The aim of this study is to show the most successful way of performing the pars plana vitrectomy (ppv) in cases with dislocated intraocular lenses (IOLs).

Methods: The study included 18 patients with traumatic dislocated IOLs in the vitreal cavity. The luxated lens was followed by vitreal haemorrhage in 3/18 patients and retinal detachment in 2/18 patients. Emetropic were 7/18 eyes, hypermetropic 3/18, versus 8/18 myopic eyes. Ppv with anterior chamber IOL extraction, without using a buckle, was performed in all of the patients. Perfluorocarbon liquids were used in 4/18 patients. As endotamponade we used SF6 gas in 1/18, and silicon oil in 1/18 patient. 3/ 18 eyes remained aphakic, 9 achieved sulcus fixation lens and 6 iris clips lens.

Results: The best corrected visual acuity ranged from 0,1-0,90. Retina remained attached in all of the cases in a follow-up period between 3-18 months. Raise of the IOP was seen in 3/18 patients, and corneal decompensation in 4/18 patients in the first month. Toxic maculopathy because of residual PFCL was seen in one patient. In the majority of the cases we achieved good results in the visual acuity. None of the patients had retinal detachment (RD) as postoperative complication. Major of the complications were in eyes that underwent insufficient anterior vitrectomy, or in cases with anterior chamber lenses.

Conclusion: Ppv without using a buckle, and limbal IOL extraction seems to be a safety method for dislocated IOLs. When a good posterior vitreal separation is done, usage of PFCL in cases without RD is unnecessary. Sulcus fixated IOL or iris-clips IOL in the posterior chamber give as the best achieved visual acuity.
