Materials and Method: 25 eyes of 25 patients that had lens fragment dislocation into vitreous during cataract surgery were included in the study. In all cases conservative management including topical corticosteroids and antiglaucomatous drops were applied. Complications developed during follow up period and final visual aquity were determined.

Results: 25 eyes of 25 patients consist of 13 (%52) males and 12 (%48) females were included in the study. The age of the patients varied between 52 and 85 (mean age 67.76), and the follow up period varied between 6-24months (mean 14 months). In 24 of 25 patients posterior dislocation of lens fragments occured during phacoemulsification surgery, only in 1 patient dislocation occured during traditional extracapsuler cataract extraction surgery. The most frequently risk factors for lens luxation during phacoemulsification surgery was the presence of matur cataract. 10 (%40) of 25 patients had small fragments that wasx less than 1/4 of nucleus, and 11 eyes had dislocated cortical material only. 7 patients didn't come to follow up evaluation, the data were based on 18 patient with sufficient follow up medical records. In 2 of 18 patients intraoculer pressure rises over 21 mmHg . In 8 patients final visual acuity were higher than 0.3. Complications like uveitis, endolphtalmitis and retinal detachment didn't develope in any of patients.

Conclusions: ln the management of lens fragments dislocated during cataract surgery, medical management is a safe treatment modality for small lens fragments which does not cause complications. Keywords : phacoemulsification, cataract, lens dislocation.
