Accommodative intraocular lens (IOL) tilting, the so-called Z syndrome, is a rare complication of Crystalens (Bausch and Lomb) implantation. We report a significant IOL tilting and subsequent high lenticular astigmatism due to posterior capsular fibrosis 2 months after uncomplicated cataract surgery and Crystalens (AT50AO) implantation. The attempt to correct IOL position with neodymium-yttrium-aluminum garnet laser was unsuccessful, and Crystalens exchange with in-the-sulcus, three-piece monofocal IOL was performed. Accommodative IOL tilting could occur early after the surgery. Laser capsulotomy may be the first intervention to restore IOL position, but patients with a higher amount of lenticular astigmatism may require surgical intervention and IOL exchange.
调节性人工晶状体（IOL）倾斜，即所谓的Z综合征，是植入博士伦公司的Crystalens人工晶状体后的一种罕见并发症。我们报告了1例在白内障手术及植入Crystalens（AT50AO）人工晶状体后2个月，因后囊膜纤维化导致明显的人工晶状体倾斜及随后出现的高度晶状体散光。尝试用钕钇铝石榴石激光矫正人工晶状体位置未成功，遂行人工晶状体置换术，植入了沟内三片式单焦点人工晶状体。调节性人工晶状体倾斜可能在术后早期发生。激光晶状体囊切开术可能是恢复人工晶状体位置的首选干预措施，但晶状体散光度数较高的患者可能需要手术干预及人工晶状体置换。
