Opacification of the C-flex 570C intraocular lens after sulcus fixation.
PURPOSE
To report a case of diffuse intraocular lens (IOL) opacification in a patient who started complaining of blurred vision in his left eye over the course of three years after having phacoemulsification surgery combined with capsular bag fixation of a C-flex 570C IOL. The IOL had been repositioned in the ciliary sulcus following its subluxation.


METHOD
An IOL exchange was performed, and the explanted IOL was sent for histopathological analysis.


RESULTS
Scanning electron microscopy identified multiple crystalline-like deposits on both sides of the IOL. The optic was more extensively involved than the haptics. Energy-dispersive X-ray spectroscopy confirmed the predominance of calcium within the deposits.


CONCLUSIONS
The breakdown of the blood-aqueous barrier seems to be a key component of this calcification process. Ciliary sulcus fixation is not a suitable option for C-flex 570C IOLs.
