Purpose : To evaluate the effect of flipped implantation on the movement of ArySof IQ IOL.

Methods : 20 New Zealand white rabbits were divided into two groups of A and B. 10 rabbits in group A and 10 in group B. All the rabbits underwent phacoemulsification and Acysof IQ(SN60WF+20D) IOL implantation. We performed normal IOL implantation in group A and flipped implantation in group B. 14 days after surgery, we measured the intraocular lens movement induced by pilocarpine with Lenstar LS 900. The forward movement of intraocular lens was recorded as “+” while backward movement was recorded as “-”.

Results : All the IOLs were implanted in the capsular bag. No complication occurred during the surgery. 3 rabbits were excluded due to anterior chamber exudation which interfering the measurement of intraocular lens position. 2 in group A and 1 in group B. There were no difference between the two groups in age, gender(p>0.05). The movements in group A were -0.32mm to 0.11mm, with an average of -0.18±0.04mm. There was only one move forward in group A. The movements in group B were 0.04mm to 0.36mm, with an average of 0.17±0.05mm. The difference of movement between the two groups was significant(p<0.05).

Conclusions : The IOL movement was different after normal and flipped implantation. The intraocular lens mainly move backward after normal implantation while mainly move forward after flipped implantation.
