Materials and Methods: 75 eyes of 73 patients with a history of cataract extraction having either IOL reposition or IOL exchange in our clinic was evaluated retrospectively from the patient charts. Visual acuity, the place of IOL implantation (either anterior or posterior chamber), the structure of GIL and indication of IOL exchange or reposition was noted.
Results: In the study 39 eyes underwent IOL exchange and 36 eyes IOL reposition. Of 39 eyes having IOL exchange 12 eyes had bullous keratopathy, 10 eyes incorrect IOL power, 7 eyes (one eye due to capsular phymosis and 6 eyes due to psoudoexfoliation) IOL subluxation, 5 eyes cataract progression secondary to fakic IOL, 4 eyes IOL opacification and one eye with fakic IOL experienced chronic inflammation. Of 36 eyes having IOL reposition 13 had zonular damage (12 eyes due to pseudoexfoliation and one eye due to ocular travma), 4 eyes capsular phymosis and 19 eyes IOL dislocation due to either one or both of the haptics remaining outside the capsular bag.
Conclusion: A significant number of eyes requiring IOL exchange or reposition may be prevented by the experience and cautiousness (vigilance) of the surgeon. Keywords : IOL explantation, IOL reposition
