Retinal Detachment Following Scleral Fixation of Posterior Chamber Intraocular Lens

ABSTRACT

The authors reviewed retrospectively retinal detachment(RD)s following posterior chamber intraocular lens(PC-IOL) implantation by transscleral suture fixation. One hundred twenty-two transscleral fixations of PC-IOL were performed from January, 1990 to December, 1992. The follow-up periods for this series ranged from 12 to 42 months. Six retinal detachments developed in this series. and the incidence of RD was 4.9%. There was no statistical difference between the primary operation group(unplanned posterior capsule rupture during extracapsular cataract extraction, lens dislocation/subluxation) and the secondary operation group(already aphakia after previous cataract surgery). The predisposing factors to RD were myopic eye(p=0.03), postoperative vitreous hemorrhage(p=0.001). In cases with RD, the locations of transscleral fixation sutures almost coincided with the meridians of the retinal breaks. The contributing factors to increased incidence of RD were thought to be vitreous loss during operations, vitreous traction by suturing needle or haptics of IOL, proliferative change by vitreous hemorrhage.
