Spontaneous late in-the-bag intraocular lens dislocation after can-opener capsulotomy: case report

We report a case of a 58-year-old man presenting with a spontaneous and late in-the-bag intraocular lens dislocation to the vitreous. A previous uneventful extracapsular cataract extraction with can-opener style capsulotomy and implantation of a polymethylmethacrylate three-piece lens was performed and, two years after the surgery, the patient developed capsule contraction syndrome with a fibrotic ring formation and dislocation of the intraocular lens. Although uncommon and related mainly to continuous curvilinear capsulorhexis, capsule contraction syndrome occurs in patients undergoing extracapsular cataract surgery with can-opener style and polymethylmethacrylate lens implantation, and can be the causative factor of intraocular lens dislocation.
