This study aims at assessing the effect of the posterior chamber accommodative IOL ; the 1CU in achieving pseudophakic accomodation to overcome the drawbacks of monofocal IOLs after cataract extraction. This IOL works by the optic-shift concept based on contraction of the ciliary muscles on accomodation, thus allowing the patient to read. In our study this IOL was assessed for the postoperative distance & near visual acuity. It was assessed for the occurrence of post-operative complications as glare, decentration & astigmatism. Long term study of the delayed complications as hinge problems, capsular bag fibrosis & post capsular opacification was also reported. This study included 25 patients with cataract. All patients underwent phacoemulsification. This IOL proved to be a truly accommodative IOL which allows good distance & near visual acuity but due to capsular fibrosis which occurs after sometime the accommodative effect decreases by time.
