[Management of dislocated or subluxated posterior chamber intraocular lens].


The experiences of the management of 20 cases (20 eyes) of intraocular lens (IOL) dislocation or subluxation were summarized in this report. All the patients underwent primary extracapsular cataract extraction with posterior chamber IOL implantation. The dislocation or subluxation occurred in 2 eyes intraoperatively and 18 eyes in 1 day to 3 years, post-operatively. The IOLs were captured at pupils in 12 eyes, dislocated into the vitreous in 4 eyes, represented as in westeast syndrome in 2 eyes and sunset and sunrise syndrome in 1 eye and 1 eye, respectively. Of the 20 eyes, 1 eye with mild sunset syndrome was treated with a miotic, 2 eyes with IOL pupillary capture were treated successfully by conservative therapy and the rest, by surgeries. In cases treated by operations, the IOLs were removed from original incisions in 3 eyes, by vitrectomies in 5 eyes and surgical reposition of IOLs were undertaken in 9 eyes with IOL pupillary capture of which 7 eyes were successful and in 2 eyes recurrence took place shortly after reposition. The causes and management of IOL dislocation or subluxation were discussed.
