Objective To discuss the treatment of retinal detachment(RD) after posterior chamber intraocular lents(PCIOL) implantation. Methods Twenty eyes with RD after PCIOL inplantation which were treated with vitrectomy combined with scleral buckling and intraocular tamponade from March 1993 to June 1997 in this institute were analysed retrospctively. Results The retinas reattached completely in 16 eyes and partly in 2 eyes after RD operation.The postoperative visual acuity improved in 17 eyes,not improved in 2 eyes,and decreasde in 1 eyes.The PCIOL was taken off during RD operative in 6 eyes.Postoperative complications including displacement of the PCIOL in 2 eyes,hyphema and vitreous hemorrhage were found in this series of RD operation in 1 eyes. Conclusion Vitrectomy combined with scleral buckling and intraocular tamponade is one of the effective methods to treat the eyes with RD with PCIOL. (Chin J Ocul Fundus Dis,1998,14:165-166)
