce further damage of ligaments and occurrence of crack of capsular in surgery, as well as keep IOL in center, decrease the shrinkage of capsular to prevent opacity of posterior capsule after surgery. All in all, they offer more choices for lens subluxation surgery.   (Int Rev Ophthalmol, 2013, 37: 317-321)
