RESUMEN
To determine clinical features and outcomes of retinal detachments[RDs] following trans-scleral fixation of posterior chamber intraocular lens[PC-IOL], we reviewed the medical records of 249 eyes[239 patients] which had undergone trans-scleral fixation of PC-IOL and had been followed 6 months or longer. Retinal detachment occurred in 8 out of 249 eyes[3.2%]. The incidences of RDs were as follows:in 2/19 eyes[10.5%] with PC-IOL exchange for PC-IOL tilt, in 1/16 eyes[6.3%] with posterior capsule rupture during ECCE, in 1/26 eyes[3.8%] with ICCE, in 2/78 eyes[2.6%] with posterior capsule rupture during phacoemusification, in 2/106 eyes[1.9%] with aphakia, and in 0/4 eyes[0%] with anterior IOL exchange with PC-IOL. The sites of retinal break corresponded with the directions of needle during fixation in 5/8 eyes[62.5%] and all retinal breaks were located anterior to the equator. The timing of RD was between 2 weeks and 4.8 years after fixation although it occured within 2 months in most cases. Pars plana vitrectomy and scleral buckling were performed in 7 eyes and scleral buckling only in one eye. Retinal reattachment was achieved in seven eyes including three eyes which required two surgical interventions. The vitrectomy should be performed with meticulous care to reduce vitreous traction as much as possible during trans-scleral fixation of PC-IOL and a close follow-up examination for RD is required during the first two months.
