This man complained of
recent on-set right blurring of vision. He had had a right extracapsular cataract extraction and implant 10 years ago.
Examination showed decentration of the IOL with dislocation of the
superior haptic. It appeared that the cataract
extraction had been complicated and a superior iridectomy was performed possibly from
iris prolapse. The posterior capsule was
intact.
The blurring of vision was likely to be
the result of displacement of the IOL from progressive capsular fibrosis
and the absence of superior iris allows the superior haptic to be pushed
into the anterior chamber. The main risk to vision was corneal
decompensation from recurrent rubbing of the endothelium by the haptic.
He was advised to undergo re-centration of the IOL.

haptic, absent superior iris and significant posterior capsular
fibrosis.
