Spontaneous dislocation of intraocular lens as a late complication of uncomplicated cataract surgery: a case series

Five patients having uncomplicated phacoemulsification were implanted with CT-Asphina 603P intraocular lenses into the capsular bag. After a few months, three of the patients had haptic flexion anterior to the optic despite minimal capsular fibrosis. One patient had spontaneous dislocation of the intraocular lens into the anterior chamber with only minimal capsular fibrosis. Another patient had one haptic dislocated out of the bag. Late intraocular lens dislocation is also seen in newly designed preloaded intraocular lenses despite the absence of significant capsular fibrosis. Haptic-optic junction design and intraocular lens material play important roles in such complication. A slightly large capsulorhexis might be a deterrent for implantation of this intraocular lens.
