Objective To approach the clinical characters and therapeutic methods of retinal detachment(RD) after extracapsular catarat extraction(ECCE)with posterior chamber intraocular lens(PCIOL). Methods Sixty eight cases(68 eyes) of RD after ECCE with PCIOL were treated with sclerel buckling,microvitreo retinal surgery and intraocular gas,silicone oil injection and were reviewed. Results The retinas were totally reattached in 65 eyes(95.59%) which dropped to 94.12% in 6-60 months postoperatively.The resultant rate of visual acuity of the eyes with 0.1 or better was 79.41%,with 0.3 or better was 26.47%. Conclusion The main causes of RD after ECCE with PCIOL are similar to those of general RD,and most cases of RD after ECCE with PCIOL can be cured by surgical treatment.
